Due to family circumstances, I ended up sharing a room with my sister-in-law. One day, when his sister-in-law fell asleep, I was secretly watching an AV, but my sister-in-law found me! Of course, I was also seen to be shiko! However, her sister-in-law peeked into the AV and my masturbation and started masturbating secretly, and furthermore, ``I can't stand it, I can't help it...'' Masturbation is not enough and I've been greedy for my cock! I got to see the worst disgrace of my life, but instead I got to have sex with his stepsister!
