Her day had been going well; her projects were on schedule (or, honestly, well ahead of schedule in many cases) and her coworkers were in good moods with the upcoming holiday. She’d met with her department head and ah, yes, that had been rather unpleasant. Apparently her current supervisor found her efficiency threatening to his role and wanted her to stop being such an overachiever. Hermione had not appreciated that one little bit. And so as soon as she had arrived back, Severus had seen her upset, asked what had happened, and what she needed. She’d asked for him to take her mind off of it, even activated the collar, and... well. Somehow that had resulted in her on her knees between his legs, her arms bound behind her, and a plug up her arse as she sucked him off. He’d never even gotten up from his armchair. Until he’d moved to hold her in place, he hadn’t done a thing aside from summoning the plug and lube, giving her commands, and magically binding her arms. It was, she had to admit,  exactly  what she needed.
