While working as a tutor for a living, Ririka, who is actually a genuine masochist to the extent that she gets stuck, regularly goes to the trainer.

When she is tied up with a hemp rope, she repeatedly squirts due to climax, and she has an ecstatic expression on her rope scar that remains clearly.
