Minori Kawanami is a sweet, diligent maid with a strong desire to serve. To help her young master overcome premature ejaculation, she begins training him through repeated orgasm denial. However, clumsy and unable to gauge his limits, she ends up making him climax even faster. What starts as practice escalates into intense sessions involving blowjob techniques, handjob training with a fleshlight, and even restrained hardcore drills. Rather than improving his condition, the training only ensures quicker, more explosive ejaculations—often drenching her in his load. Experience the erotic chaos of a naturally lustful maid who leaves her master completely drained.
