Rima, a transfer student from Kansai with a strong sense of justice, implements after-school special training blowjobs to save Naoki and his perverted cock! "You want to get back at them, right? I'll teach you how to use your cock!" Despite the amazing blowjob, he ejaculates prematurely. "You have to try harder!" she continues with a cleanup blowjob. After more endurance training with encouraging blowjobs, Naoki successfully improves his cock and makes Rima cum repeatedly with his grown cock!
