Riki Ruskin is shocked when she learns that the hunky neighbor, a college-age boy who is friends with her daughters, has been carrying a torch for years. Riki goes from mystified, to turned on, to flirty, with the encouragement of her husband, Joel. Playing with others isn’t new to this couple, but that was a long time ago, when they were young and carefree, not fortysomething parents. Joel has never given up hope they would open up their relationship again, and he sends Riki to tease sexy Chase with his blessing. But when Riki, dressed in a barely-there Halloween costume encounters a shirtless Chase at the neighborhood Halloween party, things go from flirty to fiery.
