Jumping Jacks with an incredible climax

You and your female classmates are standing side by side, facing each other in a set of four lines. And as if it isn’t obvious enough, Diana has you facing Samantha.

She keeps her hands around her chest, forgoing her coverage of her crotch. You struggle to keep your eyes off of her thunder thighs and pussy, but when you do, you just end up staring at her tits.

“Keep staring at me, and you won’t live past Friday.” She whispers at you. Her anger is tinged with a bit of truth, as you have no doubt she could easily kill you.

“Alright! Time for jumping jacks! Let’s aim for high numbers, ladies!” Coach Diana says. And with the same countdown, you and the other women begin.

It starts off pretty normal. Without the need to glide your cock against the floor, this is the most normal exercise you’ve done yet.

Normal with the exception of Sam’s beautiful body bouncing in front of you. Even though she told you off, multiple times, for staring at her body, you can’t help but stare at her. Her chest bounces up and down vigorously with each jump. The way her chest bounces reminds you of a pair of pendulums, except more chaotic and made of smooth skin. You can even make out a quite slapping noise, the noise of flesh slapping against each other.

Whether it’s coming from her tits colliding or her ass cheeks clapping together doesn’t matter, it’s still hot as hell to you.

Her body turns you on so much, that you start dripping more pre-cum out of your cock. But due to your cock violently flailing around, you spew your liquids onto Samantha.

Your pre-cum splatters all over her body. Her thighs, her tummy, and her beautiful bosom. You even spew a bit on her face and into her mouth.

“You think this is funny, huh?” Samantha says, face completely red with embarrassment and rage. She is coated in your pre ejaculate at this point, her hair matted down and her body glistening in the light.

“I-I’m sorry, I can’t control myself.” You say, wincing as you prepare for the beating of your life. But before Sam can do anything, she is interrupted.

“Who turned on the sprinklers?” Coach Diana says, trying to hold in her laughter.

You try to ignore what she says, figuring it to be one of her little one-off quips, but Coach Diana comes closer to you, and blows her whistle.

“Alright alright Mr. McCoy, enough’s enough,” she says chuckling.

You stop your jumping jacks, as do the rest of the women around you.

Coach Diana looks around, her eyebrow raised. “Woah woah woah, ladies! I told Mr. McCoy to stop! Everyone else, keep jumpin’!”

The others look around at each other, and get back to their jumping jacks, although they’re all still watching you and Coach Diana intently. She looks at you with a smirk, saying “now this is fuckin’ hilarious, but you’re making TOO much of a mess. Dripping all over the floor is one thing, but spraying all over these hard workin’ ladies? That might cause some issues, as great of a show as it may be.”

She puts her hands on her hips as she laughs. Then, without missing a beat, she swings behind you. You can’t believe what you feel next.

Coach Diana’s hand around your cock. Before you can process what’s going on, she starts pumping away.

You were already on edge, your cock throbbing and pushing out precum. But with this beautiful, strong, dominating woman jerking you off from behind in front of an audience of just as beautiful women (including a gorgeous naked one), you’ll only last a matter of seconds. Despite this, you resist, and try your hardest to push back the inevitable.

The women around you have stopped jumping, their eyes locked onto you with complete focus, most of their jaws agape, their eyes shifting to one another, almost as if to make sure this is really happening.

“Hey!” Diana yells, “I told you ladies to keep jumping!”

“Fuck that!” Sam exclaims while gesturing wildly, “you’re just gonna start jerking him off in front of us like it’s fuckin’ nothing?!”

Diana, briefly slowing her hand down, does not hesitate to retort, “Cool it, fireball! I think we can all agree it’s in our best interest if Heath finds some relief now, and that I help nip the whole human sprinkler thing in the bud! Unless you’re into him glazing you, in which case, I wouldn’t blame you!”

Sam blushes (even more than she already is), and takes a few steps back.

You hear all these words, but can barely process them, as Diana brings her hand back up to speed. Her grip is so strong, much stronger than yours has ever been, although maybe not as tight as Sam’s iron grip of rage…but this feels better…It feels incredible…It’s intoxicating.

Forcing your eyes open, you see all the women jumping, sweating, panting…their eyes still focused on you. It’s an ocean of lustful gazes and eager smiles. You can see Claire, with a sadistic grin stretched across her deceptively cute face. You can see Rachel, who looks absolutely enamored, like she’s genuinely in love with your body and the way it’s being used.

And then…there’s Sam. Normally she’d scold you for staring, but right now she’s averting her eyes from the shameful display Coach Diana is putting on with you, so she doesn’t notice your **** gazes. How could you look away? She’s fully naked, drenched in sweat, her skin sparking with your precum, and all of her assets bouncing up and down over and over again as she does her jumping jacks. Of course, you’re most focused on her huge tits, swinging like pendulums.

Watching the young woman move up and down, your mind wanders. You haven’t been one to actively picture having sex with specific women, but right now you, seeing Sam move like that, and feeling the hand moving up and down on your dick, you can’t help but imagine her bouncing like this on your cock instead.

That’s enough to send you over the edge, but right before you do, Diana leans in by your ear, and in a sultry voice, whispers “Why so quiet? Make some noise, champ.”

You’ve been making the futile effort of minimizing the severity of your display, but you’re so lost in euphoria that you can’t ignore this command.

With no shame whatsoever, you belt out “HOLY FUCK! I’M GONNA CUM!”

And cum you do, like never before, and that’s saying something with your other incidents today. You nearly drown in the wave of euphoria that crashes over your body.

Somehow, there’s still a lot of cum left in you, as you fire off shot after shot after shot. Your gym teacher’s grip gets tighter with each burst, causing you to moan each time. Your cum forms a huge puddle on the floor right in front of you.

Your senses are deafened by the chorus of nearly fourty girls all cheering. You struggle to open your eyes, but you can just see just a bit. You see Claire pointing at you while laughing her ass off to the point of tears, saying something to all of her friends, not that you can hear over the uproarious applause. You see Rachel with the same kind of goofy smile as a little girl in love, as if she has butterflies in her stomach. She nearly collapses, and is caught by one of her friends, laughing. You see Sam, who’s red from head to toe, struggling to avert her gaze, but is positively shaking with some form of excitement. Her jumping jacks over, she’s able to cover her body again, but has elected to put both of her hands over her pussy, leaving her beautiful breasts exposed.

You’re weak in the knees, and as Coach Diana lets go and backs away from you, you fall right on your ass.

It seems you weren’t quite done, as your cock spurts out one last little load of cum onto your stomach.

Just like that, your post-nut clarity starts to hit, as you realize how insane this latest display was. You just got jerked off by your teacher, in front of your class of dozens of women, ultimately busting due to the embarrassed naked chick jumping up and down ten feet away from you.

What the fuck is happening anymore? This was insanely arousing much like your last two ejaculations, unlike anything you’ve ever felt before today, but it was also astronomically embarrassing. These women have seen everything! What more shame do you have!? What else is there to even hide!? And it’s only your first day!

Diana comes back and crouches down above you, smearing her cum covered hand over your bare chest, before licking the rest off her fingers.

She throws a Wet Floor Sign down over the puddle of semen you left on the floor. “Let’s leave that for the janitor to clean up later!” she says with a laugh.

The coach blows her whistle. “Alright ladies and Heath! Look alive! Next up is your final station: sit-ups! You have 30 seconds to be in position!”

The others move around to their space, giggling and talking amongst themselves.

You’re hardly conscious, but you start to wake up, just in time to see Sam approaching you. She leans over you, her big tits dangling in your face. You use all your willpower to look her in the eyes.

“Listen here, perv! Everyone else may have loved that shit, but I still think you’re fucking disgusting!”

She marches off before you can say anything. Somehow, despite just cumming barely a minute ago, you already feel a rising heat in your gut, and can’t help but watch her grab a towel from the bleachers. You take note that the first thing she does is move to wipe down her pussy and inner thigh. Was she…wet? As she dries herself off, she notices you staring.

You manage to peel yourself off the ground and head to your next station, while Samantha looks down at the floor, her whole body still blushing.
