You know what? Pinches are my fav thing too...nipples, cock and balls, of course. I think it's the best feeling you can get...my girl is a pro pincher! In the nipples it doesn't hurt, even if she puts strenght in her toes. The only way it can hurt is if she sticks a toenail in the nipple and scratches. Ouch! Same thing with the head of the dick...On the balls is different, sometimes it's hard for her to grip the single ball with her toes as they keep sliding in the scrotum, but when she has the grip and starts to squeeze it's hard to hold the pain. It's much more painfull than full weight crotch standing, in my eyes...
BTW, the pics are great
