Netsuzou Trap -NTR-

Yuma and Hotaru have been friends since childhood. It is only natural that when Yuma is nervous about her new boyfriend, she asks Hotaru along with her boyfriend for a double date. But when Hotaru offers herself to Yuma as "practice," both girls realize that they're more interested in each other than they are in their own boyfriends. (Source: Seven Seas Entertainment)
