After my mother passed away when I was young, I looked up to my older sister who had been like a mother to me. A month after she got married and moved out, she suddenly came back home! I couldn't ask why, but one day, my tipsy sister asked me to try something, saying it was because of her husband's sex. She couldn't explain what was wrong, so I agreed. This is how our incestuous relationship began, but I was shocked by my sister's unique fetish. "Come on, savor it more," she said. The birth of the ultimate "anal creampie sister-brother" duo!
