Shame. If i was in that scene with them two i be like hold her where she is so i can cum on her ass there. Doubt threesomes happen in movies but that could have been hot. As soon as she went down on him, he could have played with her errect nipples and when towards the end instead of getting off she could have slided down to play with his dick. Btw you know when you flat asses is what you like, what do you mean? What is a flat ass if you could describe it, as i see loads of nice asses in girls but dunno if you call it flat.
