Bonyuu-chan wa Dashitai - Episode 1

Hikaru Kai is a high school student whose school senior Tomomi Sakurazawa, a cute girl with massive breasts, confesses she has a lactating body that only produces milk after swallowing semen. She hires Hikaru to suck her breasts as a part-time job. Their sessions in the infirmary escalate from nipple stimulation to full intercourse, with Tomomi begging him to inseminate her while breast milk spurts from her nipples. The relationship takes on a bizarre dynamic where Tomomi switches between being a reliable older sister, a needy "Mommy" who calls Hikaru "baby," and regressing to baby talk during sex. Over several days and weeks, their sexual encounters grow more intense and frequent, leading them to skip school for love hotel sex where Tomomi eagerly seeks pregnancy. Even in the classroom, Tomomi's cravings for Hikaru's cock and breast milk are uncontrollable. She develops a deep addiction to sex and his semen, often needing nipple stimulation or masturbating multiple times a day. The episode culminates in a montage of their sexual evolution, with Tomomi performing titjobs and participating in "Lactating Sexercise" as her maternal and infantile desires consume her completely.
