She lay beneath him, a finger deep in her pussy, another hooked around the chain between the nipple clamps, pulling on them, her tits pulled and distended from her body, knowing how much he loved the sight of it. She was performing for him.
He stood on his knees, between her legs, stroking his cock as he watched her, a pearl of pre-cum dripping down the tip of his cockhead with languid slowness. He saw the look in her eyes. He was performing for her.
They were bound in an ever-tightening net of desire, she watching him, he watching her, each performing for the other. Each the sculptor, each the stone.
He reached down to slide two fingers deep inside her, moistening them, using her juices to lubricate his hand as he jerked off. She pulled more tightly on the chain, her nipples thickening, her skin reddening. She arched her back, her head lolling, exposing her neck for him. He knew she was about to cum; it spurred his own gathering orgasm. She cried out, her body corkscrewing beneath him. He moaned low as hot white plumes of cum spewed into the air, onto her belly, her tits, the sparkling metal clamps that held her nipples tightly entrapped, her body helplessly enraptured.
