Don’t drop it (Pixiv Fanbox)

This trainee has been suspended with ropes. She’s been told that there won’t be any rules regarding her pleasure. During this session she can go wild and reach as many climaxes as she wants~ There’s just one little catch: She’s not allowed to let the pre-lubed toy inside her fall to the ground. If the toy slides out, she fails the session and will be punished~ Of course, her trainer is making it as difficult as possible for her by tickling and teasing her body. The more she squirms and flails around, the more likely it is for the toy to slip out~ What a cruel training method, right?
