Beautiful testicles and anus. Wonderful to see this view of the perineum pulsing during ejaculation. I can picture the spurts that must have been a result.
I remember the first time i kissed a guys rectum when he orgasmed, just gently press the lips aginst it, it literally felt like it was kissing back with every pulse..slipped my tongue in at the end and he absolutely shook in pleasure.
