Seeing my little sister's defenseless sleeping figure in her all-girls school uniform, I couldn't help but feel like playing a prank. So, I secretly sexually harassed my sister. As she woke up, perhaps aroused by my prank, she counterattacked and inserted herself into me raw! She started moving her hips vigorously, and when I was about to climax, she locked me in place with her legs in a crab hold, not letting me escape!!
