My brother-in-law Yuki, who’s new at his job, has to stay at my house for a while. As we start living together, I see my sister-in-law in her tank top and T-back, and I get all worked up! One day, while I’m napping, my sister-in-law’s T-back gets me so excited that I can’t resist attacking her. She resists at first, but her hips sway uncontrollably during my relentless thrusting, causing her to leak and climax.
