The moan that escaped her lips seemed loud to her ears, and yet rapidly eclipsed by the delightful smack of skin on skin as his hips snapped against her. With a start, she realised that the motion was going to cause her to swing away, but then his hands were at her hips, pulling her back to him and burying himself to the hilt inside of her again.  The room, the audience, everything disappeared as her focus narrowed to the sensation of him sliding into her, the chain at her clit and nipples tugging with every thrust. Her jaw fell open and she moaned, panting in time with his movements. It was agony and bliss all at once - torturous pleasure, and she couldn’t get enough. What little brainpower she had remaining was cheering and sobbing in bliss at having found this. At having found Snape.  She wasn’t aware of how long she remained on the precipice before she was gasping, shuddering, spasming around him. With a cry of astonishment and gratitude, she felt her awareness slipping away just as his fingers pressed firmly into her, the staccato beat of his hips against hers betraying his own completion just moments behind hers.
