There's times that I forget that I'm a sadist. That I love inflicting pain on a willing partner. Rosie is a masochist, she loves pain. Curled up on the sofa, I start slapping and squeezing her tits, adding pegs, and then getting her to choose the final toy I use on her, while she uses her vibrator. When the pain stops, it doesn't take her long to reach a powerful orgasm.
