Go through my whole act to get her aroused. Run my mouth over all of her body parts like she really enjoys. Then I slowly work my way to her genitals, and get her really worked up, to the point that she starts moaning as I lightly graze her genitals with my face. Get her terribly aroused and anticipating the feeling of my mouth on her most sensitive area. Then sit up in bed, and say, "You know, just like some other person in this room, I think that performing oral sex really is yucky, I just don't like to do it anymore." And then just get up and leave her in bed all alone, and go do something else. I bet she would be pissed as h#ll, I would probably pay a heavy price, but as they say what is good for the goose is good for the gander!
