An erotic illustration of a cis man fucking his ftm trans friend and transforming them into his cock, both characters look happy. The cis man says "C'mon dude, let's speedrun this transition". The transman responds "Dick noise".

โ€œFuck dude, I canโ€™t believe how much you took from me.โ€

โ€œYeah, but you love it. That feeling of your cock shrinking away, flowing into me, my dick stretching your jaw wider.โ€

โ€œYeah, itโ€™s amazing. How long does this last?โ€

โ€œJust a couple months, but then I can just drain you again.โ€ #CockTheft

A character getting off a bike commenting about how tight their bike shorts are. In the next panel they pull their shorts down to reveal a smooth featureless lack of genitals.

Created new dildos that they feel through regardless of how far away they might get, not that theyโ€™d ever get to touch their own.

โ€œBro whatโ€™s up with these new uniforms? How can we play in just our underwear?โ€

โ€œNew league rules. Something about the lack of pads encouraging us to be more careful. Just wish they didnโ€™t mandate turning us into #BulgeBoiโ€

An erotic illustration of a rubber puppy fucking a leather man and turning him into his own cock through fusion. The leather man is panting on the ground, his legs already having turned into giant testicles, he says 'dick noise'. The rubber puppy with his paw on the leather mans head is looking down at a chastity cage in his hand to which he says "you're going to need to shrink down a bit more sir if you want to fit in this lil guy".

CTF, for when your handler demands your dick should be in a cage, so you take that as him volunteering to be the dick.

When these two came over to my house and climbed into the hot tub they were in for a surprise. I had spiked the water with a special solution that clouded the water and the moment their cocks touched the air, all their length shrank away and were added to my collection of dildos. #CockTheft

Fuck man! When I said I could use some extra protein for my workout, I didnโ€™t mean like this. No donโ€™t stop, I need that cum either way. Getting bulged really helped improve my workouts, maybe you should do it too, then we can find guys to fuck us together. #BulgeBoi

I took one of those new supplements to help build my muscles. It worked well, almost too well. I spent the weekend at the bathhouse getting fucked by dozens of guys and well all that cum went right to my legs. Iโ€™m going to have to suck more dick just to even it out. #MuscleGrowth

Ha! Look at your cock pulsing and quivering. I told you not to fuck with me, and now you have a nice little curse. See now you canโ€™t actually cum. Youโ€™ll go to the very edge and just stay there, unable to cum until you have 2 cocks in your ass at the same time. #OrgasmControl

David sat on top, sliding his cock beside his bro Gabe's dick. Same as always. Gabe was still superior. His thick cut cock eked out David's by a half inch in both length and girth. But David had a new toy to try out...

As they positioned their hard cocks against one another, David clicked the button on the underside of his new cock ring. Immediately, he felt his dick heat up as his shaft pressed firmly against Gabe's. He could feel the size and power begin to pulse through his cock!

Immediately, he felt his dick heat up as his shaft pressed firmly against Gabe's. He could feel the size and power begin to pulse through his cock!

Gabe felt the heat too. David's veiny, uncut cock pressed tight against his own. He watched as his once inferior cock throbbed and stretched. He was GROWING! He stared, baffled, as David swelled to match Gabe's size... and then KEPT GROWING!!

It took Gabe a second to even realize where all this size was coming from. Then he noticed his own dick shrinking as David held it tight against his powerful, size-sapping MONSTER of a cock! He tried to resist, but David's grip was too tight. And it just felt too good... How much was David going to take from him?

#BulgeBoi have a large sensitive prostate that gets milked while being fucked and orgasm easily from it, but they only have dry orgasms that leave them even hornier. Nubbed guys just have a tiny little cock too small to use but blast cum out of it when they orgasm.

Feels good stroking doesnโ€™t it bro? Yeah those extra inches they give you when you join the frat boost your sensitivity. You canโ€™t cum unless youโ€™re fucking someone, though. You donโ€™t care about that do you though, you just want to ride that edge. #CockGrowth #OrgasmControl
