Scientific accident gives Brian the perfect penis. (sci-fi). By AnonymousPerv. Listen to the Podcast at Steamy Stories. Chapter 1. My name was Brian Johnson and that name was about to become notorious among the scientific community. I worked on a research team studying the effects of gamma radiation on living tissue and organisms. The research lab I work at is located forty feet underground, for a myriad of safety reasons, even if many thought it went overboard; unnecessarily cautious. But it’s meatheads like me that validate the needs of such safety protocols. One Saturday morning, while working alone, I accidentally opened a door to a sealed room, one we had purposefully contaminated earlier that week. It was getting cleaned through a new process involving some chemicals, and specific wave-length light pulses. Due to the new installation of this system, some of the original safety services and protocols had been disabled, which allowed me to gain access to the room, unfortunately. I got fully exposed as the alarms went wild. For the following month, my team repeatedly cleaned the facility and quarantined me to one room in the lab. I was on a high liquid diet and scrubbing myself down daily with chemical soaps and abrasive pads. Vitals were taken several times a day, along with blood work. Karen Langdon, the facility’s on-hand nurse practitioner, stopped by to visit me in my room near the end of the quarantine. I noticed she no longer was wearing a respirator, so the lab must have tested safe days ago. I was behind a plastic curtain which separated my half of the room to just a bathroom and bedding area. “You cost us a fortune, Mr. Johnson, you know that?” “I know,” I said. “I’m sorry.” Karen was a great medical nurse, every bit as knowledgeable as any general practitioner, probably better than most. She also happened to be a vested partner in the lab, and I think she had that on her mind every bit as much as my health. It was difficult to score research grants and jobs in our field, and a safe laboratory was critical in maintaining them. This mishap wouldn’t go unnoticed, and I felt very badly for having put my coworkers and the company under such stress. “Well, your vitals are all coming back fine. In fact, you’re in perfect shape. You’ve always been fine with your BMI and weight, but your pulse and blood pressure are better than ever. White blood cell count also better than it was last time you were here. I think you’re lucky.” “I guess so. Maybe that new cleaning system works better than expected,” I said, hoping. To be honest I was terrified. Often, the effects of radiation aren’t discovered until weeks or months after exposure, organisms developing tumors is common. The only thing that’s noticeable though is white blood cell count being abnormally high almost immediately. I was somewhat relieved to hear the news that mine was fine after a month in quarantine. “We’re going to let you out tomorrow,” said Karen. “Yeah, I figure I’ll leave this bag I’ve been living in, just to go out and get fired.” “That probably should happen, but it won’t,” said Karen. She knew something I didn’t. “You got exposed. We aren’t for a minute going to let you run wild. We have to keep an eye on you. So, for better or worse…” I dropped my head. “I know, I was careless. If I’m staying on, I’ll do my best to make it up to you, Karen.” Karen huffed a bit and then said, “Well, I guess that’s the best an attitude we both could have about it. So back to you. Are you positive you haven’t experienced anything strange? No panic attacks? No cold sweats? Heart palpitations? No physical changes? We need complete honesty to understand how we may need to address something.” I carefully thought about what she was asking. The truth was that ever since the incident, I did feel better than ever, and told the nurse as much. I explained that I always made a point to keep in shape, but I honestly felt like I was in peak condition now, even though I’d been cooped up in this room for the past month. Other than feeling good, I didn’t experience anything else. “Oh wait, I said. There is one thing,” I said. “I never brought this up before, because it’s kind of embarrassing, and well… I didn’t think it was a big deal. I mean, I’m not even sure if this incident has anything to do with it…” “Go on, Brian. Just tell me already.” Karen was behind the partition, but I could sense her impatience. “Okay, here it is,” I explained. “Normally, my penis hangs like the average guy’s, I guess. I may be just shy of seven inches fully hard, which I think is fine, but soft, the little guy usually just looks like a turtle tucked over my ball sack. There’s not much to it. Anyway, about a week after the incident I noticed it hanging rather low. Like… not half hard, but just hanging. About four or five inches long.” “Well, Brian, this does sound strange. You’re saying your penis got bigger?” “Well, when I get erections, I notice it appears to have more girth, but I don’t think it’s much longer. But soft, it just always hangs low now. Other than that, no change in anything. If that’s the worst of this, I’ll take it. Kinda nice, actually.” “And that’s it. Out of ALL the things that could have happened to you, you just happen to get… what?? A penis that you find more appealing?” “Well, I didn’t ask for it,” I said. “but I’m okay with that.” “Yeah, I’m sure you would be.” I heard the plastic barrier between us come unzipped as Karen entered. She had placed a filter over her nose and mouth, but was otherwise not geared up like usual. I guess they were about ready to let me mingle with them again, as I showed no trace amounts of radiation. I stood up facing her. “Alright, big guy, let’s see it.” Excuse me?“ I practically screamed. I didn’t expect a genital exam over it. My word was good enough. “You’re saying it’s ALWAYS this way? Half hard?” “It isn’t hard,” I explained. “It’s soft. Completely soft. When it gets hard it just gets stiffer and wider, really, not longer. It also rises, of course.” I felt weird being so blunt with her. “I don’t want to see it hard,” she said. “Just show me exactly what you mean. Please, drop the pants. It won’t take but a few seconds to get this over with.” The nurse was speaking pragmatically, as a professional. She seemed annoyed this was my only side effect. Having to inspect a penis from a guy she probably didn’t like very much was unlikely to be appealing to her. “You can take my word for it,” I said. “I believe you,” said Karen. “But due diligence. Let me see if I see anything unusual.” She snapped on a pair of rubber gloves. I sighed and finally dropped my pants, underwear with it. As usual, my cock hung down, easily six inches. It was a look I would be proud to sport at a nude beach, I thought to myself. Karen paused, just staring. I could tell she was somewhat impressed. Finally, she said, “And you’re like this all the time? Never soft like you used to be? I know what you mean. My ex-boyfriend had a nice looking penis when it was hard, but he was embarrassed of it when it would shrink away. You know we girls don’t really care.” She was almost blushing. I could barely believe Karen was being so intimate with me, as she didn’t stop looking at my hanging cock. Finally, she knelt down, getting closer, lowering her mask. “No decolorization or shading?” she asked, looking up at me. It was unusually erotic seeing her face only a foot or so away from my cock and I struggled to keep my thoughts straight. “I haven’t seen any problems, Miss Langdon. Like I said, it just hangs there all day, all the time, even after… well… you know.” “Really?” she asked, drawing her eyes back to it. She slowly lifted her left hand and lifted the head of my penis, inspecting the underside of it. “It doesn’t look like your vessels are stressed. It looks like a regular, healthy penis. Very healthy…” Her voice drifted a bit at the end. Karen must have only been six inches from it now and looking down at her so close caused an immediate reaction. Blood rushed through my shaft, pulsing my shaft up a couple notches. My penis thickened a touch and I wriggled back from the nurse a bit. “Oh, I am so sorry,” I said. “Is that normal?” she asked, looking up at me again. “Well, uh… no,” I said. “Just when… uh… it’s normal, I mean. I just had a reaction, is all.” “To what?” she asked, looking at me, deadpan, rising off the floor. “I’m sorry, Miss Karen. Your face was just so close to my penis. I had a normal reaction to it, just like if any woman was that close to it.” “Any woman?” “Well, uh… I don’t mean to offend.” Karen suddenly dropped to the floor again, putting her face close to my cock, but she continued to look right at me in the eye. “You’re saying ANY woman’s face being close to your penis makes you want to have an erection?” “Are you fucking kidding me?” I asked, both shocked and turned on, as her cheek was now no more than three inches from my shaft, yet she still looked at me, expecting answers. She had to have been teasing me, I thought, yet she looked so serious. “What I am asking, Mr. Johnson, is this: Would you have had the same response prior to being exposed to the radiation, if some girl’s face was next to your cock?” “Well, yes, I think so. When a woman is willing to get so close to it, it usually merits that it would be getting hard. I know this is a medical setting, but I just had a reaction is all. I am stating that I was sorry for having that reaction. I don’t think it is something we should be concerned about.” Finally, Karen took her eyes off me and turned them to my cock. Her nose was practically touching the head of it. I think I even felt her breathing on it. Of course, my reaction was stronger this time. With her being so blatantly sexual, my cock pulsed up in response and punched her in the chin. Karen Langdon, a woman I knew who really kind of despised me, just allowed my cock to touch her face. This only made my cock get harder and now it was rubbing against her upper cheek as it stiffened up. She slowly looked back up at me, but didn’t move her position, allowing my cock to scrape her skin the whole time. This time, as she looked up at me, her eyes looked more seductive than a medical professional’s should be. She was breathing a touch fast and said, “Brian, you have a beautiful cock. It’s so beautiful.” I was flattered. Even though I thought it looked great, her confirming it definitely stroked the ego. “Thank you,” I said. “You say your cock hangs like that even after you orgasm?” My eyes almost popped out of my head, but before I could answer, she grabbed my shaft and forced the head of my cock in her mouth, licking all over. She quickly picked up the pace and weaved my dick in her mouth as it became wetter and wetter. It was as if she made it her mission to extract every drop of cum I had, and I did just that unloading in her mouth. She swallowed loudly as she guzzled as much down as she could manage. With cum dripping off the edges of her lips, she dropped back, exhausted. “Oh my god,” she said. “I can’t believe I just did that. Why did I do that?” Her eyes were racing left and right. “I’m sorry?” I asked. “You started it. Are you okay? I don’t want you to regret anything. I enjoyed that. Thank you.” I could tell her heart was pounding fast and she looked at me with curled brows. “It was so weird. All I could think of when I saw your penis. I mean from the VERY moment I saw your penis. I wanted to suck it, Brian. I wanted your cum.” She glanced at my now hanging cock and looked up again frantically. “I can’t explain it. I needed it so badly. It doesn’t make any sense.” “Wait, you’re saying you had no control over it over wanting it, but you really didn’t want it?” “I don’t know,” she said, sighing. “I just… it’s like a voice inside me, combined with an insatiable thirst - one I have NEVER felt before, mind you - I just wanted to swallow your cum. I wasn’t even…” her voice trailed off and then she slowly looked up at me. “I always hated the taste of cum.” “Excuse me?” I asked. I wondered if I should pull my pants up, but I left it there, allowing her to witness that what I had claimed was true; that my cock did hang low even after an orgasm. Karen finally stood up, straightening her clothes a bit. “Look, we can’t tell anyone this or we would both lose our jobs, but Brian, that was weird. I don’t ever get horny like that. And that’s the thing. I wasn’t even horny. I just had this absolute need to swallow your cum.” “And you think this may have something to do with the incident?” “How else to explain it? I’m curious, do you have a girlfriend?” “Sadly, no.” “Any friends who are girls?” “Well, my sister who lives with me. She has friends that come over to the apartment all the time.” Karen picked up a clipboard. “I obviously cannot detail what happened today, but if you have the same reaction occur from other women, we need to know.” I cut her off. “Same reaction? What? You want me to go around flashing people?” Karen tilted her head and lifted an eyebrow, before coming to her senses. “Well, look, whenever. The thing is IF other women have a reaction like I did… the need to swallow your cum… please come report it. We could get it in your medical records sooner than later. I think it is important to do, but I don’t think we should report what just happened between us. Do you understand what I am saying?” I finally pulled my pants up and said, “Okay,” when I noticed something uniquely different about Karen. Her face was flush, in fact all of her skin was pink. I wondered if she was running a fever. More noticeable, were the pineapple-sized curves she was displaying under her nurse’s outfit. I’d always thought she was flat. “Karen?” I asked, looking at her chest intensely. It drew her eyes to them. “Oh my God,” she said. “No, no, no, no, no!” She quickly stripped out of the uniform. Her bra did nothing to keep her huge breasts from pouring over them. Nipples and cleavage were everywhere. She unsnapped the bra, sending it flying, exposing what must have been a pair of double dees. “Oh my, do you think this is from my cum?” I asked, bluntly. “What else?” she screamed, wide eyed. “Please tell me they stopped growing.” “I didn’t notice them until you got up. It must have been a very quick surge of growth, like right after you swallowed all that cum.” Her eyes drifted a bit as she whispered, “And it was so much cum…” “We’re going to have to tell the team,” I said. “This won’t go unnoticed.” I waved at her new set of knockers. I found them amazing, but it did give her the appearance of a bimbo. Karen looked at me, defeated. “Alright, so we tell them. All of it. The whole truth.” “I don’t see why you wanted to lie about it.” “Brian, look at me. I am going to be frank here.” “Okay.” “You’re a physically attractive man, but I am not, by any measure, attracted to you. I’m also kind of your superior here and I do have an occasional boyfriend. I’m sure you have had girlfriends, but you and I are NOT a match. I just don’t like your personality.” “Don’t hold anything back,” I said, referring to a Seinfeld joke she was probably unfamiliar with. “When I saw your penis, and remember, I was only examining it for medical purposes,” she stressed, “I didn’t get horny, but I had this incredible urge to swallow your semen. And now this.” She pointed at her tits. “I’m not sure anyone will believe us, but we’re going to need volunteers.” “Volunteers?” “Someone else to look at your penis.” Then Karen grabbed her purse, wiped her mouth with a nearby napkin and said as she was leaving, “I’ll be back in an hour with the rest of the team. Be ready.” It was Phil and Heath who came into my room first, not twenty minutes after Karen had left. “Holy shit, the cans on her!” cried Phillip. “It’s kind of fucked up, man,” said Heath. “But they do look pretty good.” “You saw them?” I asked. “Well, not naked, but yeah, we saw her new figure,” said Phillip. “Wait. You actually saw them?” “Uh, yeah, I did, I guess. They’re pretty spectacular.” I considered Phil and Heath work associates more than friends, but we could be honest to each other. They both barreled in laughter. Still, I could tell Heath was concerned. He’d been studying gamma radiation for years, and never had exposure to it proven beneficial for anyone. “I have to say, I am a bit worried now about these effects,” he said. “Supposedly, your penis changed shape and now, her breasts. Only after swallowing your semen. It sounds ridiculous, yet we saw the evidence from her.” “Don’t for a minute think I am going to let you see the evidence from me,” I quickly retorted. “She said the need for my sperm was insatiable. I don’t want men risking that same effect.” “Hmm, good point,” said Phillip. “But what woman is going to volunteer for this?” “Oh, I know who,” said Heath. “Janice. The loudmouth atheist we hired last year that works in C lab. Always a skeptic about everything.” “If someone from our team won’t volunteer, I suppose we could ask,” mumbled Phil, when the rest of the team finally did arrive. Karen, of course, but also Jennifer Hastings and Laura Pine, both married women in their 30s, and both shared a rather plain girl-next-door look. “So as this information goes up the chain, I would appreciate everyone understanding that what occurred today was NOT meant to break work ethics and rules.” Karen was updating everyone on the events that occurred, while trying to excuse us of any wrongdoing. She continued, “We admit we violated company policies, but please understand it was against our will.” “Who forced you?” asked Jennifer. Karen did her best to explain that the compulsion she experienced was one she had no control over, when Jennifer interrupted and pointed at me. “Brian had control, though, didn’t he?” I suppose I did, only I just now realized it. I willfully engaged in sex while Karen didn’t. I tried to explain myself, but it all looked pretty bad for me. First, I caused this mess and cost the company a fortune in cleanup costs, and then I willfully engaged in sexual acts that breached our code of conduct. I was an idiot, who appeared to not even want to have a job. “You don’t understand,” I babbled. “One just can’t NOT do that when offered. Wait, I mean, it was a desire for me, too. I mean… insatiable? I guess we could debate that, but…” Then it hit me. the only way I could defend myself is to cross my fingers and explain it through a demonstration. I immediately dropped my pants, displaying my freshly washed penis in front of everyone. Immediately, the room went silent. “Oh,” said Jennifer, meekly, after a few seconds had passed. “I think I understand what you mean,” looking over at Karen. “I know! Isn’t it crazy? You just want to… right?” “Want to what, though?” asked Laura, stepping closer to my penis. Phil and Heath looked on at the girls. The two men had also glanced at my junk hanging there, but thankfully it didn’t seem to drive them to strange compulsions like it did with the ladies in the room. “Did it get hard for you instantly?” asked Jennifer to Karen, as she too, stepped closer to me, and they all were getting down on their knees. Of course, I reacted like any healthy man would and my cock stiffened up like a rocket. Instantly, Jennifer was on it, sucking hard on the head of my cock. Laura grabbed my shaft with her right hand as she stroked it towards Jennifer’s locked lips. Karen licked her tongue, looking on closely. She then looked at all the men in the room, including me. “I will explain what’s happening here while these two work Brian’s cock. We all apparently are experiencing a need to drink his semen. Something that should be noted is I am not aroused.” “Me, neither,” said Jennifer, pausing for a breath before opening her mouth wider, allowing me to slide it in further. “That really is strange,” said Phil to Heath. “How long will it take for you to cum, Brian? Will you be able to provide enough semen for all three?” “All three?” I gasped, looking down at the scene. “Shouldn’t we get them off me?” Jennifer’s luscious lips over the head of my cock made my shaft pulse rapidly in Laura’s stroking hands. Laura picked up the pace to pump my hot goo into Jennifer and I couldn’t help but unload for a second time today into her eager mouth. Jennifer made no bones about trying to swallow every drop. It was like she had been without water for days. “Me, next,” exclaimed Laura, looking up at me and shoving Jennifer aside. No longer content with stroking my dick into someone else’s face, she wanted a go at it. Phil stepped forward. “Brian, do you think you’re also experiencing more sexual virility and endurance?” “I am enjoying this. I think I would have enjoyed this even before the incident. I don’t know if I am performing any better or worse, but I will say I feel like I could go maybe once more. But again, don’t you all think we should stop?” “Are you fucking crazy?” shouted Laura. “Not until I get some!” The crowd watched on until moments later, she too was gasping for air as she swallowed my incoming load. It was what happened next that surprised us most. Just as I was finishing up cumming in Laura’s mouth, Jennifer cried out. “Oh no! no!!” Jennifer already had C cup tits, I was sure. She was the largest in the group before all this, but now her tits were practically bursting through her blouse. In fact, they were. Two buttons went flying as her tits spilled out. Her breasts grew into such a freakishly large size so quickly, it looked almost comical. Laura looked around panicking. “That’s going to happen to me, too? Like in just a few minutes?” “It appears so,” said Karen. “I swallowed his cum, then Jennifer. We both experienced the same shocking result.” “Do you think they will eventually go back to normal?” In her voice, we could tell Laura was panicking. “Lionel hates big tits.” Lionel was her husband whom she always raved about. I felt lips on my cock again and looked down. Karen was doing it again. “Karen!” I screamed. “Stop. Your tits!” She looked up for a moment. “You don’t understand. This is not about me wanting bigger tits. I just need to swallow your cum.” “Isn’t it so weird?” gasped Laura eyeing everyone in the room. “I had that same strange compulsion to swallow.” “But Karen, your tits will get even bigger,” I pleaded. “How do we know that?” she asked. “It might only happen the first time. The one time. We don’t know.” “You don’t want to find out, do you?” “I just want to swallow your cum. Now are you going to let me or not?” Before I answered, she was going down on me, forcing her tongue on my shaft. It was a delightful pleasure as once again, I felt myself get fully hard, eager to deliver yet another load. Heath looked at me, then Phillip. “Well, I think we got a few years of research ahead of us, whether we wanted it or not.” “We won’t have to worry about funding,” said Phil, flatly, as I finally erupted into Karen’s mouth for the second time today. She let nothing escape, guzzling it all down. “That was even more than last time!” she exclaimed. “Why won’t we have to worry about funding?” asked Heath. “What’s the joke? What am I missing?” “Take a look at Laura. Instant natural breast enhancement? You know how much women would pay for that?” Heath turned his attention to Laura now, amazed to see what must have been D cup breasts straining her blouse. “Lionel is going to be so mad at me,” she cried, as she peeked down the top of her blouse. “Can we see them?” asked Heath. “Are they all gaining the same amount of mass in size, I wonder.” All the girls looked at each other, before sighing and giving in. The tops and bras came off. After careful examination and some information from the girls, Phil, the math expert, estimated that each occurrence added about 26 ounces of flash. That’s when we saw it. Without any cry of pain or discomfort from Karen, her breasts morphed before our eyes. Within a span of eight or ten seconds expanding even bigger, leaving her with breasts bigger than my head and nipples that would make bovines envious. Karen sighed heavily. “It’s so weird. Once I swallowed, I was fine. No longer having some irrational desire in me. It’s like a heroin addiction. Once someone is so bad off, they need the drug just to feel normal.” Karen looked over at me. “Please, Brian, under no circumstances, show me that penis again. I’ll be handicapped if my tits get any bigger than this.” I quickly picked myself up, got dressed and said, “We gotta fix this, or I won’t ever be able to have a relationship. It’s a good thing my girlfriend and I recently broke it off, but no, I cannot live like this.” “He’s right,” said Heath. “Any girlfriend couldn’t risk seeing his penis more than once or twice, based on everything we’re seeing. This will be difficult to figure out.” “We’ll figure it out,” said Phillip. “We’ll start tomorrow. Brian, you can go home like you were scheduled. Just keep it in your pants, okay?” “Okay,” I said. I was eager to get home. My sister, Penny, and I weren’t bosom buddy close, but we did enjoy our company now and then, and I had been secluded for far too long. It was a welcome sight when later that night, Penny and I got to share a pizza together at the dinner table, rather than in front of the TV. I explained in detail the reasons I had to be quarantined at the lab for so long, leaving out the part about my penis. “So we want to ensure I have absolutely zero chance of spreading any radiation, as well as making sure I’m healthy.” “And you are? Healthy?” Penny was concerned. “So far as they can tell, no ill effects. They’ve insisted they will monitor me closely.” Again, I wasn’t keen on sharing the fact that I had been sucked off four times today by three different women. Except I keep forgetting that I am an idiot. An utterly thoughtless, despicable idiot. It was bad enough I created all that damage and drama at work and that I also willfully never stopped any of the girls from sucking my cock, as any decent guy would at least try to do. After all, this was happening technically against their will… but this time, what I did was the worst of the worst, and I cussed myself again and again for it later. After Penny and I visited for a while, we finally went off to bed for the night. I have to sleep on the pullout bed in the living room. For a couch bed, it’s pretty comfortable. Our habits are always that when Penny goes off to her room, usually around 11 or so, I change into my pajamas and eventually get to bed by midnight. I’m pretty quiet and Penny rarely, if ever, leaves her bedroom until morning. Being my first night truly alone, after Penny went off to bed, I undressed as usual and pulled the bed out, but I didn’t bother putting on my pajama flannels. I turned the TV on, setting it to a low volume as usual, and instead of curling up under the blankets, I stood in front of the vertical mirror next to our fireplace. I was admiring the way my penis was hanging, thinking about how cool it was to at least having gotten something from good from this experience. I then bounced up and down a couple times, playing helicopter with my cock, when Penny burst into the living room. “Hey Brian, I just wanted to say I might have enjoyed the vacation from you, but it was getting lonely…” She stopped in her tracks, as she just noticed me naked. I leapt over to the couch to grab a pillow, but she stepped forward instantly as I did that. “Oh, wait,” she said. I ignored her and grabbed the pillow, anyway, covering, yet Penny came forward even more. “Brian, I uh…” her eyes darted up and down from me to my crotch. “I, uh, didn’t expect to see you this way.” “Sorry, sis. I was just changing.” “It uh, looked like you were playing a little.” She stepped forward even more and I almost backed up, cautious. “Look, Brian, I need to borrow a pillow. Can I?” Without giving me a chance to think, she snatched the pillow from me and her eyes bulged wide. “Oh my goodness!” she cried. She looked up at me, panicking almost. “Brian, this is going to be weird, but I… I… Can I? May I? I need to do something.” Before I could answer, she was swallowing my cock. I was hard in no time, yet confused by the ordeal. I had to tell her what was about to happen. “Penny, you can’t do this. It isn’t right.” She pulled me out of her mouth, stopping a moment. “I know, right? It’s definitely not right. I can’t explain it though.” She grabbed it with a hand and looked up at me. “I uh… this is embarrassing…” “I know,” I said. “You need to swallow my cum.” “Yes! That’s it exactly!” She immediately went back to work to make that happen, but I objected. “Penny, listen to me. You cannot swallow my cum. If you do, your tits will grow bigger. Like instantly, bigger.” “What?” she screamed, pulling off again. “That’s ridiculous. I just need to… I don’t know… scratch this itch, is all.” “That’s the thing, Penny. If you do, I promise you. I have seen it. Your tits will grow bigger.” Penny looked at my cock and back at me. “Well, what if I just taste it a little?” “Penny…” But my objection went ignored. In seconds, she was back to forcefully sucking on my shaft while sending jolts of pleasure through my body. She tickled my balls as she sucked, eager to get everything delivered into her mouth. “Penny! P… Pah… Penny! I am going to cum. You can’t swallow.” I could hear her gagging and protesting the need to get me off. I even tried pulling my cock away, desperate to get her mouth off it. She finally let go and opened her mouth wide. “But Brian! I need to taste it. Don’t let me not at least taste it!” I was already unloading and jolts of cum went spraying directly into her mouth as she was begging for it. Its presence sent her eyes wide and put a glow in her face. She opened wider and thrust herself over my cock, ensuring she got the second and third shots filling her mouth. I couldn’t help myself. All I could think was how grateful I was that my sister had small tits. At least I wouldn’t turn her into a freak. She’d just have a different shape. “I can’t believe I just did that,” said Penny, sitting there, looking defeated, with my cock hanging in front of her. “That’s what the nurse said,” I sighed, finally beginning to feel exhausted from all of the day’s activities. “Why did that happen?” asked Penny, looking at me. “We haven’t figured it out,” I said. “But I meant what I said. Your tits are going to get bigger. You have to be sure not to ever see me naked.” “Well, don’t go walking around the house naked! But what do you mean? Bigger?” “Do you trust me, Penny?” “Uh, I just sucked you off and I don’t understand why. So no, I’m not feeling sure about trust right now.” “You know I wouldn’t make you do that on purpose.” “I know, brother, but I don’t understand what happened.” “Look, in about two minutes you are going to experience something. That is, if you work like the others do.” “You mean it? Really? Bigger tits?” “Yeah, I mean it. You might want to get out of that bra.” Penny paused, looking at me skeptically. You’re not just telling me this so you can look at my tits. You know I remember you trying to spy on me naked once, right?“ “Come on, I was young and a dweeb,” I protested. “Penny, I’m not like that.” “Fine,” she said, removing her t-shirt and bra. Her pert breasts were surprisingly sexy to me. I’d never seen them before, as we were both rather modest growing up. Her nipples were larger than I expected for being on such breasts. Her mannerisms made her look more mature and sexier than her petite figure would normally achieve. “Two minutes?” “Less, now,” I said. “The girls didn’t experience any unpleasant feeling, either. I noticed their skin looked flush for a while.” And as I spoke, I saw that happening. Penny’s face was turning a deep pink. “Do you feel alright?” I asked. “Yes. Nothing strange… other than standing naked in front of you after having sucked you off. Yes, I’m alright!” She was being sarcastic, but the attitude changed soon after, as within an eight-second window she went from her a-cup size to what I would easily guess as a c-cup. “Jesus Christ,” I said. “I will never get used to that.” “Brian, this is amazing!” She paused. “Gross, but amazing!” I laughed, while pulling up my pants. “Well, glad you’re happy about it.” “I mean, come on, man. A girl’s appearance. I always did want bigger boobs. Weird way to get it and you have some explaining to do. This has happened before?” “Yes, today,” I explained. Penny and I both continued to stare at her new, heavy breasts while I described the effects I had over women seeing my penis and their insatiable desire to swallow my cum. “Brian, I hate giving head. I hate the idea of my boyfriend cumming in my mouth, yet I can’t help but say I had to have it when I saw you. It was… it’s… it’s indescribable, really. No compulsion I have ever had felt quite like that.” “That’s what they all said.” I very much enjoyed looking at Penny’s tits and must have made it too obvious. She finally began using her arms to cover her nipples. “I’m going back to bed. Thanks… I guess?” Penny wandered back and I plopped in my bed. I was very much worried how much a problem this would be, until… The following day. When we went back to work, we were surprised to discover that all the girls started slowly going back to their original size. It appeared to hold for about a twenty-hour window and then slowly go back to normal. Unlike the way the breasts grew, which was immediately, as they went back to their original shapes, it took over an hour. Phil said, “It almost works like an instant release pill. I wonder… could that be put in pill form?” He looked at everyone in the room. Phil was seeing dollar signs, I think. Knowing this would affect Penny soon, I called her to explain what was happening. “So you mean in a few hours, these tits will go back to normal?” she asked. “That’s right. You can breathe easy.” “Brian, I actually liked them, remember?” “Oh right,” I said. I was just relieved no one was ever at risk of getting permanent mammoth sized boobs from me, and I hadn’t been thinking about some of the actual positive results others may have seen in it. After I hung up the phone, I went back to the team. “Well, I’m just so glad I didn’t permanently inconvenience anyone.” Laura and Jennifer scoffed at me and Karen huffed, turning away. I figured they would all be happy to be back to normal, especially Laura who claimed her husband hated big tits. “Is everyone okay?” I asked. I barely said the words when Karen butted in loudly. “Fuck you, asshole! YOU get all the benefits! A cock that looks perfect in every way, the insatiable desire it embeds in women to suck it… and all we get is a TEMPORARY benefit. I hardly think that’s fair.” I was stunned. When Karen left yesterday afternoon, her tits were so big she could barely drive home. Why would she want that? She continued ranting. “And all you have to do. All you have to do is show your dick and there we go again, begging to be your cumdumpster. Think about it, Brad. This is pretty fucked up in your favor.” I looked down at the floor and then at Phil and Heath who were both shaking their heads. “You’re mad at me, aren’t you?” I asked, looking at Heath. “Actually, Brian, no. I find this anomaly fascinating.” He looked at Karen. “Karen, how badly do you need to suck Brian’s cock right now?” “What?” she screamed. “Not one bit! No!” “Okay, I am just making sure he doesn’t have that effect on you unless his dick is out.” “That’s how it appears,” she said flatly, then looking at me. “Don’t get any ideas.” Phil spoke up. “I thought you liked having bigger tits. Wouldn’t you be willing to suck him off to get them again?” Karen scoffed. “Not if it’s only going to last a day. Sorry, Brian, I don’t like you that much.” “As we have established,” I said, taking some glee in the knowledge she had already sucked me off twice, regardless. “What if…,” said Phil, pausing. “You needed more than one treatment for the effects to be permanent, like how some medicines for treating depression work. You take them until your body adjusts and then you have no need to take them anymore.” “Wait, are you suggesting we keep swallowing his cum?” asked Laura, looking at Phillip. He shrugged. “If someone were willing to try some different methods and schedules of treatment, we could measure any changes or progress in how long the effects last, etcetera.” “I’ll do it.” I thought it would be Jennifer to say that, but surprisingly it came from Laura. I objected a bit, “I thought you said your husband didn’t like…” “Never mind what I said. Just do it. I mean it. I’ll suck you off ten times a day if I have to. I want the effects to be permanent.” Phil and Heath looked at each other astonished. Laura was the good Christian girl, with the happy marriage, or so everyone thought, when she finally blurted out. “Okay, I saw him! Yesterday, when I was driving home, he called and said he had to stay late at the office. I know he doesn’t like big tits, but I thought the change in my shape was something that warranted being addressed sooner than later, so I drove to his office. I didn’t tell him I was coming.” The entire room was silent as she continued her story. “It was after six by the time I got there and the building was empty, but I saw a light coming from his office. I walked in and there he was, banging his new secretary on his desk! She had tits bigger than mine. Bigger than the ones I had yesterday! He’s lied to me all this time!” “And you think bigger tits will solve the problem?” asked Heath. “I’m afraid the issue runs deeper than that, my dear.” “I don’t care, just do it. Show me your dick.” Laura ran over to me. Phil raised his hand. “Everyone, let’s leave the room to them. Brian, with your permission.” He closed the door behind them as Laura, teary eyed, went down to her knees. She was sobbing quietly. “I don’t even like sucking cock,” she huffed. “But I need this.” “Would you like me to fuck you first?” I asked. I was loving all this cock sucking, but I was craving pussy. “Get back at your husband, huh?” She looked up at me. “Would you?” “Do you think it’s a good idea?” “No, but I don’t care right now. Go ahead. Fuck me. Fuck him! I mean it. You can use my pussy. But please, I do want bigger tits. Let me swallow you when you finish.” “Don’t worry,” I said. “We’ll get there. You get naked and close your eyes. I don’t want you seeing my dick until I am done making you cum.” Laura, now completely nude, bent over and turned around. “We’ve got work to do,” she said.
