My nurse sister worked 10 consecutive night shifts. When she came back, the abstinence was apparently too much for her, and she went crazy, forcing herself onto my dick regardless of whether it was mine or not! She transformed into a savage sex beast! My usually kind and serious sister didn't care about me at all, pushing me down and dragging me around, losing herself in fierce piston thrusts and coming over and over! Even when I said 'Wait a minute!' she forcefully sucked on my dick. There was nothing I could do to stop her until my sister came enough to be satisfied.
