AN: thinking about a pervy sex therapist Nanami~

fem reader

You started coming to his home office once a week.

Unsure of it all, in the beginning, you were so nervous. He looked so strict – sitting opposite you in his dark brown leather chair with such a tight expression on his face.

But you came around to like him soon enough.

He was a nice man. Serious but tender with you – putting out freshly baked muffins on the coffee table and always giving you a warm cup of chamomile with vanilla and honey before getting started.

And he was knowledgeable too – had that mature air about him that seemed so polished and proficient you couldn’t help but hang off every word like it was scripture.

When he told you to stop wearing bras because they hinder natural breast growth, you listened, and when he said that keeping your pussy hairless was important for hygienic purposes, you believed him because you trusted him.

He diagnosed you with virgin anxiety and has been so patient with you ever since, helping you overcome it.

Professional enough to practice with you. Sticking a gloved finger inside your pretty pussy when you’re propped on his examination bed, testing out your tightness with words reassuring you that you just need to wait and allow your body to provide the wetness – smiling at you kindly, that way old men do, more with his eyes than his lips, when you’re weeping with slick enough to accommodate all three of his lengthy fingers inside you – squeezing on him so tight.

You gush, shaking your head while spluttering apologies when you cum around them, but he just rubs your clit slowly, with veteran steadiness – telling you it's only natural and healthy for a young woman like you to be so sensitive under a man's touch – that it’s nothing to be ashamed or scared of – on the contrary, it’s something you should feel very proud of.

He’s also kind enough to give you extra sessions – at least three times a week at his home office – sometimes even breaking his own rules, treating you to a house call, coming to your apartment for a nice little chat.

He even assigns you daily exercises for you to do on your own – though he encourages you to call him so he can guide you through it. Instructing you to wet your fingers in your mouth first before you touch yourself down there.

He listens to your little moans filtered through the phone – bated breaths and whimpers as you get yourself all bothered and needy for more.

He tells you to turn on the camera so he can see if you’re doing it right, and you listen – placing the phone in view of your tiny fingers struggling to reach and stuff your cute cunt.

He praises you on your good job – his own camera off, for obvious reasons – he can't have you seeing his raging shaft just yet, or how he jerks it to the sight of your tight little cunt. A deep furrow between his brows and his jaw locked tight, resolute in his plans of coaxing you into giving him your first time. He groans just thinking about it, splurting his load into his fist, listening to you moan for him. “This feels funny, Nanami-san~ Is this right? ~ Please, Nanami-san, teach me~”

He's been coveting your virginity for months now – grooming you – making you pliant and gullible, and soon, all his patience and hard work would pay off.

It’s cute that you don’t know it yet… but your pretty little pussy is all his.

He expertly works it into your sessions as an exercise. One he promises you’ll benefit from. Telling you your condition can be blamed on never having studied a real grown man’s cock – that, because it’s such a foreign thing to you, you end up fearing it.

He reminds you how this is a safe space – tells you that all he cares about is your wellbeing – as he sets himself next to you on the couch, his thick thigh next to yours, while buckling up his belt and zipping himself free – taking his fat erection out for you to lay your innocent eyes on.

“Here it is.” He clears his throat with a rusty sigh, sounding relieved when his manhood springs free, standing proud and fat.

His veins flex along his arm beneath dark blonde hair as he strokes the length lazily – up and down slowly. Making old noises – heavy sighs and hums – dragging the foreskin back and revealing its plush mushroomed head.

You take it in with doe eyes.

“Don’t be shy. Tell me your thoughts.”

You swallow thickly at the assignment, blinking out of your stare. Shocked and embarrassed, though curious, but also a little grossed out – you’re not sure what feeling you end up with. “Uhm- It’s very… big.”

He chuckles low at that. “Come on, you can do better. What else?” He urges you, offering another deep but light-hearted laugh. “You can be honest. It’s a little funny looking, huh?”

“Yeah-” You giggle lightly in return, though you’re still somewhat uneasy – sitting as though you plan on leaving, but staying nonetheless, at the edge of your seat – eyes glued to the chubby member, studying the curve of its spine and the veins forking their way up to its head.

“Feel up to touching it?” He asks, and your eyes snap to his – lined with crow’s feet and something so trustworthy.

But still, you promptly shake your head in embarrassment. “Oh- no, thank you, Nanami-san-” But he’s already taken your smaller hand in his, pulling you back by guiding it to his lap.

“No, no, little one- this is what we've been training for. You won’t get better if you don’t try.” He scolds you, voice both dismissive and reassuring all at once. “Here- feel it.”

He wraps your tiny fingers around the stout shaft and overlaps your hand with his, helping you find the rhythm – stroking it nice and slow.

“There you go, just like that. Good.”

You hesitate at first. Giving your lip a soft bite while thinking about his previous words.

Was he right? Are you scared because you've never looked at or touched a real penis before?

You don't want to be a virgin forever – it's embarrassing as an adult – it makes you still feel like such a silly little girl.

So... if Dr. Nanami says that this will help you overcome your fears, then you suppose...

You'll do it.

You gulp and follow his movement – up and down the large and lengthy pole.

It's so warm – pulsing in your grip, twitching at your soft touch. Skin so thin, almost rubbery, holding something much tougher than you’d imagined.

In your hand, it’s a lot bigger as well. You can’t even reach your fingers around the thickness to touch your thumb.

“All of this goes inside me?” You ask, under your breath – swallowing thickly while he leads your dainty hand downward into the hair around his base, then up to the wet tip, which pilled and trickled with white pearls getting caught between your fingers – warm and sticky.

“That’s right, every inch.” He answers – voice relaxed – pleased by how well you were doing. “Does that scare you?”

You bite your lip and rub your thighs together. “A little…”

“But it makes you feel a little warm, too, hm?” He suggests. “Makes your mouth wet? And also, that soft place between your legs?”

You make a nervous sound, digging your nails into your knee, where you let your other hand rest awkwardly.

He hums again with a soft chuckle. “Don’t be embarrassed, little one. It’s a good thing.” He ensures, encouragingly squeezing your hand underneath his while lifting the other up to your face, brushing a loose strand of hair behind your ear – before sliding it across the back of your neck. “Let's see you be brave and give it a taste.”

You hesitate again – this time a little more decidedly. “I don’t think I can-” But Dr. Nanami is strong, keeping your neck in a pinch as he guides you down into a bow.

“It’s alright, I’m here to help you. Just open your mouth, and I’ll show you how.” He insists soothingly. Spreading his thighs out further while laying your head down on his lap, hips moving languidly when brushing his shaft up between your lips.

It’s so big, so hot, pumping with warmth where you kiss it on the side on a particularly fat and throbbing vein.

He lifts you up slightly and angles the tip into your mouth, creating a cute bulge in your cheek where he rests his hand to keep you down when you flinch at the salty tang getting caught by your saliva. The taste quickly coats your entire tongue.

“Mmh- that’s a big girl~ getting her first mouthful of cock.” Dr. Nanami sighs with a groan, dropping his head back against the couch cushions while pushing up into the pouch of your cheek in lazy thrusts. It strains – makes you feel like it might poke through and make a hole.

He lets it settle there for a moment, enjoying the wet warmth and the unsure movements of your sweet tongue – not knowing where to go with all the space occupied by his meat.

But then he tangles both hands in your hair, gathering it all into a neat ponytail. And, lifting your skull up directly above, he sends his cock down your guzzle even when you whine out in meek protest.

“Breathe through your nose and try your best to swallow it down as far as your throat allows.” He instructs, keeping a tight-knit grip around your hair in one fist whilst the other hand slides down to pet your cheek in soothing circles.

Forcing it down your tight little amateur throat even when your jaw feels like it’s unlocking.

“Good girl.” He sighed once he’d wedged himself in all the way until your lips kissed the pubes at his base.

Your smaller hands dent the muscle of his thigh, offering a meager push. Mewing out a “Mrph-” while you gag around the trunk.

He holds you there, roosting inside your throat for another satisfying moment before easing up, pulling you up by your pony.

You gasp, halfway choked on your spit – but he's not much concerned.

“Stand up- let me feel.” He rushes out in a stiff order, ignoring how you cough and slurp for air – forcing you up to stand between his knees.

His firm hands plant themselves on your hips, being the only sturdy thing balancing you as you wobble – unsteady when he tugs your skirt and panties down until they drop into a pool around your ankles.

He then pulls you onto his lap – seating you with your back leaning against his chest with his cock gliding up through your inner thighs, rubbing against your bare cunt.

You’re still light-headed, bracing yourself against his broad chest while he keeps one thick arm strong around your waist – holding you snug. The other jerks his manhood, tapping it against your clit in soft spit-wet slaps.

“Let’s see how it feels inside you.” He grunts against your ear, resting his chin-stubbled jaw in the dip between your neck and shoulder – looking to where he has your thighs spread over his own.

“N-no, Nanami-san-” You manage to squeak out softly with a voice both teary and hoarse from choking. “Please- I’m not ready-”

But he doesn’t listen – and any struggle you try to inflict ends up aimless where you’re barred beneath his arm – strict and tough with brawn like it’s a seatbelt on a rollercoaster ride.

“I think you're more than ready for it. Trust me.” He’s growling now – so menacingly, you don’t dare speak against it. Only watching the glossy veiny beast with bleary eyes while he rubs through your pussylips with the fat plush bulge topping it – catching your clit and making you gasp before zoning down to your pretty little twitchy hole.

You whine when it’s forced to stretch open as he nudges himself inside the pill-sized opening despite your effort to climb away from it.

“It hurts, Nanami-san!” You cry, but he doesn’t pay it any mind.

“Your virgin pussy will understand it soon. Don’t worry.” He dismisses – continuing to ease his thickness into the tautness, knowing you must be feeling close to tearing apart once his head’s finally swallowed in with a pop, followed by his inches bullying through you one by one, each feeling like a painful mile.

You cry out, nearly screaming, “Please, Nanami-san! Take it out- it’s too much-” worming on his lap, trying to wiggle it out.

But he has you under reigns, and your struggling only results in him sinking inside you faster. Now, so deep you feel him nuzzle against your womb – and still it keeps sleaving itself until it curves against your walls and pudges out in a cute belly bulge.

“We've trained for this. You need to allow your body the time it takes to get comfortable.” He coos, sounding less on edge now that you’ve taken him inside your comfort.

His chest rumbles with satisfaction against your back as he sits there relaxed, bouncing you slackly but not too much just yet.

He keeps you seated but lifts his other arm to tug off your tiny T-shirt.

“Here, let's take this off. It’ll help.” He excuses, and you’re a little too desperate for the relief to refuse – listening to the kindness in his voice and lifting your arms in hope, letting him fling it off.

Only in socks now. You throw your head back and whine when he twists one of your pretty nipples into a sore nub – chest arching from the contact. The arm holding you in place slides a hand between your thighs and starts circling your cute button, flicking over it with a gritty fingerprint.

The friction makes your belly bloom all sorts of colors, making you lock and quiver around that big thing he has nestled inside you, throbbing against your womb as he only gently bounces you on his lap – stretching your little pussy out generously as it suckles him so very sweetly – so very wet, drooling on his lap –squeezing him oh-so-snug.

You feel sticky after a while of twisting and refusing. Feeling so full and feverish. Neck wet from tongue and lips – so wet, spit is running slow trails down your chest, cool in the chilly open air of his home office.

You still think you want to stop, but you’re not as tense anymore – resting prettily against his chest. Moaning for each swirl he does over your budding clit – having quaked with pleasure a whole of three times already, gummy walls rippling all along his shaft as you softly loll your hips on him in return.

There’s a pool of your slick between the two of you – having drooled form where it seeps around the tight edges of where he has you stuffed air-tight, running down his balls to gloss the leather seat beneath.

He takes it as a sign that you’re ready for the real thing.

It’s almost unfair – how easily your smaller body is held in his hands. Maneuvered so effortlessly as he lifts your thighs up against your chest, then spreads them wide.

He hooks your knees on his elbows and braids his fingers behind your neck. It's an awkward position, but you’re completely locked in it. Unable to do a thing except wail with moans once he starts pistoning his fat man-cock up inside you.

It’s way worse when he stands up – bouncing you in the air – holding you folded against his chest, your legs dangling over his arms, jumping as he pounds his meat inside you, stuffing your cunt full on every deep thrust – stabbing your poor stomach until you’re screaming and squirting from the pressure.

Feeling you soak him is the last straw – so tight while spraying a hot mess.

He sits down again, lifting you off his cock before fanning your clit with four fingers – making you gush out every last drop, screaming while raining on his cock until you’ve strangled it out one final time – left shaking.

You’re then ushered down to the floor, on your knees – the top of your head leveled with Dr. Nanamis's big hand, keeping your face forward as he faps his sturdy thickness at your mouth.

“Open your mouth wide.” He orders, his teeth grit while his bulbing cockhead kisses your lips.

You listen when he gives your little head a shake – rolling your tongue out while dropping your jaw for him.

“That’s a good girl-” He praises, placing his tip on the wet bed of your soft pink tongue, giving his cock only a few more tugs before his balls clenched hard and sent a big fat load through his cock out into your pretty little open mouth.

He groans heavily, almost angrily, squeezing every spurt out – some coming out so heavy it spills up your face and down your chin – but mostly getting caught where you have your lips parted to receive it.

“Good girl.” He repeats, taking in the sight of your painted face – so cute covered in his cum.

He smiles.

“Now swallow it all down. And don’t waste a single drop. It's rich in vitamins young girls like you need to become proper ladies.”

You don’t want to close your mouth – you want to spit all of it out and rinse the rest with toothpaste and water. But the hand petting your head is so heavy, you don’t dare. So you swallow. Sniffling at the yucky taste once it sits warm in your stomach, still so sticky and gross on your tongue.

But Dr. Nanami seems pleased.

“Moving forward, I think you’ll benefit from closer examination.” He says. “I've made arrangements to have you institutionalized here, where I can keep a closer eye on you and offer more frequent assistance. You still have a long way to go before you’re well, little one. I’m not close to seeing the results I need in order to release you from my care.”

You’re still too shocked by the former events to look confused, but the sick feeling in your gut just keeps growing.

“Don’t worry. We’ll keep training, and soon I’ll have you turned into a proper little cock-pet.”

You want to run, but after what you’re body had just been put through, aching and screaming at you like it was your fault – you knew you wouldn’t be able to do much more than crawl, and something about the still fat cock resting its weight against Dr. Nanamis thigh told you he wasn’t done with you just yet.

“Give my cock some time to rest, and we’ll try it again later.” He confirmed your fears, still with his hand stroking your head like a pet at his feet. “Meanwhile, why don’t you tell me how your sweet pussy liked losing its virginity- and how this little face enjoyed getting its first-ever taste of cock and cum, hm?”
