Outraged

"I cannot believe you've forgotten your butt plug!" you yell at the blushing girl, loudly enough to turn several heads. "You know that's not acceptable!"

"I'm very, very sorry sir!" she says contritely, hiding her face while rounding her hips. "I didn't - I couldn't - "

In fairness to her, there is no way she could have. But somehow, that doesn't change how badly you want to punish her for this omission. "Unbelievable" you say quietly, then in a louder voice, "Strip! On your back, knees to your chest!"

"Yes, sir!" she says breathlessly, her beauteous boobs bouncing free as she tears the toga off the upper half of her body. She spins and drops to her back, Her blonde pussy on full display as she assumes the position. She looks up at you with pleading eyes. "I'm sorry - please-" She searches for words as you get into position yourself, finishing breathlessly, "Please give me the spanking I deserve".

She's scrunched her eyes closed and clenched her teeth - you take a moment to appreciate the beauty of her lying, **** and anticipating, in front of you, her most intimate parts proffered for you chastisement.

You start the spanking without any warmup. Her athletic thighs and glutes offer a wide variety of tempting targets, but you focus on only two - her left and right sitspot. You spank Shania hard and fast, alternating between your two targets as quickly as you can without sacrificing power or accuracy. It doesn't take long before you have two clearly defined handprints showing your targets and Shania is whimpering through her clenched teeth, droplets of moisture flying off her engorged lips with every second blow. Without warning you land a softer, but still firm, blow on her instrument of wetness.

"AAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHG! "

Shania screams as the unexpected blow lands, drawing a lot of notice and a few curious onlookers. She opens her eyes long enough to meet yours. "Thank... auhuhuhuhu" she manages as you continue your merciless **** on her two sensitive spots. "oh god, oh..." she loses her capacity for speech as the spanking continues, keeping her body somewhat still and her thighs open through impressive willpower. Every so often you punctuate your staccato rhythm with a clap to her love canyon, drawing shrieks that are equal parts agony and ecstasy from the punished girl. You continue for a good, long time, until her shrieks start to get hoarse and she is crying freely.

She doesn't regain her capacity for speech when you finish the spanking and start rubbing. "Uh... huh..." is all she manages, gesturing at her swollen pussy with a pleading look.

"What did she do?" asks a wondering voice. A handsome older man and a woman who looks young like his daughter - though you'd guess she's probably older than him - have stopped to watch the session.

"She forgot her buttplug" you say as you move between Shania's splayed legs. "And she's very sorry, aren't you?" you add as you lift your own toga

"Uhuh," Shania manages, making eye contact with the blushing woman.

"Come to think of it, show me yours," says the man, eliciting a wave of stuttering from his companion.

His chewing her out and ordering her to fetch a switch makes a pleasant background noise as you and Shania's eyes fill each other's worlds. As soon as you're inside her, her whole body clenches, her arms and legs almost painfully tight as they wrap around you.

The man's ministrations and the woman's shrieks echo across the park as you comfort your chastised mentee. Her soft, soft warmth envelops you as you tease orgasm after orgasm from her body.
