[Sakino Yumeko] Sperm At Work (Cells At Work)

A seasoned white blood cell finally corners the shy red blood cell rookie she's always found cute, teasing that she's noticed his wandering eyes long before pinning him beneath her overwhelming curves. What starts as banter about his kouhais' teasing melts into a relentless titfuck and cowgirl ride where she demands he give it all he's got—and even after he empties himself inside her, she's nowhere near done. U-1196 runs the entire show in this sweat-soaked femdom turnabout where the hunter turns out to be the hunted.
