Physical punishment!

The Gym instructor lead Sabrina down the hallway to his office. Beside the door a nameplate read 'Mr Ready, Physical Education'. Once inside he closed the door and took a seat at a small desk set against the wall. As she looked around she saw that the rest of the room was filled with various sporting equipment.

"Now, explain what you were doing in there?" said Mr Ready.
"Oh I got lost. the signs were missing and ... " She started, but he cut her off.
"So you were lost in there for an hour, were you?"
"I umm, the boys just wanted some fun!" Sabrina smiled.
"Fun eh?" Mr Ready scowled, "Ill show you fun!"

Suddenly he grabbed her by the wrists and yanked her forwards so she fell over his lap. With one hand under her he undid her jeans and before she knew it he had jerked down her jean and panties, exposing her pert ass.

"Now we'll have some fun!" he grinned evilly and holding her down with one hand he began to spank her.
"Ow, ooh, ahh!" she yelped, "No, ow, please, ooh, stop!". But he ignored her pleas and continued to slap her ass hard. 'Right, you asked for it!' thought Sabrina and wiggled her fingers. But nothing happened. She tried again. Still nothing
"Hahaha!" laughed Ready "Trying something? Didnt you realise, Im a Warcock and your powers wont work on me!". Then he gave Sabrinas ass a final hard slap and wrapped her in his arms. Lifting her up he carried her over to a gym horse and despite her struggles tied her wrists to the two handles. He took his time pulling off her jeans and panties and lifting her tshirt so her young ripe breasts were exposed. Finally he took off his own clothing to reveal a taut muscular frame and a massive thickly veined cock. Looking over her shoulder she gasped, it mustve been about 12 inches long and it wasnt even erect yet. That soon changed as he stepped up behind her and stroked one hand along its length.

"Now you will know pleasure!" he growled and she saw nodules arise from the skin of his shaft and ripple up and down it rythmicly. Then he grasped her hips and pushed the first quarter into her pussy, still damp from her locker room fun. Sabrina gasped as she felt the nodules massaging the inner walls of her vagina.
"Please... Ill be good!" she wimpered but he ignored her once more and fed the next quarter of his cock into her. Sabrinas pussy was already stretched to its previous limit, 'Ill never take that whole thing!' she thought. But the nodules continued their work and she realised she was wetter than she ever thought possible. Wet enough even to take the next thrust which came a few seconds later.

"Ahh ahhhh, Oh..my god!" gasped Sabrina, "Youre ahh in my..."
"Womb! Yes. Delicious isnt it?!". She couldnt help but gasp as she felt her cervix stretching along with her vagina to accomodate his huge penis. And still there was more to go! She didnt have to wait long for the final thrust, and with Readys cock embedded as deep as it was physically possible she felt like a piece of meat on a spit.

Finally the fucking began in ernest, and sabrina found herself totally unprepared for the sheer pleasure that poured from her loins. As he pistoned his cock in and out the motion accentuated the nodules abilities and within a matter of minutes she was shuddering to her first incredible orgasm.
"Scream all you like bitch, these walls are sealed against sound!" he goaded. As her second orgasm approached she couldnt help but take him up on that.
"Oh god, help meeeeeee!" Sabrina screamed. Her juices flowed thicker and more freely than ever and they trickled in almost a steady stream to puddle on the tiled floor.

For the next 15 minutes Ready fucked Sabrina, his massive cock plumbing the depths of her vagina and driving her half out of her mind with almost unbearable pleasure. She was past caring when he groaned and delivered his spunk directly into her womb, and then released his grip on her hips so she dropped to hang from her bindings. She was started awake by the splash of cold water over her still naked body.
"Wake up my little ho!" he said, "Time for you to get to class!" She realised he'd dressed her again and stumbled out of his office in a daze.

Sabrina managed to stagger back to her dorm before she passed out on her bed...She was awoken by a wet sensation on her face.
"EEwww, SALEM!" she cried as she wiped the cat spit off her cheek.
"Sabrina. You were out like a light! Bad class?"
"You could say that." she replied, and went on to describe her encounter with Mr Ready, the Warcock.
"Oh no!" said Salem when she had finished.
"Whats up?" she asked.
"Well, if Mr Ready is a Warcock and he came inside you youre in trouble Sabrina!"
"Trouble?" she replied warily.
"Yes. Warcock sperm is super addictive and super potent!"
"What does that mean? Super addictive?"
"Just that in a few hours youll feel you need to be fucked by him again, and that feeling will only grow as time goes by until it become irresistable."
"Thats bad. And the super potent bit? Its worse isnt it?"
Salem nodded. "Literally seconds after he came in you his sperm will have found your eggs. Youre PREGNANT, and theres no way, not even magicly, you can get rid of a Warcocks baby!"
