Tight Binding Wish, Ayuna Koi

Ayuna, a high school girl who harbors intense fantasies, longs to be thoroughly disciplined. Bound tightly with cords, her strong desires are awakened. The more she's tied up, the more aroused she becomes—a true masochist. Once restrained with rope and spanking, she's brought to the brink of ecstasy. When penetration reaches her womb, she screams in overwhelming orgasm!
