The babysitter
For some reason a lot of the time that men are caught cheating on their wives it is usually with women who are close to them. Maybe it’s just because they spend a lot of time around those other women and a bond is made and able to grow. Or maybe they are just unfaithful partners.
But whatever the case may be, the babysitter and the maid are usually the classical choices when it comes to guessing who your husband cheated on you with. In this case, though, the wife allowed it because she was never in the mood for sex anyways. Seems like this guy got a pretty good deal.
