Tied to a chair, her arms pulled back behind her, feet and legs immobilized, Mercy waits. A large vibrator tied into her pussy complete her helplessness. She is aware that her up-thrust breasts and large pink nipples are an easy target for her Master's attentions. Her anticipation is soon resolved when the clamps are squeezed upon her nipples and the nearly unbearably burning sensation. When the stretcher bar is attached, tears well up in her eyes as her tortured nipples are squeezed and pulled. But she can only whimper through the ball gag and hope he will soon release her.
