If your girlfriend is a bitch, then consider that variety is guaranteed for you. Look - this cutie doesn't mind getting laid by a stranger for money if her boyfriend allows it. What I find most endearing about this situation is that she doesn't cheat on him, but lets him decide the matter himself. That turns her on more than the sex. When he took the money and counted it, I got a hard-on. Deciding who can fuck your girlfriend and who can't is adrenaline and high. Don't tell me he fell for the 20 scoops of ice cream she promised him for that money. There's more to it than that. )
As for me then thin lady and the front is trashed just to the point of impossibility! True lush beautiful breasts and very flexible, and her mouth works well. So I would personally give her in the mouth and stick it up the ass. Why anal? I think although there my penis would be tight enough, in her front, he would obviously just drown without friction!
