Sit-ups

Finally, you come to the last exercise of the day, and what a hell of one to end on. Your body is sore not only because of the exercises prior, but from the indescribable handjob given to you by your own gym teacher. You were edged for so long, then pushed to climax in front of everyone, and somehow you’re already starting to feel aroused once again. You’re not back on the edge or anything, but you fear it’ll come faster than you’d expect.

“Alright! I’ll be pairing you all into groups of two to help get proper form. I want you to hit at least 100 before swapping!” Coach says.

You wait for Coach Diana to call your name along with another person, partly dreading the idea of being paired with an overly handsy one.

“McCoy and…. Rogers!” Diana says among the list of names you hear. This Rogers person sounds unfamiliar to you, so you hope she isn’t like Rachel, or else you’ll most likely bust all over her, despite having just climaxes minutes ago.

“Fuck!” Samantha says underneath her breath. She looks at you with a mix of spite and embarrassment as she walks over to you, arms around her chest to mitigate her bouncy breasts. You realize that Rogers is her last name.

“Rogers is a… nice name, hehe…” you say, trying your best to make the situation less awkward.

“Get on the ground and let’s get this over with…” She replies, seemingly defeated.

You get down on the ground, not wanting to make her any more pissed at you than you already have. You lie down on your back, cock pointing up at the roof.

“When you’re ready…” Samantha says with little to no enthusiasm to her voice.

You immediately start, using all of your core strength to lift yourself up. As you sit up you see Samantha, who surprisingly seems to keep her eyes on your cock, which is somehow rising to attention once again, so soon after your insane display. While it does seem kind of unfair, you can’t exactly judge her when you’ve taken every opportunity to stare at her body. Even now you can’t seem to pull your eyes away from her perfect boobs.

Eventually, with some struggle, you manage to finish the required thirty sit-ups. You both silently agree to doing the minimum so that this ends quicker, so the two of you quickly swap places.

However, you immediately see the issue with this new position, as there aren't many places for your stiffy to go in your current position. At first you have it lying in the crest between Sam’s firm legs, something she seems to recognize as a necessary evil. But as she does more and more sit-ups, her legs jostle apart, causing your cock to fall between them before she once again closes her legs.

“I-I’m sorry!” You stutter out.

“J-just hold still so we can finish.” Sam says, her face as red as ever.

Unfortunately, finishing is your biggest worry. You suddenly feel thankful for Coach Diana’s handjob. If you didn’t cum five minutes ago, you almost certainly would’ve busted all over Sam right now. Every time she does a sit-up, her legs shift, giving you a strange semi-calf semi-thigh job. To make matters worse, you feel your cock push between her tits each time she reaches the apex of her motion. On the one hand, it’s very painful as Sam squeezes her legs together to keep you still. But at the same time it feels incredible, touching so many different parts of her at once. Your once-again drooling cock head is creating a pool of your fluids on her belly, filling her belly button before all trickling down to wash over her pussy as she sits back up. It’s truly a sight to behold.

You once again feel an orgasm getting ever closer. You know if you cum now there’s a real chance Sam tears your dick off with her legs, but that’s starting to feel more and more worth it with each sit-up she does.

But fate seems to decide you will be keeping your cock today, as Sam comes to her last sit-up just before you reach completion again. She wastes no time getting up and brushing off as much of what you spilled on her as possible. She tries using the same towel from earlier to clean up, but it quickly becomes saturated and just spreads the fluids around over her body.

Coach Diana blows her whistle once again, signaling the end of the exercise.

“Alright, gather up everyone!” She shouts. Once again you and the other students congregate in front of her, though this time you make sure to keep your cock safe from grasping hands.
