Tied and tickled (Pixiv Fanbox)

This trainee is right in the midst of a cruel game~ Her trainer tied her up and made a deal with her. If she manages to hold her laugh in for only 5 minutes, the session will be over and she’ll get to rest for the remainder of the day. If however, she fails to complete this task, she’ll be stuck tied up and tickled until her trainer grows bored of it. Only 20 seconds have passed so far and she’s already at her breaking point~ It’s funny how games like these can feel like an eternity. Do you think she can make it?
