HUNTA-032 "No, no! If I keep this up I'll end up in!" After six months of shut-in life, just as I was about to drop out of high school, my super nosy older sister, worried about me, forced her way into my room and cheered me up!!

It was supposed to be just intercrural sex, but it developed into serious penetration! My older sister, worried about me because I was a shut-in and about to drop out of high school, kept coming to my room, which was annoying, so I half-jokingly said, "I'll do whatever you say if you let me do it," and she agreed to intercrural sex! However, when my sister's pussy became slippery after being rubbed against her crotch, she accepted my dick, and it developed into incest!
