|What I have learned from you, that is to be a bitch in ecstasy...
Sister, we can teach you some things, too.
Yuki, a tutor whom the three college students, Ryo, Ri and Koji, have been continuing their banned relationship. Then, Yuki's classmate, Yamato asked her out on a date. Ryo found this out and stated the following condition. That was to go out on the date with a vibe strapped in to her. Also, she must hold in her urge to come more than 3 times or else the condition will continue... The movie theater, the restaurant's restroom, and the ferris wheel at the amusement park? The 3 college students continue with their scheme... Then, there's Yamamoto, who knows nothing of what's going on and only enjoys the time spent with Yuki. The vibe jammed up her secret spot, the bead vibe in her anal spot... and the taste of come in her mouth... Her love juice slowly dripping...Yuki tries very hard to hold it in... If she doesn't hold it in now, it will only continue... But will she be able to withstand it...?
