IENE-763 - Teasing my sleeping stepsister went wrong: Forced into raw sex with a leg-lock trap

I tried to prank my defenseless sleeping stepsister, but she woke up and immediately assaulted me with a deep kiss. She started sucking me off, and things escalated way too fast. I couldn't hold back and went for raw penetration, but when I tried to pull out before cumming, she locked her legs around me, trapping me in a tight squeeze. No escape, just forced internal ejaculation.
