Makoto-chan claimed she had never experienced an orgasm before, all because her boyfriend was premature and lacked skill in bed, leaving her unsatisfied. For this Katsuura sex retreat, a special plan was devised to focus entirely on bringing her to climax during every single session. Just like Coach Hongo rigorously trained Koayagi Koe, Makoto-chan would be mercilessly worked over to unlock her full potential. Her clitoris was carefully stimulated with a vibrator for over 30 minutes, then a bare penis was deeply inserted. The cock's head stretched open her vaginal entrance, aggressively pounding her cervix and G-spot. Ultimately, she achieved her first-ever orgasm, climaxing powerfully in doggystyle. Witnessing her trembling with joy, the coach realized, "Whether it's sex or volleyball, success depends entirely on the skill of the instructor."
