If you asked your brother to sleep with your wife because you wanted children?

would you regret it after? My brother and his wife have been trying to have children for years and after many tests it turns out he's a jaffa. So, they asked me if I would have with her and then they would treat the child as their own and we all took a solemn promised never to say a word to anyone. My brothers wife is so horney I couldn't resist the offer and went round their house every Friday evening for 2 months. At a family dinner last week my wife asked them how it was coming along etc when she jokingly said they could "borrow" me but that wouldn't help as I've had a vasectomy, you should have seen my brother's face.
