He stepped back to admire his handiwork, reveling in the idea that she might finally be totally powerless to his considered touch. He had decided to place her face down on the bed, her arms resting limply in their bonds above her head, hair tumbling down her back. He had been careful not to entwine her hair in the knots, knowing he would need a fistful to pull later as he was finally able to slide his cock into her glistening cunt. Her legs were spread wide across the width of the bed and secured carefully, her mouth filled with her soaked knickers to ensure her protests wouldn't distract him from his only task of owning her completely.
He had considered restraining her facing upwards, ankles bound to thighs, knees spread wide so that he could clearly see her emerging wetness as he teased her mercilessly. He decided against this on the basis that his former position would allow him to fuck her with the full weight of his body on hers, her face pressed firmly into the pillow to serve as a constant reminder to the fact that she was merely there to be a receptacle in which to cum, then leave with his pleasure to glisten down her thighs unable to do anything but accept that he would only return when he next wanted to use her.
He smiled to himself at the thought that his prick teasing slut would finally be helpless to him; punishment for the previous weekend. He recollected with frustration her writhing at his hand tracing the base of her spine, the way she pushed her body into him then when he could finally feel the wetness of her through her pajamas, her making herself come and not allowing him to touch. His only relief had been to taste her fingers as he brought himself to climax.
