Touring the Penthouse – Bed Test Time
“Hurry up!” Ji-na, who had come out of the house first, was jumping up and down, urging us on. It was because I couldn't walk fast while kneading Mom's tits.
Mom was wearing the crop top and short denim skirt she'd bought at the mall last time. Whether she wasn't wearing a bra or it was just that thin, her cleavage was blatantly visible from above. If you stared hard enough from the outside, you could even make out her pink nipples—enough to show just how slutty her outfit was. No bra made it perfect for slipping my hand in and groping. I rested my hand on her shoulder, slid it into her cleavage, and massaged her breast. It was a bizarre sight, you could say, but my little sister Ji-na didn't bat an eye. She just acted impatient that we were going so slow. She showed no hint of weirdness or discomfort at me groping our real mom's tits.
Seolhwa's car was a five-seater. Two up front, three in the back—so we decided to pile into the back row one after another. Me in the middle, Mom on the left, Ji-na on the right.
“Welcome aboard.”
Ji-na opened the car door for us, making it easy to get in, and greeting us was Seolhwa, dressed impeccably as always. Mom was in full slut mode. I was rocking the no-pants, dick-swinging fashion. Ji-na had on shorts like panties that exposed half her ass cheeks, a black bra, and a black see-through top that showed her whole upper body. You didn't even have to try to enjoy her cleavage and flat stomach.
“Yeah, take good care of us today.”
“Of course. Thank you for trusting me.”
“Where are we going first?!”
Ji-na, who had cheerfully pulled aside part of her see-through top to offer me her tits, asked brightly from the side.
“The Taehwaru Building, twenty minutes away.”
“Whoa... I heard that's super expensive...”
“For Min-jun, it's money you can easily afford.”
“Heehee, I'm so glad you're my brother.”
Ji-na draped my arm over her own shoulder, leaned against my torso, and smiled with her eyes.
“Heh, I'm glad you're my little sister too.”
“Heehee...”
At my words, Ji-na rubbed her face shyly against my chest.
“Hehe, it's been forever since Ji-na acted this cute...”
Mom said it with eyes lost in nostalgia, while her tits were getting kneaded by me. In her case, she'd gone ahead and taken off her crop top entirely, baring her upper body. Guess she figured inside the car was fine for stripping—works for me. As I'd mentioned before, Mom looked ridiculously young for her age. Even before I started fucking her—before the “maintenance”—her skin had been flawless, without a single wrinkle. Now that I was taking care of her, she looked young enough to pass for my older sister. And it wasn't just her face. Like Ji-na, she had no excess fat, so no rolls on her belly. For a married woman who'd been pregnant and given birth, she was showing off a smooth, taut stomach, with legs long like a model's. If I didn't call her Mom, anyone would think she was my sister.
And her tits, now fully exposed by ditching the top? They weren't saggy or overly firm—they were soft and jiggly in the best way, yet perfectly shaped and not grotesque at all. The nipples, which Ji-na, my older sister, and I had suckled as kids, were still a pretty pink that made her look even younger, and my handiwork helped.
“Mom, why'd you take your top off?”
“Hm? I figured it'd get in the way if I kept it on while my son groped my tits. Plus, it's nicer to look at, right? Or does my son not like Mommy's tits like this?”
“No way. Mom's tits never get old, no matter how much I touch them. Just kneading them gets me hard.”
“Oh... is that so? Well, good to hear you're turned on. I was worried a washed-up old lady like me might not be enough to handle my son's lust...”
With that, Eun-seong affectionately stroked the hand of her own son that was massaging her breasts. For her, as a mother who wanted to satisfy her son's desires, his words were a huge boost.
“Mom... that's bullshit. There aren't even any young girls with a body as slutty as yours...”
“Hehe, what a charmer. But flattery won't get you anything extra, you know?”
“No...”
Ji-na couldn't let that slide as a fellow woman, but Mom just brushed it off as a joke.
“Hey Mom, I've been fucking all sorts of women outside—rape, paid sex, whatever.”
“That's right. Oof, my son... I was so worried when you were holed up in your room, but I'm glad you're finally living a proper life.”
“Exactly. I was planning to hold out till the end of the year. If you kept being a shut-in, I was gonna pin you down and show you what pussy feels like, no matter what.”
“Oh you... don't say such dangerous things. Raping your own son? People would curse me out if they heard.”
“Ugh... anyway, that's how frustrated I was!”
...
“...Anyway, after fucking that many women, none got me harder than you, Mom. Even setting aside the taboo thrill of banging my own mom, your body, face, tits—everything's hotter. Especially your pussy; it's the best.”
Her son praising her by saying her body was hot, her tits turned him on, her pussy was the best—objectively ridiculous, but Mom looked pleased deep down.
“Hehe, thanks, son. Hearing that from you makes Mommy so happy.”
Mom smiled with her eyes and gently stroked my rock-hard cock. At her soft touch, my dick twitched reflexively, and she cutely gripped it and started stroking.
“Ahh! Me too!”
My little sister let out a whine like her toy got snatched and quickly brought her hand to my dick.
Getting handjobs from Mom and my sister in the car... was pure bliss. And women's tits? You never get tired of them.
We arrived at the massive building, and I stopped the handjob session to get out. Mom slipped her crop top back on, and Ji-na fixed her clothes. Not that it mattered much—Mom's nipples were still visible if you looked closely, and Ji-na's cleavage was right there anyway.
“This is Taehwaru.”
Seolhwa, dressed neatly, guided us. First, we checked out the area around the building. Great accessibility, underground parking plus a multi-level lot—no parking issues. Not that it mattered much to me either way.
Ji-na's eyes sparkled as she wanted to head inside, so I dropped the inspection, flanked Mom and my sister on either side, and followed Seolhwa to meet the building owner.
The owner was a middle-aged lady. She kindly explained the building, pros and cons without hiding anything. Hiding stuff from me to profit would be a death sentence anyway, so no bullshit from her.
“This is the place the secretary wanted.”
We took the elevator, passing quite a few floors. It finally stopped at the 30th. The elevator doors, which had been reflecting me groping the tits of the women on either side, opened to a white metal door.
“We turned the entire floor into a single residence. That's why it's pricey and spacious.”
“Ooh...!”
Ji-na got super excited and started bouncing around. I patted my thrilled little sister's head, then slid my hand back to her tits as we moved forward.
The owner opened the metal door, and now we could take in the interior. White everywhere—tricky to clean but sleek and modern—with black and dark brown accents for style. It was different enough from our old house that I momentarily forgot to grope Mom and Ji-na's tits and asses.
“Not bad.”
Seolhwa gave a curt impression, while Ji-na bounced around. With one hand free, I went behind Mom, slipped both hands under her crop top from the bottom, and kneaded her tits. Her pink nipples poked out, her bare breasts exposed, but Mom—and everyone here—couldn't care less.
I massaged her tits like dough with both hands, shuffling along while groping as I toured. The living room was huge. Big enough for a 50-meter dash. Heh.
“Like it, Mom?”
I asked Mom, who was casually looking around the room while her tits got worked over.
“Gotta check a few things, but the secretary handled it well, I'm sure. No red flags, and I think Mom likes it.”
“Yeah? Is the bed comfy? Can't have it sucking for sex.”
“Wanna test it now? Use Mom's pussy? Or call Ji-na?”
Mom casually suggested we fuck. She brought up incest then mother-son sex like it was nothing, hiked up her skirt, and rubbed her panty-clad ass against my dick.
“...I wanna do it with you, Mom.”
“Hehe, alright then? Lie down on the bed. Mommy'll take care of everything.”
I obediently got my dick hard and lay on the bed as Mom said.
