A/N: SPOV
Severus had hoped that she would simply go away, not put herself further into his mercy.
"Occlumency can be achieved using the same principles that I had shown you; it requires a clear mind that has organized and filed away your memories and other stressors out from your visible reach. However, you would need to practice with someone performing Legilimency and attempting to breach your mind as you parried their attacks or gave up half-truths in order to convince them of achieving what would essentially be a false victory."
He stepped into her now, his lips nearly brushing her ear. Perhaps I can scare her off from that offer I made with a brutal half-truth. He thought as he summoned all of his courage and imposed himself upon her.
"As for the other types of training, Nymphadora, I sincerely suggest that you not pursue that avenue with me. It was a most prurient offer that I should have never made to you."
He let his fingers slip through her hair ever so lightly, but clamped down as his cheek was grazing hers, pulling her head back enough to hear her gasp in surprise.
"I am a man who has learned how to mix pleasure and pain to become something that most people never get to experience, and it would be a shame to whet your desire for something so dark only to leave you feeling so unfulfilled with mundane lovers." As he said this to her, his lips were millimeters from grazing hers, and the only restraint he had from forcing his lips upon hers was the growing arousal in his pants, threatening to be noticed by her if he remained this close to her.
He let go and backed off to a suitable distance from her. His mind seemed more clear now, though his body ached for the closeness that it had recently enjoyed. "And as much as I might enjoy having you collared and at my feet, begging for me to give you sexual release, I doubt that Remus would approve of such an... unconventional arrangement."
Severus needed to get out of the room. Bugger, I need to get out of the bloody castle. As he slammed his door open and left his office, he didn't care that he had left her in his personal quarters, inside all of the defensive and privacy charms that he had normally kept up to dissuade a wandering eye.
Perhaps if she sees my toy drawer, then she will run away and not seek to speak to me at all whatsoever. He thought darkly, considering his collection of flogs, whips, blindfolds, and restraints.
Severus left the castle and marched towards the lake, only stopping until he reached the tree that was the center of his own mental visualization of a calming place. Let her see and understand the worst of me, he said as a profane prayer, so I don't have to deal with her anymore.
