When my “no longer curious” Bi Bro sleeps over

He sleeps with his ass towards me while I big spoon him. He sleeps only in shorts which allow me easy access. I slip them down to his knees and angle myself to enter him. The first sound out of his mouth is a masculine moan as he feels pressure against his hairy ass and hole. My morning wood demands to be attended to. His body is so relaxed post sleep as I thrust deeper inside, watching his sleepy expression turn into “oh shit you've never been so deep before.” Every time we fuck, his hole remembers. This is no exception. Morning moans are so loud and primal.
