She thinks you're a monster

Sated, you pull out of her, caressing her as you do. She turns and puts her back against the tile wall, her breathing heavy, her eyes half lidded and wanton.

"You monster," she breathes. "You absolute monster." You reach out and stroke her cheek and she turns and nuzzles your fingers, her eyes still locked on your face, her mouth and tongue soft and warm on your hand. "God you're a bastard. A beautiful bastard, but a bastard nonetheless. No one has ever done that to me before."

"Surprised you in the shower?" you smile.

"Taken my ass," she laughs softly, biting your fingers with her sharp white teeth. "God...I didn't know I wanted it until you started, and then I wanted it more than anything. See what you missed out on that night at the bar? You could have had me instead of my slutty friend."

"You were better," you tell her, stepping forward and kissing her softly. "I don't even remember her. I'll remember you forever."

"Now you are a monster," she chuckles. "Lying to an old lady like that. And your boss too."

"You're not old, you're beautiful. And in here we're Diana and Brian, not employee and boss. You said that yourself."

"Mmmmmm," she purrs. "But what I said before still goes. We have to be careful, and we can't be seen as a couple. But as long as we're discreet, there's no reason we can't continue. But not right now you monster!" she laughs tapping your nose. "I have lots to do before the faculty meeting. Now get out of here and let me finish." She gives you a soft kiss of dismissal that's full of the promise of future delights before pushing you out of the shower and closing the stall door.
