He looked down at his work and smirked. They were both naked, and she was on all fours on the floor, a pillow under her knees, blindfolded and wrists cuffed together. All in all, a very appealing picture, he thought to himself as he slowly circled her. She was breathing heavily, so wet it nearly dripped down her leg from earlier when he had stood behind her in this position and fingered her. He hadn't let her orgasm, but at least she was plenty warmed up. Finally, he stopped in front of her, tracing the tip of his cock across her lips. She darted her tongue out and shifted forward, trying to engulf him, but he stepped back, leaving her to whimper disappointedly.
"Please..."
"Please what?" He asked, grinning.
"Anything, god, please anything, just do something to me..."
He chuckled and nodded, moving around behind her and resting his hands on her hips. Once he was in position he thrust in quickly, making them both moan loudly at the entrance. Her head leaned back in pleasure, and he reached forward to hold her hair, pulling out slowly before thrusting back in hard.
"Oh, god..." she groaned, almost dipping her head instinctively, which only led to more of a grip on her hair.
He continued thrusting, only making it through a couple more slow ones before it was just too much. He sped up, pounding her fast, savagely, mumbling under his breath "god yes... oh, yes... fuck fuck..." Her words, meanwhile, were soon indistinguishable, a rapid stream of babble. Had he been in another state of mind, he might have forced her to beg for him, but they were both too far gone for that at this point.
After an especially hard thrust and a slight tug on her scalp, she came loudly, moaning "god yes yesyesyesyes..." She loosened under him, but he wasn't done yet. He released her hair, her head dropping in exhaustion, and grabbed both her hips, slamming into her body, pulling her back onto him with every thrust. Now that she was done, he was entirely focused on his own enjoyment. It wasn't too much longer when he came, filling her with a moan, almost a growl. He thrust throughout his orgasm before stopping, relaxing slightly, and kissing the small of her back as he pulled out. She sighed when he did so, and he moved to unlock her cuffs, lying on the floor. She curled up next to him with a contented sigh, before saying quizzically "blindfold?"
