"I asked you. What are you?"
"YOUR SLUT" she said it clearly and firmly this time.
"And what do sluts do?"
"Only what they are told. I am here to be used by YOU."
"Good, you do know. Don't forget." He punctuated his last admonishment by slapping her across the face with his dick. Then he let it lay against her lips, he was testing her. Whether it was a moment or an hour she couldn't tell but it felt like an eternity waiting for what she wanted.
Then it happened just the way she craved it. He pushed her chin down opening her mouth and his cock fell into her longing mouth. She could taste the precum. It was then she realized he hadn't let go of her hair. She quickly relaxed her throat and jaw, but not before, he crammed his dick all the way to the back of her mouth, past her tongue, to her throat. She gagged, but at least she didn't vomit, she swore never to do that again.
The head of his dick was at the soft opening of her throat; her lips were stretched around the base as his balls swung against her chin. She squeezed the muscles of her throat around his head trying to pull it deeper. Her cunt was on fire, begging for any type of attention it might get. He pushed her farther down him, forcing her nose into contact with his belly. The salvia in her mouth had no where to go and was building up, she pushed down harder on him just to get an excuse to open her mouth and let some run down her chin for relief. Then it started his head started pulsing and his hip started gyrating. He was going to cum soon, very soon.
He dropped one hand down to touch the side of her tit and began to draw circles with his fingers. Almost immediately, her pussy started to gush and she to moan, neither one of them knew why nor how he could make her cum by touching her there but he had done it since the beginning. The he became more excited with the sounds of her pleasure. His fingers found her nipple, hard and swollen, and he began to squeeze it between his thumb and knuckle. It hurt so damn good. He squeezed harder still, she felt the pain transition from pain to pleasure. The pleasure of his touch, him using her, and making her feel. She started to cum again.
"Look at ME" he demanded. She forced her eyes up to do as he instructed as he jammed his cock in and out of her mouth harder and harder, her eyes welled up as he kept using her. She felt the hard tiles of the shower wall press against the back of her head as he drove his cock deepr into her. Then his cum launched out into her throat and mouth, he shuddered and gasped as orgasm wracked his body.
She knew then, on her knees, nipple aching, jaw stretched to it limits, eyes lifted up to look on him, why, why she love to be His Slut. It gave her control. Control when he was most vulnerable. She had gained control by her submission.
