2T4U/Aaron comes into the bathroom
You freeze as you hear the door open. Damn! Why did the little brat decide to come into the bathroom now of all time? It's not unusual for one of you to use your shared bathroom while the other is bathing, but the timing is just incredibly bad. You hear Aaron move to the toilet, then nothing. Curious, you peek around the shower curtain.
He is standing in front of the toilet with a rock hard four inch raging hard-on! No wonder he can't piss. Your cock makes a lurch from you staring at your little brother's immature prick. What the fuck, you think, I'm not gay!
But.... Your good buddy Gary came out to you that he was gay, after a game a couple of months ago, and after revealing that little bombshell, he had casually confessed that he'd been doing stuff with his little brother Trevor. Trevor was a black-hair little twerp the same age as Aaron, so...it was apparently possible to have sex with a kid like that. That's... really wrong, but at the same time you feel your heart suddenly start beating faster, and your breath gets short. That's so wrong, but hey, it works for Gary....
And now that you think about it, Aaron does look a little girly. His body hasn't developed into a more masculine form yet,and with his blonde hair longer than it should be, with the right clothing he'd pass for a pretty hot little girl. Stop that, you think to yourself, you aren't gay, Jack.
"Jack," say Aaron suddenly, causing you to jump a bit, "My wiener's broke!"
What do you do now?
