Sissy-m-3 - NSFW

Both your wife and her boyfriend like having you drive her to his house and then wait -- however long it takes -- to take her back home with you after he is finished using her.

Sounds like a pretty good deal, right?

Tonight marks the fourth night in a row that your wife and your room-mate from college have taken over the main bedroom, relegating you to the couch or the basement. When he came to town on business, you had invited him to stay with you and your wife -- but you thought it would only be for two or three nights at the most, and you certainly didn't anticipate that he and your wife would get along so well. But what could you do? You couldn't very well kick him out, and in any case, when you've hinted that you were expecting him to leave soon, your wife had gotten angry with you and told him that as far as she was concerned, he could stay as long as he wanted.

Sounds like a good time!
