The Pretty Girlfriend Who Coaxes Him to Put It In ♡
The room was dim, lit only by the soft glow of a mood lamp.
Kang-in lay on the bed, waiting for someone.
Knock knock.
"Senior… I'm here."
"Yeah. Come in."
At Kang-in's permission the door opened, and in stepped Bo-yeon—the academy junior who had been living under the same roof for some time now, taking care of him. She shuffled inside wearing sexy lavender lingerie. The panties especially left almost nothing to the imagination, the plump mound of her pussy standing out in sharp relief.
"……"
Kang-in watched her in silence.
"Don't stare so hard…"
His intense gaze made Bo-yeon's face flush.
"Getting shy now? After you went and told Tae-hoon yourself that you wanted to do it with me?"
"……"
"Come closer."
At his words Bo-yeon approached the edge of the bed where he sat.
"Sexy lingerie again. Is this your taste?"
"I-It's not like that! …I just… these were the only ones left…"
"No need to be embarrassed. I only asked because they look good on you."
He meant it. Bo-yeon's body—small frame packed with full, heavy breasts and a big round ass that stirred a man's lust—suited that kind of underwear perfectly.
"Stand up straight so I can get a proper look."
"…Like this?"
Bo-yeon stood upright, the backs of her hands resting against her hips, arms folded behind her.

"Pretty."
"Euh…"
The unusually gentle praise from Kang-in only made her more flustered. She looked away, thighs pressed tightly together.
"Come sit here."
Pat pat.
He lightly tapped his own thigh.
"…Okay."
Bo-yeon climbed onto the bed and settled astride one of his much larger legs. Her soft, plump ass cheeks squashed against the solid muscle of his thigh.
Grab!
Kang-in's big hand clamped down hard on one full cheek of the ass sitting on his lap.
"Haah…"
"Your tits and ass really have gotten bigger. Am I right?"
"Yeah… haah… y-you're right."
She had already been planning to buy new lingerie soon for exactly that reason.
Knead knead ♡
"Hik… ahhnn…♡"
The large male hand that had been groping her ass now moved up to squeeze her breasts through the lavender bra, and Bo-yeon's body twitched and jerked.
"Sensitivity's better too, huh? You were already slutty, but your body's gotten even more lewd."
"Lewd…"
"It's fine. Guys love a body like this."
As if to prove the point, Kang-in's massive cock was already straining against his underwear, pushing the fabric out.
"Touch it with your hand."
"…Okay."
Bo-yeon reached out and pulled his underwear down.
Throb!
A superb male cock—flawless in both shape and size—sprang free. Thick, long, dark, and ridged with angry veins, it radiated raw, animal power.
"…Gulp."
Bo-yeon swallowed hard. The cock was furious. She couldn't pretend she didn't know why—her own short little body with its oversized ass and heavy tits was the very thing stoking his breeding instinct.
She stretched out a small hand toward the hot, throbbing shaft.
Grab.
Hard, manly cock… so big and strong-looking…♡♡
She was the one who had made this powerful male so hard. The thought came unbidden: a female born into this world ought to take responsibility and soothe a cock like this.
Stroke stroke ♡ Stroke stroke ♡
Just as he had taught her, Bo-yeon wrapped both hands around the pillar of his cock and pumped with firm pressure.
"You've learned well. Feels good."
Kang-in stroked her hair.
"Senior… you're acting weird."
"I'm weird…? How?"
"…Different from usual. …Kinder, I guess."
"Because you've been such a good girl."
"…Me?"
"You've been doing everything for me—meals, housework, all of it. I think that's why I'm recovering faster too… I really am grateful to you."
"R-Really…? Hehe…♡"
Bo-yeon was weak to praise. Especially when it came from her usually prickly academy senior.
If he talks like that I just want to do even more for him…
Feeling good, she worked her hands even harder, caressing his cock. In a corner of her heart a little desire stirred—she wanted more of that praise.
Squeeze squeeze ♡ Squeeze squeeze ♡
"That's enough."
Just as pre-cum began to drip freely, Kang-in stopped her.
"Time to take the lingerie off too, yeah?"
"Okaaay…"
She stripped completely naked and sat on his thigh again, this time with her back to him, legs spread wide.
"You can lean back more."
When she settled against him she felt the hard wall of his muscular chest.
A solid male body… so cool…
The same gallant male who had protected her in the dungeon and even risked his life to save her. Nestled in his arms, Bo-yeon the woman couldn't help feeling an overwhelming sense of safety.
Throb!
"Nngh…"
Between her spread thighs the erect cock rose high, pressing against the cute little swell of her lower belly.
"Suck!"
"Hik?!"
Kang-in pressed his lips to the smooth nape of her neck right in front of him and sucked hard. The sudden stimulation made the tension drain from Bo-yeon's waist.
"S-Senior… if you suck that hard it'll leave a mark…"
"It's fine. Tae-hoon already gave permission, remember?"
He pulled his mouth from her neck, took her chin, and turned her head so he could whisper against her ear.
"So just relax and enjoy yourself right now. Got it?"
"…Yes."
Under his gentle lead she nodded as if entranced. Reading the desire in his gaze, she offered her lips.
"Chuuup─♡"
Her moist, plump lips parted and his tongue pushed inside.
"Nngh♡ Chup… chuop♡ churup♡ lick lick♡"
Bo-yeon didn't refuse; she eagerly tangled her tongue with his.
"Gulp♡ gulp♡"
She shared the same lover's kiss she usually gave her boyfriend—only now it was with her academy senior—and she swallowed every drop of saliva he fed her.
"Nngh… choop♡ haah…♡ hek, hek…♡"
"How about getting on all fours now?"
"…Yesh♡"
Still panting from the sticky deep kiss, Bo-yeon obeyed and dropped onto her hands and knees on the bed. Her big breasts spilled out to the sides. For the tall Kang-in she carefully kept her knees together and straightened her calves, lifting her ass high—just the way he liked.
"You get into position without even being told now, huh?"
"…Because Senior taught me♡"
Of course she did; he had fucked her in this exact pose plenty of times already.
Still… this position is still so embarrassing…
The vulgar shape of a bitch begging a male to mate. And today, for the first time, Bo-yeon was having sex with Kang-in purely to satisfy her own lust instead of her boyfriend's. Her heart hammered wildly with the thrill of willingly cheating and the anticipation of the pleasure to come. Asking him to wear a condom had been her last scrap of conscience.
Rub rub ♡
Kang-in settled behind the doggy-style Bo-yeon and rubbed his cock against her plump pussy.
"Nngh…♡"
Her cunt, already hot and hypersensitive, leaked love juice from the lightest touch.
Cock… that huge cock that reaches all the way into my belly…♡
Bo-yeon's breathing grew rough.
Rub rub ♡ Rub rub ♡
"Nngh, euh, ah…?"
Even with her pussy dripping like a faucet right in front of him, Kang-in still didn't push in.
Why? Why won't he put it in…?
Her body, craving the seed of a superior male, couldn't fight its instinct; she swayed her big ass left and right, begging the cock—yet Kang-in's attitude never changed.
"Senior…"
After more than a week without sex, Bo-yeon was aching with frustration. She couldn't hold back any longer and twisted her head to look at him.
Kang-in saw her face and gave a small smile.
"If you want something, you have to say it properly, right?"
"……"
He meant she had to ask for sex out loud.
Not just to Hoon… I have to say it to Senior too…?
It was hideously shameful for a woman. But the lust of her lewd body had already climbed past that shame.
"I want to… I want to have sex with Senior…♡"
When she used her hands or mouth or breasts there had at least been the excuse of nursing him. This was different. She was simply begging a big-cocked male for a hard, raw fuck to satisfy her carnal hunger.
"Good girl."
Push…♡
"Nngh♡ oooh…♡"
The massive cock parted her pussy lips and slowly sank deep.
Schlick─♡
"Ohoh…?♡♡"
Bo-yeon's body trembled.
It's completely different from usual…
Nothing like his usual rough thrusts. A slow, gentle piston that scraped every inch of her vaginal walls on its way toward her womb.
It's strange… but it still feels so good…♡
Caught off guard by the sudden reverse charm, her pussy clung greedily to the proud thick cock.
Thud ♡
"Ouh… nngh, aaa…"
At last the fat glans kissed the entrance to her womb.
"All the way in."
"Haah… hooh…♡"
The tingling pleasure of his cock gently pressing against her uterus sent a shiver down Bo-yeon's spine.
What is this…? It's weird… it feels too good…♡
Even just sitting still with his cock buried inside her, the sheer size and heat made her feel like she was melting.
"Your pussy's squeezing me tight even though I'm not moving. Feel good?"
"I-It's not like that…"
"Really?"
Press ♡
"Nngooh…♡♡"
He pushed his hips forward just a little, sticky pressure against her womb, and her ass couldn't help trembling.
"You can be honest today."
"…It feels good. Gentle sex feels so good…♡♡"
"Cute."
Pleasure and security filled her at the same time; as a female she felt supreme happiness.
"Shall we check how deep my cock is?"
His large hand settled on the little bulge protruding from Bo-yeon's lower belly.
"I'm going to touch you, so you tell me yourself where my cock is."
"Ah… okay…"
Skewered on his cock and completely disarmed, Bo-yeon answered without thinking. His hand, resting just above their joined bodies, slowly stroked upward along her belly as if mapping it.
"Here?"
"W-Way higher…♡"
"Then here?"
"A little more…"
"Here?"
His hand moved in tiny, teasing increments. If her boyfriend with his tiny dick had tried the same thing it would have been over in seconds, but Kang-in's hand had to climb a long way.
"I get it now. Right here, yeah?"
"Yes. That's the spot…♡ Where Senior's cock is touching…♡"
"Looking at it like this, it's even deeper than I thought."
In truth the whole act was little more than playful foreplay. The belly stretched by his massive cock was clearly bulging; anyone could see it with their eyes alone.
Stroke─
"Hyeuk…?"
Kang-in's hand caressed the protruding lower belly pushed out by his cock.
"How does it feel when I touch it?"
"I-It feels weird…"
"So not bad, then."
Rub rub ♡
"Then above this must be your womb."
"Ahh… S-Senior…?!"
"Judging by that reaction, I was right."
Presss ♡
His big hand gently pressed down on the spot where her uterus sat, then began to rub in slow circles.
"Ohh…?! W-Wait a second… that feels weird… hiiiiih?!♡♡"
Already hypersensitive from the cock filling her, Bo-yeon couldn't hold back when he started massaging her womb from above through her belly.
Squirtt! Squirt!
Still impaled on his massive cock, she gushed a flood of girl-cum from her pussy.
