I take it out. I watch his arsehole re-pucker. My condom brushes his thigh and he twitches. I think it's his first time. He gets his breath back.
Men have a gland in their arse.
I find it for him and press hard with the pad of my left index finger. After a moment he sighs a bit. The noises of the dorms around us make us conscious of our situation. We're losing the sexual energy, just as I slip my finger out with a sound like the smacking of lips. He turns around ignoring my cock, and feels my butt.
