VEC-135 Mother's best friend Ruri Saijo

Ruri is entrusted with looking after the c** and staying at home while her friend and her husband go on a trip. - I found a pink rotor that seemed to belong to a friend. - Unable to suppress her desire due to the excitement and sense of immorality of seeing something she shouldn't have seen, Ruri instinctively puts it on her crotch. - Then, the c** who was peeking at the whole story... - The boy's lust for the lewd appearance of a woman he sees for the first time does not stop him, and he begs Ruri to teach him.
