Potter turned his head to Draco again, and his eyes darkened. 'You're hardly in the position to tell me what to do, Malfoy.' He eyed the rim of his sombrero and picked another pink clamp, letting it close with a sharp snap. It sounded obscenely loud in the quiet forest. 'Look how pretty the pink looks on you. I think we should add some symmetry.' He gave a soft tug to the clamp already in place, then circled his fingers around Draco's other nipple, already hard with the cool night air and the adrenaline surging through his body. Potter rolled it between his fingertips, then pulled gently and placed the clamp around Draco's other nipple. He stepped back and looked at him, and Draco saw something ignite in those dark eyes.
