Lean over and pinch her nipples
From Create Your Own Story
You take off your jacket, pretending to hand it to her. Your right hand shoots out and pinches a nipple. She lets out a tiny squeak, loud enough for you to hear, but nobody else hears it. You push your luck, pulling her onto your lap. She gasps, saying, "Brandon, what are you doing?".
"Humiliating you.", you say before jamming a hand into her ruined skirt, brushing your left hand against her wet slit. She gasps again, trying to grab your wrist, but lets go when you softly bite her nipple. She doesn't notice your other hand breaking the last button on her skirt, leaving her bits exposed.
Your push a finger inside, feeling the tight, wet heat of her pussy. She doesn't squeak or gasp, but squeezes your knees.
"Let's see how quiet you can be, my little whore."
"I'm not a whore, Brandon,"she huffs. Interestingly enough though, she doesn't move off your lap. Perhaps you could use this.
"I'll make you a deal. We've got 30 minutes of class left. If you can hold off on cumming until the end, I'll give you my jacket and we'll never speak of this again. If you cum, you're going to be my fuckslut, and we'll run away and you'll do whatever I say, deal?"
Her face screws up in thought, before nodding.
"Sure, you're on."
You smile, before plunging a finger into her pussy and rub your thumb on her clit.
Her eyes widen as you begin fingering her. You lean a little so you can suck one nipple and pinch the other. She stiffens at the new sensations on her body. You kept fucking her with your finger while sucking her nipple, so that allowed you to add not two, but three fingers. You stop pinching her nipple and start pinching her clit.
Does she?:
