Sucking Dan's Dick

I sit next to a nice but slutty girl - Sarah. I mean she really is slutty, not just for pretend. She will go out and meet a guy in a club and take him home and fuck him. Then she comes back and tells us all about it. I will admit it does turn me on to think about but the safety issues and all keep me from doing anything so wild. Last night about midnight it slowed down and she got up for a break. I was thumbing through a magazine when I heard Dan moaning from the other room. WTF I'm thinking. This perve is jacking off or something while listening to the other girl (there were 3 of us last night). I get up slowly and quietly and peak toward his room and see Sarah on her knees in front of him blowing him. No shut door - nothing! I don't think shit like that happens even in strip clubs. I think he wanted us to see it. I really fucking hope we get set up at home or I'm finding a more reputable sex phone job.
