"You.Always you."Her voice breaks slightly."I was thinking about your mouth on me.About how you made me come so hard I couldn't think straight."
I press the vibrator against her lower back, still not turning it on."Such filthy thoughts in my classroom.What else?"
"I kept imagining you bending me over that podium.Taking me right there while everyone watched."She's practically panting now.
"Exhibitionist fantasies now?"I lean closer, my chest against her back."My brilliant student has such a filthy mind."
"I was so wet I could barely concentrate," she pants.
"Were you?"I slide the vibrator around to her hip, then down toward her thigh."Show me."
I reach around with my free hand, sliding my fingers between her legs from behind.She's soaked, hot and slick against my touch.A groan escapes my throat at the evidence of her arousal.
"Fuck, Skye.You're dripping."I place a soft kiss on her lips."Just for me," I murmur, circling her entrance but not pushing inside."Is this what you wanted during class?My fingers inside you while you tried to take notes?"
She nods, a whimper escaping her lips as I withdraw my hand."Please..."
"Please, what?"I turn on the vibrator, the low hum filling the room."Use your words, Skye.That brilliant mind of yours should be able to articulate what you want."
"Please touch me," she gasps, trying to press back against me."I need you inside me."
I bring the vibrator to her inner thigh and trace it up to her clit before sliding it inside of her.She gasps sharply as the vibrator slides inside her, her body arching against the intrusion.I hold it there, watching her face as pleasure washes over her features.
"Is this what you were thinking about during my lecture?"I twist the vibrator slowly, pushing it deeper."Imagining me filling you up while you sat there pretending to take notes?"
"Yes," she moans, her hips moving instinctively."No."
"No?"I ask, adding a slow thrust of the vibrator.
"I wanted you inside me, not this," she moans.
When I pull the vibrator away, she whimpers at the loss.Standing, I unbutton my shirt, watching her eyes track every movement.When I shrug it off, her gaze roams hungrily over my chest.
"Much better," I say, working on my belt."But you're still going to have to earn it."
The leather slides free with a soft whisper, and I see her eyes dilate at the sound.I know what she's thinking.We've played with restraints before, but never like this.Never with the classroom dynamic bleeding into our scene.
"Stand up," I command, and she rises on unsteady legs.
I guide her to my desk, pressing her forward until her hips hit the edge."Bend over."
She complies immediately.Her bound hands force her to rest her weight on her chest.
The position leaves her vulnerable, exposed, her ass raised in perfect submission.I run my hand over the curve of her backside, feeling her tremble beneath my touch.
"Perfect," I murmur, stepping back to admire the view."Just like I've imagined all day."
I finish undressing, my clothes joining hers on the floor.The cool air of the room hits my skin, but I'm burning up inside.
"What's your safe word, Skye?"I ask, running my hands down her sides.
"Red," she breathes, turning her head to look at me over her shoulder.
"And if you need me to slow down but not stop?"
"Yellow."
"Good girl."I position myself behind her, letting her feel my hardness against her without pushing in."Remember those.Because I'm not going to be gentle with you tonight."
