The girlfriend, horny and wanting more, encourages her boyfriend to fuck her friend's ass. He hesitates, but the sight of the two women, one on her knees, the other bent over, is too much. He lubes up and slowly pushes into the tight hole, feeling the resistance give way. His girlfriend watches, fingering herself, as he fucks her friend's ass, the sound of their moans and the smack of flesh filling the room. He pulls out, his cock glistening, and his girlfriend takes him in her mouth, cleaning him off before they all collapse in a sweaty, satisfied heap.
