Hi all, this is my first story - please let me know if you have any feedback, or if you want to see more.
I feel like I’d been staring at the monitor for hours. I traced out the equation on the screen with my pencil, then tapped the pencil’s eraser against my nose. Everything looked correct. I’d tested the formula on mice, run it through various computer simulations, and mapped out the worst-case scenario, over and over, for nearly a year. Since I was 15, I’d worked on my dream project, certain it would give me everything I wanted.
“Ted! Are you coming to bed?”, Jenna asked.
Jenna already knew the answer, but this was part of our nightly routine. She got in bed at 11, called for me at 11:30, I said “Five more minutes!”, and I worked on the computer until 2. But this time, I was done. I was sure of it. She wasn’t exactly sure what I was working on, but thought it was for work. Otherwise, why would I have three computers, two printers, a 3-D printer, and on and on in my office? It was most certainly not for work, of course. When I was 15, I’d gotten hooked on muscles. Having them, that is. Being huge. Going to the gym was boring, slow, and incredibly unsatisfying. But, ah, if there was a way to chemically force my body to grow muscle, then that would be the most efficient route. I didn’t really think stuff like Dr. Jekyll and Mr. Hyde was real, but maybe the human body just needed the instructions to induce actual drastic physical change. All you needed was software and something to power it. So I taught myself biology, chemistry, anatomy, biochemistry, DNA, physics, programming, etc. etc. – and actually netted myself a doctorate in the process. Now 27, I’d dedicated 12 years to this fantasy, but there was a nice side product – I might actually have a working formula. A formula produced a solution that jump-started a chemical process in the body that built muscle consistently and steadily, over time. With a daily dose every morning, I’d be a mass of muscle in just a few months. Computer simulations suggested it would work, but the mouse trials that produced big, aggressive, strong mice – that was really something. I had started shopping for speedos and man-thongs online, and found myself masturbating or forcing myself on Jenna constantly. She didn’t understand why I wanted to fuck at 2am, but I wouldn’t take no for an answer. I hit the switch on my computer to start synthesizing a dose for the morning, and headed to bed. I pulled the covers back, and climbed on top of Jenna.
“Ted, come on - I have a big day tomorrow.”
“I‘m finishing a big night right now.”
She sighed and let me peel her pajama pants off. I pulled her panties aside, and pushed right in with no warning, pumping away. In anticipation of having the muscle to totally dominate her in a few months, I was a little rougher than usual, squeezing her shoulders, and her ass.
“Ow! What is with you? I gave you some ass.”
“Just loving my little Jenna.” She looked annoyed, but played along.
The next morning, I got up an hour early just to down my dose. I had a little coffee machine-type device I’d rigged up years ago that could create any type of liquid concoction you might want from a variety of ingredients, liquid, powder, or what have you. I even had orange Gatorade added for flavor. I quickly picked up the dose – a small quarter cup of translucent green fluid – and swallowed it. It didn’t really have much of a taste – maybe a faint copper flavor. I immediately got an erection, but I chalked that up to excitement. For the next week, I took my morning dose, and found myself jerking off non-stop, and I even began jumping on Jenna as she came in the door. I peeled off her clothes at the front door and pounded her on the couch. During the week, I weighed myself, measured my body parts, and did visual checks, even taking nude selfies. I should have seen minor muscle growth evenly across my body, including penis growth (yes, I added that in). I’m a pretty average guy – 5’9, slender, but no real muscle tone. Dick … average? Around 6 inches or so, but I was going for a pussy-splitter. Something in the neighborhood of ten inches. I wanted to hit …. maybe 6’4, 6’5? And the body needed to be massive. Wide shoulders, big pecs, the whole thing. I had a computer layout of my body measurements and how to chart them until they hit world-class bodybuilder dimensions. But after doing measurements on day 7, I saw no changes.
After 7 whole days, I saw no difference whatsoever. Nada. I didn’t get discouraged; after all, some medications needed time to build up in your system before having an effect. Okay, maybe I was a little discouraged. No more constant hard-ons. Jenna was fine with this; she had started to get pissed whenever I started grabbing her ass or pulling at her clothes.
“Oh, I get a night off? Great. Maybe you should lay off the porn. Or look at it more. The opposite of what you’ve been doing.” I didn’t even bother to respond – I was curious why I hadn’t seen any gains.
The next morning, I took my dose downstairs, and dumped it into a glass of orange juice. I started to butter an English muffin, and reached for the glass, only to feel someone’s pajama pants.
I turned, and she was finishing my orange juice.
“Sorry, chief. That was the last of the OJ, and you were supposed to buy more.” I stared, slack-jawed. “You know you were on grocery duty. Don’t give me that look.”
I slammed down my knife. “God DAMMIT! That was fucking mine! What the fuck-“
She was taken aback, unsure why I was spazzing out over orange juice. I cut myself off mid-swear and marched upstairs. I checked to see how long it would take to synthesize another dose – 4 hours. I heard Jenna slam the front door as I hit the start button.
When I got home that evening, I went straight to my office and gulped down the dose. Then I started making dinner. Jenna came in as I was boiling noodles.
“So… what was this morning all about?”, she asked.
“I was being a jerk and I have no excuse so I’m cooking dinner and hoping you’ll forgive me for orange juice,” I replied.
“Are you feeling okay? You were all despondent last night. No computer work, no begging for sex, nothing. A girl starts to wonder if she still has her charms,” Jenna looked at me quizzically.
“Oh, just stressed out about a timeline for work, and I was a giant baby about it to you.” I wasn’t being honest, but I couldn’t tell her the truth.
The more I thought about it – I wondered… should I tell her? She drank a potentially body-altering chemical that could- no, she had one dose, and her body will dump it. If nothing happened to me in a week, nothing is going to happen to her. We watched a movie and snuggled on the couch before going to bed. The next morning, we both woke up together slightly early. Jenna felt around for my cock, and started stroking – that wasn’t like her. She was very much about her routine in the morning. Then again, we were up early.
“Hey Ted. How’s little Ted? I mean, how’s Big Ted? Or Medium Ted? Does he even have a name?” Jenna reached inside my boxers.
“Good morning to you too,” I offered.
I put my hand under her shirt to touch her stomach. Jenna had a very average girl-next-door body, with no real muscle to speak of – but my hand was touching some… muscle? She was usually so soft, but this was firm. Jenna pulled her shirt off and mounted me, and we had a quick morning session before getting dressed. She certainly looked different. Just a little. Could the formula have affected her? As I got dressed, I looked at the morning’s dose. I took it downstairs, and dumped it into a glass of orange juice. Jenna came down right behind me.
“Here, kiddo – have some juice,” I said, holding out my glass.
“After yesterday? Nuh uh, I’ll just walk around outside with my mouth open until it rains,” she started to reach for the fridge.
I put my hand on her shoulder. “As the man who was wrong and a giant man-baby and should apologize to his beautiful girlfriend much more than he does, I beg you to drink this peace offering.” I held the glass up like a fancy bauble to Indiana Jones.
Jenna smiled and took the glass. I figured I could rig up another dose later that day; I needed to see if Jenna was actually benefitting from the formula. Over the next week, I kept up the orange juice gag – and it became a part of her routine. I had my dose in the afternoon, she in the morning. And, god damn it – she was growing. I noticed that her softness was giving way to more firmness, everywhere. Her shoulders seemed wider. Her hands seemed a little bigger. Her thighs, thicker. Her legs had always been fairly pencil-y, but she was starting to show tiny calves. Calves. Over the next 2 weeks, she grew – slowly, but surely, she was getting bigger. I, on the other hand, was exactly the same. I tried mixing my dosage with orange juice, I tried eating what Jenna ate, sleeping when she slept, everything she did.
I went back and checked the equations, reviewed my math, reviewed the science – I was back to staying up until 2am. My work was just fine. So what was the fucking problem? Later that night, I was jolted awake.
I rubbed my eyes. Jenna had been patting my face harder and harder until I woke up. “Huh?”
I made eye contact with Jenna. She turned on the lights, pulled the sheets back, and climbed on top of me. “Jenna, it’s…. what time is it?”
She started to pull my boxers down, but I put my hand on her wrist to stop her. She didn’t even make eye contact as she swatted my hand away. We wrestled back and forth until she just reached through my fly and started beating me off. My cock responded to the attention, but I was getting mad. It had been… a month? I’d been trying this muscle experiment for a month after doing over a decade of research, and I had nothing to show for it. My girlfriend, all 5’5” slender build of her, was getting bigger. Growing muscle. Getting stronger. Getting more aggressive. Hornier. More dominant. Well, that was stopping. I tried to push her off, which only succeeded in pissing her off.
“So when you want some ass, the store is always open. When I’m in the mood, the shop is closed? That’s how it is?” She was definitely pissed.
“Jenna, I need sleep-“ I was not in the mood.
I was about to get her off of me when she slapped me. It wasn’t hard, but enough to catch me off-guard. I expected her to storm off and sleep downstairs – but instead, she grabbed my cock, and inserted it into herself, and started going to town. Before I could start to protest, she already had my wrists held down, with her knees at my hips, pinning me in place. She leaned down and bit my lip to keep me from talking.
The next morning was a Saturday, so I expected to sleep in.
I found myself, however, being nudged by Jenna. “Ted, go get my orange juice. And breakfast.”
Before I could argue, she reached into my boxers, and started fondling my dick. I was awake now. I took the morning dose down with me, and dumped it into a glass of orange juice as I got some English muffins ready. Wait, what was I doing? I just told myself I was cutting her off. I stared at the glass of juice.
“Ted! What’s the ETA on that juice?”
I supposed, at this point, I should keep the trial going, and see how she progresses. Right? Plus, the sex was great, and I had time to see what was wrong with my formula. I took the food and drink upstairs.
She downed them right away. “Oh, that’s it? I was thinking maybe some fruit, too.” She did the puppy dog eyes.
“Yeah, maybe – I’d have to go out.”
“Great. I need to eat better for the next few days for my physical next week.” She started to adjust her pajama shirt. “Then again, I’ve been feeling great lately, and my yoga class on Wednesday is really paying off. I’m seeing some muscles pop up.”
Physical? What physical? That might be a problem – she might have elevated testosterone levels. Was this for work? Hmmm.
Interestingly enough, this is the first time she’d acknowledged her body’s changes.
“What physical?” I asked.
“Oh, that once-a-year thing at work where they do blood pressure and bloodwork to raise awareness about … I’m not sure. But everyone skips junk food for a week. Why?” She didn’t make eye contact – she was too busy rubbing her hand back and forth across her newly-appeared ab muscles, which she just seemed to have discovered.
I shrugged as I realized I was getting hard watching her explore her new body.
“How ‘bout that fruit, champ?”
As I browsed the Safeway for … fruit, I thought over the formula in my head. Maybe Jenna was exposed to something at work. Maybe something in my genes was blocking the chemical reaction. I wasn’t on medication, and neither was Jenna, except birth control. But now, this physical, that was a problem. Could it get her fired? Maybe I should tell her. Up until now, this whole thing had been… unethical, at best. What had I done?
I came in with two big paper bags full of enough fruit to fill a grocery cart. Jenna was waiting in the kitchen, and started eating the bananas.
“Jenna, can we talk?”
“Sure. Is this about more fruit in the car?”
“No. This is about your physical.”
She didn’t make eye contact. She’d fit the entire banana in her mouth, and was rummaging through the bag until she got a peach.
“You may have something in your system that might come back on a blood test,” I started.
“I don’t think your jizz will come back on a blood test,” she said, pulling an apple out of the bag.
“No, not that. A few weeks ago, you drank my orange juice, and I got upset… because I’d put some medication in there for me,” I was looking at the ground.
“Well, if it was a one-time thing, I’m sure it’s out of my system, but now I know why you blew up over juice, so hey,” she nodded to the side.
“It wasn’t medicine. It was an experimental… drug. For me. To build muscle automatically. And I’d been taking it, and still am, with no success. But you grew muscle right away, and you’ve been on it for the last month. And that’s why you have abs and muscle, and why your pants don’t really fit. And why you’re hornier.” I looked up.
She was looking right at me with a blank stare. She put the finished apple on the counter.
“Excuse me?” she asked.
I shrugged. “It was wrong, and I’m sorry, but … I had to see if it wor-“
I never finished the sentence. Jenna had balled up her hand into a fist, and driven it into my cheek. I went to the floor.
“What the… FUCK…. is the matter with you? I could be eating poison. I could have cancer. What the … shit?!” She ran upstairs.
I could tell she was pulling a suitcase out of the closet and stuffing it. She came down the stairs a few minutes later, with a half-zipped rolling suitcase, a shirt poking out. I tried to block her path to the front door, and it became another fight like last night. Again, I thought I had my foot down firm, and was sure I wasn’t budging; we pushed back and forth until she shoved me aside. I tried to grab her arm, but she just swung wildly with her fists, landing a few punches on my shoulder and back. I tried to pick her up, when I felt my feet leave the floor – she had picked me up! She flung me to the side, and stormed out the door. That went about as badly as it could have, I guessed. I cleaned up the furniture we’d knocked over, and put a bag of frozen peas on my cheek. I couldn’t tell if it was going to bruise. I tried calling Jenna’s phone. Straight to voicemail. I spent the rest of the day sitting on the couch, staring at the TV, which I didn’t bother to turn on. I still took my afternoon dose. I went to bed at 11, and looked out the window for any sign of Jenna. I thought about driving around to friends’ houses, hotels, or who knows what, but I was pretty sure she didn’t want to see me.
I was jolted awake by someone rubbing my shoulder.
“Huh? I turned on the light by the bed. It was Jenna.
“I understand why you did it.” She took off her clothes except for her underwear and bra, and climbed into bed, spooning me as the big spoon.
I had no idea what to say.
An hour later, she woke me up again by grabbing my cock, lightly slapping my cheek.
“Let’s go, mama needs.”
“Huh?” I was so out of it and confused. She didn’t wait for an answer. She held one hand on my chest while she worked my cock with the other. As soon as I was hard (it didn’t take long), she started pounding away.
“I want you to keep giving me the drug.”
"But I thought you-“ she held her hand over my mouth.
Over the next two weeks, I kept up the drug for both of us, with only her seeing results. She started to show real muscle definition, especially in her quads and back. Her energy levels kept going up – she started jogging in the evening, just to burn off her excess energy. We had sex as soon as she got back, and again in the middle of the night, every night. She had me order a cock sheath online just as a back-up in case I was ever too tired to fuck. She also had me get Viagra, dildos, and so on and so on. The evening sex was very much a relationship-type couple fuck session – but the middle of the night was not. As time went on, she got bigger and stronger, and the sex got rougher and more painful. Every morning I found new bruises in the mirror, mostly on my shoulders and waist. I had some big ones on my ass where she squeezed me too hard. Once, she bit my tongue too hard – as I started to make a noise, she clamped her mouth over mine, and squeezed my shoulder like her hand was a pincer, giving me worse pain somewhere else as a distraction. The night sex was clearly all Jenna taking control. I was, at this point, a dildo named Ted. I enjoyed it, except for the bruises and stuff in the morning. We had reached the point where I could no longer physically stop Jenna from doing what she wanted; fighting her just meant more bruises, possibly on the face. It was just easier to give in. In the meantime, I hadn’t discovered why the formula wasn’t working for me. I was ready to start testing the coffee or something at Jenna’s office. As for her physical, Jenna simply called out sick that day. Jenna was, under her clothes, ripped. Her work clothes pretty much hid everything. She had thick arms and her thighs stuck out. Chun-Li would’ve been impressed. She ate like a high school football player, and had become mostly impatient and demanding. Most of our interaction that wasn’t about sex or food involved her giving me commands by placing her hand(s) on my shoulder or ass to push me in the desired direction. I had started taking a daily regimen of aspirin to cope with the sore back, hips, shoulder, neck, and legs. I felt like I’d just crawled out of a car accident. Sex had become a writhing beating where Jenna pummeled me into the mattress. It was starting to become a painful chore. I’d realized that I couldn’t stop Jenna when she decided it was time to fuck. As we both got ready for the morning in the bathroom, she pushed me out of the way to use the toilet. Then she pulled me out of the shower so she could get in first. Then she shoved me aside so she could use the mirror.
That’s when I realized she had gotten taller. She had been 5’5”, and I was 5’9” – but we were nearly even in height. Son of a bitch. I came downstairs for a Saturday morning cup of coffee.
Jenna was at her laptop. “You didn’t get stuff for breakfast. No coffee for Ted until you come back with food.” she said without looking up.
“After I have coffee,” I said as I walked into the kitchen.
“Don’t make me repeat myself, Ted,” she said.
I stopped. Should I joke my way out of it, or just ignore it? I opened the cupboard for a coffee cup.
“Don’t fucking dare, Teddo. Grocery store,” she repeated.
I ignored her and pulled out a red mug. She got up and I instinctively braced myself. She put her hand on my shoulder and started to pull. I couldn’t resist. She didn’t budge a millimeter when I tried to push her back.
“You know the rules.”
I tried to put a hand in her face, but that was slapped away, and followed with a firm slap to the cheek. I tried to swat at her hand, and was slapped again. She shoved the car keys into my mouth and clutched my junk.
“You be a good Ted and come back with Jenna-food, and little Ted gets to play.”
“Ted is tired and needs coffee,” I said as I pulled the keys out of my mouth. I tried to squirm out of her grasp, but she wasn’t having it. It was like trying to move the Statue of Liberty.
“Look, if your muscle formula dealy worked on you, you could have coffee, but it didn’t, so you can’t. Go get food before I get pissed. Do you really want to ruin the weekend?”
I did not.
As I filled a shopping cart with food, I wondered if I could just cut her off. She’d probably notice the muscle loss, but wouldn’t be as aggressive. Was it worth the gamble? She was pretty smart, and she wouldn’t lose the muscle for a while. It would be a few months before I could physically defend myself. All the ‘what ifs’ went through my head: it was entirely possible the effects might be permanent. Taking her off the drug cold turkey might put her into withdrawal. She might get angry enough to break an arm. Or worse. When I went home, I decided the best plan was to talk. When I walked in the door, I heard her rummaging upstairs. I put the food away, and went up to talk. As I walked in the bedroom, I was treated to the sight of my overly muscled girlfriend abusing a giant blue dildo. I was dumbfounded. She finished and took a shower, ignoring me completely. When she got out, I tried again.
“Ted bring food?!” she mimed gorilla-like movements.
“Yes, but first, we should talk,” I started.
“I think you can recognize that you’ve become bigger, much bigger, stronger, and more aggressive than the old Jenna. I’m a little concerned, because, well, you’re basically raping me every night, and treating me like a slave. I think we should try to wean you off the drug.”
I waited for her reaction. She was still naked, but had no reaction. She pulled on a thong and a sports bra. Her breasts had grown, not to a ridiculous size, but definitely a large C, supported by growing pectorals. She pulled her hair back into a ponytail.
“Ted, I think you’d admit I’m a girl of routine, and I’m pretty sharp. Yes?” she put her hands on her hips.
“Every morning, I meticulously weigh and measure myself, and have tracked a steady rate of growth. If that changes or stops, there will be trouble. I have never felt this good about myself, felt more in control, or felt more like a … a… I don’t know what. But a few months ago, you did whatever the hell you wanted, whenever you wanted, and I was fine with it. Now I’m in charge. I’m bigger, stronger, whatever. I get to eat, fuck, choose furniture, decide our bedtime, pick a TV show, choose our vacation, or whatever. I do. Me. I’m in charge. Me.” She took a step toward me.
I realized she was between me and any sort of exit. Fuck.
“I’m not saying you’re my bitch or slave or servant, or anything like that. But I’m in charge. Do you understand?”
“Good. What do you think will happen if I notice I stop growing?”
I looked at the floor.
“Do you need an idea of what will happen?”
I didn’t answer. I started to feel hot all over, sweating.
“Answer me, Ted.”
I looked up. She was almost nose to nose with me. I realized, unfortunately, that she was slightly taller than me. Her shoulders were wider. Her arms had veins. Her forearms were thick with muscle. I knew if I moved even a little bit, she was going to swing at me, or something.
“Um,” I was stalling. I couldn’t really run.
She held my chin with her finger and thumb. “What do you think is going to happen if you screw me?”
“You’d be upset.”
“Yes, I would. What would I do to you?”
“Probably hurt me.”
“How would I do it?”
“I don’t know.”
“I am going to give you a sample.” I froze up and my stomach started to twist. She was going to cross a line, but I hadn’t done anything! She quickly shoved me up against the wall and punched the wall repeatedly, leaving a hole. My feet were off the floor.
“You are going to keep me growing. If that changes, I will break something. Should I break something now as a warning?” I shook my head. “Good. You’re going to get back on your computer, and you’re going to stop looking for a way to grow Ted muscles, and instead, grow a bigger Ted dick. Do you understand?”
“Dick. Bigger. Grow one. Do you understand?” I nodded weakly. “Good. You have two weeks.”
“Two weeks? I can’t-“
“Two weeks, Ted, or I break something. The first break will be something you can still work with, like the arm you don’t use. After that, I’ll start breaking stuff you need. Got it?” She let me slump to my knees and she stomped out of the bedroom and down the stairs, undoubtedly to forage for food. Jesus Christ, I hoped there was food downstairs.
I took the next two weeks off from work to dedicate to the dick formula. But I also kept working on a muscle formula for me. Maybe I could come up with something that would work overnight, and I’d be able to overcome Jenna. Jenna had reached bodybuilder proportions. Like, stupid 80s steroid-sized proportions. People in public stared and made hushed comments. She was up to 6’1”, I think, and had Arnold-esque arms. She had broken the bedframe from sex, and we (well, she) placed the mattress on the floor. She had started hitting me during sex, usually slapping, and sometimes she squeezed me so hard from cumming that I nearly passed out from the pain.
The last day of the two weeks had arrived, and I was no closer to finding a dick-growing solution.
“You know, if this doesn’t come through, I’m going to have to find a better lay at the gym. You really can’t take it any more,” she gloated.
That night, I stared at the computer screen. Nothing was wrong. So what was I missing? I decided to check my email when it hit me – this computer had an internet connection. I went through my logs to see what record there was of any external connections – sure enough, an IP I didn’t recognize popped up a few months ago.
Son of a bitch… was I hacked? I started over from scratch, and redid my formula, working through the night, capturing a few things I could change to speed up my muscle growth, and seeing if anything had been changed. Sure enough, something in the code made an almost-unnoticeable change that altered the formula. Digging deeper, I realized it needed a special set of circumstances to work – basically, the formula would only work on a female. I hadn’t seen it before, I reasoned, because I was simply double-checking what I thought was my own work. God dammit. I unplugged the Ethernet cable and finished up.
By the time Jenna woke up, the doses were being produced.
“So you did it?” she asked?
“Yeah, worked up until the deadline.”
“Good for you and your little dick!” she exclaimed.
I rolled my eyes.
Once they were both ready, she downed her dose but stopped me from drinking mine.
“First, we need a before and after.” She ripped my jeans in half and cupped my balls. She held out my cock and measured out the three soft inches. “How much are we going? Six inches added on? Eight?” she asked.
I shrugged. “I didn’t have a chance to test it, but my math suggests about 5 to 8 inches. It shouldn’t take long.” I replied.
“Good, because I can’t live on this nub anymore. Let’s get some photos,” she used her iPhone to take a few dick pictures. She clutched my cock in a death grip and tugged. “Let’s grow already!” She grabbed me by the throat and pushed me down to my knees. She squeezed my face to hold my mouth open and poured the dose in, then clamped her hand over my mouth. She fondled my cock, expecting the process to be automatic. “Well?” she looked at me skeptically.
“I probably need food.” I choked out.
She let me up, and I snacked on a few things.
After an hour, nothing had happened. My heart dropped.
Jenna held my junk in her hands and looked at the clock. “Looks like your new cock is a no-show. I guess I’m going to have to beat the shit out of you to teach you a lesson, then I’m going cock-shopping at the gym.”
My stomach started to hurt, when I felt a cold rush moving down. Was I seriously going to shit myself in fear? I looked towards the bathroom, just a few feet away. “I gotta go!” I yelped.
“Yeah, you’re going to go meet the nice folks at the ER.” She slapped me in the balls, and I doubled over in pain. She held my wrist in a pincer grip. “Get up. You can suck on my clit before I break your arm.”
I tried to push her off and reach for the bathroom door, but she didn’t move. My entire body felt hot, then it felt like my back started to… peel. I wanted to scream, but couldn’t. Jenna let go of my wrist as I straightened out and stood up.
Her face was all shock. “What the … fuck?”
I caught my reflection in the microwave door glass. I was… huge? It worked! I was huge. HUGE! I realized I now had several inches in height on Jenna, and was much, much wider. Jenna was frozen in place. I made a show out of cracking my knuckles. My turn. I moved forward as Jenna tried what she’d gotten used to doing over the last several weeks: swinging at me. I easily caught her hands, and scooped her up in a bear hug. She writhed back and forth to try and get free, but I was too strong. I slowly squeezed as I walked up the stairs. I dropped her on the mattress. She looked unsure what to do as I ripped off what used to be a pair of shorts, letting out a painfully hard cock. She started to scoot backwards, but I grabbed her shoulders, and pulled her face-first towards my cock. She was able to take most of it, but I pulled her off, and held her down as I drove my dick into her unwilling pussy. I used my hips to pound her, payback for her angry sex with me. She tried to push me off with no success as I unloaded weeks’ worth of frustration. I let her punch me in the chest, but she might as well have been punching a brick wall. I felt myself ready to cum, and pulled out, pushing my cock head into her mouth as she struggled. She couldn’t pull away as I pumped round after round of jizz into her mouth. My cock reached the back of her throat, thick enough to give her no choice but to swallow the entire load. I wondered if I’d gone too far, but then, she grabbed my still-hard cock. She was actually enjoying it. She pulled me back inside of her, and we went again and again. Each time, we wrestled and abused each other with slaps, punches, choking, and whatever we could do to try and hurt each other – but neither of us seemed able to actually be hurt by it. I still had the size and strength advantage. She took another load down her throat, and accepted me forcing her to take it. She rolled over and pulled her sheet up. My cock was actually going soft for the first time, worn out by hours of hard fucking. Laying next to Jenna, it was like having an arm or a front-hanging tail nestled up against her. She was asleep, but I still cozied up as a big spoon behind her. I wondered what she’d do when she woke up – would she attack me, destroy my computer and equipment, run away, or what? I wrapped my arms around her, clasping my hands, reasoning that she’d break free of any type of binding I might find, and fell asleep.
I woke up first, as luck would have it. Sunlight was starting to peek through the sides of the curtains. My arms were still around Jenna, but my hands were no longer clasped together – I guess that was bound to happen. But as I looked closer, Jenna’s shoulders seemed… wider? … fuck. I carefully pulled the sheet back. She was bigger, all right. She’d grown during the night. I guess that made sense, she’d had a dose yesterday. She was nearly my size, but it still looked like I had an inch of height on her. She must’ve felt the cool air with the sheet off, and began to stir. Now what would I do? She stretched, and rolled over to make eye contact.
“Well, yesterday was something. I guess I was kind of a bitch, but you deserved it,” she started reaching for my cock.
“Me? What did I do?”
“Uh, hello? You treated me like a guinea pig. I guess it worked out, though. All of you grew, and you ended up being a lot of fun,” she started tugging. As she looked me up and down, she paused. “Did I grow?” She jumped up, and started pulling on my arm. “Am I bigger?” She started looking both of our bodies up and down, sticking her leg out to try and compare calves.
“No, I’m still bigger,” I said.
“For now,” she retorted. “Let’s get me another dose.”
“No fucking way. You tried to break my arm,” I got up, and looked around for something to put on. I wasn’t really in the mood to fuck, even if my body was starting to get in the mood.
“You’re fine. And I wasn’t really going to do anything,” she said.
“That’s not how it sounded. We’re both done with that stuff.”
“Says the guy who’s bigger and stronger.” I found a box of speedos I’d ordered when I had anticipated muscle growth, and put it on.
“So you’re cutting me off. What the fuck.”
I didn’t reply, but she walked over and reached into my speedo pouch, pulling out my quickly hardening cock.
She got on her knees. “Well, feed me something.”
I jerked off and quickly spurted several large loads into her mouth. That was interesting; she’d never liked swallowing before. Throughout the day, we just fucked and argued about the drug. She swallowed me each time, insisting on stopping and pulling my cock into her mouth for me to finish. She was really pushy about it. I eventually had enough, and just bent her over to keep her from getting her way. She tried to fight out of it, and I ended up putting her through the wall. We fell asleep in bed together again. In the morning, we had to get ready for work. Luckily, we’d ordered clothes online, so we had things to wear to work. We wouldn’t really be able to hide our growth, though. I had no idea how I was going to explain my body – Jenna’s growth had been gradual, even if unnatural. I decided I could work remotely until I figured something out, though I had no idea what that might be. While I was deep in thought, Jenna had rolled over and put her mouth on my cock. I tried to pull her up to meet face to face, but she wouldn’t budge. Huh. I thought I had the advantage. I was able to stop her from working my cock, and she moved up towards me until she was completely on top of me. She quickly moved to hold my wrists down, before I realized it. I struggled, but her position gave her the advantage. Then I realized we were the same size. Son of a bitch. She noticed it too. She used her knees to push my legs apart, and managed to slide on to my dick. She was in control. We seemed to be even, but her position made the difference.
“Well, well. Looks like I’m still growing. You might be in trouble soon.”
How was she still growing? She hadn’t received a dose. I spent the fuck session worrying about tomorrow, but my dong did all the work. Jenna got off and went about her routine to get ready for work. I worked on my computer while simultaneously looking over the formula. The code looked like it had changed. The introduction of a certain thing would cause a female who’d received a dose to grow. That thing looked like… semen. How the hell had someone changed it? My head swirled with questions, but I was able to come up with a solution for work. With a few minor changes, I created a formula that would give me the ability to instantly change back and forth from old 5’9” lazy Ted to muscle freak Ted. After thinking about it, I made up two doses, with one for Jenna. Just to be safe, I thought, I made a separate formula that would reverse the recipient to normal, putting it into an empty tube marked “Rash Relief”, and put it on the bathroom counter.
I drank the concoction, and waited. After an hour, I had intense stomach pain, and headed to the bathroom. I spent the next hour vomiting. When I got to my feet, I was … Ted again. I was a very pale, sickly-looking version of the old me, that was for sure. My clothes hung off of me, no longer being stretched out by swollen, veiny muscle. I looked down – it was the old dick, too. I kind of wished I’d kept the monster cock, but I could always fix that later. I went back to work and waited for Jenna to get home. I wondered how she’d react to my, uh, shrinkage. --- Jenna came in that evening with a few bags of groceries. I waited upstairs as she started cooking dinner. I could feel my heartbeat pounding through my chest. Why was I so worried?, I wondered. I could grow again if Jenna came after me. But I realized that might be the end of our relationship if she really turned out to be a monster.
I started down the stairs.
“Ted, do you want-“ she froze as she saw me come down the stairs, pale and slight.
I stood there waiting for her to say something, but we just stared at each other for what felt like forever. “Hi,” I started.
“What … happened?” she had been holding a baking sheet, about to layer it with foil, and was now clutching it.
I tugged at my shirt, several sizes too large. “I’m not sure why I look like someone who’s been stranded on and island.”
“Ted, you looked that way before you grew. You didn’t really eat and you didn’t go outside.” she was looking at the floor now. “I was … kind of rough on you.” She stepped toward me, and pulled on the shoulders of the shirt. “Are you okay? Did the formula wear off or something?”
“No, I did this. I decided it’d been enough, and just reversed the entire thing,” I pulled a small vial with a top out of my pocket. “I have one for you, and… we can just go back to the way things were.”
She took the vial between her index finger and her thumb, and walked into the kitchen without saying a word. She unscrewed the top, and promptly dumped the whole thing down the sink drain.
“Wh-what… what are you-“ Before I could finish, she stomped back over to me, and drove her fist into my stomach. It lifted me off my feet, and dropped me to my knees. I was out of breath and in piercing pain. I landed on my knees, and immediately took a upwards punch to my chin. Another shot struck my right cheek, followed by one to my left that kept me from falling over. It all happened so fast I couldn’t see it. Jenna grabbed me by my hair and dragged me into the living room. Repeated hard slaps to my left cheek left my skin stinging. A fist came in hard at my shoulder driving, pushing me to the ground, followed by several more. I held back tears and cries; my shoulder was overloaded with sensations of pain.
“Fuck… you!” Jenna lifted me with her hands under my shoulders, like a small child. She held me up with one hand, while her other pulled my shorts waistband back. She was looking at my now-normal junk. “You didn’t even keep the dick. You asshole. I was worried for a moment you were sick from the formula, but no – you just wanted to put me back at – at being the little woman you can push around. Well, fuck you.” She dropped me to my knees, which were now hot with pain from being thrown and dropped.
I tried to push her away, to no avail. As I got to my feet, she punched me – right in the balls. I was curled up in agony on the floor, trying to keep myself together. I could feel her footsteps moving towards the stairs as I tried to figure out if I she’d crushed my balls. She stomped up the stairs, going for… my office? Then I heard crashing and metal scraping noises. She was destroying everything. My computer, the equipment, the formula processor, everything. A few moments later, she was back.
“That guarantees you’re tiny Ted from now on,” she said, starting to reach for me as I instinctively recoiled.
I thought about changing, growing, to stop this. I wasn’t even sure if it’d work. Or, if it did work, what if I only grew a little at a time? I figured it wasn’t worth the risk in front of Jenna.
“Jenna, I spent years working on that. Why would you do this?”
She pulled me to my feet. “No more questions. Go get the monster cock sheath. After you’re done taking care of me, you can finish dinner.”
I went upstairs as she watched, arms folded. At the top of the stairs, I could see the mess of computer parts and holes in the wall in my office. I went into our bedroom, and pulled a 10-inch rubber cock out of a bedside table drawer. As I walked by the bathroom by the top of the stairs, I could see a small plastic tube marked “Rash Relief” was still there. So I had a back-up plan. I finished cooking the dinner Jenna started, but she ate all of it. Every time I reached for something she would grab my wrist, and take it first.
“You can just eat some Saltines,” she said.
I went to the bathroom just to get a break. As I pulled the elastic waistband of my shorts down, she opened the door, and quickly grabbed my dick. She squeezed, hard.
“You know, if I want to, I can stop you from pissing. You need to ask me for permission.”
“What? That’s insane. Leave me alone, Jenna.”
She squeezed harder, somehow, and my dick felt like it was going to pop. The pressure was unbearable. “Okay, okay, please stop, please!”
She let me go. “Go clean up, then you can rub some body cream on me. Then maybe you can piss.” She watched as I cleaned the kitchen.
I rubbed her body down, which was fun, but I had to fucking piss.
“Can I go now?” I pleaded.
She opened the fridge, and pulled out a jug of water. “Start drinking,” she said, smiling.
I knew any answer but obedience would be a severe beating. I drank as much as I could. I didn’t bother trying to stall – she’d probably force the entire thing down my throat. I got about a third of the way through the jug.
“That’s all I can do,” I said, panting.
“You can piss when you finish the whole thing.” I wanted to cry, but held it together. I tried to move toward the bathroom, but she blocked the kitchen exit, and tipped the jug toward my mouth with her hand. “I can’t do this, I have to go!” I pleaded.
“If you can’t finish it, then just piss yourself.” I had no choice. I just let it go, and the wet stain on my pants grew, and began to drip on the floor.
“Oh Jesus, just go.” she said.
I hurried to the bathroom. As I finished up, I had to see if I had the ability to change on command. I wasn’t exactly sure how to do it, but … I had to do something. I balled up my fists and looked myself in the mirror. I tensed up. What should I do to make the change, exactly? That wasn’t something I could exactly program. I looked at myself closely in the mirror, and pulled off my baggy shirt. I pictured my body growing to gigantic, muscular proportions.
“Ted, what’s taking so long? You need to clean up your mess.”
I felt a burning sensation in my lower back, and my skin felt like it was peeling, quickly, almost like ripping. I could see my arms swelling, shoulders spreading out, and my chest pushing out. Veins began to pop out here and there. My stomach started to show separations in my abdominals. My forearms swelled. My cheekbones pushed out. My hands widened. I tensed again, and looked myself over in the mirror. Was I as big as I was before? It was hard to tell. Maybe I should be a little bigger. As I thought that, I grew again. My shorts were concealing an inhuman bulge of cock and balls. My thighs had ripped my short legs. Looking down, my calves jutted out. I guesstimated how big I was compared to Jenna. I should have a few inches on her, but thought I could use a few more. I looked in the mirror and saw myself get wider, taller, thicker. I looked like I could push the house over with one hand. I had to be near seven feet tall, and … Jesus, I couldn’t imagine how much all of this weighed.
I smiled. “Shut the fuck up, Jenna.”
“What did you say?!”
I heard her stomp towards the bathroom door. As she pulled on the knob, I pushed it open, and I could feel her stumble back. She had a fist in the air when she saw what I’d become. I had a good six inches and over a hundred pounds on her. I quickly took a step forward, and covered her fist completely with my hand. I realized the pain in my shoulder and cheeks were gone. Huh. She struggled to pull away from me with no success.
I trapped her in a mock hug, and smiled. “We need to talk.”
