One day, my sister, who has beautiful legs, came out to me that she started working at a men's esthetic salon. She asked me to practice with her because she wanted to study. However, I didn't know it would be this risky! Her slender fingers brushed against my dick, and her long beautiful legs were tightly attached to my body. Her well-proportioned face was so close that I felt nervous. My underwear was about to tear from the full erection! When she practiced hard, her pussy touched the dick that had poked out from her underwear, and she inserted it raw... Once I fucked her, I couldn't stop myself from cumming inside! Sister and I had days of raw sex disguised as practice...
