At the 'J◯ Observation Club' where you can observe high school girls (Yukine Sakuragi, Yukari Miyazawa, Erika Saeki) masturbating through a one-way mirror, if you pay an additional fee, the hole in the mirror opens and you can play with their breasts and pussies. Not only can you give me a blowjob, but if you pay extra, you can even have raw sex
