Part 1

Finally I’m ready to try the new batch on someone other than myself. I have decided to choose my subject on a Sunday so he has time to adjust before resuming a normal workweek. The dosage is moderate, one small scoop in a cup or more of water. The flavor is rather neutral except when combined with chocolate. I have no idea why. Hell, I’m just a hobbyist with this shit and there’s plenty of “I don’t know why”! I had to linger a bit in the locker room before my subject arrived. A tall, lean fellow of about 40 years with a penchant for loose tank tops and biker shorts. I saw him change into a jockstrap that held his junk just right and don a grey pair of shorts that didn’t really accentuate his average bulge. When his back was turned I swapped his orange shaker cup with an identical one I’d brought with the mixture already prepared. I watched from a distance and waited to see the effects of my little experiment. Observations were supposed to include the length of time it took for effects to show and the kinds of reactions he might have. It took about 23 minutes after the first swallow for him to discreetly try to rearrange his jock. I began using equipment next to him to observe more closely. His bulge was noticeably larger and apparently annoying the subject slightly as he attempted several times to get more comfortable. Fuck, this was awesome! In my own experiences there was no pain or itching, just slow steady growth over the course of an hour. I tracked the subject throughout his workout but kept a normal pace of varying distance and closer observations. I also observed a few men blatantly staring approximately 45 minutes after the first swallow. Subject was just finishing ten minutes of cardio and I hurried into the locker room to get into position to observe the shower. I was half undressed and half a bench away from subjects locker when he appeared. His bulge was nearly at its fullest with about ten minutes of growth time left. I attempted disinterest as he began to strip but made note of his demeanor. Somewhat confused, somewhat disconcerted. I tried to engage by asking if he was okay. He’d said he was good and I got to see him pull off his shorts. His overstuffed jock had given up holding his balls in place and I could see the flesh pushed out on both sides. When he lowered the underwear his huge nuts dropped and swayed heavily. I saw him look around before weighing them in his hand. I followed him into the shower but he was well distracted and seemed not to notice anyone else. As he showered he repeatedly washed his sac and kept lifting and examining himself. I don’t think he noticed his own cock half hard and drooling a continuous strand of precum. I was nearly fully dressed when finished his shower and returned to the locker. I made a trip to the bathroom, combed my hair, did anything to stay longer. I watched as the subject pulled his gym bag out and dried himself, applied deodorant, and combed his hair while remaking nude. His cock stayed semi-enlarged and continued to produce slow, thick drips. His balls were the size of two lemons and hung down much further than his cock. When he dressed he put on briefs and the waistband pulled away from his abs due to his considerable mass. I watched him struggle with his jeans before opting to wear the gym shorts home. I watched from the juice bar as the subject left the gym. His huge bulge was pushing his semi out enough to clearly see his outline. His precum had already begun to soak through both layers. I caught up to him at his car as I was parked conveniently behind him. I asked him again if he was okay and told him he seemed out of it. I wanted to get more of his reaction to his experience. He was more receptive this time. He began telling me he feels great but he couldn’t fit into his jeans that he wore today. I nodded and looked at his crotch. I remarked that it’s obvious he was more “gifted” than average. He smiled and thanked me for the compliment. I couldn’t stop staring. His final size was incredible. He didn’t move and let me have a good look. I watched as the precum stain grew larger and his cock grew harder. He reached into his underwear as I watched and grunted as he tried arranging things. I looked at his face and saw the faraway stare of a man lost in lust. I opened my car door to shield up from view of the sidewalk and nearby buildings and when I looked back I saw he had hitched his shorts and briefs under that prodigious ballsac. His solid boner was a broken tap and the precum in a solid line. He faced me and smiled. I felt like I was being viewed as prey. Strong hands gripped my shoulders and pushed. He said nothing but his cock throbbed in my face as I sank to my knees. His precum puddled on my T-shirt collar as his head swelled a centimeter from my lips. I heard him repeating “yes!” as he pushed his hardness down my throat.

Part 2

I looked up when I heard the phone buzz a reminder at me. I’d almost forgotten I had a date tonight. I got distracted trying to create capsules of my formula to try out on different men. I had three small bottles with a couple of doses in each. The dose I used for my gym subject a week ago was the amount I put in the capsules in the bottle labeled “average”. The other two bottles were labeled “high” and “low” for dose description. I regarded the average dose as quite powerful and wasn’t ready to try anyone on the high dose formula. Low dose was half the average and I was curious about its effect on both cum production and libido. I’d decided tonight I’d find out. I met Randy outside his condo and we walked over to the MaxiPlex Theater for the new super hero flick. He was into it and I enjoyed seeing him come out of his shell a bit when he got carried away with the action. We’d been on several dates and had done nothing sexual. I thought it was odd for a couple of middle aged men who were dating to be so chaste with one another but I was not a very aggressive guy and Randy was very shy. Last week he’d dropped me off after a dinner out but stopped me before I got out of the car. “How come we’ve never kissed?”, he asked. I shrugged and looked at him. He leaned over and kissed me. I kissed him back and it lasted a few seconds. When he leaned back I asked him if he’d like to see a movie next week. I had been thinking about sex with Randy every day after that and wondered what a smaller dose would do to his shyness. I wasn’t sure I wanted to try it without his knowledge but I thought it would be a better gauge of it’s raw effects if he didn’t know. But first I wanted to figure out how receptive he’d be to the idea. This movie would be the perfect cover for the conversation topic. We sat in the back of the nearly empty it theater so we could talk without being heard. Randy liked to comment on the movies and I liked giving my reaction to scenes, too. Toward the beginning of the movie I asked Randy if he would want super powers. “If you were given a formula that made you greater in some capacity would you take it?” I said. “Hell yes!”, Came his enthusiastic reply. “Don’t you want to know what enhancement you’d get?” I questioned. “Even if it was lame like I’d be able to light a cigarette with my finger, I’d take it!” He gushed. And I had my answer. During the first slow part of the movie I whispered I was getting popcorn and I slipped out. I returned with two small bags and handed Randy the low dosed treat. I smiled as he attacked it with gusto. “Thanks!” We settled into the film and were fairly engrossed when Randy began getting a bit restless. I could see him adjust his crotch and knew he would be fully affected in 20 more minutes. He lifted the arm rest between us and placed a hand on my leg while he watched the movie. I could feel him look over at me several times and when I knew he was at the peak of effect I returned his look. He was searching my face for any hint of approval but I tried to remain neutral in my gaze. His arm had moved to drape over my shoulders and I felt him lean over while pulling me towards him. Without asking this time he kissed me. I could feel his leg press against mine as his kiss grew hotter and more hungry. He slid one arm dow my back and rested his hand on my ass as his other arm pulled me closer to him. I heard him in my ear. “You have the most beautiful ass.” He gripped my hand and pulled it to his crotch. “This is what you do to me, you fucking stud.” I felt his hard cock and a considerable amount of wetness there. My hand caressed his enormous nutsack. Easily the size of a big grapefruit I could feel it swell more as I held the mass. The hand on my ass worked down my shorts and I felt him feel my hairy crack. “I think I’ve waited long enough”, he rasped. He’d let go of my hand and fumbled at his zipper. Once he had his shorts open he guided my hand there. “Take my cock out”, he demanded in a low growl. Then he reached up and grasped the back of my neck firmly while he instructed me. “I think you are so damn sexy and right now you are going to show me how much you like me!”. He shoved my head down into his crotch and held me there in a steel grip. His growl came again. “Show me! Be a good boy and suck my fat cock!” He shoved my head down onto him and his pure slickness penetrated my throat on the first try. “oh fuck, you are so damn hot! This is not going to take long!” He kept his tight grip and pumped up into my throat. His other hand had found my hole and he pressed a finger into me. “When we get home I’m giving you a load in this perfect ass” he warned me in low even tones. “oh fuck, you are getting your first load now!” He panted, trying to keep his voice down. I felt his nuts expand even more and precum ran down my chin. I felt his cock widen and knew. But he couldn’t help it, he had to verbalize everything. “Take my fucking load! Swallow me! Fuckfuckfuck, this mouth is mine!” He’d bent over and whispered hoarsely in my ear. “drink it all, baby. I own you!”

Part 3

Randy sat back panting from the explosion of cum he’d just drenched me with. I raised up and looked around the theater. The few people up near the front were unaware of our actions. I settled back in to watch more movie but Randy had other ideas.

“Let’s get out of here”, he whispered.

Out on the street, even in the dark I could see the cum darkening the entire front of his shorts and the huge bulge there was pushing his thick shaft outward in an obscene profile. As we walked he put his arm around my shoulders. This affectionate and aggressive side of him was very sexy! At the corner he stopped and kissed me, hard. I felt him lick the wetness in my beard and growl.

He looked into my eyes. “You took my load like a hungry cocksucker. That was so perfect. I think you’ll make such a good bottom!”

I started to tell him to slow down but he was still making plans. He put his forehead against mine and held the back of my head. In a low voice he continued, “I want more of you. I want you to tell me yes to everything I say, I want to already feel a need to pump more cum into you. My fucking balls are aching again and this time I want to pound my load into your beautiful ass. Are you coming home with me and getting fucked all night?”

I pulled back slightly and nodded. I was dumbstruck. My cock was rock hard and I felt myself throb as I looked at this man.

Randy pulled my hand to his crotch and I felt fresh wetness pump from his stiff meat. He looked at me lustily. “You feel my need, don’t you? Get your hand around my bulge and tell me YES.”

I had no free will. I immediately said YES and felt him actually squirt precum onto my palm. I lifted my hand and stared at the thick lube he’d forced through his shorts. Then I licked it.
