[IENF-368] When I was playing a prank on my sleeping sister, she asked me to fuck her raw. I was about to cum, but she locked me in a crab hold and I couldn't escape, so I came inside her! 6 (Censored)

Even though we are brother and sister, I was so excited to see my sister so defenseless that I wondered if she was trying to seduce me! Even though I knew it was a lie, I just couldn't resist... What! Was she really inviting me? Before I knew it, she was asking me to do it, and I couldn't stop either... But it's dangerous! We're family after all! It's dangerous to cum inside! Crab-claw lock! ?
