Months after the death of her husband, Karen sought solace, and much more, in the arms and bed of her oldest son, Jeff. Over the past year the two have lived as lovers and they couldn't be happier. Not only are they deeply in love, but the taboo sex couldn't be any hotter! The only problem is keeping it secret from Karen's younger son, Jimmy.

With Jimmy away at college that hasn't been difficult, but that changes when he comes back home to spend the summer. Karen and Jeff do the best they can to stay apart and keep up the act, but when they think they can catch a quickie and Jimmy catches them, the cat's out of the bag.

Jimmy is upset, but not for the reason they think. Karen assumes he's mad because what her and Jeff are doing is wrong, but she's wrong. Jimmy's upset, but not angry, he's jealous because he wants mom too!
