On her very first day in college, Josephine's secret sapphic desires come to a head when she accidentally stumbles across a secret organization on campus: the Social Sapphic Pet Club. They're a group of beautiful women who engage thrice a week in steamy pet-play scenarios, divided into dominant "owners" and their chosen submissive human "pets." Josephine falls for the idea of becoming a pet, and falls even harder for the leader of the club: an impossibly gorgeous green-haired punk of an owner named Dawn who's looking for a new pet. Can the caring and dominant Dawn transform Josephine from an unhappy closeted bi with a good-for-nothing boyfriend into her happy, fulfilled, and collared personal pleasure pet?
