Wish there was more work with Climax Endurance. Watching a girl trying to resist having an orgasm is pretty hot, especially when the stakes are a lot higher. Even though the stakes aren't as high in this, and technically it's a "happy" ending, every time they pull out a new toy and have her getting worried is pretty good.

Scene skipping is pretty bad in this one though, there's 11 rounds, but each round only has about 6-8 pages of stuff. Would have preffered shorter rounds and longer content per round. 7/10. Hope this genre gets picked up by more authors since it managed to sell so well on Dlsite.
