You, Mingyu, and Seungcheol can’t keep your hands off each other.
After that night where they had both ended up in your bed, there were no doubts in you or Mingyu’s minds that you didn’t just want Seungcheol to be an occasional guest; that you wanted him to be part of things forever. There was no denying the chemistry between all three of you anyway, let alone the love that you had for both of them. Choosing one or the other was not an option.
A few days later, you and Mingyu had invited Seungcheol over to talk— to lay everything out on the table. He took some time to think about it, which was understandable. Three-person relationships weren’t something you could jump into. The fact of the matter, however, was that he still loved you too, and he liked Mingyu, and so he showed up again two days later, and two became three.
Since then, the three of you have been going at it like rabbits.
The night had started messy, the way it usually does. The three of you made out for what felt like hours, going back and forth: you with Seungcheol, Seungcheol with Mingyu, Mingyu with you, all in a sloppy exchange of tongues and lips and spit, until someone (you) grew needy enough to snap. Clothes were shed, necks were bitten and marked.
You took Mingyu's cock in your mouth while he took Seungcheol's in his, but that didn't last very long. They're givers, of course, always putting your pleasure first before their own, always doing whatever it took to make you happy, however today they were just too hungry.
That's how you ended up here: your nails are buried in the skin of Seungcheol's toned back, your arms draped over his shoulders as his biceps keep you upright against his warm, damp chest and his fat cock drives in and out of you so ruthlessly that you're losing touch with reality. Behind you, Mingyu's hands squeeze at your thighs, your ass, your hips, all while his own thick length fucks in and out of you in rhythm with Seungcheol's.
You're being handled in every which way, bounced up and down like a mere ragdoll as your men use you to their pleasure. Selfish for once, submitting to their deepest primal desires. You let them. Of course you do. You take pride in the way the tight grip of your cunt makes them toe the line of their self-control.
They grunt and groan, their breaths hot against your skin, their voices blending together in a heavy, crude melody. Their balls smack against you with each thrust, and it's so vigorous that it sends fluids splashing and dripping to the floor.
It should be too much. They're challenging enough to take on their own, but they'd managed to stuff both of their girths inside your poor, weeping pussy (with an unbelievable amount of lube, of course), and the stretch was almost enough to make you pass out at first. It took you a while, but with the help of your boyfriends' soft, cooed praises, the sting of being borderline ripped apart had blurred into a deep fullness unlike anything you had ever felt before.
Now you're on the verge of both climax and insanity while your boyfriends stand up with you in their arms, treating you like a mere fleshlight.
"Doing so good for us, aren't you, princess?" comes Seungcheol's voice, hoarse and a little out of breath, his teeth slightly gritted. He knows how it affects you when he talks to you— when Mingyu does, too— keeping you grounded when he prompts you to reply, yet simultaneously coaxing you closer to your orgasm. "How does it feel?"
"S-so fucking full," you manage in a whimper. It's a wonder how you can still speak, your head empty with nothing but the thought of cock.
"But it feels good, right, baby?" Mingyu rasps behind you, mouthing at your neck with those fangs you love so much, his hands squeezing at your thighs.
"Yes!" you cry, your head falling back against Mingyu's shoulder. "I love it."
"Good girl," Seungcheol groans, bouncing you up and down with a little more vigour now. "Gyu, you close?"
"Been close the whole time, hyung," Mingyu replies, his voice strained with what you now recognise as discipline. "My boyfriend's cock rubbing against mine inside our tight little girlfriend… I almost busted immediately."
Seungcheol barks out a breathless laugh while you whine, your cunt clenching around them both at the picture Mingyu paints.
"Please do it… Want all of it," you pant, reaching your hand backwards to grab Mingyu's neck, pulling his mouth to yours in a hard, sloppy kiss. It's hard to not get lost in the taste of him, your tongues tangling in a wet, hot dance while Seungcheol groans at the sight.
"You want our cum, baby?" he rasps, his hand reaching for your face, pulling you away from Mingyu with a firm hand forcing you to stare at him. There's still a lingering jealousy in his actions sometimes. You expected it— Choi Seungcheol is possessive to his core. Though it's not like you and Mingyu are all that innocent either.
"So fucking bad," you cry, your words slurring together now.
"Cum for us first, pretty girl, then we'll give you what you want, yeah?" Seungcheol says. How chivalrous.
You give a weak whimper, neither in protest or agreement, while Mingyu moans out: "hyung… I don't know if I can hold out."
"Yeah, you can," Seungcheol coos with soft encouragement in his voice, but there's a glimmer of something a little darker in it— a flash of the authoritativeness that lives deep inside in him— and that's all it takes to quell Mingyu's argument.
The younger man bites down on his bottom lip hard, channelling every drop of discipline he's ever learned into staving off his orgasm. He tries not to think about how fucking tight it is, shifts all of his focus to grinding his cock against that sweet spot that'll have you falling apart as soon as possible.
It only takes another few moments, of course, as the deep fullness of having your pussy stuffed with two cocks becomes too much to handle and your orgasm comes hurtling towards you. You cry out, loud and depraved, curses spilling from your lips as your body becomes utterly taut with white hot pleasure.
Seungcheol and Mingyu hold you in their arms as you fall apart, their hips hardly letting up their relentless, animalistic thrusts, your walls clamping down around them so harshly that it's impossible for them not to cum right after.
And Mingyu is always a little louder when he cums, more whiny and depraved. Seungcheol whines too, only he's a little more reserved, but not out of timidness. Rather, he is usually too breathless. He runs out of stamina quicker. Doesn't have the energy to moan by the time he's finishing, too spent and exhausted from the weight of giving.
They fill you up until you're thoroughly, positively stuffed. Until it oozes out and ruins the sheets below, but even then, your men only watch, grinning like insatiably hungry dogs.
Your period is late. It shouldn't be late. It's never late.
It's just stress, you tell yourself. You're not eating right. Maybe you got your menopause early.
It wouldn't hurt to check though, you think. Just in case, right?
Mingyu and Seungcheol are at the gym together, so you tuck yourself away in the bathroom, and you wait. You're too anxious to look away from the stick as you wait, recalling every time you had taken your pill, assuring yourself that you're far too meticulous and careful to slip up.
Your boyfriends come home right as you let yourself relax with a sigh because you're right— there's only one line.
What you don't expect is for them to burst into the bathroom, glossy with sweat, looking pumped up in their matching tight shirts, and wearing matching little devious grins.
"Hi, baby," says Seungcheol. "We were hoping you'd shower with us."
Mingyu spots it on the counter first, but he's always been a little more attentive.
"What's that?" he asks, as if he doesn't know.
You scramble to hold it up to them. "It's false!" you insist, stifling a laugh as they blink almost simultaneously. "My period was late, so I did it just in case."
Mingyu's brows furrow as he takes the stick from your hand and holds it up close to his eyes. You want to remind him that you've… peed on it, but then he speaks. "There are two lines."
"Gyu, you're seeing things," you say, rolling your eyes as you grab it back out of his hand and look at it again, a little closer this time, and your heart drops to the floor.
thank you for reading! feedback, comments, and reblogs are much appreciated :)
ushijima updates are always so <3333 doesn’t know what dragon ball is, naps a lot, likes that kids call him volleyball terminator, wants to be more amiable so he can promote the sport, birds land on his shoulder. what a guy.
men who want you to be bitchy—who poke and prod until you snap because they love it when you’re nasty and reckless and mean. they smile sharply while you snarl and hurl insults at them until you’re tired, huffing fire that fizzles out all too soon once you realize that you played right into his desires.
