As he pounded your hole you could feel your cock changing. You wanted to reach down and stroke it, but he kept your arms pinned. As you felt your orgasm run through your body your cock spewed cum onto the shower floor, rapidly contracting in size as it did. #BulgeBoi

Ever since you pulled on the jock you’d felt invigorated. You’d slimmed down a lot, but you’d also felt hornier. The problem was you couldn’t get the jock off, not even to pull it aside and get your cock out. Your only hope for some relief was if you could get fucked.

You shouldn’t have pissed off that guy. Every lick shrinks your cock a little more as you get closer and closer to cumming. Then by the time you’re about to cum, it’ll be gone and you’ll be denied. And tomorrow it grows back for you to get frustrated all over again. #CockShrink

You would think he would have learned his lesson about cursed sex toys, but he put the plug in and watched as his cock and balls shrank into a bulge. He hoped they’d grow back when he pulled the plug out, but instead the need to be filled consumed his mind. #BulgeBoi

Feels good doesn’t it? No need to worry about your little cock any more. Probably don’t have much left in your briefs anyways. Your mouth is already your primary sex organ, and a few more loads of my cum will shrink what’s left of your nub. #CockShrink

Any guy who sees your ass in the cursed jockstrap you put on immediately feels he has to fuck you. They fuck you hard and fast, dumping their load in you, though a drop never slips out. You can’t get the jock off, but you don’t really want to, do you? #CursedJockstrap

You know when we made that bet, I didn’t think I’d actually win in a race against you. I think you might have thrown the race on purpose. Just so you’d have an excuse to become a nubbed cocksucker and service my dick for a year. Maybe we should see about keeping you like this. #CockShrink

Some fucker spiked the kegs with #BulgeBoi serum at the party last night. It quickly devolved into an orgy with every guy fucking, sucking, and jacking their dicks. But after a while the serum kicked in and cocks started shrinking away. Most guys were didn’t notice until morning.

“Really? You were going to get this guy to fuck you? His cock isn’t even worth keeping.” The man ground his foot onto your husband’s cock and he cried out in pleasure. When the man lifted his foot, your husband’s cock and balls were gone, merged into a shapeless bulge. #BulgeBoi

Look at this body. Fit and slim with a nice big cock and balls. It’s almost perfect. The only drawback, I can’t cum unless I churn a guy’s dick into my load first. Any volunteers to donate their cock for my next load? #CockTheft

Entering an unknown cave was a baaaad idea. The gods saved me from the Cyclops, but apparently decided I’d be safer as part of his flock! (🎨 by @artbyhornbuckle.bsky.social) #TFEveryday #TheOdyssey
TF Sketch: Professor Scritch is being held in the palm of the Cyclops’s massive hand as he transforms into a sheep. The Cyclops’s thumb pins him down by the shoulder, and the pinned arm is almost fully transformed, ending in a sheep’s hoof, while his other hand is well on its way. Soft, fluffy wool pokes out between his shorts and T-shirt and spreads down his legs and arms and up his neck. His face has begun to push out into a short muzzle, his ears have grown pointier, and fur is beginning to spread up his cheeks. A woolly tail pokes out behind him, and his feet are in different stages of transforming into hooves, with one complete and the other well on its way. He has a worried look on his face and is surrounded by blue sparkles as he changes.

He said he was curious about what taking dick felt like and well, go big or go home #sizetheft #sizecomparison #sizedifference
His dick was throbbing so hard against mine. Fuck he's so big and his dick is so hot I can't take it much longer. Shit I need you to slow down!

"Fuck this isn't enough!" His words echoed in my head and for a moment he stopped frotting against me but as just as soon as I thought I had a moment to regain my composure I felt a new tingle shoot down my dick. "I NEED MORE" he growled out and in that moment I felt his cock pulse and swell bigger! I thought I had to have been imagining things but another pulse and his dick was dwarfing mine more than it already was. No, fuck, my dick... It's twitching and spasming out of control!

The shockwaves are shooting across my body, all I can hear are the moans I can't hold in. Each spasm of my dick makes it feel so much more sensitive, so much lighter... FUCK I AM GETTING SMALLER! "I need to be bigger so I can really split you in half" His words are both a promise and a threat. My dick is just a little nub at this point not even as big as his tip

You just had the most intense orgasm of your life, and you didn’t even have a cock. Your hookup from the night before had stolen your dick and added it to his own. As you were coming down from your orgasm you received this picture and the message: “the first of many” #CockTheft

It was almost done. It had been weeks of slow steady shrinkage, but your cock was finally down to just a little nub sticking out from your bulge. You traded your cock and balls for these muscles, but kept a tiny nub so you could still shoot cum. #CockShrink
