This summer, I swore off every pleasure to focus on retaking my entrance exams—until the sight of my gorgeous, sweat-soaked older sister asleep made me masturbate. She mocks my failed abstinence, pins me against her steamy body, and works my sensitive spots with her legs until I cannot resist. Even after I cum, she keeps chasing one orgasm after another, making me squirt and ejaculate 11 times. By the end, I no longer care about the exam; I just want her to keep dominating me forever.
