During my brother's business trip, I visited my sister-in-law ayaka but got caught in a heavy rainstorm on the way back. The trains stopped, forcing me to stay overnight. My lust raged seeing her wet body, leading to intense creampie sex. In the hotel, I couldn't hold back. We had passionate oral sex in the bath, and after bathing, her slippery nipples and wet hair drove me wild. All night, I poured everything into ayaka, who I had secretly admired. Her sweaty big ass took my hard thrusts. Even in the morning, after the rain, we had messy sex. That rain changed my world forever.
