Knowing that tomorrow will be Saturday and no one in the house would be looking for her before 10, she sets the timer for three hours and hit go. Brazzers Her legs are already starting to tire from their forced position, but even the slightest relaxation causes intense pain as the thin rope pulls steadily on her nipple clamps. The pain, torturous as it is, seems to accelerate the building climax. A slave that knows only how to feel. Next she sets the Master to shock for one second on her first orgasm, and one second for each successive climax. ‘Did the motors burn out?’ she wonders, but she knows the odds of both burning out at the same time were incredibly low. Her clit and rosebud are so sore from the constant barrage that the vibrators have lost their effect It had been nearly fifteen minutes since she has cum, the Master hit full power five minutes ago and it just isn’t enough anymore. For the last week Sandra has intentionally chosen tasks that require repeated stimulation right up to the edge of orgasm, but do not allow her to cum.
