Being pretty, Nanako Takeuchi has many opportunities to get fucked and satisfied. One of her students likes her a lot and he is often having fantasies about her. One day she met him out of his house and he asked her to teach him something about sex, as well, because he does not know anything about it. She decided to do it, since she really liked him, so soon she was moaning from pleasure, surprised with how fast he was learning very important details about satisfying women. It looks like they were both enjoying more than they expected it, while they were fucking, so in the end of the session, he came into her mouth and had a real blast with it.
