Perhaps it was Shinsou’s dislike of big crowds—and the party was anything but a “small gathering,” as Momo had promised—but inevitably you found yourself following your boyfriend through several twists and turns in the grandiose mansion, until eventually he found a deserted hallway. Laughing, you cheekily ask him what he plans to do to you now that you two were all alone, and he smiles, before backing you into the window seat and capturing your lips in a heated kiss.
When you break for air, your head spins, but you’re quick to snap into attention when Shinsou kneels in front of you, spreading your legs to accommodate his form. Your eyes widen, your head darting around to check if anyone’s near.
“Shin!” You hiss. “We can’t be doing this here!”
The smirk he gives you from between your legs is downright predatory, and you’re reminded of the fact that Shinsou—in his well-fitted tux that practically clings to his form, with his tousled hair, staring up at you like you’re the most delectable thing—is the very definition of fuckable. But still. You need to stand your ground.
“I can’t help it. You look amazing in this dress tonight, kitten.” His voice is heavy, laden with lust. Your brain feels fuzzy—whether it’s the wine they served or the way his hands run up and down your thighs, squeezing the flesh the higher he gets—you’re not sure.
“We’re at a party,” you finally say. “What if someone hears us?”
“What if that’s the point?”
“Shinsou!”
He sighs, stroking the tops of your knees with his thumb as if contemplating. When he glances back at you, his gaze is steady. “I want you, (Y/N). I want to taste you,” he says bluntly.
“If you don’t want me, though, I can just—“
“N-no!” Your hand reaches out to grab his shoulder before he can leave. “Please don’t. I...I want you, too.” You bite your lip. “I want you so bad.”
He grins, and once you realize his ruse, you smack his arm. “Shin! Stop tricking me.”
“Who said it was a trick?” Resuming his place between your legs, his fingers graze up your thighs, toying at the edge of your panties. His breath is warm as it ghosts across your collarbone. “Maybe I just wanted to hear... you want me as bad as I want you.” He nips at your neck, and you moan as you feel his fingers stroke you through your damp panties.
“Shin,” you whine. “More—please.”
“You’re gonna have to be more clear, (Y/N). What is it you want?”
“Y-You—fuck—yesss.” You sigh when you feel his fingers finally finally move aside your panties to stroke your clit. His eyes are heavy-lidded, trained on your writhing form. Every gasp and moan you make has his eyes growing darker, until the sensation building on your bud disappears and your panties are yanked down to your knees. “H-Hitoshi!” You scream once his fingers enter you, pumping in and out roughly.
You hear him curse, before burying his face into your neck. “Fuck, (Y/N)... how are you already this wet for me,” he mumbles against your skin, feeling heat rise to his cheeks as well as other areas despite himself.
When his fingers curl inside you just right, your body jerks, thighs clenching around his arm. “Yes—oh god—right there!”
You tremble as he continues curling his fingers, feeling the knot in your abdomen building tighter and tighter. Your babbles become incoherent, lots of yes Shinsou please’s and I love you you feel so good please don’t stop’s and right as you reach the tip of your crescendo, your eyes clenching shut, your gasps blending into mewls—
Shinsou removes his fingers. Your eyes snap open as you whine at the emptiness, at the pleasure that still tingles beneath your skin.
“Shinsou!!”
His voice is strained as he gazes down at your shaking form. “I can’t... I can’t hold myself back anymore.” His fingers make quick work of his tie, yanking it off his neck before gripping your wrists. Jerking your arms behind you, he binds them with his tie, immobilizing you. He bunches your dress around your waist, and before you know it, his head’s between your legs, sucking on your clit.
Your head lolls back, eyes clenching shut once more as you feel waves of pleasure crash over you. Your breath hitches as his name leaves your lips in stutters.
He hums against you, digging his nose into your clit as his tongue delves into your folds. Dizzy from pleasure, your thighs nearly clamp around his head, and his palms grip them to keep them at bay. Your hands want to dig themselves into his hair, yank at the strands, push him away, but pull him in. It’s overwhelming.
Shinsou has always been good at oral, but tonight... tonight he’s attacking you with a fervor. You shiver as his tongue slowly licks a stripe up your clit, making eye contact with him. His hands suddenly grasp your legs and prop them over his shoulders, nearly causing you to fall backwards. But the new angle cause his tongue to hit a certain spot in you that has you seeing stars, and your ankles lock behind his head, your toes curling.
“Hitoshi—p-please—I need—ah!” He hums against you, and the vibrations have you reeling.
When he glances up, his eyes are heavy with desire at the sight of you tied up, flushed, spread out for him. He redoubles his efforts, tongue delving so deep into you that you don’t know where your body stops and he begins.
It becomes all too much all too soon. Your gasps turn into stutters and Shinsou takes notice, pressing his face even more into your folds. When you cum, your whole body thrums in pleasure, legs trembling hard against his head. Shinsou makes sure to lap up your fluids, and you pant as you wait for your trembling aftershocks to die down, your legs slipping off his shoulders to dangle from the seat.
The feel of his tongue gliding against your oversensitive nerves causes you to jerk. “Sorry,” he says, looking entirely too smug when you make eye contact. “Missed a spot.” You don’t miss the sheen of your release on his lips, and your cheeks feel hot.
As soon as he unties your hands, you use them to hide your face behind your palms. “You’re such a...”
He raises a brow. “A...? Don’t tell me you’re speechless, (Y/N).”
“You’re lucky I love you so much, you ass,” you grumble, glaring at him. As Shinsou chuckles, before getting to his feet, your eyes don’t miss the tent straining against the front of his pants, his labored breathing. And when you spread your legs a bit more open, you definitely don’t miss the appreciative grumble he makes. The grin on your face is far too mischievous to bode well for him.
“Hm? What’s this? Don’t tell me you were enjoying this more than me?”
“Guess we’ll have to call a taxi,” you continue. “There’s no way in hell I’m letting you bang me against the window.”
Shinsou rolls his eyes. “Correct me if I’m wrong, but... can you even walk right now?”
“...Touché.”
