Demon Rape: The Semen Collector

A twin-tailed schoolgirl in a sailor uniform walks with her new boyfriend in a park on their first day of dating, invites him to stay overnight because her family is away, then enters a public restroom. There she presents a jar of male semen stored in her body to a one-eyed tentacle slime demon (a demon-realm semen merchant) that emerges from the toilet. A flashback shows the demon previously attacked her in that stall, bound her with tentacles, and hypnotized her with a beam from its eye into an obedient slave ordered to seduce men and collect their semen. The demon extracts a full jar from her vagina, rewards her with aphrodisiac and deep multi-penetration of vagina and anus, fills her with secretions, and implants demon eggs into her uterus for incubation. Ordered to return every two days with a full load or lose the hypnosis, she redresses, steers another woman away from the stall, and rejoins her sweaty boyfriend to take him home immediately for further collection.
