Training My Friend's Mom's Asshole
"N-not there...♥"
Auntie nudged at me with her heels, trying to push me away. But with a voice and expression already melted into surrender, the protest was useless. If anything, her pussy was gaping open, dripping slick and practically begging for whatever came next.
I gripped her ass hard and spread it wide. Her secret little asshole lay fully exposed — the kind of sight that would make anyone flush with shame. I buried my face between those cheeks and pressed my tongue against the wrinkled ring.
"Hyaaaah!!? No, Sejin!! Not there!! If you lick that filthy hole..."
"Auntie... slurp... slurp..."
Nothing she said reached my ears anymore. All I could think about was that secret, filthy hole she so desperately wanted to hide — right there in front of me. I sealed my lips over her twitching asshole and started to suck.
Of course, I only dared because I knew her hole was cleaner than anyone's.
She'd once told me that every time I sucked her pussy, her rear end came into view — so before I arrived, she always cleaned herself thoroughly enough that her asshole was ready for use. At the time, it had just been her way of saying she kept herself that clean. She clearly never expected me to put my mouth on it for real.
"S-stop! It's dirty! Hyaaaah!!?"
"Slurrrp! Schluup! Schluuup!!"
At first her asshole had been clenched tight, but it couldn't hold out forever. The tension began to ease. I didn't miss the moment — I stiffened my tongue and started prying her open.
I licked gently around the folds, like knocking on a door, and her tightly shut anus gradually loosened. The tip of my tongue slowly began to push inside.
"Nnghhoooh!!?! Your tongue's going in!!! It's going iiiin...♥!!!"
Auntie collapsed onto the yoga mat, screaming with a mix of shame and humiliation. The sheer taboo of her son's friend licking her back hole was flooding her with a pleasure she never could have imagined — spit trailing from both ends of her.
Her springy little asshole squirmed around my tongue like it was welcoming the visit. As a first-time gift, I swirled my tongue deep inside, and I could feel her rectal walls wrapping around it, twitching and trembling.
Good — at least it's not dirty.
Auntie's ass, always so carefully maintained, carried a clean, pleasant scent. She must have deliberately kept her anus spotless just in case it might be seen while I was eating her out. Thanks to that, I could pleasure her back hole without a single reservation.
Fortunately, her asshole seemed to be one of her weak spots too.
"Looks like your asshole is an erogenous zone. Schluuuurp... mmm... Auntie's asshole... I'll make you feel good... slurp. Bleh..."
"S-stop... pull it out already..."
She twisted her body like she hated it — but her asshole clung to my tongue with sticky insistence, as if begging me not to leave.
As I worked my tongue through her already-softened rear hole, a thought crossed my mind: a married woman's well-used asshole might feel pretty damn good in its own right.
I pulled my mouth free and planted a wet kiss on her pink, chrysanthemum-tight anus.
"Hyaah!?"
"Alright. Start relaxing your asshole for me..."
I coated my finger thickly with her juices and slowly pushed it into her anus. Her already-loosened hole sucked it in with a wet little schloop, no resistance at all. Worried she might be in pain, I glanced at her face —
"Hyaaah♥ Haaaahng....♥"
— and found her face flushed with vulgar heat, squirting from her pussy.
So her anus really was an erogenous zone. Reassured, I pushed my finger all the way in.
"O-ooh.... This is pretty incredible."
I couldn't help but marvel at the sticky, clinging grip of her asshole around my finger. If it squeezed this hard on just a finger, how tight would it feel around my cock? But that was for another time. Right now, the priority was developing her asshole.
I carefully started moving my finger.
Thanks to the generous coating of her juices beforehand, it stirred her rear without any trouble. The heat inside her asshole felt hot enough to burn.
"It's insanely hot in there."
"D-don't say things like thaaat!!"
Still embarrassed, Auntie buried her face in the yoga mat and shouted. But contrary to her words, she was lifting her hips high so I could work her asshole even better.
Seeing that shameless lewdness she couldn't hide, I smiled and asked,
"Does it feel good having your son's friend finger your asshole? Your anus is really clamping down on my finger and won't let go."
"Nngh... don't ask me that."
"Answer me!"
SMACK!!!!
I brought my hand down hard on her ass. Auntie jerked her head up in shock.
"S-Sejin! What the hell are you doing!"
"Just checking something real quick."
Smack! Smack!!
I kept spanking her, hard enough to leave my palm prints on that pale white flesh. Each time she screamed in pain — but her pussy gushed like a flood.
I'd suspected it whenever she seemed to secretly enjoy being handled rough. Now I'd found the filthy masochist sleeping inside her, and I smiled to myself.
"You... Sejin, you... seriously!"
Auntie frowned at me, but unmistakable excitement was swirling underneath. Honestly, saying that while squirting pussy juice wasn't exactly intimidating.
What I wanted was to awaken the filthy, masochistic nature buried inside her.
Smack! Smack!
Before long, my handprints were stamped across her ass. Tears had gathered in her eyes from the pain as she glared at me.
"Keep hitting me and Auntie's gonna get mad, you know?"
Schloop...♥ Schloop...♥
But saying that while her springy asshole lovingly sucked on my finger didn't carry much weight.
The humiliation of being dominated by her son's friend — so much younger than her. The degradation of being dragged into the dirt, and still finding shameful pleasure in it. I'd clocked the true nature of this masochistic married woman, and I smiled.
"Auntie.... No. Jeong-ah."
"Nngh!?"
The moment I used her real name, Jeong-ah looked at me in surprise. I gently stirred her asshole with my finger and asked,
"The second I said I was coming, you waited with no panties and your legs spread... How do you think Jinsu would feel if he found out his own mom is this much of a pervert? If he knew our Jeong-ah loves having her asshole licked, he'd be devastated..."
"Nngh. If you keep saying things like that..."
"If I keep saying things like that, what are you gonna do about it?"
I muttered it as I shoved my finger even deeper into her rear. At the sudden increase in speed, Auntie lifted her head and let her tongue hang out.
"O-ohgohk...♥"
"You pervert who gets off on having your asshole fingered! Don't act all high and mighty while you send your son on errands and secretly offer up your asshole at home!"
"S-stoooooop!! Don't say that while you're digging around in there!!"
Jeong-ah was practically crying, squirting juices from her pussy. Especially when I curled my finger and pressed the inside of her asshole toward her pussy, she let out a shattered scream. Before I knew it she'd taken three of my fingers, and she grabbed my arm, begging in a tearful voice.
"S-stop! Please, just one finger♥ Pull your fingers out already..!! Hyaah!? My head's going crazy...!"
"Don't you dare give me orders!!!"
"Hngiiih!!?"
I spanked her until her ass turned red, and she clenched her asshole and came lightly on the spot. She must have felt it intensely from the degradation — her pussy was trembling. And I, too, felt a strange sense of conquest and pleasure from degrading this normally so proper, so refined auntie.
She still felt resistance toward my behavior, but she was such a natural pervert that given time, she'd come to accept the masochist inside her on her own.
Just imagining Jeong-ah offering herself up on the street whenever I ordered it made my cock throb. And so I was already laying plans to turn Jeong-ah into my personal slave.
"S-Sejin, you... seriously...."
Auntie glared at me and muttered in a completely drained voice.
Watching her, I pulled out my phone and started dialing a number. Jeong-ah looked at me with a nervous edge in her voice.
"Who are you calling?"
"Jinsu. Wonder where he's gotten to by now."
I called Jinsu and switched it to speakerphone.
Rrrring.... Rrrring....
The outgoing tone blared loud through the living room, and Jeong-ah swallowed hard. She seemed to have a rough idea of what was about to happen — and even so, her pussy was still dripping slick.
"Hello? Why'd you call?"
At last, Jinsu picked up, his voice puzzled.
