That day, the weather was beautiful when a sudden rain poured down, causing Akari Asakiri - my mother's close friend to get soaked and had to knock on the door to seek shelter. I was very worried and immediately ran to get a towel to dry her body. She casually took off her dress, leaving only her underwear, and dried herself in front of me. I must say that even though she is almost 40, she still looks very attractive, with big round breasts and a curvy butt that made me very excited. I was so absorbed in admiring Asakiri that I didn't realize my penis had become erect at some point. Sensing this, she took the initiative to help me relieve my desire with her years of sexual experience. I silently thanked the sudden rain outside for giving me the opportunity to have sex with this lustful friend of my mother.
