It was never meant to happen.
For all you know, middle aged men don’t make friends so late in their lives. If anything, it kinda sucks to get a new best friend when you’re way past 45. So, in such absurd context, can you blame yourself for wanting to hop on Harasawa Katsunori’s dick?
If anyone asks you, you can’t tell what prompted your father to forge a friendship with a high school basketball coach, who, for some reason, only wears purple ties. He might actually be too old to find a best friend – aren’t these kinds of relationship forged during the spring of our lives? Yet, ever since the two men met, they’ve been hanging out frequently enough for you to take notice of the basketball coach.
A detached man, neat in appearance if not for his wavy hair, a bit of an enigma, wrapped in a charming face and a body that is surprisingly well-kept for is mature age. You weren’t too keen on approaching him the first time you’ve met. It was in the midst of summer, on a weekend where your dad, looking for some company for a nice barbecue, had his friends and kids over. And there he stood, aloof, standing next to your father with a glace of whiskey. You wondered who that could be – not just because you never met the man before, but also for the fact that it must be some weirdo if he was drinking whiskey in peak summer. And the following month, he’d somehow be there more often than you’d expect.
So much so, even, that you’ve come to expect his presence at your dad’s every time you’ll come for a visit. He’ll sometimes stay over after a drink too much, and you’ll meet him in an awkward encounter in your bathroom. Not one for conversation, he somehow seems to enjoy talking to you. Maybe because to some degree you’ve got your wit and interest in niche subject from your dad, so he might feel like talking to his friend.
And then one day, as your parents went on a trip for the weekend, Katsunori was tasked of house-sitting. Which, obviously, you were unaware of when you came for your regular visit back home. He opened the door, giving you the explanation you were looking for as if he anticipated the fact that your absent-minded father might have forgotten to let you know of his whereabouts. And much to your surprise, he invited you in, because “that’s more your home than mine.” He smiled at you, for the first time ever, on that day. That middle-aged man, standing in your parental home with his tie loosen up and his sleeves rolled up, had you question everything you knew about yourself then.
That was the first time Katsunori Harasawa ever made your pussy throb.
But in all reason, you’d come to ignore that tingling sensation in your panties for the last thing you wanted was to indulge in something who could ruin your relationship with your parents. And for a little while, your strategy worked just fine in your favour.
That was till the following summer came and you accepted an invitation to spend a day at his summer house. You should have been more dubious – he may have been a national athlete in his prime, but could that even afford him a seaside house? And that aside, why were you even invited in the first place? Yet, when he asked you to come in a casual conversation, you couldn’t bring yourself to say no. Again, you should have known better.
Of course, your parents were also convened, and for a moment, that convinced you that everything would be alright, at the end of the day. As foolish as you were, you took it as an indication to let your guards down, enjoying the summer breeze on the terrasse of the villa.
Here you are, spending the day in your cute little bikini by his pool without a single ounce of suspicion in your mind. Hell, you've even shared a few drinks with the man, laying next to him on a chaise longue as you talk about anything and everything.
You can’t lie on the fact that you enjoy your conversations – never shallow, yet not so heavy that they take out all your energy. The words flow naturally as Katsunori teaches you new things about this and that. He is charming and classy, even in the casual air of summer. Linen shirt unbuttoned, letting you see the faint lines of his former muscles and the greying hair on his chest. You've picked on his habit of twisting a lock of his hair around his finger when he gets in reflection, or when the drinks eventually get to him.
It is a nice summer getaway till your parents hit you with the following:
“We should get going. Your dad is working this weekend, and I have prior commitments with my sister” you mum says, as you choke on the white wine Katsunori has poured you.
“Yeah sorry, man” your dad slurs, his childish pout endearing as his time with his friend comes to an end. “Can’t bail on this one, even if I’d much rather spend the weekend here.”
“I get it, it was lovely to have you over for the day.”
You sit there, victim to the daunting feeling of this ending. Maybe it’s the buzz of the glasses you’ve had, or maybe it’s because you don’t want this moment with Katsunori to end. After today, you can’t no longer ignore the obvious – whether that is the shared laughers, the stolen glances, or his hands ever so subtly feeling you under the water of his pool when your parents weren’t looking. Even if you’re visibly enjoying yourself, it will be insane to overstay your welcome.
“I should get going to, then.” You mumble, suddenly getting up your comfortable seat.
“Don’t be silly, honey” your father chuckles, seeing you trying your best to get out of here. “You can’t drink and drive.”
“But you can?” you cock an eyebrow.
“Of course not, your mum’s driving us home.”
“Then I’ll come with you.”
“And your car?”
“I’ll get it tomorrow.”
Katsunori looks up at you, a gentle hand on yours as he urges you to look at him.
“That would be hard, public transports don’t come anywhere near the area. And a taxi fare would go insane, given the neighbourhood...” he reflects.
“Then you’re safer staying over” your dad lets out, looking at his friend. “As long as Katsunori doesn’t mind.”
“No, I could never –“
But the owner of the house is quick to shut your protest. Ever the gentleman, he cannot in his right mind not offer you shelter and let your parents worry about you a minute longer. That’s all there is to it, right?
“Rest up, you can stay as long as you need.”
His reassuring words are enough to soothe your parents worry, as they kiss you goodbye for the night, unaware of what they’ve started by letting you alone, in the warm summer night, with a man that makes you feel things you shouldn’t.
And in a twisted move of fate, here you are tipsy, hot and bothered, in the sole company of Katsunori Harasawa.
The song of crickets resonates in the dead of the night as you swing that glass of wine down your throat, feet digging in the pool while you try to grasp your circumstances and make sense of them, one way or the other.
“You shouldn’t have let me stay” you blurt out, splashing some water in his direction.
He simply scoffs, dark eyes meeting yours in a somewhat judgemental way. You wonder if he ever glares at his players the same, the kind of look that lets you know that he knows better than you think. After all, you’ve gathered already that he is a keen man, not one to do things senselessly.
“I couldn’t let you out there alone, stop being a brat about it.”
You click your tongue, a childish frown on your face as you look up at him.
“Don’t call me a brat. I’m way too old to be one.”
He laughs, sitting down by your side to let his own legs dip in the fresh pool water. The soft sloshing sounds around as he swings his liquor in his glass, before looking at you.
“Kids these days...” he sighs, though you can read a bit of humour in his otherwise stern tone.
“Nuh-huh, mister, don’t give me that! I work a full-time job, and I've developed pain in my back and knees so by all criteria, that makes me a grown woman.”
“I would never question your womanhood.” He replies, gaze falling on your figure.
You have yet to change out of your bikini, figuring out that you might take another dip at some point – even if you really haven’t since this morning. And while you didn’t mind all day, now that you’re in the sole company of the basketball coach, it daunts on you that you are awfully exposed. From the softness of your breasts to the plump of your butt, the length of your legs and pudge of your curves – it all becomes clear to you that he must have noticed it.
And ever the observant man, Katsunori Harasawa isn’t one to ignore a single detail of your body. He’s seen his fair share of women in his life; he’s come to learn what he likes the most. And at this very instant, it’s you. As wrong as it is for him to feel such attraction for his best friend’s daughter, the man cannot ignore the beauty of your being. Something so enticing, that he fights on the daily not to give into his urges.
“Anyway, if we gotta talk about childishness... well, is “childishness” even a word? Anyways.” You down your glass, looking at him with a little quirk of your head. “Aren’t you too old to be making besties with my dad? I know he’s a great guy and all but come on.”
“Well, “besties” isn’t quite like I would put it but he’s a solid guy and I like his presence. Besides, do you care that much? I believe you’re ought to find company at any stage of your life. I might be decrepit to your standards, but my life is not over.”
You nod, swallowing his words. You may be a tad too judgy, indeed: after all, isn’t life meant to be about forging connections and entertaining them till you die? And at the prospect that his life isn’t, indeed, over, you figure that you might in some ways find your place in it.
You stand up, stretching your limbs before starring at the electric blue of the pool.
“Care for a midnight dive? You know, since your life isn’t over and all.”
He raises an eyebrow. As it can be seen in his game strategies, Katsunori isn’t one for spontaneous decision, let alone risk-taking without any insurance that he’s got the tools to pull through. But with you here, he feels the overwhelming urge to dive right by your side in the unknown. He strips down to his boxers – having changed out of his swimming trunks earlier in the day, pulling you with him as you both fall in the water.
For a moment, it’s nothing but the beats of your hearts and the surrounding water. And then, it becomes him – his hand holding yours, pulling you closer, sliding down your waist, getting you to feel him in a way you’ve only ever fantasized about. He’s a hazy form, something between smoke and water, that you grasp with all your might for nothing feels more real than the sensation of his skin.
And when you both go up to breathe, he doesn’t leave you a second before leaning in, mouth dangerously close to yours.
“Wait...” You breathe against his lips.
“Hm?”
“What if it feels like you're kissing my dad?”
All you can hear as a response is an annoyed, old-man grunt, before his lips crash on yours in a wanting kiss. You can’t even feel the ground below you, not even the beat of your own pounding heart – as all your mind can focus on is the softness of his lips and the slow teasing of his tongue. It’s dizzying, worse than the glasses you’ve down already in his company, yet such a sweet sensation that courses your body. Someplace between lust and affection, you’ve met the father’s best friend.
“You say such silly things” he sighs, a small laugh tainting his words.
“I was being deadass.”
He chuckles, pecking your lips as he goes to grab your butt, lifting you up in his arms. Here you are, chest against his, feeling hotter than the sun under his gaze.
“What would it take for you to stop talking nonsense?”
“Aren’t you a smart man? Figure a way to shut me up.”
He smiles, and you look up at him like a girl in love, the droplets from his wet hair falling on your skin as if to cool the burning fire in your soul. Eyes hooded and breath audible, Katsunori, for once, cannot hide away his attraction.
Since tonight is just him and you, he is not holding back the slightest.
You do not protest his experienced hands that wander your body, feeling every curve with such reverence that you can’t tell if your bikini bottoms are wet from the water or your arousal. He’s quick to find the answer for you, a curious finger dipping under the fabric to slide across your folds. He swears, the ever-so stoic man losing composure at the knowledge that he’s got you so turned on. The same finger slides teasingly up, grazing your puckered hole before finding its way back down to your cunt. You hiss, the shimmer of lust in your face encouraging him to take his finger back up, pressing ever so gently against the hole just to see that look on your face again.
“I’m sorry, but I don’t think I’m patient enough to take you to the bedroom” he confesses in your ear, the tip of his finger diving in between the tight walls.
You mewl, not bother in any way by it. You’ve waited too long to be in this predicament, and you won’t waste one more second for the sake of doing things right. Here in this pool is largely enough, as long as it’s Katsunori Harasawa and no one else.
“Fuck, that’s...” you try and fail at expressing the complex feelings coursing through your vein.
“You have such a tight ass” he breathes, trying to somehow keep a lid on his own overwhelming pleasure by peppering your neck and face with languid kisses.
You can’t keep in the sound of pleasure, inevitable result of both his fingers and words, that leaves your lips to join the silence of the night. For a moment, it’s just your needy sighs, the sloshing of water around you, and the cicadas in the garden. And then, he carries you out of the water, laying you on one of the long chairs just so he can admire your gorgeous body under the starlight. He swears, dick painfully hard – you are temptation personified and he cannot resist. He is a man of will, but all of his resolve weakens at the softness of your cunt under his fingers and the breathtaking sight of your pleasure-ridden face. You grab his wrist, hips and legs shaking as he digs at the perfect pace in your sweet hole, way too far gone already to try to control your body.
“I’m coming” you whine, fighting in vain to delay your orgasm. But you cannot claim to be victor against pleasure – it will always be stronger than all logic, all self-control.
It doesn’t help when your lustful eyes fall on his erection. He doesn’t get a say when you pull his cock out, salivating at the mere sight of it. Everything about that man seems to be crafted to perfection, from the girth of his penis to the colour of his tip, so inviting that you have to plead.
“I wanna suck you, please” you purr, doe eyes meeting his so that he can’t say no.
Not that he’d ever refuse you. He groans in the dead of the night when you kiss his head, before giving it the nicest licks from your warm tongue. He’s dreamed of this moment countless of times; every time he stayed at your parental home, knowing that you were in the room down the hall, so close yet so far away. He would lay in bed, thinking of his best friend’s daughter – easily twenty years his junior – those sweet lips wrapped around his cock, the face you’d make sucking him off.
But the real thing, oh fuck...
You are too good to be true, a figment of his imagination. Maybe a hallucination, even, a god-sent being meant to drive him insane. You are everything to him.
“That beautiful mouth of yours” he exhales, watching the way you so adamantly devour his cock, “you’ll kill me.”
You giggle, the sound sending vibrations down his shaft only to make him twitch in the warmth of your lips. Your tongue swirls, nails dinging in his thigh as you wait impatiently for his nectar to flow down your throat.
Oh, how nice would it be, to swallow every single drop of Katsunori Harasawa’s cum...
But ever the gentleman, he cannot allow himself to do such thing. And more importantly, he cannot allow himself to come before he’s even got to feel that heavenly cunt of yours around his dick. He gently grabs your hair, pulling your head away and letting out a soft laugh seeing the childish pout on your face.
“Pretty, can you ride me?”
And on the scale of the things you wish for the most, feeling him inside you might easy be on top. It’s quick, messy, instinctive. You don’t care that you’re taking him raw, a wanton hiss filling the air when his big tip finds its way in your drenched pussy. You hold on to him, swimsuit hanging on one leg as he pulls the top down to feel your breasts. The skin is cold against his scolding touch, a contrast that makes you both insane.
“Shit... I can’t get enough of you.”
Those simple words, as ordinary as they may sound, are enough to make your walls clench. He lets out a strangled moan, fingers digging in the flesh of your ass to bounce you on his cock harder.
“Don’t... ah... don’t clench so hard.” But this time, his voice falls to deaf ears, drowning in the hypnotic song of your whines and whimpers.
You cling to him for dear life, a last fibre of reality to hang out to before you fall completely in a pool of lust. It’s raw, terribly lewd. Oh, your poor parents, so oblivious to what they have done, leaving you alone with that man.
Their sweet daughter, riding the cock of their dear friend like a good slut.
You fail to think straight, mind filled with sex and him. And as much more experienced as he is, Katsunori is not so far from your state of drunkenness. It doesn’t help when you come, whining his name in his ear, the sound raising goosebumps all over his skin.
You’re dangerous, milking his cock with each spasm of your orgasm. He’s not even trying to keep his senses anymore, panting again your skin as he feels his cum travel up his shaft. In a brief moment of clarity, he pulls out at the right moment – the next second, hot ropes of white land on your navel, painting you in him.
To Katsunori Harasawa, you are the strongest yet most delicious liquor ever, and he vows to only ever get drunk on you.
You sit there in your post-orgasm state, looking up to see that the moon has been watching you all along. You blush, embarrassed to have been seen by the stars, but you know they would never tell on you. You look at Katsunori, both knowing that you’ve done the one thing that you can never erase. And yet...
“I might tell your dad someday that I wanna keep you all to myself.”
