The serious and cute class representative, Riku, was the girl of my dreams. One day, I followed her suspicious movements and peeked into the gym storage room, only to see her bound in ropes, blissfully spreading her legs—a truly lewd sight. Realizing she is a masochistic meat toilet who thrives on bondage and training, I couldn't help but get an erection. Witness the secret shibari sessions happening right under the school's nose as she eventually seduces me into her world of shame and exhibitionist pleasure.
