Jason & the Muscle Serum - Chapter 4 (Consequences)

[Shelby]

Sorry this has taken so long.  Slight case of writers' block and real life kicking my ass.   Hope to get next chapter out within a week or so.

Jason looked at his flat, or more importantly, at the cum dump he had taken all over his mirror.  He knew his body was different.  The numbers he had taken earlier did not lie, nor did his eyes.  His trim belly had been replaced with a set of abs that looked like a section from a cobbled street.  It was also hard to ignore the improvements in his cock.  His dick was had been average, 6” and slim, now it was 8x6…

He normally jerked off once a day, twice if he was particularly horny..  But he had cum three times already and each time had resulted in more cum then he had managed in those golden early teen years when his balls seemed like they were a cum factory. 

Jason had always thought he was straight, or at least he had assumed he was.  He had a few girlfriends, but work and life often got in the way.  He had several gay and bi friends and never really thought about them in that way.  Sure he had got drunk once and kissed a guy at college but who hadn’t?   However, since he had seen Brad earlier, he had cum twice and both times the image of Brad’s body and cock popped into his mind.

Grabbing a cloth, Jason wiped down his mirror, enjoying the smell of his own cum.  Without thinking about it, he used his finger to put some in his mouth.  The taste surprised him, it was a bit salty but he really enjoyed it.  Moments later he was lapping up cum from his mirror.

Doctor Weinberg watched this latest development with a degree of surprise and interest. His fingers danced across the keyboard  “Subject seems to enjoy the taste of his own semen.  His sexual appetite seems remarkably increased compared to our initial observations.  .  However, lab analysis suggests his semen is not an effective vector for transmission, but will result in children with enhanced musculature.”

Jason sat down on his couch, having opened a few windows, the smell of cum started to lift from the apartment.  He had lost his gym pump but he felt fantastic, he could not stop grinning at the gains he had made.  Granted he did not understand how he had gained so much overnight, but he was enjoying the ride.

He grabbed his enlarged cock as he caught his reflection in a mirror.   “Fuck I’m pumped … I love it”.  Jason knew he wanted to get laid and wanted to experiment, without possibly ruining his friendship. Reaching for his phone he quickly downloaded an app.  He had often teased Brad for using Grindr, but he was horny and wanted to see how good a guy was.  A quick dick pick (softish) later and he was up and running…

Having shown a soft cock with a ruler at 6” he was rather popular and got several messages within the next 10 min.  He got several messages, but picked on “HotASS23”.  He was close and from the pic that he had sent Jason (Hard8) his ass was close to Brads.  “Maybe close enough that I can imagine what it would be like with Brad..”  

About 20 min later, Jason was opening the door to HotASS23.  He looked to be in his mid-20s and certainly had a decent body.  Sadly he was nowhere near as built as Brad, but he was ripped and the same height as Brad, with an equally tight looking ass. Plus, Mr Ass23 was, as advertised English, and Jason loved the accent.    

“Hi I’m Chris” Mr Ass offered a handshake as he stepped into Jason’s rapidly cleaned apartment.. “I believe you’re expecting me Hard8” Jason grinned, flashing his perfect teeth and twin dimples; he nodded and closed the door behind Chris.  Within seconds they were kissing..  Chris was clearly VERY excited by Jason’s body, as his hands explored the bulging muscles barely contained by Jason’s t-shirt and shorts. (Well it was summer)

The writhing mass of hands exploring each other’s bodies moved from the door to the couch.  Jason fell onto the couch and Chris was on top of him, straddling him.  Chris ripped Jason’s shirt off his body, clearly eager to explore the mass of muscle before him.  “Damn you’re a big one” Chris squirmed against Jason’s crotch “and getting bigger by the second”

Jason lay there, partly in shock at how aggressive Chris was, but also loving it.  His body seemed hyper sensitive as Chris ground against him and licked his pecs.  “Oh god that feels good” He could not believe was he was doing as he pulled Chris’ face towards his and kissed him.  It was like something went off deep inside Jason as his tongue explored the inside of Chris mouth.  His body responded…

Chris was clearly loving his experience and his hands moved over Jason’s hard muscular body.  He twisted Jason’s left nip as his right hand ran over the washboard abs, down towards the waistband of the shorts.  For his part Jason was lost in kissing his Chris and grabbing onto his tight ass…  “Fuck me hard with that 8” cock of yours” Chris’ voice was low, almost a whisper in Jason’s ear.  The request was honest and earnest and one that Jason was more than willing to oblige.

Jason moved slowly, letting Chris enjoy every moment.  He slowly proceeded to slide Chris’ trousers down, caressing his legs as he went.  But something was building within Jason, a burning desire to fuck.  He was hornier then a rhino in mating season and becoming more so every moment.  His dick swelled to full mast, but little did Jason realise it had grown again.  It was no longer 8x6, instead he had  a pornstar  worthy 9x6.5.  “Ok…” Jason grabbed his dick, and at that moment he knew it was bigger.  He flashed his best shit eating grin “ you asked for it Chris”

There was no way that what followed would be described as making love.  It was most definitely fucking.  And the state of the room afterwards meant it clearly it had been “highly energetic fucking”.  It looked like a tornado had gone through the living room.  Things had been knocked over, moved and even the wall had a small crack in it.  The whole place stank of sex.  Lots and lots of sex.

 Jason’s balls had gone into overdrive.  He had fucked Chris and then seconds after he came his dick went soft for a moment before getting hard once more.  Chris, the eager size queen had sucked him off, impressively swallowing nearly every drop of the massive cum dump.  Jason had got hard again at the sight a few drops of cum escaping Chris’ mouth.  Chris noticing the re-hardening and begged Jason to fuck him again, not wanting to be a bad host, and marvelling at what was happening  Jason had been more than happy to comply.   

 Jason had pounded Chris’ ass like a jackhammer and cum heavy a third time.  Totally exhausted, Chris had fallen asleep moments later.  As he pulled out, Jason’s dick softened for a moment or two.  As he looked at the sleeping form of his fuckbuddy, Jason grinned as his felt his cock grow steel hard again for the fourth time.  Jason grinning had proceeded to jerk off and covered most of Chris’ hot torso with warm cum.    

Finally Jason’s dick returned to a limp state, Jason caught his reflection out of the corner of his eye.  Yes the mirror had been knocked in the vigour of his fuck session, granted it had cracked but as he looked at his body he could help but notice, he had grown a little bigger… Everywhere.

“Fuck me, that was intense.”  Jason looked at the room and laughed. “I fucking loved that, it was better than any woman I have ever been with.”  He flexed his double bi, noticing he had grown a little taller as well.  He took his cock in hand, enjoying the heavier heft he felt.  “Man I wanna men 24/7 if this is what it feels like and does to me. “ 

BUZZ

He looked at his phone  “Jason you got a Grindr profile!?”  The message was from Brad.. “want me to cum over?”  Jason looked at the state of the room.  And replied.  “Give me an hour, I’m cumming to you.”
