Deal.

"Deal!", you whisper.

"I knew I've found the right one. Prepare yourself!"

And with that, you hear a little rattling on the other side of the wall. Then, inch by inch, a cock appears through the whole. It doesn't look quite as big as yours, but with 18 centimeters you're above average. You've never seen someone else's cock erect, aside from porn of course.

"Well, ain't you gonna start?"

"Of course", you say and remind yourself of the agreement. You slowly take the cock inside your hand and stroke it, just like you do to yourself every other night.

"Yeah, that's it", you hear the voice from the other side.

With your free hand, you start to wank your own dick. Wait, is this getting you turned on? Stroking a stranger's dick? Well, as long as you don't see his face, it's not really gay, right? It's just a cock!

"Boy, you're good at this! But don't you wanna use your mouth a little?"
