Even if she wants that, which is pretty hard to tell, he is absolutly not the man for that job! More focused at his own mug and the camera then his girl, she's not relaxed enough to enjoy it so she's probably cramping what causes her agony. In germany we have a word for that kind of guy. Its "taschendom" (someone who claims to be a dom, but in truth is just someone who doesnt know shit about what he's doing and therefore causes trauma (physically and mentally) so basically: idiot.
I wonder why he’s always looking at the camera vs. her asshole. It’s hard to tell if she’s pounding the bed in pain or pleasure. I think she should do this to him to show him how to do it properly.
