The Formula (m/f, breast expansion) by TOABO Chapter One I knew the chemistry classes I'd taken would pay off eventually. I'd been experimenting with various chemicals forever, but I finally hit upon the magic formula. Magic, you ask. Yes, magic. The magic growth formula. I won't bore you with the excessively long story of my trials and errors that eventually resulted in that discovery. My research is probably not reproducible, but more importantly, it's dull. What happened afterwards is the part worth hearing. Like any good mad scientist, I tried out my chemical on myself. Crazy, I know, but I was so delirious with excitement, I wasn't considering the possibilities. After ingesting a small portion, I eagerly awaited results. At first, nothing happened. Seconds, then minutes ticked by. I was about to write off my first effort when I felt a tingling sensation. IT centered on my crotch. The sensation built and became almost painful. Despite the uncomfortable sensations, I began to get an erection. My dick slowly became engorged and the tight constrains of my jeans became quite unpleasant. Since I was alone in my room, I decided to alleviate the pressure by removing my clothing. Doing so, the size of my dick became all the more apparent. It seemed larger than normal. As I watched in amazement, I discovered this observation to be true. My cock was swelling beyond it's normal six inches. It slowly swelled to eight inches, then ten, then longer still. Its thickness was also increasing, more than doubling in diameter. My balls were also heavier and had swelled up as well. Finally, several minutes, the tingling sensation ceased. I surveyed my handiwork wit a lascivious grin. Thanks to my formula, my cock extended 12 inches. Its head was nearly the size of my fist. It's thickness was now comparable to that of a baseball bat. I would be a force to be reckoned with in the bedroom to be sure. "Ah," I thought, "there's the rub." What fun would it be in the bedroom without someone to share it with. However, I had prepared an alternative formula, designed to fulfill such a purpose, if it worked. Encouraged by my results, I decided to find a guinea pig for my next experiment. It wasn't hard. A female friend of mine lived down the hall. We had known each other since freshman year, so it wasn't hard to make some pretense to get her in my room. Sheila was friendly as always when I greeted her at the door. "Hey Saul! How are you? What's up with this vitamin supplement you're trying?" The supplement in question was my little ruse, so I responded encouragingly. "Oh, just trying to improve on the taste a little, and I wanted a second opinion." I handed her a glass with small portion of the female formula in it. She stared skeptically at the green liquid. "Is this stuff safe?" I assured her it was, and shrugging acceptance, she downed the contents. She wrinkled her lips. "A little bitter, isn't it?" "Yeah, it is. But it's way better from my first point. I couldn't swallow the stuff without gagging." "Well, there's still room for improvement." I nodded assent, but focused my attention her body. It wasn't the most spectacular of vistas. Her face was arguably cute and her body was trim, but she was no great beauty. Part of this was no doubt due to her lack of breasts. She did have breasts, but they were very small, just exceeding that of a preadolescent girl. She had no need of a bra, but wore one anyway, I suppose to avoid feeling like a slut. Now I would see if my formula could remedy that. I engaged Sheila in meaningless banter about classes, the weather, and other trivial topics. Time seeped by and she behaved normally. Nothing was happening and I was running out of conversation. Just as my impatience was about to get the better of me, Sheila began to trail off in her sentence and ceased talking. "You OK?" I asked with real concern. "I don't know," she mumbled after a few seconds. "I feel... funny, all of a sudden." I suppressed the urge to grin. Looking her over, nothing appeared to be different. Then I saw the slightest hint of an indentation in her blouse. Her nipples were getting hard. For a few moments it appeared that this was the extent of the transformation. However, very subtly the effect became more pronounced. Apparently Sheila's nipples were getting longer. The change continued for a little and then ceased. The change was slight but noticeable. No man would be unable to spot the arousal of Sheila's chest now. Not exactly a scientific wonder, but still an improvement. However, my formula was apparently not finished. After this initial pause, the protrusions in Sheila's cotton blouse became more prominent. A mass appeared to be forming beneath the clothing. Sheila's breasts were definitely growing. Given the confining nature of her bra, her flesh was pushed up and out. Though only one button was undone on her blouse, cleavage began to form where none had previously existed. As quickly as it started, the process stopped. Her breasts ceased to swell and leveled off about the size of apples. This apparently shook her out of her reverie, for her glassy-eyed stare was replaced with a look of concern. "What?" she mumbled. "My breasts, my breasts... what's happening to me?" She reached up and felt her newly expanded chest. "My God! I must have jumped a cup size!" Reaching behind her, she unhooked the snaps of her now too tight bra. Her breasts dropped down from their pushed-up position and her cleavage became less noticeable. "Saul," she said, "what's going on?" With a sigh, I opted for honesty. Sheila was not happy at first, but after further reflection that having breasts of average size would be better than having below average size. Besides, I told her, the change would not be very obvious to outsiders once she adjusted her wardrobe. In the end, Sheila thanked me and went one her way. Now I resolved to put my formula to use in a larger dose. I had only given Sheila a mere taste. Now it was time to see what a hearty swallow would do for a girl. For my next subject, I chose a more distant but more attractive acquaintance of mine. Jen Braddock and I were both in Student Government together, so I told her I needed help on a project for it. This was actually not much of a lie, so it made it all the more effective. Since she was an English major, I asked her to drop by and look at a speech I had written. She agreed and my plan was set. Jen arrived wearing an attractive cotton knit dress that hugged her curves, or at least, what curves she had. Jen was tall, slender, and beautiful. Her blue eyes had a sultry air to them almost constantly. She had a pert nose, graceful cheekbones, and slim lips currently painted a deep red. Long blonde hair framed this beautiful face and trailed halfway down her back. Her legs were long and supple due to her position on the dance team. In fact, she made quite a striking woman. Her only flaw was, like Sheila, a small chest. The tight fitting dress emphasized this discrepancy, showing the slight swellings and small nipples that accounted for her breasts. Unlike Sheila, Jen was confident enough in her sexuality to go without a bra, as was fairly observable thanks to the clingy fabric of her dress. She explained that she was going on a date in an hour, so she didn't have much time. That explained her dress. I showed her the speech and had her sit down. I then offered her a drink, which she accepted. I quickly spiked the glass of juice with a larger dose of the formula and handed it to her. Absorbed in the speech, she didn't notice. She quickly drank the concoction and proceeded to outline her opinions on my speech. I nodded absently at her suggestions, but focused my attention on her chest. It didn't take long. Perhaps something in the juice helped the formula be absorbed faster, or maybe it was just Jen's body chemistry. Barely a minute had elapsed before she began to fidget in her seat. As she fought to ignore the strange sensations coursing through her, I saw the tell-tale signs of her nipples poke more prominently into the dress. Subtly they thrust more insistently into the cloth. When her nipples had expanded approximately a half inch from their original size, Jen's breasts began to follow suit. Like the leading nipples, her tits altered very slowly. From the small bumps they were, her breasts became larger. As their mass increased, the fabric clung to them until it was pulled taut. Jen's chest reached and surpassed that of Sheila. Jen was numb with the shock of the drug in her system and the odd feelings it produced. Good thing she was sitting down. Focusing my attention back on her chest, I saw that her breasts had reached the proportion of large oranges. The cloth of her dress was now straining contain the mass of her breasts. Jen's tits were slightly flattened by the fabric of her dress and bulged noticeably out her neckline. Finally, her breast growth slowed and then stopped. As before, Jen was a few moments coming out of her daze. She eventually raised one hand to her head and moaned softly. Then, catching a glimpse of her chest, her eyes sprang wide open. She shifted her hands to her tits and inhaled sharply. "My breasts!" she shrieked. "My breasts!" "Take it easy, Jen," I urged. "You're OK." "But look at my breasts! They're huge! What happened?!" With a smile, I explained to her my little mischief. I expected her to be a little upset, but Jen went ballistic. After beginning by slapping me across the face, she began to berate me for my act. After a few long minutes of her tirade, she slowed down a little. "I can't believe you did this to me! I thought I was your friend!" "I am your friend," I said. "I thought I'd help you out by giving you breasts. Do you hate them that much?" "That's not the point! You fucked up my body!" she shot back. "Did I? What's wrong with your new look?" I asked. That gave her pause. "Well, I look all funny," Jen whined. "I think you look great!" I said with the utmost sincerity. "Well, I don't know." Clearly she was not so sure of herself anymore. While she thought a moment, Jen noticed the constraint of her clothing. "This dress is killing me," she said irritably. She reached around for the zipper in back and fumbled with it. "Here, let me help you, Jen," I told her. She glared at first, then turned her back to me. I grasped the zipper, and after a few tugs, managed to dislodge it. I could almost hear her dress sigh from relief. When she turned to face me again, I had to suppress my a leer. The dress no longer tightly gripped her breasts, but now appeared about to slip off. A wealth of cleavage was displayed to the eye. "You like?" she said wryly. "I don't know. How about letting me see the rest?" Jen sighed. "OK, might as well. They are your creations after all." With that she let her dress fall the rest of the way off. Jen's breasts were terrific. Almost perfectly round, they looked like swollen grapefruits. Her nipples were even better. As thick around as my thumb, they began to stiffen and extended to just under an inch. "You look incredible! I've never seen breasts like that before. I thought you were pretty to begin with, but these tits make you drop-dead gorgeous!" Jen blushed slightly at my effusive praise. "Yeah, well, I guess they're OK." "Well, they've certainly got me hard!" returned, gesturing at the side of my leg. The inside of my shorts appeared to be storing a salami, and the tip of my apple-sized head just extended beyond the hem. "My gosh! I'll say you're hard! Your cock is big!" Jen's eyes were now locked on my dick and a lusty leer splayed across her face. "Tell you what, I'll show you mine since you showed me yours," I offered. I dropped my hand to my crotch and undid my pants. Jen protested half-heartedly, but I proceeded. I dropped my shorts to the floor, and then my boxers. Freed from its enclosure, my massive 12 inch dick jutted up. I stepped closer to Jen, who took a small step back in response. I stepped closer and the head of my dick lightly brushed her stomach. "Oh God!" Jen whispered. Clearly she was really turned on. I took advantage of the moment and leaned closer and locked my lips on hers. Jen initially resisted, but soon she was returning my kiss with great fervor. While we exchanged saliva, I raised my hands to her marvelous mounds. Kneading them softly, I rubbed my palms over nipples, feeling their hardness. Breaking off our kiss, I began licking her breasts. Zeroing in on one stiff nipple, I suckled her like a newborn babe. Jen moaned loudly and wound her fingers into my hair. I continued my trip south and pushed her dress all the way down. Her silk panties concealed her pussy, but a large wet spot was forming over the center. I licked her a few times through the fabric, eliciting gasps of pleasure from above. Moving the sopping silk aside, I looked at her lovely womanhood. Her cunt was sparsely covered with hair and was glistening with moisture. I located her swollen clit and flicked it a few times. Jen went over the edge and shook her way through a quick orgasm. I stood up and kissed her again. IT was a long, deep kiss, full of the passion between us. "Saul," she breathed into my ear, "I want you. I want you now." I needed no further encouragement. Positioning myself carefully, I placed the head of my dick at her entrance. I leaned forward and pushed gently. Jen inhaled sharply as I penetrated a short distance. My mass was a tight fit despite the large amounts of lubrication. Pressing Jen up against the wall, I inched further in. Her moans grew louder the further I penetrated. About three quarters of the way in I hit bottom, drawing a grunt from her. I began to piston my hips in and out of her, slowly at first, then faster. Jen's nails dug into my back as her passion increased. She raised her legs and locked her thighs around my waist. I slammed into her again and again, as I roughly squeezed her tight ass. Her cries rose in pitch and I felt myself coming close to release myself. Jen's body at last shuddered violently and her hot cunt clamped down on me like a vise. This did it for me and I erupted deep inside her. It felt like I came for several minutes. (Given the size of my balls, it is possible I did) For several minutes we were motionless as I leaned into the pillowy softness of her breasts. We at last released our hold on one another and disengaged. I thought Jen stilled look very attractive, despite the her disheveled hair, flushed face, sweat-coated body, and sticky crotch with the white trace of cum leaking from her reddened cunt. I smiled at her, which she immediately returned. Stepping over to me, she kissed me softly. "What's that for?" I asked. "For the best sex I've ever had!" she said, eyes gleaming. "My pussy is going to be sore for a week after stuffing that monster cock in there! And you came forever! Good thing I'm on the pill." She paused. "So, now what?" "What do you mean?" "Well, it's going to be hard to explain these," she said, nodding at her grapefruit-sized breasts. "A loose shirt or a minimizer bra sure won't conceal these babies. Heck, I bet most of my clothes won't even fit me now." "Not to fear," I assuaged her. "I have a counteragent which should work." I whipped out the orange formula from the fridge and prepared a small dose for her. "Here, drink up." Jen did as I bid. As before, nothing happened at first. Then Jen's brow furrowed. "Something's happening," she murmured. Sure enough, Jen's breasts were changing, but this time the process was reversed. Her tits slowly deflated like balloons. Over the process of a few minutes they went from grapefruits to oranges to tennis balls. Her nipples also diminished somewhat, shrinking down to the size of pencil erasers. When the process at last finished, Jen's chest had returned to almost normal. She grinned widely at the results. "Well, that's not quite as small as usual, but that's OK. I don't think anyone will notice the difference. " She gathered up her clothes and quickly made herself presentable in public. She was right; her chest looked only slightly fuller beneath the dress. She went to the door and then turned back. "Thanks, Saul." Then she was gone. Thanks, indeed. The Formula Part 2 by TOABO It was a while before I heard from Jen again. I was afraid that I might have scared her off with the mad scientist experience. Then I got a call from her asking for a favor. “I’d like to borrow some of your formula. You see, my roommate is, Amanda Smith.” Amanda Smith, did I ever know her. Every guy on campus knew her. She was one of the Top Ten babes at school to be sure. She had a pretty face, but a knockout body. Her greatest feature was her chest. A pair of D-cups lurked beneath her sweaters, though she was not above flaunting her cleavage just to tease the guys. “Anyway, you know she’s got big breasts and she just loves to drive the guys crazy. She’s OK most of the time, but she can be real snobbish about her tits. Thinks because her chest is so much bigger than mine that can lord it over me. I’d put up with it till now, but I think with your help I can beat her at her own game. What do you say?” I thought a moment. “It sounds intriguing, but what do I get out of it? After all, this formula is not easy to make.” “Well, you get to take down Amanda a notch,” she replied. I had to admit that had appeal, because Amanda was a notorious tease. She loved to show off her tits to a guy, but then leave them hot and bothered. I had a few friends who would probably like to steal some of her thunder. But all the same, Amanda had never done me wrong, or right, or really anything at all to me. “I don’t know, Jen,” I stalled. “I don’t really know Amanda.” Jen paused. “OK, I’ll let you go another round with me. I don’t really want to - my pussy still aches some from your gigantic dick - but if that’s what it takes...” I pretended to be slightly miffed, but in the end I accepted. Jen set up the meeting for the next night. I arrived at her dorm room with my potions in my backpack. Jen introduced me to her roommate as a study partner. Amanda lost no time in beginning to flirt with me. She was wearing a tight cotton shirt which revealed more than a little cleavage. It was easy to see why so many guys found her attractive since I was becoming turned-on already. She was quite good at getting a rise out of me. After a few minutes, Amanda excused herself to pick up her laundry from the dryer. Jen had planned on this diversion and quickly hustled me into action. I prepared a dose of the green formula from my bag. “How much,” I asked. “I don’t know. I want to really show her up though, so its got to be bigger than hers for sure.” I nodded, and doled out slightly more than the D-cup dose I’d given her a few days before. “This ought to be enough for a pair of DD’s, at least.” “Good!” As I packed up, Amanda reentered the room bearing a large laundry basket. She set it down and began folding her clothes. After a few minutes, she stopped. “Jen, you got some of your bras in with mine again. See?” Amanda said, holding up a small cotton bra that was clearly an A-cup in one hand. Jen’s face clouded. “Oh, I don’t know how that happened!” she said with a slight edge to her voice. I guessed that Amanda had probably planted one of Jen’s bras just to embarrass her, most likely for my benefit. “Oh, don’t worry about it. Just remember that yours look like this,” she responded, waving the small bra, “and mine look like this.” With that, she produced a red, frilly bra that was considerably larger. Jen’s blush deepened and her eyes narrowed. She wordlessly retrieved the lingerie from Amanda. I could see why Jen was so eager to get back at her roommate. Amanda looked over at me and winked. “In fact,” I don’t even know why you bother to wear the thing. It’s not like you have a real chest to support.” She didn’t say it, but it was clear she meant “a chest like mine.” Then Amanda casually caressed the side of one large tit to emphasize the unspoken point. I was flabbergasted; this girl was outrageous! I would look forward to seeing her get taken down a peg. I glanced over at Jen. The glass was now empty; she must have used Amanda’s last exchange to drink the formula. “Well, Amanda, maybe you’re right,” Jen said. “Maybe I should start wearing a real bra. Like you.” She then went over and picked up the red one that Amanda had so recently angled in my face. Amanda was a little perplexed at this, but Jen’s next move really confused her. Jen took off the T- shirt she was wearing, briefly exposing her tiny tits. She then put on Amanda’s bra. “There, what do you think?” she asked. The picture was fairly ridiculous. The bra completely covered her breasts and was so loose that it appeared about to slide off her tiny curves at any moment. Amanda shot a glance at me and then replied in mocking tones. “Well, Jen dear, it seems a little...loose.” She paused and an evil grin flitted across her face. “Maybe you can GROW into it!” she belted forth, an then she dissolved into giggles. Jen resolutely held her ground. “Good idea, Amanda, good idea.” Then, as if on cue, her breasts began to swell. Her nipples were barely visible behind the lacy covering, but they appeared to extend further into the bra. Her breasts expanded and began to fill up the bra. Amanda was no longer laughing. I looked over to see her face register a look of surprise at this bizarre development. Jen’s breasts continued to grow. They again became large oranges which rounded out the bra fairly well. Then they swelled into grapefruits about the size of Amanda’s. The bra conformed nicely to her generous mounds. Jen was not done yet, though. Her tits kept on increasing in diameter, filling the bra to capacity. At last her breasts leveled off at the size of cantaloupes. Amanda’s bra was now a bit too tight, forcing Jen’s tits up and out for a marvelous display of cleavage. Her nipples were also erect, making notable protrusions in the lacy fabric. Amanda was aghast. Right before her eyes her flat chested roommate had grown larger than she had ever been. “What? What?” she stammered. Jen grinned triumphantly. “Gee, Amanda, your ‘real’ bra seems kind of small. See?” With that, she stepped up to where Amanda and thrust her shoulders back. I could almost hear the bra groan under the strain as Jen thrust her massive breasts out into the bra. Her cleavage welled up even further and threatened to spill out. Amanda just stared in frightened shock at Jen’s now large chest hovering inches away from her. “What, don’t you have anything to say?” Jen asked sarcastically. “Funny, you’re usually full of little comments. You usually have plenty to say about my breasts. Look, you even have an audience,” she said, gesturing at me. “Where’s your ‘Look My Big Titties’ act?” Amanda flinched slightly at this barb and her lower lip began to quiver. Jen continued her tirade. “What, is it suddenly no longer funny when the tables are turned? You don’t like to feel inadequate? You don’t enjoy being embarrassed in front of a guy? You surely have done that shit to me! How’s it feel to be the object of ridicule?!” Jen was practically shouting now. Amanda lost all reserve and started sobbing. “I’m sorry” she blubbered. “I’m sorry! I was just trying to be funny! I didn’t mean to hurt you! I’m sorry, Jen, I’m so sorry!” “Awww, isn’t that just too damn bad. Now you’re apologizing. Well go ahead and cry! You can-” “Jen,” I interrupted softly. “What?!” she rounded on me. Her face was flushed with anger and her chest was heaving While I admit the chest heaving was interesting to watch, the fire in her eyes and the cold smile on her lips were not. “I think she’s had enough. You made your point. Let it go now.” Jen stared to reply then bit it off. “OK, I guess you’re right.” She looked over at Amanda, who was crying softly into her hands. “I’d better talk with her.” “Yeah,” I replied. “You want me to stick around?” “No, I think this is something we’ll have to work through together.” “OK.” I swore softly to myself; I wouldn’t be getting anything tonight. I quickly gathered up my things and prepared to go. “So, can I get a dose of the orange before you go?” “Oh yeah, sure.” I prepared one quickly and gave it to her. “Just make sure your roommate doesn’t get into this. I don’t think she’d be able to handle having no tits.” Jen grinned at that. “Yeah.” She kissed me on the cheek. “Thanks for helping me. I may have been hard on her, but I think she’ll be better for it.” I nodded and made my farewells. Some evening this had turned out to be. I decided to make the best of it and headed off to the lab. I had some new chemical variations I wanted to try out. The next day I dropped by Jen’s to see how she was doing. When she met me at the door, I was surprised to see that beneath her loose blouse that her breasts were still the size of plump oranges. I was about to ask if I hadn’t given her enough of the reducer when Amanda came in from the bathroom. Her tits were noticeably smaller, about the same as Jen’s presently. I looked at Jen expectantly. “Oh, well Amanda and I decided to try a little compromise last night. She’d try life with smaller breasts and I would keep mine bigger. What do you think?” “Very interesting. What do you have to say, Amanda?” She smiled, this time friendly and not like a tease. I felt it made her much more appealing. “It’s different, not having all that weight. Oh, Saul, I just wanted to apologize for my behavior last night. I was really rude and I shouldn’t have flirted with you like that.” “Don’t worry about it,” I told her. I turned back to Jen. “So what’s up for today?” “Well, Amanda and I planned on going to the carnival that came to town last week. You want to tag along?” I agreed and we were off. It was a really fun day. Jen and Amanda giggled like schoolgirls the whole day through. Their entire relationship had altered overnight. I couldn’t help but join in the laughter. It was also different to have two pretty girls tagging along with me. On the one side I had the blonde, slim Jen; on the other was Amanda, raven-haired and curvy. A blast was had by all. It was well into the night by the time we returned back to campus. I walked the girls back to their room. I bid them a good night and was about to leave when Amanda stopped me. “Saul,” she said, “I want to thank you. I had a great time today and I owe a lot of it to you and that chemical of yours. I really owe you.” “Yeah, I replied, “you and Jen both.” Don’t worry about it though. I had a good time with you as well.” “What does Jen owe you for?” Amanda asked. Jen blushed slightly as she remembered our previous agreement. “Well, I sort of promised Saul that I’d sleep with him again if he helped me get back at you.” “Oh really,” Amanda said. She paused a moment then looked at me. “Saul,” she began, “is it true what Jen says about, you know, the size?” “The size ? Oh, you mean...” I trailed off with a glance downward. Amanda nodded vigorously. “Well, I guess so. It depends on what she told you.” I glanced pointedly at Jen, who was blushing more. “Jen told me she’d never seen one so big in her life.” Jen was getting really red at this point and started to interrupt. However, I jumped in first, not wanting her to change the subject. “I suppose that’s true. Would you like to see for yourself?” Amanda began to redden at this, but managed to shake her head affirmatively. I unzipped my jeans and dropped them to the floor and kicked them off along with my shoes. I then dropped my boxers, exposing myself to the women. “That’s it?!” cried Amanda. “That’s the giant dick?!” Jen appeared equally surprised, for my cock appeared no more than five inches long in its flaccid state. “Easy, easy,” I replied. “I made some improvements. Arouse me.” Amanda paused, looking at me. “Go on,” I urged. Sighing, Amanda did as I bid, and began to fondle my balls. I quickly began to respond. My cock stiffened and extended, becoming a little over six inches long. Amanda looked back at me. “So?” she inquired unconvinced. “Keep on. Try sucking it.” She shot a glance over at Jen, who merely shrugged in confusion. Amnda rolled her eyes and knelt in front of me. Taking my cock in her hand, she brought the head of it to her lips. The sensation was delicious. She ran her tounge around the tip and began to draw me deeper into her mouth. My cock responded by growing. Amanda’s eyes widened as my dick suddenly reached to the back of her mouth. She renewed her efforts with gusto, making loud slurping noises as she sucked me. Then she was no longer able to get it all the way in her mouth. The thickness was also increasing and soon Amanda had to drop her jaw to fit my manhood between her lips. I, too, was struggling, trying to keep from cumming. However, I was to lose this battles. With a loud grunt, I exploded and shot ribbons of jism down Amanda’s throat. She attempted to swallow as best she could, but a trickle of semen rolled down her chin nonetheless. After sucking me dry, Amanda released her hold on me. “Wow,” she breathed, “I’ve never seen anything like it.” My cock now stood half- erect at around 10 inches. “How’d you get it to grow like that?” “Genius, my dear, genius,” I replied. “I altered the formula so it activates when I get an erection. That way I don’t have to carry around a big dick all day. I just keep it normal-sized until I need it.” I looked over at Jen, who was breathing heavily and whose hands absently massaged her tits. I smiled; she’d gotten pretty turned on by seeing her roommate suck me off. “Hey, Jen,” I called, “want to try it?” “Sure,” she replied. She approached and began with a kiss. I dropped my hand down to her skirt. Feeling underneath it, I found a very moist set of panties. Jen started at my touch and broke off the kiss. “Wet already,” I told her with a grin. Using both hands, I pulled down her underwear. I then inserted one finger inside her. It slid in easily. “My, you are hot. Best get started then.” I went over to one of the beds and laid down. “I want you on top this time.” Jen grinned in response and followed me onto the bed. She straddled me in a half kneeling position. Grasping my warm cock in her hands, she positioned me carefully. Slowly dropping, the head of my dick penetrated within her. Inch by inch, her cunt swallowed my dick deep inside her until our pubic hair mingled together. Still fully clothed, Jen smiled at me from above. I let the heat of her interior seep into me and felt my cock respond. She squealed as it expanded inside her. “Oh God!” she cried. “It’s growing! Oh my!” Jen began rhythmically rocking her hips back and forth. Her pussy became tighter and tighter as I expanded within her. I soon felt the head press more and more firmly into Jen’s cervix until at last that muscular barrier parted to allow me entrance. We were both breathing hard as we ground our pelvises into one another. “You’re splitting me apart! Oh God!” Jen’s cries dissolved into a series of incoherent screams of pleasure/pain. The sensation was overwhelming. Jen began to tremble and then shudder violently as she went into the throes of a powerful orgasm. I followed suit moments later as I came for a second time. Jen collapsed on top of me, my cock still buried deep inside her. I looked over to see what Amanda was up to. She had apparently been as equally turned on by Jen’s passion as I had, for she had shed her clothes. Sitting in a chair, she was spreading her pussy lips art with one hand while rapidly rubbing her clit with the other. Her head was tossed back and her eyes were tightly shut as she focused upon the task at hand. Her breath came in gasps as she grunted from her masturbation. Finally, she achieved the release she sought and her body quivered. I smiled. It was good to see everyone was having a good time. Jen recovered and got off me. My cock made an obscene sucking sound as it slid out of her. I glanced at the clock. It was after 3 AM and I had to get up in a few hours for class. Looking over at Jen, I could see she was tired and probably a little sore as well; she was not likely to want to go another round on Saul’s “Wild Ride” tonight. She offered no resistance to my departure and Amanda followed suit. I bid both ladies a good evening and went home. The Formula Part 3 by TOABO The next few days went by in a blur. Tests were taken and papers were written. I am not totally against school, but sometimes it can be a real drag. I was relieved when Wednesday night came and I could relax. I needed some recreation to balance out my hectic week. Luckily for me, I didn’t have to go looking for entertainment. Jen, the ever crafty, had devised a new way to employ my chemical skills. “Saul,” she explained on the phone, “I’ve been thinking of it all week. Your new collapsible cock got me going, so I’ve been looking for a way to have some fun with it. Now I think I have it. Do you know Shirley Wallace?” I told her I didn’t, so she filled me in. “She’s one of my sorority sisters. Her nickname is ‘The Cavern.’ We call her that because she’s got the biggest cunt in the sorority.” I coughed. “Umm, just how the hell do you know that?” I asked. “She won the competition.” “Uh-huh. Competition?” “OK, here’s the deal. When you join our sorority, part of the pledge process requires you to undergo a bunch of ordeals and stuff. One of them is ‘Biggest Breasts,’ which I lost miserably. Too bad I didn’t have your stuff back then.” I could almost hear her grin across the phone. “Another one is the ‘Deepest Cunt’ competition. The sisters get this giant collection of dildos together and set them out by size. Each pledge has to stuff one in and the one who can fit the biggest one in wins. Shirley got a 14 inch neon green rod inside her.” “Wow. That’s pretty damn big,” I said. “I’ll say! Yours is probably only a foot or so and I can barely contain it. The sisters couldn’t believe it. She’s the only one to ever do the ‘Green Monster’ that the sorority can remember.” Jen snorted. “Hell, they’ll probably make her President because of it. If she had bigger tits they’d probably had elected her on the spot.” “OK, so you have strange pledge rituals and you choose your officers by physical appearance. The first is pretty typical of the Greek system and the second might be a bad thing, but they don’t have much to do with me.” “No, no, no! I want you to fuck Shirley with that salami of yours!” “Why? She ought to be able to fit it in OK.” “Well, I was hoping you can make your dick bigger. You know how I overstuffed Amanda’s bra? I want you to do the same to Shirley’s cunt.” “Intriguing, but why?” “Same reason really. I want to take some of the wind out of her sails. She still thinks she’s pretty hot shit. She has a bit of an attitude, but no one in the sorority is really in a place to tell her not to. After all, we believe it’s important to be proud of yourself, although I think this is taking it a bit far. It just be nice if you could kind of show her that she can’t handle every dick out there.” I sighed. “Am I just a tool for your personal vendettas? What’s next after this? Going to get back at someone who dumped you for someone with bigger breasts? Will I have to shrink the cock of some guy who pissed you off?” “No, Saul!” she pleaded. “C’mon, this is the last one, I promise. Although there was a guy in high school who dropped me for Sarah Freels...” “Jen!” “Kidding, kidding. Seriously, though, I think this will be good for Shirley. She needs to get down off her high horse. Besides, you’ll probably enjoy it.” I let that last comment go, particularly because I probably would enjoy fucking Shirley. “What makes you think she’ll even consider it?” I asked. “Simple. I’ll tell her about you. You see, since Shirley won the contest, she’s been sort of a prize fighter. Take-on-all-comers, if you know what I mean.” She ignored my groan at her pun and went on. “What happens is someone will hear about a guy on campus who is supposed to have a big dick. Shirley will track him down and sleep with him. Then she’ll come back and report. Oh, and don’t doubt this. You guys are easy to manipulate. Show some cleavage and flash a little thigh and you guys will be in bed like that. So far she hasn’t lost, so to speak. I just think she’s due for a defeat. I agreed, reluctantly, and said I’d go through with it. “You still owe me though, and this time I’ll name the price. I’ll let you know when I decide what it’ll be.” Jen didn’t like the uncertainty, but acceded nonetheless. “I’ll let Shirley know about you soon. Expect her to come calling in the next few days.” Jen was as good as her word, for I met Shirley less than 24 hours later. I was in the library doing some research when someone cleared their throat behind me. I turned around to find an incredibly lovely vision standing behind me. The young lady had red hair which, I must say, is a very big-turn on for me. Green eyes sparkled above a cute nose and a full-lipped mouth. She wore a black halter top and matching skirt. The top left both shoulders and navel exposed, granting me a view of alabaster skin. The skirt gave me an equally expansive vista of firm legs. Though not busty, her chest was sufficient enough to give her decent cleavage, accentuated by the tight confines of the halter top. The lovely creature spoke. “Excuse me, are you Saul Larson?” “Umm, yes, yes I am,” I stammered. She smiled. “Hi, I’m Shirley Freels.” “Nice to meet you,” I replied. Very nice. “Likewise. I’m a friend of Jen Braddock.” I nodded in recognition and she proceeded. “Well, she told me about you and how you were a really nice guy and that I ought to meet you. So, here I am.” I was at a loss for words; her appearance and breathy voice were already beginning to stir my loins. “Ah, so you are.” Lame, I know, but I was never known for my suave pick-up lines. Why do you think I ended up in chemistry? Shirley appeared unfazed by my noncommittal reply; I guess she was used to guys being confused by an aggressive woman. “Well, I was wondering if you’d like to go out some time. How’s tonight?” “Sure, great. Tonight’s fine, just fine.” I could feel myself gushing. Damnit! Shirley was wrapping me around her little finger already. “That’s good. How about you pick me up at my room at 8?” “Sure thing.” “See you then,” she said, and then she breezed away. I let out a huge breath and inhaled the remnants of her perfume deeply. Jen wasn’t kidding; I was putty in the hands of an attractive woman. The rest of the day flew by in anticipation of the big night. I was always slightly nervous before a first date, but I approached this one with almost dread. I had the unsettling feeling that I was being lead to slaughter like an ox. Even backed my the formula, I still worried that Shirley might eat me alive. At the appointed hour I arrived at Shirley’s dorm. I wore pants and a long-sleeved dress shirt and carried a yellow rose. As I traversed through the building, someone exited a room ahead of me. As I drew closer, I was able to tell it was Shirley’s room. The woman, who was probably Shirley’s roommate, smiled at me as I passed; I noticed, though, that she fought to keep the polite smile from becoming a smirk of laughter. Evidently she had seen guys like me show up for her roommate before. Given Shirley’s track record, I could see why mirth might be a normal response. I swallowed nervously and knocked upon the door. “Come in. Door’s open.” I did as I was instructed. The room was typical for a dorm. Two beds, two desks, and a variety of posters were the primary features. Shirley was not in view, but I could see a light emanating from the half open closet. This proved to be the case when the door swung open. I involuntarily drew a quick breath. Shirley was wearing a loose silk robe that gapped at the top. Her breasts were covered, but it was clear that they were unrestrained by a bra. The blue fabric clung provocatively to her many curves and ended well above her knees. Her red hair hung loosely over one shoulder and her green eyes glistened. As she moved towards me I was reminded of nothing so much as a tiger, stalking its prey. “Umm, hi, Shirley. You, umm, look, um, nice.” I was clearly unnerved. “Hi, Saul,” she purred. “Thank you. I’m glad you like it.” “It’s a pretty color,” I replied. “Really brings out your eyes.” She grinned, exposing white teeth. “I think so. too. It’s part of a matching set.” As she said this, her hands went to the loosely tied knot at the waist that held the robe closed. It came undone with the slightest of tugs and the robe parted further. The movement exposed the sides of her breasts, which appeared quite firm. I traced a line down her torso, dragging my eyes from her chest down to her slim stomach and cute navel. My gaze dropped lower and my pulse jumped. Below her trim stomach Shirley wore a pair of silk panties the exact shade of blue as her robe. Her mound was high and round. I could almost see her pussy lips outlined by the fabric. “Very nice,” I breathed. “Oh, but the best is yet to come,” she replied. With that, she shrugged off the robe. Her breasts were about the size of tennis balls and were surmounted by stiff nipples. She stepped to within inches of me and instinct took over. I took her face in my hands ad brought her willing lips to mine. I felt her breasts press into my chest as I crushed her body to mine. Her hands roamed over back and then down to my legs. Feeling the inside of my thigh, she cooed softly as she found my already raging erection. Gazing lustfully into my eyes, she opened my pants. I quickly unbuttoned my shirt while she finished undressing me. Freed from its confines, my dick surged forth. It was a respectable 8 inches, but I caught a look of disappointment in her face. Apparently she was expecting more. Too polite to bring this up or perhaps just too willing to fuck someone, Shirley managed a half- smile. “Ooh, this is a nice one,” she said, and kissed it with her crimson lips. I moved to take her in my arms again, but she held me off with an upraised hand. “Hold on, let me get a condom.” Well, at least she was prepared. As she turned to go to a drawer, I stroked my length, trying to encourage the formula to work. Shirley rummaged in her desk a moment and produced a condom package. Returning to me, she knelt once more. With a practiced motion, she opened the package and removed the prophylactic. Unceremoniously, she began to place the condom on my tool. The sensation inspired me and I felt my dick expand. Shirley noticed it as well, but was not sure what had happened. She stood up and took my hand. After leading me over to the bed, she stopped. Placing both hands in the waistband of her panties, she slid them off. I watched with wonder as the tufts of red hair came into view. Her pussy had bright pink inner folds that beckoned me into her steaming depths. The latex on my cock stretched as my dick extended even more. Shirley didn’t see as my cock surged to 12 inches. She lay down on the bed and silently invited me to follow. I clambered up after her and positioned myself between her thighs. Shirley’s eyes narrowed as she finally caught sight of my dick. It was clearly larger than when it had first left my pants. I, too, was slightly amazed at the growth; the extra formula I had ingested earlier was making a difference. I Positioned my cock at the entrance to her cunt as she began to speak. “It looks bigger now than-” I cut her off in midsentence as I inched into her. Shirley was very wet, so I slid into her easily. Her warmth enveloped me with ease, sucking me deeper. At last our pelvises made contact. Bracing my hands on either side of her, I drew back and made a second stroke. My cock was still growing and I went deeper this time. A third stroke and deeper still. Finally on the fourth stroke, I hit bottom. Surprise streaked across Shirley’s face. Apparently this was quite a rarity for her. “You are bigger than I thought,” she said with a lascivious grin. I continued my plunging and my dick kept growing. Shirley grunted with pleasure each time I slammed into her cervix. My insistent pounding at last gained me entrance, as the muscular orifice yielded to my pressure. Shirley’s eyes were filled with shock. “No one’s ever gone this deep before,” she whispered. “I can feel you inside me, filing me up.” Indeed, my dick was still expanding. I knew I was already much larger than I’d ever been. Shirley’s cunt had been initially quite roomy; now it felt like a second skin so tight was it stretched. Shirley was now moaning continuously. “Oh my God, oh my God, you’re splitting me apart!” Movement was becoming difficult in the confines of her cunt. The pleasure/pain overwhelmed Shirley at last and her entire body shook. Her powerful cunt muscles squeezed my cock and I felt her pussy juice flow out onto my balls. The vibrations did it for me, and I exploded deep inside her. My orgasm relieved some of the pressure as my cock constricted. I collapsed on top of Shirley and we both lay their breathing heavily. At last, Shirley calmed and opened her eyes. She stared at me uncomprehendingly for some time. “You hurt me,” she stated incredulously. I leaned back. “Sorry,” I mumbled apologetically. “No, it’s OK,” she said quickly. “I mean, it’s OK now, but at the end there, you were hurting me. I’ve never had any guy do that to me before. Even now I feel you deep inside of me and you’re still bigger than anything I’ve ever felt.” There was a bit of awe in her voice, touched with a little sadness. A tear rolled down her cheek. “Hey,” I said, “what’s wrong?” “It’s just that I never thought it’d happen. I never thought anything could fill me up. But you did that and more.” She paused. “Thanks.” She kissed me tenderly. Not knowing what to say, we held each other in silence. Shirley eventually fell asleep, so I quietly extricated myself from her embrace, got dressed, and left before her roommate returned. I was more than a little moved by Shirley’s emotional speech and I slept uneasily. The Formula Part 4 by TOABO I spoke to Jen that Friday. She assured me that Shirley would be OK, but that she needed time to adjust to this revelation. I reminded Jen of her debt and pinned her down to it despite her attempts to weasel out of it. She agreed to meet me at my room that evening and to come braless. At the designated time Jen arrived. She was wearing a pair of skin- tight jeans and a white cotton dress shirt. The shirt was noticeably shapeless, causing m to raise one eyebrow in query as I handed her a glass of dark green liquid. “Never satisfied, are you?” she said half-jokingly. “My tits are a good cup size larger than they used to be, but you’re just not content with a B cup. You’ve got to have a pair of D’s in your face before you’re happy.” To emphasize her point, she jumped up and down briefly. Her tits bounced merrily underneath the fabric in response; she was clearly not wearing a bra. “Good thing I borrowed this from Amanda. I’d hate to rip it.” I smiled and said nothing. That explained the looseness in the chest: the shirt was designed to contain 2 cup sizes more than she had. Jen sighed and drank up. “This tastes different from last time,” she remarked. I nodded. “I changed the formula a little,” I told her. “How come?” she asked. “You’ll see.” I replied. She frowned, but said no more on the subject. We chatted about the weather and school while we waited for the formula to kick in. After a few minutes, she broke off her sentence and said, “Woah! I can feel it. Here we go.” Beneath the fabric Jen’s tits began to swell. Her rounded cones began to fill in the empty space of the dress. Her nipples pressed insistently into the fabric. Jill gave her torso a shake, setting her grapefruit-sized breasts jiggling. The vibration was definitely more sizable than her previous gyrations. “There, that’s about right,” Jen said after a minute. Her breasts were now the size of grapefruits. Her shirt fit well now; it was no longer baggy, but didn’t seem overly clingy, either. Cleavage had formed in the gap where her shirt was slightly unbuttoned. Jen appeared quite beguiling. “Not quite,” I replied. Jen looked at me quizzically. but then realized what I meant. Her breasts had not leveled off as she expected. Instead, they continued to swell, drawing the fabric taut over her chest. “Oh,” she said with a bemused grin, “I see. You want DD’s this time.” She rolled her eyes skyward. “I swear. It’s never enough, is it?” Meanwhile, her breasts had continued to expand. Now comparable to cantaloupes, her tits filled up the shirt and then some. The hint of cleavage became a deep cleft. The shirt was definitely too tight now. Her breasts had now pulled it out of her pants, exposing her flat belly. Jen’s first look of concern came when the top button popped off her shirt. “Umm,” she pleaded, “Saul, is this about done?” My smirk widened into a grin, and Jen’s tits also expanded. A second and third button quickly followed, leaving a large expanse of Jen’s cleavage exposed. With an almost visible shudder, her breasts gave one last surge forward and popped off another button. “Now,” I said triumphantly, “it’s done.” Jen tugged on the shirt and managed to rip off the few remaining buttons in the process. Her breasts were the size of volleyballs. Fully inflated volleyballs, too, for their firm mass jiggled provocatively without sag. Her areolae were the diameter of soup bowls and centered on massive nipples that were easily as large as quarters. “Saul!” Jen hissed with more than a trace of menace. “What the fuck did you do!? You were supposed to make me a little bigger! Now I’m fucking huge! I look like a damn freak!” She glared at me angrily. “Hey,” I returned, “don’t get all huffy. You want my help, you pay the price. I just told you that I liked you with big breasts. I didn’t put a limit on how big I wanted to get them.” “Yeah, well, I wasn’t expecting this,” she grumbled. “I want you to make me smaller.” “No can do. You owe me, and this is the price. You don’t want to pay it, fine. But try explaining it to your friends. They may buy whatever line you fed them about being a B cup now, but there is no way in hell they’ll understand how your tits got this big overnight.” Jen was unhappy with this, but it was clear that she was forced to accept the situation. She tried to fold her arms across her chest indignantly, but failed miserably. Her massive breasts were too big and after a few quick attempts gave up. I sidled up to her and put a consoling hand on her arm. “Besides, Jen, you do look fantastic.” I raised my other hand up to a nipple and gave it a slight squeeze. She jumped slightly, but clearly enjoyed the touch. I bent my head to the other nipple and sucked on it gently. The protrusion hardened and expanded, reaching probably an inch and half into my mouth. I could feel Jen’s reserve melting away as I continued to suckle one tit while massaging the other. I switched after a minute and continued the process. After Jen’s moans became louder than whispers, I journey south. Jen’s tits dominated the top half of her torso, so I quickly passed her navel and reached the waistline of her jeans. With a few deft manipulations, I opened up her jeans and pulled them off her. A few seconds later her panties dropped to the floor as well. Jen’s pussy glistened slightly. I rubbed it gently with my right hand. Jen’s moans increased in intensity, especially when I flicked her clit. Just before she slipped into an orgasm, I drew back my hand. She moaned unhappily, but I quieted her and led her over to the bed. As she lay down, I disrobed. This came as a welcome relief to my cock; the sight of Jen with her even larger tits had sent my libido raging. It was already 10 inches long and still growing when I unsheathed it from my pants. I rubbed it a few times, enjoying the delicious sensation as I waited for it to quit expanding. Jen glanced up at me nervously, her eyes barely visible above her massive mammaries. “Saul,” she began. “that looks awful big. I’m not sure I can handle it.” My dick was now about 13 inches long and had a diameter close to 3 inches. “Oh, come one,” I chide her. “Shirley got this one in easy.” Jen’s eyes narrowed, but she said no more. I got on the bed and knelt in between her legs. I placed the head of my cock at the entrance to her pussy. Gingerly, I pushed inward. The going was incredibly tight. Despite being well-lubricated, her cunt struggled to accommodate my manhood. Jen inhaled sharply as I began to penetrate her. “Good Lord, Saul!” she shrieked. “That’s too damn big! Get it out!” “You didn’t mind when I was doing this to Shirley,” I replied coldly. I shoved a little more forcefully. Her eyes widened as my cock distended her cunt. “So what!” she yelped back. “This hurts, Saul! Stop it!” I ignored her and leaned forward yet again. My chest rested comfortably on her volleyball-sized tits and I gazed directly into her eyes. They were glazed over and tears were now streaming down her face. Jen was biting down fiercely on her lower lip as she tried to contain another shriek. “Do you think I enjoy hurting other people?” I asked. “Do you think I want to make other people unhappy? Well, I don’t, but because of you, I’ve done just that. Sure, you like to see your enemies get it, but you don’t seem to enjoy it now.” I collided with a cervix and drew a cry of pain from her. “Well, now you know what it’s like to be on the other side.” I began pounding into her. She wailed incoherently attempted to struggle, but I pinned her arms down with mine. My insistnt pounding eventually stuffed almost my fulle length into her. She screamed yet perversely shuddered into an orgasm as I slammed through her cervix. I climaxed soon after, and shot and shot deep inside of her. I pulled out and looked at her. Jen was sobbing quietly, curled up in a fetal position. It was made slightly awkward by the bulk of her breasts, but she didn’t appear to care. I spoke to her gently. “You see, Jen, maybe you were right. Maybe those girls did need a lesson. But so did you. You need to know that it’s not right to hurt other people for your own gain. Believe it or not, this hurt me, too. So from now on, I’m not going to be your enforcer anymore. You want to hurt others, then get somebody else to do your dirty work.” I went to the fridge and poured out a measure of the orange formula. I set the glass on the nightstand of the bed. Wordlessly, I grabbed a towel and headed into the bathroom. After my shower, I returned to find an empty glass, and no Jen.
