Rough doggy becomes less fun -to me at least- when the reason she supposedly wants it is because she's imagining her brother raping her.
Besides, I'm a breast man and I need eye contact. I go limp from doggy unless we do it in front of a mirror and I can see her face and breasts.
I have, she was hot but absolutely batshit crazy and destructive.
This is the problem, not the sex. Love shouldn't stop at pomf.
So all the girls I have dated claim they were assualted or raped, but only a third of them really were and those that were want you to pretend to rape them all the time
and want to be slutty.
