Let's get her all red and ready and dive right in

"You're looking a little sore down here," you say as you run your hands over Sarah's red ass.

"Yes, Sir," she says. "I'm sorry that I came without your permission."

She flinches as you squeeze her tender cheeks. "Does that hurt?"

"Mmm, yeah," she says. You squeeze a little harder, and she winces. "Ouch!"

"And did you learn your lesson?"

You squeeze again, and she gasps, "Yes! Yes, I learned my lesson!"

You smack her ass, hard, and as she yelps you say, "Yes, what?"

"Yes, Sir! Yes, SIR!"

"That's right," you say, rubbing her luscious flesh softly again. "And don't forget it."

"I won't."

SMACK!

"OOOOOOOW! I'm sorry! I won't forget it, SIR!"

"I have a question for you, pet."

"Yes, Sir?"

"Are you ticklish?"

"What?" You raise your hand, but before you can spank her again, she quickly adds, "Sir."

"I asked if you're ticklish."

"Um, I don't know, Sir. Maybe?"

"Let's find out," you say as you run your hands along her soft ribs. She starts to giggle and thrash, but with her arms bound beneath the table, she can't get away from you. She's laughing and screaming and you continue to tickle her sides and underarms, relishing the side-boob you grope along the way.

"Stop! Please, stop!"

You stop and give her a moment to breathe. And then you smack her ass twice more.

"Ow! Fuck! Ow!"

"You really haven't learned your lesson."

"I'm sorry, Sir, I---HAAAHAHAHA!" You've started tickling her again, and again she thrashes and squirms under your touch. You remove your hands from her and while she breathes heavily, you spank her still-reddening ass again.

"OW! Hey! What was that for?"

SMACK.

"FUUUUUCK! I'm sorry! I'm sorry! Sir! What was that for, SIR?"

"Because I like spanking you, pet." SMACK!

"OOOOOOOWWWWWowowow." The nurse thrashes around the table, straining against her restraint. While she does, you tickle her again, roughly, squeezing her sides pinching her thighs and brushing the soles of her feet.

"Pleeease, Sir! Please stop! Please!"

You continue a bit more and then give her one more spank on each cheek. You step away, giving the nurse a chance to catch her breath. Her eyes are closed, and her chest is heaving. Quietly, you sneak closer and place your hand on her pussy. She gasps, involuntarily jerking away from you, and you spank her again.

"Don't pull away from me, pet."

"I'm sorry, Sir," she gasps. "You surprised me, that's all."

You gently rub her lips, noticing they are already lubricated. Her legs pull apart, and you slide a finger into her wet pussy.

"Does this feel better, pet?" you ask quietly.

"Mmmm, yes, Sir. Please, more of that."

You finger fuck her slowly with one hand and run your fingers through her dark hair with the other.

"I'm going to fuck you now, my pet."

"Yes, Sir," she breathes. "Yes, Sir... Yes, Sir....."

You pull off your pants and slide on a condom (the way she showed you!) as you indicate to Rebecca that she should begin recording. You grab Sarah's waist with two hands and tug her ass up. This causes her arms to stretch even farther forward and her face to smash into the table, and though you're sure she isn't comfortable, her pussy is now elevated where you can reach it with your cock.

You climb onto the exam table behind the nurse and slide into her. She moans loudly and thrusts her hips backward, pressing her ass against your abs as you slide deep inside her. You've had sex before, of course, but never in a situation so wild as this.

Grabbing her delicious love handles, you begin to thrust in and out. You time your thrusts against her heavy breathing. She's moaning and twisting and **** for more, but she can't really move very much. You are totally in control.

As you press into her with more ****, her moans become whimpers. Her pussy is clamping down on your throbbing cock, but since you're wearing a condom and she just made you ejaculate earlier today, you're not sure that you're going to cum.

Still, you're having a lot of fun.

"Please, Sir, may I cum?" she squeaks.

"Not yet," you say as you continue to plow into her. You shake the table with more and more **** as you quicken your pace.

"Oooooooh Gooooood," she moans. "Pleease, Sir! Pleeeeease, may I cum, pleeeeease?"

"Not yet," you say again, thoroughly enjoying her discomfort.

She goes quiet, spending all her energy on trying not to orgasm. Finally, she squeaks out a meek, "Please, Sir? Now? May I cum now, please?"

Her meekness is thrilling, and you finally relent. "Yes!" you shout, and she releases a long, high pitched whine as she convulses around your penis. You continue to fuck her forcefully while she cums and then, shortly afterward, cums again.

You can tell that she's exhausted and extremely sore, so you gently slide out of her, still rock hard.

"Mmmmm," she moans. "Thank you, Sir."

Rebecca flashes you a huge smile and give you a thumbs up as the stops recording. You slide the condom off your erect penis as Rebecca places the phone in her pocket and walks closer to you. It looks like she wants to say something, but the panting nurse doesn't even know she's here. Is she going to give herself away?
