While my brother was working away from home, I visited my sister-in-law, Ayaka, but was caught in a heavy rain on the way home. The trains weren't running so I was forced to stay the night. My libido ran wild as I saw my sister-in-law's wet body, and I crossed the line into creampie sex. There was no way I could hold myself back when we were alone in the hotel, so I gave her a deep blowjob while still wet in the bath. Her nipples were showing after the bath and her hair was wet, and our creampie sex escalated. I poured everything I had into Ayaka, the woman I had secretly admired, all night long. I pounded her sweaty big ass hard over and over again. Even on a sunny morning we had a sloppy fuck. That rain changed my world forever.
