I'd like to see a threesome with mother, father, and son. I think it would be nice if the story starts off with the couple talking dirty in bed in the middle of sex. The dirty talk slowly becomes incestuous. The husband starts slowly seducing his wife with this imigery until she is excited with the idea. At this point, husband has sex with wife almost to the climax point. Then he asks his wife to go into their son's room to ask him if he wants a massage with baby oil. Eventually this leads to sex and then a threesome.
