Yui and Daiki [pt. III]

*I'm going to try third person omniscient narration here. Normally I stay in the head of just one person at a time, so hopefully this won't be too confusing.

It was early evening on a normal Tuesday in the Obata household. Natsumi Obata was dicing some vegetables at her kitchen counter. She had the sound up on her tablet because the sounds from her daughter's bedroom above were becoming quite the distraction. It didn't bother her much, sex training was such a normal part of a Japanese youth's education. If anything, she was a little wistful that her dear Yui was growing up so fast.

Upstairs and on the other side of the door with the cutesy pastel sign that read: Yui's Room, was an incredibly raunchy scene.

Tanaka's big nude body was laying on the bed with his legs spread as Yui awkwardly perched atop his stomach and leaned backwards over him. Her legs were spread wide across his thighs and the sex trainer's hand held his big prick to her juicy pussy lips. Her boyfriend remained on the floor before them with a perfect view of their impending joining. Daiki's current level of dress was a bit comical, from the waist up he still wore his school uniform perfectly including jacket and tie while below he wore nothing, both his hard dick and firm butt on display to the room.

"Okay! Here we go! I'm putting it inside you." Tanaka declared with enthusiasm.

Yui was breathing hard, her face and chest flush as she stared at his fat cockhead pressed to the entrance of her sex, "Um..Um..you're going to be gentle, right?"

"Of course! I promise to take it slow... sex is going to feel sooo amazing, you'll see."

Tanaka fiddled with his cock, causing its tip to slide a bit through her folds. "It might hurt a bit at first but for your boyfriend's sake, please do your best to endure."

Tanaka craned his head past Yui's shoulder to look at her boyfriend down below. He had to stifle the urge to snicker, seeing him like that. He's so pathetic! "Good Daiki-kun, like I told you, just keep your eyes focused on where my cock is about to enter your girlfriend. You now have permission to jerk off."

Daiki didn't need to be told twice, his hand flashing to his dick and he began a quick furious pumping straight off as Tanaka continued, "I want you to think about what it feels like when my cock is inside her. Watch closely and use your imagination."

"Yea, okay." Agreed Daiki a bit absently, his face flushed red, constantly fapping, "I'm doing it. I'm imagining it."

Tanaka pulled down on her hips as he thrust up with his pelvis, driving his cock into the impossibly tight, hot grasp of her snug little pussy. No matter how many times he did this... this moment was always incredible.

"Look, it's going inside her. My cock is going inside Yui!"

She panted and stared down at the very thick organ splitting her pussy open as it slowly pierced her. For Yui the feeling was akin to having a thick pole of hot meat being slowly stuffed into her, as it ripped open her young folds and spread them wide open, exposing her **** pussy to his size.

"Ah..." Yui gulped, biting her lips as her face contorted in mixed pain and pleasure with every inch that slowly slid into her. It felt amazing and horrible at the same time. She looked to her boyfriend for support taking in his awed face, his hand jerking back and forth over his dick at a breakneck pace, "He's... he's going inside me... ah.."

"Dai- Daiki.... My hymen... he broke it..."

Daiki met her eyes and smiled before quickly directing his gaze back to her genitals, "Y-Yui! He's almost halfway in. You can do it!"

Tanaka was in heaven listening to this couple's cute little interaction as he deflowered the girl. Taking their most precious experience together and stealing it for himself was the greatest feeling in the world! He continued to pump his hips, slowly pushing a little more of his shaft into her with every thrust. The girl was shivering and whimpering, "It... hurts. Daiki... Daiki!"

Then with a wet popping sound he hilted deep inside, burying himself completely inside her. "And there!" he declared gaily as he clutched the sides of her torso and supported her as she screamed out as his entire massive length was completely swallowed by Yui's pussy. The tip of his glans touched the opening of the uterus which delivered a chaste kiss to the blunt cockhead before it **** its way past and up into her womb. Yui wailed and quivered stiffly atop his bulk, feeling the head of his cock bump deeply up inside her stomach.

"Hah...Defloration complete!" sighed Tanaka as he lay back on the bed with a big satisfied smile, the feel of Yui's slight form squirming atop him, her tight pulsating pussy alternately squeezing around his member. This feeling of conquest... There's nothing else like it in this world!

A few moments passed with him content to remain still inside her. Yui was soon laying collapsed back atop him, breathing heavily.

Daiki stared at his girlfriend, her hair a tousled mess about her eyes. She looked sooo sexy, every bit of her body on display. She looked exhausted and out of it just from the act of taking Tanaka's big cock inside of her.

"You are now a real woman." commented Tanaka from underneath her, one of his big hands laying atop her stomach while the other moved to her pussy, "Well done, Yui."

Daiki kept fapping, he'd never stopped, as he watched Tanaka's fingers frame her pussy that was speared open by his cock, "Take a good look, Daiki. This is your girlfriend's pussy. Look how deep inside her I am." Laying back as she was, there were now actually several inches of blood streaked dick outside her outrageously spread petals, the base of a pillar of thickly veined flesh with a well-filled sac attached and draping thickly from it containing two fat testicles that looked happy to let the bed take their heavy weight.

"I'm nearly about to cum just from how tight she is..." commented Tanaka.

"Really?" asked Daiki, stroking his cock non-stop.

"Yea, she's great." said Tanaka before launching into his teacher's tone even while still stuck under Yui, her luscious thighs spread lewdly wide to either side of his dick still ensconced in her pussy, "The vagina is designed to coax a man to orgasm. It's slippery and soft, and it grips you so tight. Ah. She feels like she's burning up inside, she's so hot."

Tanaka's arms slipped up from under Yui's legs, clasping her thighs, "I can never get enough of this!"

Suddenly he lurched up, gathering her legs together and pulling them up so that she was bent upon his lap, her knees pressed to her tits, her pussy still fully impaled on his big cock despite the movement. Her still stocking-ed feet dangled in the air before him, his arms crossed over the backs of her thighs as he began to roughly bounce her up and down, making her scream out. "And then you can start to fuck her like this!"

"W-wait! Ah! I'm not- Ah!"

His furious thrusts were chaffing Yui's drooling pussy raw. The thick member passed through the crease again and again.

"It hurts! It hurts! You're hurting me, Tanaka-san!"

"Y-Yui..." Daiki murmured, his brow furrowed with concern even as he steadily pumped his dick, more than a bit uncomfortable that she seemed to be in pain but he trusted Tanaka and he was just so turned on...

Tanaka paused with her still squeezed tight in his arms, her pussy fully impaled by his huge cock, her juices spilling past it to coat her thighs and his balls, "Hrm. How strange. That's not right because while it is normal for big dick to cause some pain in the beginning, it's actually that good intense 'this pain is so close to pleasure' sort that all women crave. And anyway, it's normal for my cock to always feel amazing to you, Yui. In fact, it would be normal for my cock fucking your sweet little pussy to feel better than anything in your life! Come on, Yui. Normally, all the pain goes away right about now, right?"

With each new use of the word normal the earrings on Tanaka's ears pulsed, their magic sending out a wave of mental energy that swept across those in the room in an instant before rapidly picking up speed, washing across the entire planet in less than ten seconds. It was a subtle effect given the subject matter of the change, preference for penis size not exactly having an immediate impact on a people's everyday lives. But the effect was real and it combined with a similarly themed statement made by dear single-minded Tanaka earlier and in just a few moments it was common knowledge that 'size did matter' and the number of women who definitely had a preference for larger cocks vastly increased. The mental and societal change swept across the world so rapidly that it was effectively instant. Everyone experienced it, from the townships of Africa to the deserts of Australia, from the streets of Beijing to the towns of Belarus. 'Size mattered' and no one could deny it.

It would take time for the ramifications of this change to fully make themselves known but they would include a surge in the sales of larger sex toys, many more men considering surgery to gain a larger penis, a boom in the careers of certain male porn stars, the rise of new 'size queen' websites and a great many broken hearts when men failed to live up to the new elevated expectations of women.

The word 'well-endowed' would quickly become common place and be used to described the male characters in both romantic movies and superhero ones while 'his little friend' would become the standard euphemism used on television and in real life to describe a man of less that impressive endowment. And of course it would always be mentioned if a man was particularly well-endowed, the exact measurement becoming nearly as important as a man's weight or height.

But that was all in the future, most of Tanaka's changes to what was normal actually only affected one person: Yui.

"It's normal that having sex makes you so happy, Yui! That's what you're thinking, right?"

The changes to her mind were quite powerful while the effects on others weren't quite so dramatic given the statement's singular focus. It generally meant that if for some reason a random person were told that Yui's first time with Tanaka had been absolutely fantastic sex that would lead to her really loving having sex in general, they'd shrug their shoulders and say something like, 'Well, yea, have you seen that dude's dick?'

"Haah, ah!? Huh?”, let out Yui as Tanaka's hips continued to bounce her, only moments earlier the sensation of his big thing had been tearing apart her most sensitive areas with a dull aching pain that occasionally went sharp, causing her to tighten her body against it every-time her womb was stabbed. But now that pain disappeared like it had been a lie. Far from hurting, Tanaka's plunging cock felt good, it felt... exciting! She liked it. She really liked the pleasure of being so perfectly filled, so utterly stuffed with her trainer's huge dick.

"Ah, ah, aaah...."

A moan escaped her lips as she pushed her body down into his thrusting prick, eager to have him go deeper. She didn't know what was happening inside her, there was only the feeling of pure ecstasy. She had never felt so happy in her life as she did right now being fucked for the very first time.

I can't believe how amazing sex is!

Tanaka could tell his changes had taken hold as she started clumsily working with him, "Oh good, you're starting to feel good now!" He took a stronger hold of her bent legs and pounded into her harder, enjoying the sight of her cute buns jiggling against his stomach.

"Yes! Ah! Yes!

"See? It's great! Don't you love the feel of my cock inside you?" cried Tanaka as he shifted, laying her down on her side upon the bed as he got up, the length of his member making it easy to change positions without it falling out. They were both covered in sweat, he lifted her leg to get a better angle. Their union was once again perfectly displayed to Daiki on the floor. Her smooth, lightly furred mound bulged outward on the in-thrust and her inner flesh seemed to try and come out during his withdraws.

Between passionate moans, Yui answered him, "T-tanaka! Ah! Yes! Your cock is amazing! Oh oh! I love it. I love your cock!"

She had never felt anything like it before, everything felt amazing! Her whole body was tingling. The feeling between her legs was unlike anything she had ever known; it felt incredible to have a man's member inside her! She opened her eyes and caught sight of her boyfriend still pulling on his dick as he watched her. The look on his face was one of pure lust and adoration, his handsome features flushed red and a sheen of sweat coating his brow. She could tell he was still trying to last as long as possible, but she could also see the joy on his face and in his eyes as he looked at her, the love for her shining through.

He had wanted this for so long, and she was glad to give it to him!

"I'm glad to hear it's giving you so much pleasure!" laughed Tanaka. "It's good you're enjoying yourself. But I need to be teaching your boyfriend too..."

Yui was fine with that. She was perfectly happy just lying here and experiencing the joy of having sex.

"Okay then. Are you listening, Daiki?"

"Yea... I'm listening..." he answered as his eyes feasted on his girlfriend's beautiful body, cataloguing all the ways her soft flesh jiggled and wobbled with each thrust of the coach's huge dick. Her tits jiggled and wiggled erotically as her lower body bucked with each one of his powerful thrusts. He could see her pussy stretching wide to fit his large member inside her, her pink lips gripping it firmly as he withdrew, only to be pushed back in. Watching sex in the flesh was incredible.

"Sex isn't only about your own pleasure. Make sure you're considering her feelings too."

"You can't thrust deep inside her the whole time. Vary the speed and angle of your thrusting. Try out all sorts of things to see what works best. You're looking for her weak points, places that give her the most pleasure."

Tanaka turned her onto her back and he clambered to his feet on the bed while still inside her, going into a deep squat over her as he resumed his thrusts. Her legs were **** up against her body by his weight and the angle of his cock. He reached down and gripped her ankles, holding her legs up and back further, opening her up as he continued to fuck her.

"Ha ha.... and when you find those weak points. You target them non-stop! Haa! Pound into her with your hips... just... like...this!!"

Suddenly Tanaka was putting all of his enormous weight behind his pounding thrusts into her pussy, almost like he was punishing her purposely. It didn’t matter that he was overweight there was nothing silly or comical about him now, his stamina and vitality were amazing. He slammed his colossal hips into her at a ferocious pace, pummeling her unprepared pussy with incredibly powerful thrusts. Rather than a fat otaku, he looked more like an intimidating sumo wrestler to Daiki's eye.

The whole bed was shaking and creaking as he vigorously rammed his dick into Yui and she let out a stream of squeals and yelps with every thrust. The headboard slammed hard against the wall with a loud thud, rattling the framed pictures on the other side.

Tanaka looked over his shoulder at Daiki with a big grin, "Man, your girlfriend really makes the cutest moaning sounds. Am I right?"

Daiki didn't answer as his pre-cum slickened hand schlicked back and forth on his achingly hard dick. He was basically in a daze at this point, he could feel an orgasm approaching. An absolutely huge one thanks to how long he'd had to put it off by now, not to mention the **** stimulation he'd been getting by watching his girlfriend getting fucked so intensely.

"Lastly, I'll be showing you how a girl gets pregnant." said Tanaka mildly as he slowed his pace while continuing to give her long powerful thrusts that seemed to emphasize the size of his balls from this angle as they swung his plunging ass to smack loudly against Yui's butt-cheeks crushed beneath him.

"This is the most sacred of acts. The male cums inside the girl he loves. This is done by couples for the purposes of having a child. Watch closely, Daiki."

"Eh? Cums inside?!" questioned Yui, managing to pay attention to something other than the pleasure of Tanaka's big cock pounding away inside her, "But, I'll have a baby! Tanaka's baby..."

"That's right. But don't worry..." agreed Tanaka as he looked down at her beautiful face which had an expression of
half-shock, half-ecstasy from his dick pounding her tight pussy.

He reveled in the anticipation for one moment. He almost loved using the earrings to control minds and manipulate whole societies as much as he loved fucking tight little virgins in front of their baby-dicked boyfriends! It was almost like he was shoving his great big dick right up into their squishy brains and rearranging things.

"Yui, you'd love to have my baby. That's normal for you. You and Daiki both would take care of my baby as if it was yours! Isn't that, right?"

"Yes! Yes! Oh, god, yes!" cried Yui, quite ready to agree to anything at this point. Daiki was in a similar state not really able to even think about it too much, but it made sense. If Yui got pregnant during their sexual training, of course they'd be the ones responsible for raising it, not Tanaka who would no doubt be getting many girls pregnant due to his duties.

"We have to really do it, or this practice means nothing! Watch closely! When a man decides he's going to get a woman pregnant..." called out Tanaka as he slammed into her again and again.

"Oh! Oh! Oh! Ooh!" she cried as her bouncing tits slapped up and down her torso. She was so absurdly wet now that he thought he could even hear the slurpy squelching noises of his cock sliding rapidly in and out of her even over the sounds coming from her throat and the resounding slaps of his pelvis meeting hers.

"Ah... Yui... Yui..." Daiki found himself softly chanting as he fapped. He was going to cum....

"He pushes the tip of his cock directly against her womb then lets out his semen deep inside her!"

I'm going to do it! I'm really going to do it!

"Ooh! Get ready, Yui!" he shouted as he felt his orgasm begin, "You're going to have my baby!

I'm going to impregnate this girl while her boyfriend watches!

Hands digging deep into her plush thighs, Tanaka let loose. He groaned out loud, his thrusts done but he jerked and humped with his full length buried inside her as his cock-head released a torrential blast of hot baby-making cum deep inside Yui.

For Yui it felt like someone had opened a spigot inside her pussy and pulses of heavy warmth pooled deep in her most sacred place. She'd already came so much and this feeling set off another orgasm that left her bucking like a mad woman.

Daiki grunted and groaned himself, half curling forward around his furiously pumping hand as he
watched Yui, his eyes now more focused as he was brought to the edge by her blissful expression. He let out a long squeal as his own orgasm was reached and he shot his own seed all over the floor and his own hand.

Tanaka sat back on his heels as he surveyed Yui's naked gasping sweat soaked body beneath him, his softening length withdrawing a bit with the movement as copious amounts of his thick white cum came with it.

"That was incredible.", he sighed deeply. "Ha... I came inside you, Yui..."

The rest of his lengthy now flaccid cock slipped out of her. She panted heavily, looking at him shyly with her hands close to her face. Tanaka smirked, thinking to himself that if Yui had been an anime girl she'd have had hearts in her eyes.

Heh. Pussy conquered.

"So, what do you think? Do you know what true pleasure is now, Yui?"

"If felt amazing... Thank you." she answered slowly in a soft even more girlish voice than normal. Something of her normal tone returned as she looked over at her boyfriend, "And... Daiki... you're embarrassing me... You're staring directly at it.."

Despite her words, she didn't close her legs or hide her pussy as it continually released a ton of Tanaka's jizz making an absolute mess of the cover beneath her. Her thighs remained widely spread before his dangling prick.

"So...", Daiki began a little nervously, "That was pretty cool."

Tanaka laughed and got up. But instead of getting off the bed, he clambered over Yui's reclining body and squatted down over her face. Grabbing the head board he carefully lowered his the end of his semen-dripping cock right into her mouth which she accepted without complaint.

After that the training session quickly wrapped up. He had a bit more fun before he was through though. He asked both students to strip down so that he could take some 'official' photos of their bodies.

They were nervous and asked some questions but when he explained that the government required it as a prerequisite for getting their licenses, they went along with it easily enough. He had them stand against the back of Yui's bedroom door and he took some full body pics and then some close-ups of their genitals. Just dick for Daiki while both tits and pussy for Yui. He had a bit of trouble getting it up for the erect shot but he managed it after a couple of minutes of awkward stroking it while Tanaka had an embarrassed Yui strike some sexy poses for him.

Then they all got dressed and it was about time for Tanaka to take off.

"So uh... Thanks for doing this..." said Daiki a bit awkwardly but earnestly as he stood close to Yui, "I know you don't really get anything out of helping me and her..."

Tanaka shook his head, chuckling. This never got old, "No, no.. It's my pleasure...hehe... But keep in mind, we've only just begun, you know."

He did his best to put on a serious face even as he felt his cock start to slither around in his pants as it filled with blood. Man, he was really getting off on just controlling these guys, "Daiki, I want you to make sure you jerk off tonight as you remember what you saw during today's training sessions."

Daiki looked faintly embarrassed but he agreed, "Ah, Okay, sure thing."

"Yui, for your self-study I'm going to need you to film yourself as you masturbate and send me the video."

"Huh?!" Yui squeaked in alarm, her ever present flush returning, "Film myself masturbating?"

Tanaka made up some bullshit on the spot, his cock a steel bar pressing his pants outward, "Oh yea, I need to monitor your erogenous zones."

"O-oh..." she smiled at him as if that made perfect sense, "I- see.."

With that he said his good-byes and headed down the stairs to take his leave.

Yui's mother intercepted him at the door to thank him for his service to her daughter. He chortled on the inside when in the course of her bowing to him, she very obviously noticed the bulge in his pants.

She blushed just like her daughter.

"Erm, well thank you for your time, sir. It sure sounded like my daughter will benefit from your tutelage"

There was definitely a bit of a flirty tone there as her eyes lingered on his crotch.

"Just doing my job, ma'm." he grinned and gave her butt a smack as he stepped past her.
