FSDSS-475 3 points on the test! Full marks for sex! I was supposed to be teaching my cousin who has big breasts, but instead she taught me how to have sex and it was too hot...Summer! Momojiri Kaname

One summer day, my cousin came to visit my parents in the countryside. My cousin is not good at studying, so I decided to teach her... Her breasts are big... When I was curious about my cousin's breasts, she said, ``You're a virgin, aren't you?'' I couldn't respond to her sudden words... After this, my cousin said... Happy days were waiting for her when she was seduced by her big breasts, fucked in cowgirl position, and fucked hard...
