She goes to the gym

“Alright everyone one more minute!” Jenny’s spin instructor said, his voice blaring over the speakers as she sped up on her stationary bike. The teen pushed through the pain in her legs and focused on the music as she peddled as fast as she could.

“Alright we’re done! Cool down time!”

Jenny slowed down, her head resting on the handlebars as she worked on catching her breath. She had just joined the class and had to admit it was an incredible workout as she got off her bike and wiped the sweat off of her arms and face with her towel.

There was one other class she wanted to check out and rushed to the room as it was about to start. As she walked in she noticed the group of pretty young women sitting on the padded floor.

“Come in come in,” the instructor said, a stunning older brunette who looked to be about her mom’s age. She looked remarkably fit Jenny thought as she sat down near the front.

“Good afternoon ladies and welcome to my Advanced Stretching class. In this class you will learn to position yourselves and use your fuckholes in ways you did not think possible in order to better please your users.”

Jenny smiled, eager to train her body to better serve the men in her life.

“Now in order to better train you in this important discipline, James here will assist.” The instructor pointed towards the back of the room.

Jenny’s smile faded as she looked back over her shoulder and nearly burst into tears as she saw who it was, recognizing the man who had fucked her in the Cum Guzzlers bathroom a few weeks back. She looked down at the floor as the man walked through the women to stand at the front of the class, hoping that he wouldn’t notice her. Jenny’s ass had ached for days after he had used her.

“Now James here has probably the largest penis any of you will ever see, so we’re very privileged to have him with us today,” the instructor continues. “James do you want to take a minute to say hello?”

“Pleasure to be here Martha,” James said in the booming voice that Jenny remembered. He looked even larger than the teen remembered as well, towering over the young women as he spoke. “I look forward to working with you girls today.”

“Excellent well let’s get started shall we?” said the instructor. “Now ladies we’ll start simple. I want you on your hands and knees first. Good very good. Now arch your backs a little and stick out your butts. Good. Slide your hands forward so that they reach as far in front of you as you can, with your head resting on the floor. Great that’s great,” the instructor said as she walked about the room, giving some of the girls tips as she did.

“This is an excellent submissive position for being used from behind. James will demonstrate” she said and Jenny stared at the man as he undressed. The women in the class collectively gasped as he revealed his enormous cock. It dangled low between his legs, and Jenny noticed it slowly getting bigger as he approached the front of the class.

He looked around the room before moving behind one of the girls, a very pretty short haired brunette with a golden brown complexion. He reached down and pulled her yoga pants down to her ankles before fisting his now fully erect monster of a cock.

“What’s your name Miss?” the instructor asked as she approached the pair.

“It’s...Pa...Patty...” the girl responded, clearly frightened by the circumstance she found herself in.

“Ok Patty. Not to worry I’ll walk you through this. I want you to take a deep breath and relax. Good. Good. Ok now James? Yes please go ahead and use her.”

Jenny watched as the huge man first grabbed Patty’s hair and fucked her mouth, making sure to get his huge cock nice and wet.

He then crouched down behind the brunette, aiming his cock at her shaved cunt before trying and work it inside her.

“Oofff he’s way too big!” the woman complained, her face cringing as James tried to stuff his cock into her.

“No man is too big and no pussy too small, Miss,” the instructor responded. “Just spread your legs out a little and arch your butt up a little more. Let it happen.”

“Ahhhhhhh dammit!!!!” Patty cried out as James grabbed her hips and slammed his cock into her cunt. He immediately started to fuck the poor girl, hammering into her with long quick strokes. James’ held her ass up and kept pounding into her for a minute until suddenly he pulled out and the brunette collapsed into a whimpering ball on the floor.

“Very good,” the instructor chimed in. “Now Patty here will be better prepared to accept a large cock in the future. It’s very important to remember that positioning will help you to accommodate and pleasure any cock that presents itself to you. James please continue.”

The huge man walked over to another girl, giving her the same treatment he gave Patty, before moving on to another one and then another. After a few minutes it was Jenny’s turn and the teen braced herself.

“I remember you,” James said with a smirk as he got behind her.

“James hold on a minute. I want to move on to another position please,” the instructor said. “Ok ladies please stand up and remove your clothes. Very good. Now for this one James will be lifting you up from behind by your legs and then placing his hands behind your head before inserting his cock into your ass. This “full nelson” position is a very effective way of anally pleasuring your user. James please proceed with?”

“Jenny Miss.”

“Jenny. Very good. James please proceed with the demonstration on Jenny.”

“With pleasure,” the huge man responded.

The teen yelped as she was lifted into the air by the powerful man, who easily pulled her legs up before slamming his cock into her ass. Jenny screamed as she felt her ass being once again busted open the man’s gigantic cock.

James used her like a fuckpuppet, hammering in and out of Jenny’s 18-year old asshole while the rest of the class watched. He moved his hands to her neck, chocking the teen as he kept pounding into her.

“Now class James is demonstrating a **** hold. Very likely something you will come accross. Notice how Jenny’s small frame is able to accommodate the entire length of his large cock in this position.”

Jenny struggled for air, unable to cry out as James fucked her ass tirelessly, pounding her like an enraged madman. She felt him reach down and plunge his fingers into her pussy.

“Ah very good. Pay attention to this class. Notice how James is able to squeeze three of his fingers into Jenny even while her ass is fully occupied by his large member. This showcases how much, with proper training, can be fit inside your holes.”

Just as Jenny was about to black out James let go of her throat. She gasped for air and as she did, felt a massive orgasm take over her body. She cried out uncontrollably as she squirted all over James’ hand. “Oh my God yeah fuck me you motherfucker!” she yelled as she squeezed his cock with her ass.

“Class as you can see, being deprived of oxygen can be a very pleasurable experience.”

Jenny cried out uncontrollably as James fucked her teenaged ass in front of the class.

“James that’s enough. Let’s move on to the next girl?” the instructor chimed in.

“Fuck off bitch,” James responded angrily. “You, crawl over here and suck on my nuts,” he added, looking at Patty.

Patty did as she was told, quickly kneeling underneath the pair and taking James’ huge balls into her mouth. She licked and sucked on them as he continued to lift Jenny’s petite frame up and down on his giant cock.

The blonde teen’s eyes rolled back and her mouth hung open as she moaned and grunted from the anal pounding her young body was being subjected to.

James pulled her off his cock and **** her down to her knees. He grabbed Patty by the hair, placing her face next to Jenny’s before slamming his big cock into the brunette’s throat. Jenny watched as the girl whimpered and gagged while her throat was once again abused by the huge cock. James pulled out and mashed Patty’s face into his balls as he aimed his cock at Jenny and stuffed it into her mouth. The teen’s throat ached as it was stretched wide by the massive cock.

James fucked her face in quick strokes. He pulled out and looked down at Jenny, spitting on her face before grabbing her by the hair and roughly jerking her head back.

“Yeah cum all over my face you fucking asshole!” Jenny cried out as she opened her mouth and squeezed her tits together.

“Fucking stupid whore,” James responded with a grunt as his cock bloated and a thick stream of cum slammed into the blonde’s face. Jenny smiled as she submitted to the one man bukkake that she was receiving as shot after shot of James’ hot jizz filled her mouth and sprayed her beautiful face. Long strands hung from her cheeks and chin before falling to soak her big tits.

After he finished his cock was still rock hard and James turned his attention back to Patty. Jenny spent the rest of the class licking the cum off of her face as she watched him angrily buttfuck the little brunette.
