It's common to watch AVs and think, "Huh? With such a cute face, she's incredibly horny!" Today's girl, Sanae, is a perfect example. She looks slightly younger than her twenty years, appearing inexperienced at first glance. But once you talk to her, she surprises you with how erotic she actually is, completely defying first impressions. She's a student, usually short on money, so maybe that's why she agreed to participate in this amateur filming. Her current boyfriend is a salaryman she's been dating for three months, having met at a mixer. He probably fell for her bright and honest personality. Plus, she's very open about sex, making her boyfriend seem incredibly lucky. They apparently have great sexual chemistry, but Sanae has a passionate yet fickle nature, which might leave her boyfriend confused. Despite being in a relationship, she still contacts her ex-boyfriend, and on days they meet, they even have sex—showing her true colors as quite the bad girl. What a naughty girl, seriously (laughs). When asked about her sexual preferences, she claims, "I'm pretty normal." But that sounded suspicious, so we pressed further. Turns out, regular sex sometimes isn't enough, so she asks her boyfriend to tie her up or use toys. This is way beyond what we expected. She also admits to masturbating regularly, using both vibrators and electric massagers. When we asked her to demonstrate, she readily agreed, spreading her legs on the sofa and placing the vibrator on her pussy, while using her other hand to fondle her breasts. Before we knew it, she was moaning and said, "I came (laughs)." So fast! And she didn't even realize she'd climaxed. So this time, we handed her the electric massager and asked her to go again. And wouldn't you know it, she came even faster! Unable to resist any longer, we got our dick hard. The contrast between her innocent eyes and her true erotic nature was just too much to handle.
