He takes me to his bedroom

Caleb turns off the shower, grabbing my arm and pulling me along with him to his bedroom. He throws me onto his bed and climbs on top of me, pinning me down on his bed as he presses his cock against my exposed ass. He lays on top of me, whispering in my ear, "Get ready slut," before pushing his cock deep into my ass, without hesitation or easing into it.

I moan loudly, pleasurably as my brother starts fucking me, claiming my second hole as his own to fuck. I continue moaning as he settles into a pace and thrusts deep and fast into me.

Caleb picks up his pace, fucking me harder and faster, "Who's a little slut for my cock, Derek?"

I moan loudly as he continues thrusting deep into me, "I-I'm your slut, C-Caleb, I-I'm your little cum slut!" He picks up his pace to reward me for admitting my new condition, "That's right my slut."

He pushes deep into my ass before filling me with his cum, "Now both your holes have been marked by me, you slut." He continues thrusting for a few moments before getting off of me and sending me away, telling me he'd request me when he needed me.
