While my brother was away on his post, I visited my sister-in-law, Qihua, but on my way back, we were caught in a torrential downpour. The trams were out of service, so we had to stay overnight. Seeing my sister-in-law's soaking wet body, my lust overwhelmed me, and I finally crossed the line and had intercourse. In the hotel room, where we were alone, I couldn't resist and engaged in intense oral sex with her wet body in the bathroom. After showering, with her nipples erect and her hair still wet, we escalated our sex to intercourse. I had always secretly loved my sister-in-law, and I spent the entire night ejaculating inside her. Her large buttocks were sweating, and I thrust vigorously several times. Even on a sunny morning, we had wet intercourse again. That rain changed my world.
