Your girlfriend has a very kinky suggestion for spicing up your sex life: she wants to invite the family dog, Rocky, to join in! First, she sucks his knotted dick while you watch, then she bends over and lets him mount her and fuck her like a bitch - doggy style! Finally, she flips onto her back so she can watch you watch her get fucked by your canine companion and begs to get bred by Rocky's doggy dick.
