a few times early on our dog would jump up onto my wife and then bite down on her neck as he started humping. I think its the canine way in nature to control the female and show dominance and make sure she stays put so he can penetrate her. if he can get his knot inside that is another means of keeping her from getting away from him. It scared her but said it turned her on feeling his wet jaws pressing around her neck and feeling his penis poking her vagina at the same time. there was pressure but no pain. he didn't actually bite but basically held her in place until his penis was in her then he let go. she says his front paws then squeeze and gets a tight grip around her hips while he's thrusting. his socks usually keep him from scratching her but his front claws still press into her skin on her inner thighs. she says its a hurt so good kind of pain. its makes the sex more intense felling a mix of pain and pleasure. she said thats one of the reasons she enjoys sex with a dog in that she feels like she's being dominated and forced to submit to him once he mounts her and likes the feeling of the sharp pointy claws pressing her skin and feeling his warmth inside her at the same time. she also gets off by his panting in her ear while they are stuck together.
I believe women into this really like the whole clawing, biting, scratching and fast thrusting of dog sex?
