The walk back to Mark’s place was quiet. Mark seemed lost in thought. I felt as if my poor brain was short-circuiting. What does all this mean? What will this growth do to Mark? To our relationship? Will he be the same person? Am I the same person? I can’t keep my eyes off Mark – or more specifically, his new muscles. With this new growth, he’s now just a bit taller than me – but not enough to really make his pants look short. But it’s his muscles that are stealing the show. His shirt now clings tight across his pecs, and the neckline can’t hide the flared mounds of his traps. The sleeves are stretched tight around his bulging arms – which highlights the swell of his delts. I can see the muscles in his arms flexing as they gently swing with every step. But my gaze keeps returning to his pants – his muscle growth is really impressive down there. His pants cling to his well-developed quads and are now stretched tight across the shelf of his sexy booty; so tight that the pants sort of ride up and cinch under his butt – making the front pockets flare out like two elephant ears. Speaking of elephant… I can clearly see the massive outline of his erection pointing toward his hip – almost sticking out of his pocket at the waistline. It bobs up and down with each step he takes. Damn he’s hot! We arrive back at Mark’s apartment; he misses getting the key in the keyhole. “Hmm… The keyhole is a bit lower than usual.” He ushers me in and closes the door behind us. For a moment, we just stand there in silence staring into each other’s eyes. Finally, Mark lets out a sigh. “You must be a ball of emotions.” “Read me like a book, you have.” My tired attempt to channel some Yoda to lighten the mood. He smiles. “Like an open book, you are.” His ability to be nerdy is one of his many adorable qualities. But his genuinely warm, charming smile steals the show. And to have all that bound up in this tight package of muscles is just kryptonite for my heart. “It’s been a day.” Not knowing how else to sum up today’s turn of events. “How are you feeling?” He sort of spreads out his arms and looks down at his body. “This will take a bit of getting used to. But I can’t lie, I feel amazing. My body feels hard, dense. And I’m horny – like really horny – my cock feels like it’s going to bust out of my pants. Did Shawn mention anything about feeling this horny?” “Well… Shawn would typically cum after each round of growth. So maybe that’s the answer to your question. And we were focused on getting out of my dorm – so you haven’t had that opportunity.” Mark pulls his shirt off – revealing an impressive, dense-looking six pack of abdominals – tight and hard. He previously had sort of a lean, slightly muscle-y frame, but now any fat has disappeared, replaced by hard muscles vacuum-sealed under a thin layer of skin highlighting the dense cables of each muscle fibre. He runs his hands over his abs, and up to his pecs, giving them a squeeze. “Well, if he has a fetish for muscles, then this sort of growth would be quite a turn on.” “Yes, quite a turn on.” I say almost hypnotically – watching the muscle fibers in his shoulders dance as he feels up his body. “This feels a bit unfair. You’ve been working so hard in the gym to earn your hot muscles, and I’ve gotten these without any work. And I believe I may now be a bit buffer than you – no offense – you’re still a sexy muscle-stud.” “No apologies. You rescued me. And… This is so…hot.” I can’t resist. I reach out and cup his pec, giving it a bit of a squeeze. My thumb slides into the cleft between his pecs – I can feel the individual muscle fibres as they undulate beneath the skin. His skin is quite warm, and his muscles are hard – there’s no visible fat, so no cushion to soften those dense muscles. “Mmm…” I let out a soft moan. Once again, my hardon is straining in my pants. “Corr. You’re killing me here.” Mark reaches down and unbuckles his belt. I can see his erection – straining to poke out of the pocket at his hip. He undoes his button and unzips. In order to get his pants down, he has to push his boner in toward his hip – and with some stretching, he’s able to get his pants down past his impressive obstacle. He shucks his pants and stands straight up – he only has on a small pair of sexy red briefs – which are completely defeated by his massive hardon. He’s so rampantly erect that it’s pulling his waistband away from his hip – and I can clearly see a girthy piece of meat that’s almost as thick as my wrist – and long enough to poke past his hip. Previously, I had only caught a brief glimpse of his flaccid cock – which was still a good size. And I had certainly felt his boner through his pants – so I knew that he was carrying an impressive tool. But now… Mark reaches down and gives his boner a squeeze through his briefs. He lets out a low growl of pleasure. “…so horny…” Mark pulls his briefs down and releases his cock – the thick tree-trunk stands perfectly straight out from his body. “Oh fuck.” He’s perfect. “Yes, that’s exactly what I want to do.” He replies. He leans in for a kiss. I grab on to his hard delts and pull him in. He cups my ass with both hands and drives his tongue into my mouth. I run my hands across the mounds of muscle in his back and try to squeeze his firm glutes – they’re solid. His hard boner is sandwiched between us, I can feel it poking up into my abs – a very thick pipe that almost reaches up to my nipples. With tongues intertwined, we start making our way down the hall toward Mark’s bedroom. He pulls my shirt off over my head. And having his tongue out of my mouth gives me a moment to speak. “Mark. How is this going to work?” “Oh yeah… You have a point.” He picks up on my concern. “Perhaps a condom?” “That should work.” Mark leaps off to the bathroom while I strip off the rest of my clothes. He returns opening the wrapper and taking out the condom. He’s framed in the light from the hallway – the outline of a physique model who’s taken a liking to the gym. His glorious tree-trunk cock pointing directly forward is bobbing as he walks. I’m already at full erection, and my balls churn at the sight of the gorgeous hunk of man. “Let me get this on you.” Mark kneels down in front of me, grabbing the base of my dick. “You have such a beautiful cock.” And just before beginning to roll on the condom – he quickly rams my boner down his throat – providing a bit of lube for the condom. I can see a bit of moisture on his lips – was that pre-cum, or just saliva? If it was pre-cum, it likely wasn’t enough for any noticeable growth. Now that I’m covered, Mark stands up and we resume our tongue fencing. I used to be stronger than my nerdy boyfriend – but I would now agree with Mark’s assessment that he’s got the upper hand in the muscles department. He’s able to manhandle me down onto the bed – he’s on top and has me pinned – not that I’m trying to escape. My one hand is trying to make a dent in his ass, while my other hand is strumming across the ripples in his deltoid. Our two cocks are grinding against each other, fighting for space between our sandwiched bodies. I can feel the heat from Mark’s thick cock – and he’s leaking pre-cum – which is providing some lubrication as he’s grinding on top of me. Mark whispers, “I need to fuck you.” “With that giant piece of meat?” “I’ll go easy.” Like any good gay boy, Mark has a bottle of lube stashed beside the bed. He’s already got me on my back – he lifts my legs in the air and positions himself. He gently massages my hole with a lubed finger – teasing. My cock throbs and my balls churn with anticipation. He leans in for a lingering kiss, and then plants a trail of kisses down my neck and across my chest. His finger is gently massaging my prostate. My balls tighten up; my cock throbs. Mark removes his finger and directs the lubricated head of his cock toward my tight hole. I can feel the warmth and the moisture as he gently rubs his cockhead around my sphincter. He’s taking his time – my cock is throbbing in anticipation. Mark slowly begins to apply pressure, gently. He’s a pro at taking his time. His teasing is effective – my anxious anticipation is turning into eager desire – I want his cock deep in me. I feel the release as the thick cockhead fully enters. Mark pauses for a moment, leans forward and plants another string of kisses across my chest. I can feel him slowly rocking back and forth – applying just enough pressure to ease his massive cock in a little farther, and then backing away enough for me to feel the release. My cock is pulsing – I can feel every heartbeat in my raging erection. Mark continues to rock back-and-forth – his cock slowly driving deeper – I can feel the engorged head pushing its way farther up my ass. Finally, I can feel his firm balls nestled into my glutes. Mark takes a pause, leans forward and gives me a gentle kiss. Then he starts grinding – rocking back-and-forth – his cock pushing and pulling deep inside my ass. I am in ecstasy – my balls are clenched tight – my cock is on fire. He’s grinding my boner between our bodies. My hands are clamped tight on his glorious muscles – dense and hard to the touch. I can feel myself nearing climax. And I can also feel Mark nearing climax – as I can feel his thick cock swelling with the approaching orgasm. As he nears the edge, I can feel his muscles clench in anticipation – getting harder underneath my hands. This just excites me further – and then… Through my clenched teeth, “I’m gonna cum!” And I can feel the moisture flood my abs. Oh no! The condom has come off! It’s been dislodged with all that back-and-forth grinding. Mark hasn’t been swelling with an approaching orgasm – he’s been absorbing my pre-cum! And now I’ve just cum all over my abs! Mark is still lying on top of me – still eagerly fucking my ass. And now I can feel my cum drying up, being absorbed by Mark’s already gorgeous body. The first thing I notice is the surge of growth in his cock – the thick cockhead pushes a little deeper and the girthy shaft swells further. I can also feel Mark’s muscles growing – he’s becoming heavier. His pecs widen and push harder into my chest. I can feel his delts widening and thickening underneath my hands. And his eyes inch slightly up toward mine as he adds new height. He’s clearly stronger than me now – his thrusting is increasing in intensity. Impaled on his cock, I’m grinding on the bed as he’s fucking my ass. “Oh fuck yes!” (that’s me) “I’m gonna cum!” “Cum in my ass Mark!” I can feel his cock finally swell with the oncoming orgasm. The hard muscles of his body lock up – he freezes in place as his balls clench, his cock surges – and I can feel the intensity of his orgasm deep inside my ass – shot after intense shot. After the eternity of orgasm – Mark unfreezes. He collapses on top of me in exhaustion. His body is weighty – but even post-orgasm, his body is still densely-packed, hard muscle. He picks his head up and gives me a tender kiss. “You’re fucking amazing.” He has the more adorable post-sex puppy dog eyes and warm smile. “Thanks. You’re amazing too… And, if you don’t mind me saying… also rather heavy.” “Oops.” He lifts his torso up – and I can breathe freely. “Be gentle coming out.” Referring to his massive cock still stuck up my butt. “I’ll go slowly.” His cock was massive before, but now – even post orgasm – it is gigantic. Definitely as thick as my wrist – and hanging over a large set of balls, it is still hanging half-way down to his knees. The rest of him is just as impressive. Mark stands up beside the bed. His frame has filled out. He’s developed a gorgeous set of rounded delts that are corded with muscle fibres. And where the mounds of his delts come to a taper, out springs the mountains of his biceps and triceps – his biceps look as if he is smuggling a pair of softballs under his skin – and each one has a prominent vein. His pecs have become a bit of a shelf, pushing out over his abs. The ridges of his abdominals are now more prominent – and are clearly showing a solid eight-pack. His stance is now wider to accommodate the growth in his quads, which flare out from his tight hips to give him an impressive “X” shape. I stand up beside him – and I am now looking at least two inches up whereas before we were close to the same height. “I guess I’m going to have to get used to being the short one.” “If this happens every time we have sex, this could start to become a problem. How about we shower and get to bed – it’s been a long day. In the morning, we can discuss plans.” Although I really wanted an excuse to get my hands all over Mark’s muscles, we decided it would be safest to take turns in the shower. We curl up in bed. Due to Mark’s new size, it just makes sense for him to be the big spoon. He wraps an arm around me, and we curl up together. His muscles are firm, and I can feel the very sizeable lump of his cock nestled in the cleft of my ass. His breath is gently tickling my neck. This is heaven – and I am quickly asleep. 36 3 1 Quote Link to comment Share on other sites More sharing options...

The next chapter is partially written. The full story has been "story-boarded" since the beginning. It's just a matter of figuring out how to write the details in a way that keeps the story on the path to the "right" ending. I think the "foreshadowing clues" that I've sprinkled in the story thus far have been maybe a bit too subtle (or maybe subtle enough that once the ending is revealed, you'll have to go back to see the foreshadowing breadcrumbs). But it has been quite an interesting challenge to try and find balance between "being true" to the characters and also keep the story moving toward this pre-determined ending. My apologies that this has been such an agonizingly slow process. This isn't the sort of writing I normally do. I only started this as a way to say "thank you" to Xyggurat (and the other writers on these sorts of forums) for their beautiful work. And now, after struggling to do this sort of writing - I've definitely developed a deeper respect for these writers on these forums. 13 1 Quote Link to comment Share on other sites More sharing options...
