A bawling, bare bottomed teaching assistant

A dark-skinned young woman is facing away from you at the foot of Léa's bed, holding on to her ankles as sobs make her naked buttocks quiver enticingly, two circles of well-spanked rawness testament to a very intense beating in progress. A rectangular black paddle with large circular perforations is on the bed.

"Oh, Jaques, I was not expecting you," Léa begins, "Please come in. Ayesha was just training me in the art of the paddle and I think I am finally getting the hang of it."

You exchange a kiss on the cheek, enter and, without being invited, take a seat which gives you a good vantage point of any potential action. Judging from the appearance of the brunette's rump, it's taken quite a bit of practice for the blonde to get her eye in.

"Please, don't let me interrupt, Léa." You wave at her to continue. "I'd be happy to see your technique."

The pretty lectrice picks up the paddle, spinning it in her hand to decide which side to use, then steps to Ayesha's left and with painstaking precision, shuffles her feet into exactly the right positions to give her a stable foundation for a firm swat. Eventually satisfied, she places her left hand on her hip, raises the paddle high and rotates her whole body as she swings it down to thud into her teaching assistant's proffered backside, making her gasp and moan.

"Merci, Mademoiselle, mais un peu plus fort, s'il vous plaît."

"Très bien, si tu le dis."

Léa winds up for another, but this time her body gets ahead of her arm and although the hardened polymer lands even harder, so that it actually bounces off Ayesha's battered cheeks, it lacks control, hitting at a slight downward angle and striking the near buttock more fully than the far one. The recipient's anguished howl proves it wasn't ineffective, though.

"Oups! Mince, Ayesha, désolé."

She's about to try again, when you interrupt.

"May I?"

"Of course, Jaques. Be my guest." She holds out the implement for you to take, but you have something else in mind and step behind her, reaching round to guide her hand. This has the added benefit (for you) of bringing your body into close contact with hers, her lovely bum pressed gently against your crotch.

You steer her into an almost exact slow motion replica of the first swat you witnessed, but at the last moment, you flick Léa's wrist upwards to add a little extra impetus.

"Ah…" Léa nods in understanding. You allow your touch to linger for the briefest moment, the scent of her shampoo wafting to your nose, then you step back in the interests of propriety.

The blonde repeats the motion, an easy swing not needing a great deal of strength, using the weight of the paddle and the application of kinesiology to do the work, expertly applying the flick at the end to devastating effect. This time, Ayesha screams and rolls forward onto her toes, almost falling over. She writhes in agony, briefly unable to speak, fingertips digging into her ankles with the effort of remaining in position. Finally, she gets her body under control and gasps out her concluding assessment through constant weeping.

"Oui, Mademoiselle. Ç'est magnifique!"

"Excellent, Ayesha. On essaiera la tige demain, peut-être."

With a plaintive wail, Ayesha gradually straightens, walking her hands up the fronts of her legs for support, whilst she agrees arrangements for the next lesson. Switching to English for your benefit, Léa invites her to stay for a while, but the younger girl says she has to get going because she has a busy day tomorrow. She wipes her eyes and puts on her glasses and then her skirt, covering a pair of very angry looking weals. When she hobbles to the door, wincing at every step, you would be concerned for her wellbeing, if not for the two facts that you're sure she's had worse spankings in the past and she's not far from campus where you expect she lives.

After seeing her other guest out, Léa turns to you and asks whether there's anything she can do for you.

"Quite the opposite. I'm here to give you your next birthday spanking." You pick up the paddle from the bed where Léa put it after finishing her lesson. "Since we have this to hand, what do you say we try it for the bumps, today?"
