Today's visitor is Marina-chan, 23 years old, a current university student. Marina-chan loves math and is a hard worker who even took a year off to get into a certain science university. She is a bright and cute girl with fair skin and long black hair. She has a good figure and long legs, and is an athletic girl who played basketball until high school. Now she is in a puzzle solving club at university, and on her days off, she goes to play puzzle solving games around town. She is laughing as she talks to me, but she seems to be really nervous. I started by kissing her, and Marina-chan entangled my tongue, and she was in full erotic mode right away! Where did all the nervousness go? Just a little touch on her chest made her tremble with sensitivity, and her excitement level reached its maximum! You must also see her erotic hips that sway as they suck the dick dry! I returned the favor with a hard thrust, but Marina-chan was better at it.
