MIDA-235 My best friend’s older sister found out about my quick climax and endless stamina, and during just a three-day overnight stay, I was kept on edge and teased nonstop… Unpai

Three days staying at my best friend’s house. As I was teased by my best friend’s older sister, who kept getting unusually close to me and is apparently called Unpai, I unexpectedly lost control. Even after that, I still couldn’t calm down, and she found out I was quick to climax and had impressive stamina. Before long, I was treated like a toy. Whenever she got the chance, she would tease me and keep me on edge, making me release again and again. [Intimate moments near my sleeping friend, a surprise encounter in the bathroom, being caught in the hallway, and a secret moment during breakfast] I was played with everywhere, all the time, until I reached 30 releases. I can’t… I can’t anymore…
