She didn't notice the way he stared at her while she stretched, but if she had, she would've blushed scarlet. She knew that he found her attractive, but she'd never been so...cat-like around him before. That was perhaps the best way to describe the way she stretched for him and it was a testament to how comfortable she'd gotten with him. No one else, not Ron or Viktor or Cormac, had ever made her feel so thoroughly appreciated and cared for, both physically and mentally. Severus appreciated every aspect of her, and she loved every moment of it. Hermione didn't ever want to leave, not if it meant leaving him.
She moaned at the feel of his hands along her sides and then on her hips. It was arousing and absolutely perfect, even if it wasn't in the position he'd imagined. She returned his smile with one of her own and kept her gaze on him as he positioned himself against her entrance. She gasped happily, the smile on her face never wavering, as the head of his cock slipped inside her. She felt as though he might split her in two but she relished it at the same time. She certainly wasn't yelping or crying this time.
"Severus," she moaned softly, her eyes closing as he pushed back in again, this time just an inch more before he pulled out again. Inch by glorious inch, they worked to slide him inside her. Her hips moved as well, helping to take more of him at first to indicate that she wanted more, that she could take more.
