The Cunning Girl Easily Seeded, Fertilized, and Implanted

High-schooler Aoyagi Saeko, who works part-time for tuition, hides cheat notes in an eraser on the graduation exam because of low attendance and a waiting job. Her three-year homeroom teacher Shouji catches her, takes her to the guidance room, threatens her with being held back, and offers to overlook the cheating if she accepts one week of sexual “guidance,” then forces oral sex on her. At his empty home he gropes her breasts, uses aphrodisiacs, binds her, examines her with a speculum, inserts vibrating beads into her cervix, and continues with vibrators and oral stimulation until she climaxes and squirts repeatedly; she resists at first but gradually becomes more responsive. On the final day he makes her choose ovulation drugs and becoming his woman to graduate, takes her virginity, and repeatedly creampies her while ovulation, fertilization, and implantation are shown. Pregnant immediately after graduation, she marries him, keeps her part-time job, and continues their sexual relationship.
