Brunette girlfriend sucking off stranger before sex

After a long night of partying, my girlfriend decides to pleasure a stranger. I was in the next room. They filmed the first half with my phone, apparently he got rough, took her pussy, and came hard. Then, still sloppy, she climbed on top of my cock. Their juices covered my thighs and balls. She wants to try it again. She loved being fucked stupid by a random stud. Comments, thoughts?
