Then his weight slightly and she cried out - a tug at the leash put unbelievable sensation through her already sensitised nipples and clit, nearly causing her to drop the chain. She felt his hands massaging her breasts firmly and whimpered as she realised he must have taken the leash in his mouth. She felt his lips and tongue, soothing, tantalising, around her collar, along her neck, and then it was gone and another tug to the leash and she cried out, teeth clamped across the chain. This was harder, and had caused her head to pull up, yanking painfully at the nipples. He played with her breasts leisurely, every squirm of her hips forcing her to grind against the hard pressure of his knee. She knew, instinctively, that he was going to keep this up until she failed. She was afraid of the pain that would come with removing the clamps, but she didn’t know how much longer she could last. Maybe it would be better to give in?
