Mai, a daughter who was caught masturbating by her stepfather. She looks troubled when he smells the tissue she used to wipe her pussy afterwards, but she remembers her past sexual encounters with her stepfather and squeezes his hard cock deep in her throat, even though she refuses with words. Her fingers unconsciously play with her pussy, and once her lewd switch is ignited, she can't stop the throbbing in her uterus by herself, and she is inseminated by her stepfather's cock for the first time in a long time.
