"Upstanding" gentlemen? I think I know what that means.
I got a great mental image of a girl working a 4-guy party. First she's in a little French maid outfit . . . perhaps with her hair up. As each guy arrives she greets him, seats him in the living room, takes off his shoes, asks what he'd like to drink.
After all the guys are arrived and seated she goes into the bedroom to change. She comes out in some beautiful erotic lingerie, with her hair down. She does a little dance for the guys, and they gradually get hotter and hotter. They undress and once in a while one of them beckons her over, has her get on her knees in front of them. She provides a little oral service, not too much, mustn't end his fun too soon.
She does this for a while, first one guy and then another, and the guys are getting more excited and some of the action gets more heated, while she's orally servicing one guy another is behind her, rubbing her breasts, grabbing her ass, unhooking her lingerie, . . .
Ok you guys put your hands back on the keyboard now.
