Yumi is a school counselor who listens to students' concerns and consults at schools. Students who are sensitive and have a strong interest in sexuality. It seems that students who have excess sexual desire that can not be dissipated well often come to ask such as "Please tell me how to etch" "Because I masturbate, please do something exciting". He is a counselor who loves all the students from the bottom of his heart, is enthusiastic and kind, and teaches such students gently about sex and sometimes foreplay. Perhaps because I often get on such naughty consultations, the technique to excite a man is more than average. If you squirm your nasty flesh and say "more impatient ..." with a sweet voice, most men wouldn't rush your crotch to mess with this guy. Is it? In response to Yumi's luster, we will do our best to meet you. I will give her a professional technique to make her happy, who is usually dealing with awkward students in Ubu.
