"I want to go home...". Left alone by her parents, Hikaru has been passed around among relatives, never fitting in at school despite being a troublesome student. Unbeknownst to her, the attending physician gathers to perform anal checks on the unsuspecting patient! Young girls are activated through their anal openings. Treatment under false pretenses involves unconsented anal penetration. Day after day, her anal opening develops further, becoming two-hole or three-hole stimulation. She reaches climax multiple times, screaming out in ecstasy before collapsing in pleasure. Her pure appearance belies the fact that her anal passage is soft and tight, almost like a virgin pussy. It's impossible not to thrust one's cock inside, eliciting moans of delight. Despite this, she becomes pregnant from anal intercourse. There's still more anal treatment to come.
