Riina who attends a welfare vocational school.Atmosphere that seems to be serious because it aims at the path of welfare.This time I came to study how to have sex, the appearance fee will be used for school expenses, and the number of experienced people is only one, so it seems that she is actually a pretty serious girl.In addition, it seems that there is also a dry side that utters the word "sex" even in the city without being embarrassed.The fact that the number of experienced people is small means that it is naive when it comes to sex.I think one of the highlights of this work is how much you can maintain your usual dry posture against forced leakage by electric massagers and handjobs that you probably have no experience with.Another highlight is H cup boobs. H, the size of the breasts that can be said to be a non-standard class numerically.Originally, it would have been nice to advertise at the beginning, but the reason why I didn't do it is because, unfortunately, it doesn't look that big at first glance, so I don't feel disappointment.However, when it comes to the actual performance, the H cup is at its best, and you can feel the power in the way it shakes.Please take a look at each of the highlights.
