Orgasm: Mariko

It's nighttime at the beach, and a young couple is frolicking on the beach under the moonlight. The girl's name is Mariko Kamura, and she and her boyfriend Yukio have forgiven each other for everything. Mariko is about to start her period and Yukio forcefully starts to feed her. The two of them climaxed and were gasping for air. At that moment thrusting of her hips from behind stopped and she stopped moving. Yukio's face was pale and flushed and a streak of blood was running down his forehead.
