Riko Matsuzaka is 28 years old and teaches music at a school. I'm sure there are many male students who are tormented by the prospect of such a gentle and lovely woman as their teacher. Riko seemed very nervous at the beginning of the shoot. Apparently, she hadn't had much sexual compatibility with her previous partners, and that this had led to some breakups. Although she applied for the role because she wanted to have pleasurable sex, she likely had some insecurities. To ease Riko's nervousness and anxiety, the actor first brought out a small vibrator. He ripped her black stockings and stimulated her. Perhaps her tension was relieved after a brief orgasm, as Riko gradually became bolder. With a larger vibrator than before, she became so wet that she made a lewd, squishy sound, and squirted on the actor's fingers. She gave him a blowjob, making slurping sounds, and looked at him with lustful eyes, seductively. When he placed his penis between her breasts, she smiled with delight at its hardness. She was wearing her torn stockings and her underwear was pushed aside and he penetrated her, creating a very obscene scene. Her breasts swaying wildly with each thrust and her satisfied smile were very impressive.
