The First Lesson
Her Mistress laughed, pulled her shoe away from Jen's lips and walked around the kneeling girl.
"Get up" she instructed, Jen obeyed.
"Bend over my desk"
Jen's heart began to quicken, she moved forward and lowered herself across the broad stained-wood desk. Her breasts bulged outwards as they were pressed onto the writing pad. She hooked her hands over the far edge of the desk, holding on to it as though she thought she might slide off.
The desk was not quite waist high and therefore her back was arched up towards her bottom, which sat proudly, highest of all. The tiny plaid skirt was no defence for this sort of position; it simply lifted up, providing a frame for the soft, perfectly formed pillows of her backside. The suspender straps now pulled tightly across her, causing two shallow grooves across the otherwise perfect roundness.
Jen was acutely aware of the cool air caressing her arsehole. Without her knickers, and placed in this position it was a part of her body that was sensitive to being so exposed. She imagined its puckered shape, larger than life, standing proud now for all to see. The blood rushed once again to redden her face.
But her arsehole wasn't the only thing reminding her it was being exposed. Her pussy was already wet, and that wetness reached out to the fresh air, sucking the coldness in, providing sensations in direct contrast to the heat going on inside.
She sensed her new Mistress approach from behind and then gasped as a hand stroked her exposed flesh. The other woman's hand was cold where it had been holding the wine glass. Jen could detect every move it made across her upturned rear.
"Move your legs apart," Mistress instructed slapping at Jens thighs, Jen silently obeyed.
The Mistress started sliding her hand up over Jen's thigh and backside. She made a claw with her fingers so that she could scrape over the presented flesh with her nails. The sensation sent shivers speeding through Jen's system. In her mind's eye Jen pictured a cat pawing its captured mouse.
Once more Jen gasped as she felt the nails, sliding up the stockings of one leg. Up and up, across the lace tops and onto flesh. Jen couldn't believe how turned on she was, 'please touch it, please touch it!' But the nails stopped, and started again on the other leg. Scraping up the inside of her thigh. This time as they approached the very top Jen could not resist and subtly moved her crotch down to meet the rising hand. Her pussy briefly had contact, but it was immediately withdrawn, and then just as immediately a stinging slap struck her on the arse. The moan that had been forming in her throat from the contact with her pussy, exploded out as a gasp at the stinging blow.
"Fucking bitch" reproached the Mistress, "How dare you put your enjoyment above my own!"
"I'm sorry Mistress," pleaded Jen with genuine regret. It scared her when someone took issue with her, especially if they were harsh to her. "I couldn't help it."
"Well you'd better bloody learn to help it." Her Mistress grabbed something from the desk.
Jen was about to issue another plea for forgiveness when another stinging blow landed on her backside. She rocked forward on the desk. Her Mistress had used a ruler to strike her. She had felt the flesh on her backside wobble with the force.
Just as the stinging was fading to be replaced with a far more pleasant warmth, another blow landed.
"Ahhh..."
"An early lesson for you my slut," said her Mistress, followed by another strike across her bottom.
Her Mistress then reached out her hand, Jen flinched at the sensation expecting another blow but her Mistress was stroking the reddening flesh in front of her.
"Ahh feel that warmth," she commented "Lovely."
She then reached down between Jen's legs and tickled her pussy lips,
"Is that what you wanted?" She asked teasingly
"Ohhh," moaned Jen, she couldn't keep up with the rapidly changing sensations taking over her body
"My! You're a juicy one," added her Mistress as she rubbed Jen's pussy some more.
Jen couldn't stop herself moaning, she hadn't believed it was possible to be so turned on, she was completely helpless to the yearning inside her. With each manipulation from her Mistress she moved nearer and nearer to orgasm. Then without warning – SMACK – another striking blow across her bottom. This one had been low; the draft caused by the speeding ruler blew between her legs teasing her sopping pussy with cold fingers. The mixture of sensations was delightfully agonising.
"Your pleasure is mine to give," SMACK, "oohh"
"Or mine to take," SMACK, "aahh"
"If you want something, anything, you will ask me," SMACK, "mmnn!"
"If it amuses me you will beg me," SMACK
"Has this lesson been understood by you?" SMACK, "oh! Yes Mistress, I'm sorry Mistress"
"Have you learnt from this?" SMACK "Yes Mistress, thank you Mistress."
