Mio Futaba is a gentle older sister who works in the medical field.When I saw the scene where she was being interviewed, I thought she was a quiet woman, but the reason she appeared was that she was often interested in watching AV, which was an unexpected reason.By the time she started to get a little tired of normal sex with her boyfriend...Perhaps because she works in the medical field, she has a disgusting feeling that sex is like palpation while watching a man's reaction.When she touches a man's crotch with his hand, when a man feels it with a nipple licking handjob, her smile makes me feel wonderfully erotic.On the contrary, she is aggressive even when she is blamed, and she also has a lasciviousness that makes her waist sit on her face.She seems to be playing an obscene doctor, and it makes me shudder.She is positive and wonderful in the woman on top posture that jumps on the male genitalia.When it comes to sex, a woman who seems to be mature smiles and becomes aggressive.
