This Summer, as a high school student, I had cut off all my desires. However, one day, I couldn't help but masturbate because of my sister's alluring, sweaty sleeping posture! Her slender, 8-head body and model-like beauty were irresistible...
"What are you doing? You said you were practicing abstinence, but you're still a guy after all, aren't you?"
When I'm held close to her sweaty, lustful body, my head spins and I can't resist. Her leg techniques, like a snake slithering towards my erogenous zone, reset my abstinence over and over again. The relentless pursuit makes me cum uncontrollably, then I get scolded and made to cum again. I don't care about exams anymore. I just want to be teased by my sister like this forever...
