Geoff Robinson has no reason to feel insecure in his marriage to Patrick Walsh, even with Patrick’s polyamorous past and Geoff’s own inexperience. When Geoff starts fantasizing about bringing a woman into their bed, he has to admit that he’s trying to appease his own curiosity, and not Patrick’s. Threesomes are exciting, and surely one night of fun won’t cause any problems. With the ink still fresh on her PhD, Lori Clark is finally ready to move to a bigger city and pursue her dream job. Her time in small-town Mapleton has an expiration date, so there seems to be little harm in a fling, even a fling with her sexy coworker and his husband. One night is never enough, though, and their chemistry together hints at the possibility of more than just an affair. The excitement of a new relationship makes Geoff and Patrick wonder if they’re just infatuated or destined for non-monogamy, but Lori’s future plans are pulling her away from both of them. Can a marriage survive when two people in love… both fall in love with someone else?
