Chapter 20
"Seobang!!!"
Lee Yeon-seo came running, her massive breasts bouncing heavily as Kim Seok-hun staggered and collapsed while getting out of the taxi.
Ah… Mother-in-law… those breasts… ugh.
His legs burned with pain.
His eyes swam with rapture.
His heart hammered as if it would burst.
It’s… completely hard now.
His cock had stiffened into a full erection.
Her hair whipped in the wind, her eyes filled with heartbreaking worry. Those voluptuous breasts, jiggling violently up and down with every hurried step.
Dear god…
"Seobang…! Are you okay? Why did you collapse?"
At his mother-in-law’s frantic concern, Kim Seok-hun felt his mind spinning out of control. The sight of her rushing toward him was truly…
He let out a long sigh.
"I’m fine, Mother-in-law. I just pushed my lower-body workout a little too hard today, that’s all."
"What on earth did you do to end up like this?! Come on, lean on me right now!"
"Ah… yes, ma’am."
Following her instructions, Kim Seok-hun draped an arm over her shoulder and let her help him to his feet.
As the taxi pulled away, he was quietly surprised by how small and delicate her frame felt beneath his arm.
She’s much smaller than I thought… How can a body this petite carry breasts like those?
With his arm around her, it was obvious. Her shoulders were so narrow that if he simply wrapped his arm further, his hand would brush against the swell of her chest.
"Mother-in-law, where were you coming from?"
"Never mind that! I’m mad at you, Seobang."
"What? Why…"
"Didn’t I tell you to take it easy with the workouts?"
"Well… you did…?"
"Then what is this? You’re really going to make me worry to death."
Her genuine concern left him feeling strangely guilty. Yet at the same time, it warmed him.
It felt good to have someone who worried about him this much.
And it felt even better that the person was his mother-in-law.
"I won’t do it again."
"Really… I don’t know how I’m supposed to live with you constantly scaring me like this. Promise me you won’t do this again, alright?"
"Yes, ma’am. Your wish is my command."
"Are you teasing your mother-in-law now?"
"Hahaha—ugh!"
"S-Seobang, are you okay?"
While trading lighthearted jokes, they tackled the mere three steps leading into the house. His legs gave out again. Yeon-seo gasped and caught him with her whole body before he could fall.
Of course her soft, heavy breasts pressed firmly against him. For some reason, Kim Seok-hun could only smile.
Once safely inside, Kim Seok-hun headed straight for the bed. He collapsed onto it face-down, groaning as he peeled off his clothes while lying down. After a great deal of effort, he managed to strip everything off until only his underwear remained.
"Seobang~~"
Just as he closed his eyes to rest, the sound of her voice made him open them again.
"Yes, Mother-in-law!"
"Can I come in for a moment?"
"Huh?"
Click.
Before he could even answer, the door opened and Lee Yeon-seo stepped inside.
"Oh dear, did I interrupt you?"
"No, it’s not that… haha, I just… my clothes…"
"What’s wrong with wearing underwear? It’s fine."
"I… I guess so?"
Wait a second.
Wasn’t that a little strange, Mother-in-law?
"My late husband used to walk around like that too. Men are all the same. Don’t worry about it."
"If you say so… Is there something you needed?"
"I thought I’d give you a massage."
"A massage?"
Hmm?
A massage? Surely she didn’t mean the kind where she poured oil over her breasts and used her whole body…? No, of course not.
"I learned a bit of sports massage back in the day."
"Ah…"
Of course. What on earth was wrong with his brain?
Kim Seok-hun shook his head at his own perverted imagination.
"It’s been a while, but I think I can still manage a simple leg massage. How about it? Want me to try?"
"Won’t it be too much for you? I heard sports massages are really strenuous for the person giving them."
"It’s not like I’m doing your whole body, just your legs. I should be fine, right?"
Hmm? Mother-in-law?
You said it’s been a while… you haven’t forgotten how, have you?
And if the massage went wrong… well, it would probably be fine.
"Then please do. But don’t overdo it."
"Ho ho ho, don’t worry. Just wait here. I’ll be right back."
"Okay!"
Sports massage, huh…
His mother-in-law was surprisingly well-learned. She had studied cooking, yoga, and now sports massage?
At this rate she might even learn how to use a computer and discover the adult videos hidden on his hard drive.
Kim Seok-hun’s mind wandered into ridiculous territory as he imagined his mother-in-law browsing through his secret collection of dirty videos.
Heh, I hid those folders pretty well.
Little did he know that his mother-in-law had already…
Anyway, while she was away preparing for the massage, Kim Seok-hun blushed at his own absurd fantasies.
His mother-in-law watching porn? Just the thought was strangely exciting.
About ten minutes passed as he indulged in those strange daydreams.
Creak—click.
The door opened again and Yeon-seo reappeared.
But…
"Mother-in-law…?"
"What? Do I look strange?"
"No, not at all. It’s just… you had an outfit like that?"
"Yes. I bought it out of curiosity when I was learning massage. I’m only wearing it now. It’s a bit small, though."
A bit?
That was an understatement.
The top looked ready to burst open at any moment, and the bottom was so short it could barely be called a skirt.
He had told her to wear whatever she wanted at home, but at this rate, how was he supposed to focus on receiving a massage?
"Oh? It’s perfectly natural."
"Pardon?"
He quickly looked down at the stiff sensation between his legs.
His erection strained so powerfully against his underwear that it threatened to tear right through the fabric.
A wave of embarrassment crashed over him, but Yeon-seo simply offered the same gentle smile as before, showing no other reaction.
Natural phenomenon… Mother-in-law, this is entirely because of you!
He knew exactly what this was.
In simple terms, it was the ‘I saw Mother-in-law and got hard’ phenomenon.
I give up…
Kim Seok-hun closed his eyes as if surrendering to fate.
"Let’s see… shall we begin?"
"Please take good care of me, Mother-in-law."
"Ho ho ho. Not Mother-in-law right now. Call me Masseuse."
"Yes, Masseuse!"
The massage from Mother-in-law the Masseuse began in a way that made him wonder if this was truly a sports massage.
First came the sound of liquid pouring.
Squelch—slosh, splatter—
What… what is this texture?
A thick, slippery, slightly cool liquid spread over his entire lower body.
When he cracked his eyes open, he saw Yeon-seo pouring a clear, viscous fluid all over his legs.
Was that normal?
Do they use this much gel in sports massages?
They probably did. But this much? The bed was already soaked.
He would definitely have to wash the sheets after this.
Slosh, squelch, drizzle—
Once the sticky liquid had thoroughly coated his lower body, her hands finally touched his skin.
She started at his thighs.
Her hands began just below the line of his underwear, sliding down smoothly before gliding back up in a repetitive motion. After finishing the front, she naturally moved to the sides, continuing the massage without pause.
"My goodness… Seobang, your legs are so thick."
"Is it too difficult for you?"
"Not at all! It’s been so long that it’s actually fun."
"Haha…"
Whatever made her so happy, the smile never left her face. Meanwhile, Kim Seok-hun couldn’t tear his eyes away from her chest as she leaned forward to work on his legs.
The massage continued from his thighs down to his calves, and eventually reached his feet. That was when an unbearable heat began to rise inside him.
Why?
Because she lifted his leg and rested his foot directly on top of her enormous breasts.
Squelch—press, soft—!
Huh?!
Given how massive her chest was, his foot sank perfectly between her breasts with perfect stability. The toe massage that followed in that position was truly…

I’m going crazy…!!
The soft, yielding sensation against his heel. The gentle touch of her fingers sliding between his toes. And though he couldn’t see it, in this position her panties must have been completely exposed.
Is this… heaven?!
Yes. This had to be heaven.
Where else in the world would a man find a mother-in-law like this?
It was simply too blissful.
After finishing both feet, she spoke again.
"Seobang, can you turn over for me?"
"Ah… yes!"
Since she had done the front, she clearly wanted to do the back. Kim Seok-hun turned over as requested. While doing so, he quickly slipped a hand into his underwear and adjusted his massive, throbbing erection so it pointed upward, pinning it in place.
Once he was lying face-down, her hands began again.
She poured on another enormous amount of oil.
"Since I need to massage your glutes too, I’ll have to pull these down a little."
"Y-Yes?"
"You must have muscles there as well."
"W-Well, yes, but…"
"It’s fine. It’s just your bottom. Besides, I’m a professional masseuse right now."
"Ah… I see…"
When he lifted his hips slightly at her request, she slid his underwear all the way off.
The problem was that she didn’t stop at “a little.” She removed them completely. Still, showing some professional courtesy, she quickly covered his backside with a small towel.
"There. That’s not embarrassing, right?"
"Ah… yes."
It was actually more embarrassing.
What kind of sports massage was this?
The kind he had only heard rumors about… the happy-ending kind? No. He shouldn’t think like that.
She genuinely believed she was acting as a professional masseuse and was approaching this with complete seriousness. He shouldn’t tarnish that with dirty thoughts.
Think about it. If someone got an erection during a Brazilian wax, would it be right to have perverted thoughts?
Exactly. It was the same logic.
He tried to convince himself of that.
Until her hand slipped between his buttocks and inner thigh.
Because she had removed his underwear, the erection he had carefully positioned upward had now fallen downward. That meant she could see it. And if her hand moved just a little deeper, she would inevitably touch it.
Mother-in-law… I’m going to die…!!!
Every time her fingers traveled along his inner thigh and moved inward, an overwhelming, dizzying arousal threatened to drive him insane.
And then—
Slide, slide—
Press, slide—
Tap—!
Hngh!!
Every few moments, her hand would unavoidably brush against his massive cock with a soft ‘tap.’ Each time it happened, Kim Seok-hun’s body grew hotter and hotter.
What do I do…?
How on earth was he supposed to handle this moment?
Meanwhile, in the United States…
"Haa… Once this semester ends, I need to go back to Korea. I’m worried about Mom, and I can’t leave Hyeongbu suffering like that. It’s too pitiful."
Lee Jin-ah, currently studying abroad, had just decided to return to Korea for the upcoming winter break.
"Hyeongbu… Our Hyeongbu, I’m coming to you!!"
