Is it normal for my boyfriend to cum by rubbing his penis on my butt?
So my boyfriend is very obsessed with my ass. He gets hard and rubs his dick up and down my butt crack, and he does it on my bare skin. He can achieve orgasm just by rubbing his penis in between my butt cheeks. He puts it in between and squeezes my ass cheeks together, and it squishes his penis to the point where his penis is being smothered by my butt. Then he rubs up and down and usually ejaculates.
