I'm such a sweet woman, constantly looking out for you while pushing your boundaries and respecting your limits. But I have a very strong sadistic side, a natural mean girl inside me. I love imagining you in pain, beating your balls over and over at my command. We're playing a game. Stroke that cock furiously with lube, then stop and smack those balls hard as I instruct. Obey like the eager pain slut you are. Pump desperately for my body, endure for me, then cum hard and drain those aching balls.
