Bouncy G-cup Hiiragi Rui has only ever slept with one person, and now she is made to cum over and over. The inexperienced 19-year-old undergoes sensitivity testing and erotic training, followed by deep tongue kissing and relentless pounding, bondage and toy play that keeps her climaxing, titjobs and blowjobs, a sexy maid scene with a huge cock, and a sweat-soaked threesome with nonstop thrusting. Across three sex scenes, her orgasm-sensitive pussy is pounded without mercy, and they keep going even after she convulses through massive, juice-soaked climaxes.
