I got it! A perfect idea for a squeal. Ren's parents go out of town for the weekend for a business meeting and have Kei babysit in exchange for not having to pay rent that month. While he's watching her she shows him her new wrestling out fit that she made (it;s super revealing) and she wants him to "play" with her like he did here. More role-playing fun is had by all and Kei gets away with it :D

This is so awesome. I so want there to be a sequel

Today marks the 10th anniversary of this doujin. Happy 10th, and I'm still hoping for a sequel one day lol :D
