Classmates who are popular gyaru girls suddenly invade the room of me, a virgin otaku with no social life, having heard rumors about my well-stocked manga and gaming collection, deciding to make my room their hangout spot. Though we normally never talk, something sparks them to visit that day. They relax in my room, playing games and reading manga, gradually letting their guard down. As natural physical reactions begin to emerge, the girls jokingly tease, "We'll let you use our cunts as a thank-you, so don't get in the way." Naturally, I lose my virginity—yet as they realize how much they're enjoying being fucked repeatedly, their inner females switch on like eager fish. What follows is an intense harem creampie session with aggressive, big-titted schoolgirls.
