Build-Up Begins
Even after Father left for his overseas trip, life with Mom didn't change much. The weather outside was brutally hot, so we mostly stayed indoors. I'd head to the gym in the morning and come back around lunchtime, sticking close to home, while Mom handled housework, reading, or watching TV. But without fail, every afternoon around 3 PM, she'd roll out a yoga mat in the living room for about an hour of yoga or home workouts.
As the heat intensified, Mom's tops got thinner and shorter, and she started wearing short leggings that exposed most of her snowy-white thighs. Watching her walk—her massive tits jiggling, her ass cheeks swaying, those plump thighs rubbing together so tight not even a sheet of paper could slip between them—it was pure torture.... And then she'd do yoga in that outfit. From the sofa, I'd pretend to scroll on my phone or watch TV, stealing glances at her enormous ass outlined through the leggings, the thick bulge of her Y-zone, and the glimpses of cleavage peeking from her loose tee. It only fueled my raging lust for Mom, who was unknowingly giving me such a feast for the eyes.
About four days into this routine, I decided to kick off the first phase of my plan while Mom was, as usual, deep into her yoga.
"Ugh, maybe it's all the strength training lately, but my body's feeling stiff and sore.... Does yoga help with that, Mom?"
"Hmm, yeah? Yoga's great for it~ Since you brought it up, grab that extra mat over there and sit in front of me."
Veterans always take interest in newbies. Mom, with her years of workout experience, jumped right on it. Celebrating my first step's success, I quickly laid out the spare mat and sat in front of her.
"Let's start with some stretching?"
I clumsily mimicked her leg and arm pulls, and at first she coached verbally. But soon, frustrated, she came over to my side, pressing and pulling my body herself to guide me.
"Hahaha, son, why are you so stiff? Bend lower."
"Guh... ngh...."
Her soft hands touching me felt amazing, but my body was way stiffer than expected, and Mom's stretches were intense. The pain of my inflexible muscles tearing apart drowned out any pleasure—I couldn't focus on anything else. As I pondered tweaking the plan to overcome this snag, Mom shifted to help with a forward bend. She pressed down on my back from above... then fully mounted me, pressing her body against mine to push harder.
"Nghaa!"
No way!!
Pain shot from my legs up my back, groans escaping my lips. But amid the agony, I felt Mom's firm tits squishing against my back, her nipples' sharp outline pressing in clearly. The pain started to fade, melting away....
"Hyeonmin, you gotta keep doing yoga with Mom from now on. Your body's way too rigid."
"Ugh... it's not that bad.... Okay, Mom."
The 30-minute stretch session finally ended, freeing me from the ripping pain. Exhausted, I collapsed flat on the mat, sweating bullets.
First step—getting skinship normalized—seemed like a win. Her hands had roamed my body naturally, and she'd pressed her tits and thighs against me.... Though I did wonder if she just saw touching her son as normal....
"There~ All loosened up?"
"Yeah, mostly... but my shoulders still feel a bit tight."
"Then lie face-down on the sofa. Mom'll give you a massage."
"Yessir~ Didn't know you did massages too, Mom?"
"Of course! I even have a certification~"
I flopped onto the sofa, and Mom straddled my ass, kneading my shoulders. Her certified skills weren't bluffing—the relief was incredible. Plus, her crotch ground lightly against my butt, transmitting faint heat, and even through clothes, knowing her pussy was brushing me had blood rushing to my cock, pinned under me against the cushions.
"Feels good, right, son~?"
"Mmm, yeah, Mom... amazing~"
The massage is great, but her pussy lips grinding feels even better!
"Whew, been a while—tiring~ That enough for you? Mom needs to shower."
"Ahh~ Yeah, all good. Thanks, Mom—so refreshing~"
After about five minutes on my shoulders, she headed to the master bath. To hide my raging hard-on, I stayed prone, rolling my shoulders as thanks. Hearing the shower start, I got up and sneaked toward the master bedroom, hoping for a peek. But of course, the bathroom door was shut tight. Mom was careless about going braless or whatever, but locked doors? No gaps....
Then, unexpectedly, on the bed: her pink short leggings from moments ago, rolled up at the edge.
Heart pounding with anticipation, I unrolled them. Inside was her white T-back panties, still warm with her body heat. Pulling them out, the crotch was visibly damp. Sniffing close, I caught her sweet musky scent, a hint of sweat, and the faintest tangy, lewd pussy aroma.
Having Mom's panties right there helped, but just the smell had my half-dead cock surging upright. That filthy, intoxicating pussy whiff pickled my brain in ecstasy—I buried my nose in them, inhaling deeply. My dick twitched wildly, protesting for release. Later, I'd cringe at how pervy I was, but for an incestuous MILF addict, it was inevitable with her fragrant panties dangling like bait.
About ten minutes of frantic panty-sniffing and cock-stroking later, the shower stopped. Pleasure nearly overrode reason, but luckily, sanity reclaimed my brain. I debated pocketing them but decided the risk was too high. Rolled them back into the leggings, placed them exactly as found, cracked the bedroom door, and stood watch from outside.
Hoping for a glimpse of wet naked Mom, but she emerged in a tank top and fresh short leggings. Still hard, I dashed to the sofa, flopping face-down and faking TV interest. Soon, Mom came out, assumed I was still resting, and smacked my ass cheek on her way to the kitchen for dinner prep.
"Still lying there? Go wash up!"
[Smack!]
"Ow!... Got it."
My erection had softened enough, so before she nagged more, I showered quickly and emerged, ready for the next step.
Mom was in the kitchen, apron on, cooking away. I tucked my half-hard cock downward in my panties and snuck up for a backhug. My arms around her waist pressed upward into the heavy weight of her underboobs; downward, my semi slid right into her ass crack. Accounting for our height difference by pointing it down worked perfectly—otherwise, it'd have poked her back or air.
"Eek, you scared me!... What's this? Hugging Mom? Nice from my big boy, but kinda gross, hehe."
"Aw, c'mon~ Need help with anything, Mom?"
"Nope~ Almost done. Clear the table, sonny~"
"Yesss, Ma'am!"
She startled at first but, recognizing it was her son, kept cooking. She had to feel my forearms on her tits and cock wedged in her ass, yet acted unfazed— even teasing about her grown son while shaking her hips to dislodge me. That transmitted the firm, juicy feel of her ass straight to my dick. Despite the surprise backhug, no real pushback—progress on normalizing my touches.
After dinner, I stopped her from dishes, insisting I'd handle them so she could relax on the sofa. Beaming at her dutiful son, she thanked me with a quick shoulder rub and headed over. No lewd vibes (well, her outfit was slutty...)—just her smile had my heart pounding.
I really like Mom a lot.
Finishing dishes fast, I headed to the living room sofa, gearing up for the next phase of the plan.
