My newly acquired adult stepsisters share an extremely warped relationship. The dominant older one treats the timid younger one like a toy, and the younger obeys her every command. The older stepsister is insatiably horny, while the younger was supposedly a serious honor student until her training turned her into an intensely sexual submissive. They force me to satisfy them both, worsening their twisted bond. Handling a sadist and a masochist at the same time pushes my mind and body toward collapse—and leaves my cock brutally overworked.
