My Slutty Younger Step-Sister, Drenched In Sweat, Won't Stop Clinging And Grinding On Me Even Though I've Already Cum - Mia Nanasawa

It was a sweltering hot summer day. My sister Mia and I were home alone with our parents away. The air conditioner broke, and the humid room made us wear loose clothes, our skin damp and sticky. I gave in to innocent Mia's temptation as she showed off her breasts, wanting attention, and we had our first sex, soaked in sweat and bodily fluids. We did pervy things in the bath, the hallway, the kitchen—blowjobs, fingering, all sweaty and dirty. Blaming it all on the heat, I kept thrusting into her little ass over and over... summer memories with my little sister.
