After resuming our relationship following a one-year break, my girlfriend and I began living together. She's become brighter and cuter than before, and I've noticed subtle changes in her behavior. These changes are especially evident during sex, as she's started seeking out more abnormal elements like choking, nipple pinching, and bondage play. Over the course of three days of everyday life together, our relationship gradually deepens. How will this new dynamic with my girlfriend, who reveals her secret masochistic side, continue to unfold?
