I would do almost anything they want, even if I don't want to do it I'll obey them.
Cleaning the creampie with my mouth, suck him off, he fucking me, they going on a vacation alone, me never having sex again with my wife, her friends meeting him and telling them he is her boyfriend, she going to a family gathering of him and being introduced as his girlfriend, he living with us for some time and acting as a couple while I act as a friend, she moving out with him for sometime, days, weeks, months, the only thing I wouldn't accept is he breeding her... at least at first, maybe I would come around later...
