My childhood friend and first love, Ena, suddenly appeared before me. She was exhausted and fell asleep, and seeing her like that made me aroused. Noticing my desire, Ena kindly offered to relieve me. From that moment on, a strange cohabitation began. Ena confessed she wanted to become my pet, so I put a collar on her to fulfill her fetish, and we gradually sank into perverse acts. As our relationship deepened, we experienced various intimate episodes to confirm our feelings for each other. The special bond hidden within our daily lives drew us closer and stronger together.
