Fantasy: I Have a Masturbation System

When I was a freshman in college, I unexpectedly got a masturbation system. With one stroke, you can get a divine state that lasts for half an hour. For physical tests, homework, and final exams, I often got into the toilet. My roommates were very curious about why I started drinking wolfberry soaked water. Of course we can't say this, because it's really hard to talk about. For a higher quality of life I started masturbating anytime and anywhere to squeeze out my life.
