Hit and run.

*TW: descriptions of sexual themes.

                               What seemed like hours went by where the both of you simply sat in deafening silence, aside from the soft rustling of parchment and the scribbling of a quill. His frame was warm against your own, his chest flush to the surface of your back. You could feel each breath he took and the steady rhythm of his heart, which seemed to beat in time with your own. Occasionally you'd give a little wiggle of your hips, stirring up a low grumble or clear of his throat in response.

You were still sat within his lap, over the thickness of his thigh as your fingertips danced along the edge of the desk. Every so often you'd point out a mistake in another students work and Severus would flash a lift of his brow, mark it, and move on. You knew he was definitely attempting to keep himself composed. Having you on his lap was something he wasn't really used to — it felt intimate in a very different sort of way than things have been before.

You felt yourself growing extremely bored after a while. He hadn't been lying about having a lot of papers to grade. Giving another wiggle of your hips, you moved slower this time. Meticulous with the way you swiveled yourself over his knee. Severus stiffened beneath you and you noticed his fingers grip the quill just a little bit tighter. It was wild to you, that you were able to affect him so easily and that only seemed to egg you on further.

Slowly, you started to grind against the smooth material of his fitted pants. He immediately shot you a curious look from his peripheral vision, eyes narrowed and lips pursed. He tried to come across as angry, threatening, as he slowly sat his quill down but you knew he was merely starting to lose grip of his resolve. You knew an aroused Severus Snape when you saw him.

Neither of you really spoke about emotions or feelings with one another. At least not openly. It wasn't easy to break through the million different walls he had built up to protect himself from the outside world and everyone else in it. In a way, you related to that. You were afraid to let people in, see you and get to know you. It wasn't that you particularly hated other people, more so that you were scared of not being enough. Of being another disappointment to them.

Her hands gripped the edge of the desk as you worked your hips slowly over his knee, toes curling within your boots as a tiny little moan slipped past your parted lips. That was more than enough to cause Severus to reach out and grasp your thigh between his fingers, squeezing rather harshly. A warning.

"Sit...still," he breathed in a low and guttural tone.

You stilled, just as he commanded you to. But only for a few moments. Long enough for him to pick up his quill and resume reading over students' essays. Your eyes scanned the desk and reached out with a curious hand, gripping one of the tiny potion bottles that sat near the front towards the edge.

Severus stole a sideways glance at you, but did not stop. Not yet. You traced the outline of the little glass bottle until your fingertips reached the top, popping it open. A tiny puff of smoke billowed from the opening and he immediately snatched the potion from your hands, placing it back in its original spot.

"Don't meddle with what isn't yours, y/n."

Your lips slowly curled up into a knowing smirk, placing your hands into your lap. But they didn't stay there for very long. Slowly, you inched your fingertips from the hem of your sweater to the softness of his thigh. Higher and higher until you paused just before the area of his crotch.

You knew you were misbehaving. You knew you shouldn't be doing this. Yet here you were, sat within his lap and practically palming him through his trousers. Sex was the way you two seemed to communicate. Words weren't always required and you both always seemed to be on the same page. It was easy. Opening up and letting him in on your deepest fears, regrets, worries. That's what scared you the most. And you were almost certain he felt the very same way.
