The shy, geeky childhood friend who, once she discovered the pleasure of sex, started riding me cowgirl style and squeezing out my sperm everywhere - Sumire Kuramoto
Shy and plain Sumire is a geeky girl obsessed with erotic novels, secretly masturbating in the classroom. One day, her childhood friend Tatsuya, who's barely passing, asks her to deliver his homework to his house. He acts as usual, making it seem like just a simple errand—but that day, he has a full morning erection. Curious about seeing a man's penis for the first time, Sumire can't resist and impulsively inserts it bare into her pussy. Overwhelmed by the intense pleasure of her first time, she becomes addicted to Tatsuya's hard cock, and from that day on, she craves sex uncontrollably, seeking opportunities to drain his sperm wherever she can. In the living room, she wiggles her perky ass and rides him hard in cowgirl position, taking creampie after creampie. Even with friends around, she secretly jerks him off in class until he erupts. In the infirmary, she keeps him inside, demanding creampie after creampie until he cums five times. Sex feels this amazing? This is the best!
