Hina Serizawa possessed a unique sensitivity—right after losing her virginity, she discovered anal sex felt better than regular intercourse. Under the control of dominatrix Kanazuki Rami, Hina's anus is meticulously stretched using an array of brutal anal expansion tools. The process, though painful, overflows with pleasure, and Hina gradually surrenders herself to the sensation. Finally, the long-awaited intense anal sex with the queen begins. The strapon presses deep into Hina's rectum, tightly clinging and thrusting deeper with each motion. Hina had always emphasized that she could only reach orgasm through anal sex, but this experience felt entirely different—her body reacting to the queen's skillful hip movements, she eventually climaxed completely.
