I used to play a game a lot like that. living in Surabaya my gf was a very sexual mamasan. We lived at a 5-star hotel. We would sit separately at the bar, she would get a guy to take her up to our room, i would follow 15-20 mins later and "catch them" fucking. The guys were initially freaked out but soon calmed down and had to agree that to keep fucking my gf they had to suck and be fucked by me as well - it always ended up as lotsa fun.
I'd make that little slut shave that pussy and send her ass into the club to lure some guy home thinking he got lucky as hell and then walk in on them and have her tell him that he's not going to get anything unless he follows her directions and gives me some money to get some good bud and nose candy to keep me from hurting them for going behind my back and then have her tell him that he's going to be her role play husband tonight and I am going to be the visiting boyfriend who is going to be serviced by both of them and then I would leave for a bit to let her work him into the mood and return in a half hour to start the games. We have done this a few times at our local theater and twice at a bar.
