He opened the door to his room and pulled her in, locking it and casting a Silencing spell before turning back to her.
She stood in front of the large window, arms wrapped around herself, in a fluttery white top and denim cutoff shorts. Her hair was wild around her face, her feet bare and curling into the carpet. And for a moment, he couldn't breathe.
Hermione took a half-step toward him, her breath caught in her throat and dropping her arms to her sides. He came to and closed the distance between them, wrapping his large hands beneath her ears, along her jawbone, and tilting her face up. Her arms came up and ran along his ribs, before tightening on his hips and pulling him closer. He kissed her then, wrapping his arms around her and pulling her closer.
They made it to the bed, getting tangled in the blanket before Severus yanked it off the bed and threw it across the room. She giggled then, and some of the tension was gone, and he smiled back as he leant back over her.
And her fingers clutched the sheets as he touched her, lower and lower and then there. He pressed closer, and she ran her hands down his back.
He moved over her, and pressed himself into her, feeling her tightness, and she let out a soft moan that would have finished him if he hadn't been concentrating. He couldn't stop a low growl from leaving his throat, and couldn't stop his mouth from biting her neck, then her collarbone, marking her harshly, for his own. He straightened his arms, pushing himself away from her, so he could watch her. He thrust forward, studying her face, her mouth. He drove into her again, appreciating the way her breasts bounced with every thrust. Her hands scraped red lines down his sides, and he almost came undone when she whispered his name.
"Severus," she breathed.
He stopped, nervous, but she dug her short nails into his shoulders again.
"Yes?" he asked edgily, but she just opened her eyes and looked at him, a smile spreading across her face.
"Harder," she whispered, her voice ragged. He half-laughed, and ran a hand along her inner thigh, supporting himself with his other hand. Then suddenly, he hooked her knee over his elbow and slammed into her. She shrieked, and he almost stopped again, but her nails scraped his chest warningly.
And there wasn't much more hesitation after that.
