"I understand, Master," she murmured. She groaned as the moist heat of his lips encircled one nipple, teasing, his tongue flicking across it before he sucked lightly and then withdrew, blowing on the sensitive flesh and causing her to whimper as the bud tightened. She felt the pinch of rubber tightening against the nipple, making her wince as he tightened it further. When he was done, he licked the clamped nipple and she shuddered at the delightful sensation of his tongue against the tortured bundle of nerves. He repeated the process on the other side and when he was done, she was shaking lightly. She wanted him to touch her. She wanted the clamps gone. Oh, but no, she wanted him to lick her again while they were there. Or maybe pull at the chain to see what that felt like. Fuck, her core clenched at the conflicting desires and she moaned in frustration.
