Sneak into the shower

Watching Tyler stroke his meat while moaning your name has made you lose all willpower. You quickly strip, and with your hardon already halfway there, you slide into the shower behind Tyler.

"Oh, Matt..." you hear before he even realizes you're behind him as you move your arms around his waist and slowly take his cock into your hand. "Fuck!" he says, startled...but realizes what's about to happen.

"Fuck...are you..." you hear as you slowly stroke him in the shower, your dick now fully hardening against his ass.

"How fucking bad do you want me..." you whisper in his ear.

"I'll do anything you want," he says.
