You and (U/n) are rivals. You both have the looks, both have a steady fanbase at school, and both have a blazing yet unique charm. Sure (U/n) might be a bit smarter, but you win back by your slightly firmer figure, so the both of you are still even.

But, despite having such a rivalry going on between the two of you, your rivalry is also what brought the two of you together as a couple. Your daily schedule consisted of bickering (like an old married couple) during the day, and heavily make out with your rival during the night.

Of course, there would be times where either one of you would come up with ideas to beat each other. "Let's see who can eat the most cookies, let's see which of us can attract more people into participating in school activities," which, all ended in ties.

But today, there wa's a rather unusual topic.

"Hey (Y/n), let's see which one of us can resist an orgasm during school."

"During school?"

"Why do you ask? Don't think you can take this on? Are you going to be a premature ejaculator?"

"Of course not! I'll take you on, and I'll beat you so hard, you won't be able to stand for days!"

"Why the fuck are you staring at my ass?!"

"It's my prize, so I'll win for sure."

"I won't let you, don't think I won't go down without a fight."

"That aside, how do you even plan on doing it? Sex during lunch?"

"No, it'll go on all day. We'll get some sex toys with remote controls, maybe a vibrator around your dick, and I'll have a vibrator in my ass. We'll find ones that can only go off for a set period of time, with a cool down or something. We'll get each other's controllers, and see who can last longer."

"Hah, alright (U/n). Get really to get a good pounding once I win. I'll really make sure you're unable to walk the next morning."

"Well then, I guess you'll have to accept a wish of mine if I win, right?" He smirked in response. "You seem like you can't live without giving that dick of yours some attention, if I win, you better get ready to retire your thing for a month or so."

"We'll see about that."

And so, the day finally came. Both of you entered school grounds with sex toys equipped, and were definitely ready to beat the other.

As per usual, the day started with a bunch of bickering, mostly about trivial things, with the occasional muffled buzzing catching a few of the student's attention.

The loud ringing of the class bell came around, and everyone had moved to their seats, while the professor had begun to preach sleep-inducing info to the class.

Of course, two of the students were busy with other tasks, such as clicking a button every now and then, causing small short flinches from the both of them.

Lunch soon came around, where the two had fled to their usual spot, one of the only spots where they could be alone with each other during school. And by now, they were both blushing made, with tingling feelings coming from their lower groin region.

"You know.." you start, stirring restlessly at your lunch. "I'm sure there's something the both of us desperately want to do right now," you said, eyeing your partner with a smirk.

"You read my mind," (U/n) hummed, placing his untouched lunch down and straddling his legs around your waist, rolling his crotch against your semi hard on.

"It involves a lot of fucking, doesn't it?"

"Sure does baby," you replied, palming the soft tent forming in his pants. Taking this opportunity, you turn on the vibrator as well, making your boyfriend let out a chain of soft mewls and moans. It didn't take long before you felt vibrations on your dick, and overserved the smirk on (U/n)'s face as he became the ultimate tease, rolling his hips over your crotch.

As if he was doing a strip show, (U/n) slowly took off his pants, grabbing two condoms from one of his pockets and using one to stretch himself a bit more, since the vibrator had already done most of the stretching, and put the other on you, of course, rubbing up and down your shaft in the process.

"C'mon now, give it to me," your boyfriend hummed, turning his back towards you and giving you a sexy grin as his hands spread his butt cheeks, revealing his slick entrance.

You didn't need to be told twice, hitting the remote once more before sliding your thick meat right on in.

An orchestra of moans and groans came out as the two of you became one, the vibrations inside of (U/n)'s ass hitting your tip repeatedly, teasing you alongside the vibrations of the loosely attached ring. The deserted area was soon flooded full of your erotic panting, both of you thoroughly enjoying yourselves, and not forgetting about the vibrators too. Slapping sounds echoed loud and clear as your movements got rougher by the minute, (U/n)'s slender body quivering with every thrust you make. Your hips were thrusting at an incredible pace, with sweat now soaking through the shirts of both you and your lover.

"Gonna cum..~" both you and him groan, before both of you squirting out your semen. Panting, you could feel (U/n)'s insides throbbing from the harsh activities you both just went through, and coincidently enough, the vibrators had run out of power.

"So," (U/n) panted after regaining his breath, "who won?"

The two looked at each other, both contemplating the answer.

"We should go again," you replied with a determined look on your face, which was practically glowing from having good sex.

"Sounds like a deal to me, I'll make sure to make your dick burst before mine."

"We'll see about that~"
