A Father's Duty
The black shadow standing boldly before Ye-jin was Dae-geun.
She hastily straightened her disheveled clothes, greeted him, and tried to hurry back to her room.
“Ah… Father. Were you going to use the bathroom? I’m finished, so please go ahead. I’ll head back to sleep now.”
The moment she tried to slip past him, Dae-geun’s voice stopped her.
“Wait a moment, if you would.”
“Yes? Is something the matter?”
Ye-jin flinched in surprise. Dae-geun’s gaze swept over her body, taking in every detail. The beads of sweat trickling down her neck. The way her nipples poked faintly against the fabric she hadn’t bothered to change out of. And her flushed, heated face.
“Ye-jin. Things aren’t going well with Se-kyung, are they?”
“!!”
The unexpected question made her jolt. She scrambled for an excuse.
“Wh-what do you mean by that, Father?”
“To be honest, I could hear everything from outside. The sounds of you pleasuring yourself alone…”
Ye-jin’s face burned crimson with shame.
“Seeing you like this confirms it. I’m sorry my son has left you in such a state.”
Before she could even process her embarrassment, Dae-geun stepped close, took her hand, and pressed it firmly against the massive bulge in his pants.
“!!! Father?!”
“If my son can’t fulfill his responsibility, then this father must take it on. How about it? You don’t seem satisfied either, Ye-jin.”
She tried to pull away, voice trembling with refusal.
“F-Father! This is…!!”
He gripped her shoulders tightly and leaned in until his lips brushed her ear, whispering.
“I know it’s bewildering, but does the contract allow us to ignore its terms?”
“What…? What are you talking about?”
Dae-geun smiled calmly and explained.
“It was written clearly in the contract. You must assist me with my work and carry out every task I assign without fail. And when my wife and I face physical or bodily difficulties, you are to take care of us by any means necessary.”
“But… that’s not…!”
He cut her off.
“It also states that failure to comply will result in the cancellation of the debt repayment.”
“You tricked us?!”
Ye-jin shoved him back, voice rising in accusation. But Dae-geun simply shrugged as if the claim were absurd.
“I never tricked anyone. You’re the ones who stamped the seal without reading the contract properly. That mistake is on you.”
His expression grew serious. “Society works that way. You should have read every clause carefully before signing. Even after everything that’s happened, you still haven’t learned?”
His words struck true; Ye-jin had no reply.
“Still… we’re family…”
“It’s precisely because we’re family that it ends here. Without me, you would have faced far worse suffering.”
“....”
Ye-jin fell silent. Without Dae-geun, they would have had no money, no roof over their heads. Because of the debt, she might not have even been able to protect her own body.
Well… even if you had read the contract properly, if it was written cleverly enough, you would have stamped it without a second thought anyway.
Dae-geun drew closer again, his voice softening to a gentle murmur.
“I understand how you feel, Ye-jin. But forget the contract for a moment. You’re not satisfied with Se-kyung, and I’m frustrated with unmet desires. Isn’t this a win-win for both of us?”
His solid, powerful frame and the enormous cock straining obviously against his pants stirred something deep inside her.
“But…”
He pressed further, sensing her wavering.
“My wife alone can’t possibly handle all of my lust. You saw us, didn’t you? Our sex. And you became quite excited watching.”
“!!!”
The realization that he had known she was spying on them hit her like a thunderbolt. He knew?!
Shock and crushing embarrassment flooded her body with heat. Thoughts swirled chaotically in her mind—what she should do, what choice would be best. Yet the answer was already clear. No matter how she looked at it, yielding to Dae-geun was the optimal path.
If I… if I’m the only one who sacrifices, everything will work out.
For my husband’s sake, at least…
Besides…
After long internal struggle, Ye-jin finally spoke.
“I understand. I’ll accept your request, Father.”
Dae-geun smiled warmly.
“Wise decision, Ye-jin. Come with me.”
He placed a gentle hand on her shoulder and led her upstairs side by side. They entered the very room she had first spied on through the cracked door.
She hadn’t seen it properly then, but now that she stood inside, the sight left her stunned. A massive bed easily large enough for two people with room to spare. Sensual, dim lighting. The walls displayed an array of adult toys and devices of every kind.
Even someone as unfamiliar with such things as Ye-jin recognized several of them, and there were so many varieties that tension, anticipation, and raw excitement churned wildly inside her.
Dae-geun began removing his clothes. As Ye-jin truly looked at his body for the first time, her astonishment only grew. Those broad shoulders and firm muscles that seemed impossible for a man in his sixties. She had caught glimpses while spying, but seeing him up close was entirely different.
“Ye-jin, take yours off as well.”
“!! Y-yes…”
Startled, she slowly and shyly began to undress. The oversized shirt she wore around the house, the comfortable dolphin shorts, and finally the skimpy panties beneath.
“As I thought, you weren’t wearing a bra under that shirt.”
“It’s more comfortable to sleep that way…”
“Hahaha. I understand. My wife does the same.”
Dae-geun gazed at her naked form with open admiration.
“That aside, you truly have a beautiful body. It doesn’t fall short of my wife’s in the slightest.”
His sincere praise made Ye-jin blush even deeper.
“Though smaller than my wife’s, they’re perky and elastic—youthful breasts. Compared to hers they’re still quite large, and your figure is beautifully toned. My son is truly blessed.”
“!!”
“Look at what your body does to me. I can’t help but react like this.”
Following his words, Ye-jin’s eyes fell on his crotch. His cock was already fully erect, throbbing powerfully and reaching all the way to his navel.
Incredible…!!
She couldn’t help the involuntary surge of awe. The reluctance she felt toward this unavoidable relationship with her father-in-law was still strong. If she could stop it even now, she would. That much was certain. Yet in one corner of her heart, excitement and curiosity raged uncontrollably.
What on earth am I thinking…!!
As if reading her mind, Dae-geun acted at once.
“Ye-jin, come here in front of me, kneel, and suck my cock.”
“What?!”
She hesitated.
“Quickly.”
“Yes…”
Doing as instructed, Ye-jin knelt before him and prepared to take his manhood into her mouth. The enormous cock twitched and pulsed right before her eyes.
Amazing… Is this really the same kind of organ? Look at these veins… It’s completely different from my husband’s…
With awkward, cautious movements she touched it lightly, then gave the glans a tentative lick.
Slurp. Sluuurp.
The cock reacted instantly to the gentle stimulation. When she continued only licking around the shaft like a piece of candy instead of taking it properly, Dae-geun asked,
“Ye-jin. Have you never performed fellatio before?”
“Fell…atio??”
“Fellatio. Oral sex. Have you never sucked cock before?”
“Ah… yes… I’ve hardly ever done it…”
Dae-geun looked genuinely shocked.
“What?! Then what have you two been doing all this time?”
Ye-jin answered bashfully. Until now, Se-kyung had avoided any licking or sucking because he thought it would feel disgusting or dirty for her.
Dae-geun let out a sigh of deep disappointment in his son.
“Aigoo… I understand, but… how can my own son be so ignorant?”
He took hold of her head, guided his cock into her mouth, and began moving.
Uuup!!
“There’s no helping it. I’ll teach you slowly, step by step.”
With the massive shaft filling her mouth, Ye-jin carefully bobbed her head back and forth, sucking with earnest effort.
Uup, slurp!! Juuuuup!! Haaak… uup uup, chuup!!
It’s so hard…!! It’s too big to fit all at once…
“That’s right. Don’t use your teeth. Control your speed and suck carefully. You’ll produce a lot of saliva as you go—use it as lubricant.”
As he instructed, saliva had already pooled heavily in her mouth and was now dripping down her chin onto the floor between her thighs.
“Take it all the way to the root, then when you pull back, tighten your lips firmly around it.”
“Heh (Yes…)”
Chuuuuup~!! Slurp, chululub, chuup, chuap, haaaa… ahk, chuuuuup!!
“After a while, focus only on the glans. Men are most sensitive there. Suck it strongly while breathing through your nose, and occasionally stimulate the inside of the urethra carefully with the tip of your tongue.”
“Haa… haa… Yes…”
Swoong, gup, uup uup. Chuup… chuup…
Ye-jin followed his guidance faithfully, even managing to stimulate the sensitive urethra with her tongue.
“Kkuk…!! Yes… just like that… You’re doing very well. Excellent learning ability for your first time.”
Dae-geun stroked her hair with satisfaction.
His words and gentle touch made Ye-jin’s heart race. Though she had little experience and had once felt strong reluctance toward fellatio, she was beginning to feel genuine interest. Because it pleased him, she found herself growing excited too.
Why… It should feel unpleasant… I should hate doing this with Father…
At some point she realized that while sucking him, her untouched pussy had grown soaking wet from her own arousal.
Why does this strange feeling keep rising? I’m drenched down there too… I should hate it. Why?
Shaking her head, Ye-jin began sucking with increasing greed.
Eventually Dae-geun stopped her.
“You’re doing well, but as a beginner your technique is still lacking. Later I’ll train you until you can make me cum with your mouth alone.”
“....”
Reluctance and excitement warred within her. Dae-geun took her hand, helped her stand, and laid her down on the bed.
“Father?”
He climbed over her, hands caressing her breasts as he looked into her eyes.
“This time, I’ll make you feel good.”
Dae-geun began to explore Ye-jin’s lewd, trembling body.
