Chapter 1?
The morning sun spills golden light across the quiet street as you stand at the door, watching your husband pull out of the driveway. You kissed him on the cheek as a goodbye, the same way you always do—light, practiced, distant. He barely looked at you, barely muttered a word before driving off to whatever keeps him too busy to notice you anymore. You sigh softly, rinsing your hands off in the sink to wash away the sticky remnants of sugar and lemon juice, drying them on your apron. But then something catches your eye through the window.
A jogger, gliding down the street with effortless ease.
White hair. Eyes as blue as the summer sky. And—oh. Oh.
He’s shirtless.
The breath leaves your lungs in a slow, silent exhale as your gaze follows the lean, defined lines of his torso, the way his muscles flex with each stride. He’s young—too young, probably—but that doesn’t stop the warmth from curling low in your stomach, something you haven’t felt in… goodness, how long?
He moves with an easy, effortless grace, muscles shifting beneath sun-kissed skin, his face half-hidden beneath a mess of white hair. You don’t mean to stare, but—well, you are only human.
“What is he doing?” You mutter under your breath, shaking your head. Fool. Doesn’t he know it’s hot outside? The kind of heat that makes the air shimmer and your skin feel like it’s burning the moment you step outside. Honestly, you could probably fry an egg on the sidewalk.
But as much as you want to admire the way his muscles move under the light, you’re too busy being concerned. Does he even realize how dangerous it is to be out in this heat, shirtless, all sweaty? The sight of him is practically a warning sign for dehydration.
It’s ridiculous—there’s no need to look like that for a jog. You bite your lip, a motherly instinct kicking in that has you more worried about his health than the way his body glistens under the sun.
You lean your hip against the counter, still absently wiping your hands as you watch him run down the street, footsteps pounding with every stride.
And then—he looks up.
You’re caught.
But instead of looking away, he grins—wide, easy, utterly unashamed—and lifts a hand in greeting.
He’s waving at you.
A flash of heat rushes to your cheeks. You haven’t felt seen in so long that it nearly knocks the breath out of you. You’ve been doing this same routine every day for the past fifteen years, ever since you were married off to a man who barely looks at you unless it’s to sigh about something. And here’s this young man, casually passing by and acknowledging your existence like it matters.
It’s been so long since you’ve had anyone truly notice you, like you’re not just a housewife with a fading apron and a tired smile. Your husband always says you’re too overbearing, too needy, always fussing over every little thing, especially with him. He can’t even stand when you try to plan meals or offer to help with anything, like your attention is a burden. It’s not that you want to be overwhelming. You just—well, you wish someone would care enough to notice. To ask how your day’s been. Maybe it’s silly, but the thought of someone actually looking at you, as if you were more than just the woman who makes his coffee or irons his shirts, stirs something in your chest.
You blink, your heart thumping in your chest as you awkwardly wave back, unsure of what to do with the sudden surge of emotion. But just as quickly, you find your hand falling to the curtain, fingers gripping it and pulling it shut with a soft tug.
You’re embarrassed. It’s silly. You shouldn’t feel this flustered over a simple wave from a stranger, but there it is—this deep, sudden awareness of just how little human interaction you’ve had lately. You shut the curtains, hoping the coolness of the room will calm you, but the warmth in your chest doesn’t go away.
The next time you see him, it’s deliberate. You’re outside, pretending to tend to the porch plants, a pitcher of hand-squeezed lemonade sweating on the table. You don’t have to wait long.
“Hey!” His voice is bright, teasing as he jogs up, all long limbs and glowing skin. He leans against your fence without an ounce of hesitation, flashing that same grin.
You clear your throat, offering a polite smile. “You look like you could use somethin’ cold to drink, sugar.”
“Ma’am, you might just be my new favorite person,” he says, his grin stretches wider, like you’ve just given him the best news all day.
You laugh softly, pouring a glass and stepping forward to hand it to him. His fingers brush yours—just barely, but enough that you feel the heat of his skin.
“You always make lemonade for strangers, or am I special?”
You laugh, surprising yourself. “Depends. Do you always charm women on their porches, or am I special?”
His eyes flicker with amusement, like he’s caught a particularly fun challenge. “Oh, I like you,” he muses, reaching for the offered glass. “Satoru, by the way.”
You already figured he’d have a name that suits him. Something playful. A little too bold.
“Well, Satoru, try not to drop dead from heatstroke out here.”
He hums in satisfaction as he sips, then pauses—too close now, leaning just enough to make you notice. His nose nearly brushes your hair before he inhales, long and
“You smell good.”
The words are too casual, too honest. You freeze, pulse kicking up. He doesn’t move away.
“Your husband around?” he asks next, and it’s so smooth, so effortlessly curious, that you almost don’t hear the underlying note of something else.
“At work,” you say, unaware of the way his gaze lingers.
“Kids?”
You shake your head. His grin softens, something knowing in his expression.
“Guess that means you’ve got a lot of free time.”
And just like that, you realize—this boy, this charming, ridiculous man, doesn’t know boundaries at all.
As the days turn into weeks, Satoru finds himself growing increasingly comfortable in your presence. He lounges on your couch, his muscular frame taking up far more space than he should, as you both watch television together. His hand often finds its way to your thigh, giving it a gentle squeeze or a playful pat, always with the excuse that it's just his cultural norm.
One evening, as a particularly intense scene plays out on the screen, Satoru suddenly winces, rubbing his temples.
“Migraine," he grunts, his voice strained with pain. Without waiting for an invitation, he nestles his head into your soft, pillowy breasts, sighing in relief as he feels their comforting warmth envelop him.
“Poor, baby,” you murmur, gently rubbing his scalp to soothe his ‘headache.’ Having no kids and an absent husband means a lot of love to give, and who better to share that with than a man new to southern hospitality?
"Mmm, thank you, y/n," he murmurs, his voice muffled by your chest. "You're so kind to let me rest here." He nuzzles deeper, his lips lightly grazing your skin as he seeks solace in your nurturing embrace. His hands come up to rest on your hips, gripping them gently as he presses himself closer, taking advantage of your natural inclination to care for others.
“Oh,” you gasp as you feel him tuck his nose into your neck and smelling your perfume. This is so far from being appropriate, you’re old enough to be his mother for crying out loud.
And then, he presses a gentle kiss to your throat, humming softly as he presses his weight against you.
“What are you doing,” you ask, trying to keep the shakiness out of your voice as Satoru's hands roam over your curves, caressing and squeezing the soft, womanly figure of your body. He takes advantage of the instinctive tilt of your head, his lips and teeth and tongue exploring the column of your neck with a newfound hunger. A low, appreciative groan rumbles in his chest as he inhales your scent, feeling your body melt against his own.
"It's just a custom where I'm from," he lies, his breath hot against your skin. "Showing affection and appreciation for the ones we care about." He places another kiss, his lips lingering a moment longer this time. His hands on your hips tighten slightly, pulling you a little closer as he loses himself in the comfort and warmth of your embrace. You’re so fucking soft, so warm, so loving.
He tilts his head to look up at you, his blue eyes dark and smoldering with unspoken emotions. Slowly, almost hesitantly, he raises a hand to cover yours on his scalp, guiding it to the back of his neck. His skin is warm and slightly damp from the heat, the dampness seeping through the thin fabric of his shirt.
"You have such a gentle touch," he whispers, his gaze locked with yours. "And such a kind heart. I feel lucky to have you as my neighbor, y/n."
As he speaks, his other hand begins to wander, his fingers tracing idle patterns on the smooth skin of your thigh. The touch is feather-light, almost teasing, but it sends a shiver of anticipation down your spine.
“Sweetheart, we don’t do things like this, okay?” You murmur softly, moving the hair out of his face, trying to ignore the throb between your legs.
“It hurts,” he whines into your neck, slipping between your legs to rock his aching cock against the fabric of your skirt. “Can you make it go away? Please?”
“Baby,” you gasp, trying to catch your breath while he rocks against you, his brows knitted together. “We can’t do this, I’m married.”
"I know I'm new to all this, but I'm a fast learner," he whispers, his breath hot and heavy against your ear. "And right now, my sweet southern belle, I'm feeling a little… lost." He punctuates his words with a roll of his hips, pressing the growing evidence of his arousal against the curve of your ass. "Tell me, beautiful, how do you usually handle such situations down here in the South?"
