"There you go- soaking wet and quiet. I might even get used to your company if this is how it goes every time." He grunted and knocked her into the desk again. "Fuck girl, you’re making a puddle on my desk. What a messy slut." His cock dragged along her inner walls at a brutal pace, stretching and receding and stretching again. Pleasure blossomed inside her and like the plants in Herbology it had its own mind. Tendrils grew and spread, filling her belly with pressure, more and more, reaching all the way to the muscles in her thighs and lower back, causing them to tense and twitch and scream. Her whole body was screaming. Screaming for more, more Snape’s cock, for his touch, for release and  more . Always more.
