My sister-in-law borrowed my old school jersey without asking and wore only sexy panties underneath! Seeing her like that brought back memories of my unrequited crushes from school days, making me horny as hell. I couldn't take it anymore and fucked her, creampieing inside her. At first, she was shocked, but soon she was moaning and cumming hard from my intense pounding. The combination of jersey and panties is too fucking hot!
