A Night at My Friend's House
After that, I started dropping by Jinsu's place pretty often.
Officially it was just to game or kill time, but the real reason was always the same—I wanted to see Jinsu's mother.
Going over to a friend's house wasn't anything strange, so luckily Jinsu never seemed to catch on to the filthy thoughts running through my head.
"Yo! Sejin! Mock exam's over—wanna come crash at my place?"
If anything, he was the one inviting me first.
I didn't feel like going home to my stepmother anyway, so I nodded right away.
"Yeah. Let's do that."
I'd been over so many times lately that Jinsu's apartment already felt more familiar than my own. We punched in the door code and stepped inside; Auntie was waiting in an apron, smiling as she greeted us.
"Son, how was the test? Oh my, Sejin came too?"
"Hello, Auntie."
"Mm. Did you boys already have lunch?"
Even the apron couldn't hide that perfectly balanced milf body. Her face was so young and beautiful it was hard to believe she had a son my age. She looked at us and asked again.
"No, not yet."
It was the day the mock exams finished, so the cram school had let out early. We'd arrived right at lunchtime.
I was starving, and thankfully Auntie offered first.
"Then want to eat with us, Sejin? Auntie'll make omurice."
"Really? Thank you so much."
So we ended up having lunch together. It was the first time I'd actually eaten a meal while hanging out at Jinsu's, and it put me in a good mood. At home it was always delivery food; sometimes I really missed a proper home-cooked meal.
Of course the best part was getting to stare at Auntie sitting right across from me as much as I wanted.
"Thanks for the food~"
I ate the omurice while sneaking glances at her.
I'd thought I'd gotten used to her after all those visits, but up close her looks still made my heart hammer.
She scooped up a big spoonful of omurice and took a bite. Those red lips worked slowly as she chewed and swallowed, then her tongue flicked out to catch a little smear of ketchup at the corner of her mouth… it was ridiculously seductive.
"…Ah."
I just sat there watching her eat, dazed.
How could simply eating look that alluring? I was genuinely jealous of Jinsu for having a mother that elegant. She was nothing like the stepmother who only ever blew cold wind around the house.
"How'd you do on the exam, Sejin?"
"Huh? Oh, this mock was just so-so, I guess."
"Really?"
"Yeah. I'm not exactly the hard-studying type… My stepmother already chewed me out about it."
My stepmother worked as a cram-school instructor.
At our cram school, no less.
Which only makes it more stressful.
Having a stepmother I didn't even like teaching at the same place was incredibly awkward. She always treated me with that cold, prickly, businesslike attitude.
"…Stepmother?"
She must have sensed the complicated family situation from that single word, because Auntie didn't press any further. Jinsu, sitting next to me, was too busy demolishing his omurice to care about the conversation…
"But this omurice is really delicious."
"Is it? Mmm, that's a little embarrassing…"
"No, I mean it. It's really good."
A faint blush colored Auntie's cheeks at the compliment. Something unnameable stirred in my chest at the sight. I suddenly wanted to see her look even more flustered… and right then a perfect idea hit me.
I deliberately "dropped" my chopsticks.
"Ugh!?"
They clattered under the table.
I ducked down naturally to pick them up.
Perfect.
Now Auntie's lower half, sitting right across from me, filled my entire field of vision. That luscious lower body I'd only ever stolen side-glances at was right in front of my face! She was wearing dolphin shorts, so I couldn't see her panties, but everything else was plenty exposed.
Snow-white calves, toes painted with black pedicure, that invitingly spread pelvis and those thick thighs—I drank it all in, then calmly picked up the chopsticks and sat back up with a perfectly innocent expression.
"…"
A quick glance showed Auntie still eating as if nothing had happened.
I'd been terrified she'd notice me staring under the table; I let out a silent sigh of relief.
That was when Jinsu suddenly spoke up like he'd just remembered something.
"Hey, Sejin. You sure you're okay going home like this? You said your stepmom goes nuclear every exam period. Doesn't even feed you properly."
"Eh, it's fine. I'll just order delivery."
Jinsu knew my home situation better than anyone, so of course he was worried.
My stepmother Lee Gyeong-ah's nasty temper was already legendary even at the cram school. If you asked for the three scariest teachers, she'd be on the list every time. And unfortunately, she and I didn't get along at all.
But the way he brought it up now made it obvious he had another motive.
"Sejin, does your stepmother not cook for you?"
Auntie asked with a worried look.
Jinsu answered for me.
"Mom, Sejin's stepmom is terrifying. She's the math teacher at our retake academy—everyone says she's super scary and has a short fuse."
"Jinsu, even so, you shouldn't say things like that so carelessly."
"Whatever. The whole academy already knows."
He smirked at me.
"Just sleep over tonight. If you go home you'll just be stuck alone with your stepmom anyway. Tomorrow's Saturday—crash here. Mom, is that okay?"
So that was why he'd suddenly brought up my family—he'd been building up to the sleepover invitation. Obviously he just wanted to stay up all night gaming together.
I glanced over; Auntie didn't seem opposed. The idea that I wasn't even getting proper home-cooked meals seemed to have hit her pretty hard.
"Sejin, then don't feel awkward—just stay the night? We've got plenty of blankets, and Auntie doesn't mind at all if you're okay with it."
"Ah…"
Normally the offer would have felt too much and I'd have refused. Right now, though, it was irresistible.
Spending a whole night under the same roof as Jinsu's mother?
Getting to share a roof for a night with this unbelievably beautiful married woman was an offer I couldn't turn down. A chance to freely admire that luscious body I'd only ever stolen glances at until now.
I swallowed hard and gave a small nod.
"Then… I'll impose for just one night…"
"Oh, stop with the 'impose.'"
"Yeah, Sejin. Don't feel pressured—just relax and sleep over."
Thankfully neither of them seemed to notice the filthy thoughts swirling in my head.
Evening.
I stepped out of Jinsu's room after gaming and froze.
"Ugh?"
Auntie's outfit was way too extreme. Tight leggings that clung to her lower half and traced every curve of her hips. On top, a bra-top that left her armpits and navel completely bare. I knew it was workout clothes, but on her it set off every dirty fantasy imaginable.
She had a yoga mat spread in the living room and was working on her body. My startled noise made her glance my way.
"…Ah?"
Her eyes filled with fluster; she must have completely forgotten I was here.
So she'd been doing her usual living-room yoga and then run straight into me.
…Holy shit. Insane.
Her body was flushed from the exercise. Skin glistening with sweat looked impossibly seductive. A body so well-maintained it was hard to believe she was in her forties, yet that uniquely ripe, sensual atmosphere still poured off her as she stretched her arms high and held the pose.
At first I thought she'd be embarrassed. Showing something like that to her son's friend was pretty shameless, after all.
But Auntie seemed to decide that panicking would only make it weirder. She kept right on with the yoga poses, pushing her hips back and putting that wide-open ass line on full display.
Good thing I decided to sleep over.
I wanted to keep staring, but if I did she'd notice for sure.
I casually walked into the kitchen and poured myself a glass of water. My cock was already hard enough to tent my pants. I'd been over to Jinsu's countless times, but I'd never seen Auntie in anything this revealing.
The image of her doing yoga wouldn't leave my head.
On the way back to the room I snuck another look at the living room—and of course she was looking right toward me. Our eyes met; I whipped my head away and fled into the room.
Did she catch me staring on purpose?
My heart hammered like I'd been caught stealing.
I jerked upright.
Eyes open, I looked around. What time was it? My hand automatically groped for my phone on the nightstand before I remembered.
Oh right. Not my house.
I'd agreed to sleep over at Jinsu's. The room was pitch dark; it was still the middle of the night.
Jinsu was completely dead to the world after gaming until late.
"…Thirsty."
That must have been what woke me.
I slipped out of the room and headed for the kitchen. I was gulping down cold water when I noticed the master bedroom door was slightly ajar. Auntie sleeping in there…? Without thinking I peeked through the crack.
"Ah…"
There she was, breathing soft and even, deep asleep.
Once I confirmed she was completely out, an unbearable urge surged up inside me. Was there ever going to be a more perfect chance to get a closer look at that beautiful body?
It felt like a devil was whispering in my ear not to waste this opportunity.
Y-yeah… just one look.
I quietly pushed the door open and stepped into the master bedroom where Auntie lay sleeping.
