Playing the asian creampie whore

One of the guys who regulary come to the gangbang parties also has an asian wife at home. But she seems to be far away from what I like to do. He asked me, if prior to a gangbang party I could play the creampie whore for him and he can imagine, his wife is in front of him doing all the nasty things he likes. Well, I am always into roleplay and I did the favour. I just asked myself, we he is so shy asking his wife to come along to one of the parties. I could teach her :)
