[Water Valley (Mizuyan)] You Belong Only To Me {doujin-moe.us}

A schoolgirl with rosy twintails wakes to a nightmare of rope and shadow, her captor's claim spelled out plainly—she belongs to him and no one else. Bound and ball-gagged in a dark room, she's doused, groped, and reduced to tears as his obsession escalates from playful cruelty to a relentless, punishing taking that leaves her trembling on hands and knees. A yandere captivity story where every page tightens the grip around a girl who never agreed to be loved like this.
