A beautiful girl who seems to have little luck.She seems to say that she is a yin-kya in today's language.There is one such student in her class.Only for such a student, she has a disgusting body.Student Rika in my class.The body and proportions that are out of the world.The gap between her plain face and personality is irresistible.She has a narrow waist and big breasts that can be seen from the top of her uniform.A well-shaped and comfortable ass.Although she is a student, she is a woman who was born to have sex with a sex appeal that can not be produced even by adults.I made such a student a sex slave, and today I use her like a masturbator.
