Close sisters who share a room divided by a curtain. Whenever the older sister's boyfriend stays over, they have sex while trying to keep their voices down because the younger sister is always right next door. The younger sister would masturbate using her sister's erotic sighs leaking through the curtain as fuel. Noticing this, the boyfriend gives the younger sister multiple creampies while the older sister sleeps, sending her into repeated orgasms. Eventually, the younger sister begins to crave raw sex and raw creampies on her own.
