"Ah♡♡ It's too much♡♡ ...I can't take any more♡♡!"
My beloved writhed on the bed in our "married couple's bedroom," her legs spread in an M-shape, moaning in ecstasy.
Semen, freshly shot from my cock, dripped from her hairless flower garden. This was my third round.
I had grabbed Minori-san's silky black hair like a horse's reins, still connected, and led her upstairs to the bedroom. There, I made her stand facing away from the bed and thrust into her from behind for my second internal ejaculation.
Without giving her a moment to rest, I pushed her down onto the bed and delivered a final thrust in the missionary position before finally catching my breath.
My partner, slightly wilted and head drooping, dripped fluids from its slit.
"Haa♡ ...Haa♡ Master♡♡ ...Minori... I'm gonna die♡♡"
My stepmother sat there, her expression dazed, her body trembling slightly.
My arousal was beginning to subside, and it was probably time to call it quits...
"Hey, Minori."
Something on the side table caught my eye.
She'd laid out a crisp white tablecloth to make it easier for me to find, and on top of it were arranged two "toys."
"What's the meaning of this?"
I knew very well what these toys were for.
It wasn't because I'd used them before, but because I'd seen them countless times in videos.
Adult toys.
One was likely the vibrator we'd bought together, meant for vaginal use.
The other was a string of beads, like a skewer of pearls.
They were called anal beads or anal pearls.
"Ah♡ You found out...♡"
After saying it so bluntly, my stepmother flashed a bewitching smile across her sweat-drenched face.
Her beautiful decolletage was also drenched in sweat. The scent of her pheromones, usually so suggestive, was even stronger than usual, making this thirty-something married woman even more alluring.
She was like a bottomless swamp, becoming more captivating the deeper you sank into her.
"You want me to use this?"
"...Will you use it?"
Her eyes, glistening with anticipation, fixed intently on me.
"There are two of them. Which one do you want me to use?"
In response to my question, my stepmother turned onto her stomach, arching her sweat-soaked hips high into the air.
"This... this hole♡"
She spread the flesh of her buttocks with a peace sign made of her own fingers, revealing her rear entrance—the anus.
"Huh..."
Last time we were browsing adult toy websites together, my stepmother had spoken about it as if she'd already tried something like this.
These anal beads might be something Minori-san bought for herself to masturbate with her asshole.
To think she'd grown bored of masturbating vaginally and started developing her rear hole too. It's a little... unsettling.
"Have you ever done anything with your anus before?"
"...Yes, Master♡"
Minori answered, wriggling her massive hips bashfully.
"Did you buy this toy yourself?"
"Yes, Master♡ I bought it... to use myself...♡"
That's exactly what bothers me.
She kept this lewd behavior a secret from me.
"I'm so sorry...♡ Minori is supposed to be Master's exclusive sex slave♡ I shouldn't have secretly played with my asshole♡ Please punish me...♡♡"
"Minori, you're truly an incorrigible slut. You're just using 'punishment' as an excuse to make me help you masturbate your asshole, aren't you?"
"Ah, Master! I'm so sorry for lying! You're right, Master! Minori... I'm just a perverted masochistic married woman who craves to have her asshole fucked raw! I can't take it anymore! Please... take my ass... my ass pussy... and ravage it until it's a mess!"
At this moment, I pause to consider.
The trembling anal before me, twitch... twitch..., radiates pure frustration and desire. I'm intensely curious to see how my stepmother will react if I torment this hole of hers.
But simply granting Minori-san's wish outright doesn't quite fit the Master and sex slave dynamic.
I want something more humiliating and shameful. Something like... for example...
"Do it yourself."
"...Huh?"
"I'd like to see you masturbating with a toy in your anus, Minori."
"My... masturbation...?"
Minori-san glanced between my face and the toy on the side table, then nodded slightly.
"...Understood, Master."
She accepted it remarkably quickly.
"Please observe my anal masturbation, Master♡"
Still in the leopard-like pose, facing away from me, my stepmother picked up the bottle of lotion beside the toy.
She dripped a small amount of the thick, viscous lotion onto her left palm, then guided her hand to the deep crevice between her massive buttocks.
"Ah♡"
A soft moan escaped when her hand touched the narrow opening of her anus.
Even in an area not typically associated with sexual pleasure, it seemed my stepmother could still feel intense sensations.
Her index finger meticulously spread the lotion, ensuring every wrinkle around the slightly brownish hole was thoroughly coated.
With each movement of my finger, her anus would clench tightly, visually demonstrating its remarkable tightness.
Before I knew it, I was leaning forward, staring intently at my stepmother's anus.
So erotic.
This woman's face and figure were already so erotic they struck a primal chord in me, but I never imagined her anus could be this arousing.
Minori-san, her rear slick with lotion, swayed her hips provocatively, flaunting her glistening hole at me.
"Master♡ I'm about to insert my fingers into your anus♡"
Turning slightly toward me, her cheeks flushed, Minori-san panted.
I was too captivated to respond, my gaze fixed on her long fingers as they rhythmically stretched her anus and its wrinkled folds.
"Minori's anus...♡ The lotion has soaked in so thoroughly... Look!♡ See?♡"
Squelch♡
Pressing lightly on her rear entrance with the pad of my finger and then pulling back, the lotion formed a lewd arc.
It made her anus look as slippery as if it were coated in love juice.
"Minori's ass pussy is so slick and sticky, just look at it ♡ From now on... I'm going to use my fingers to... dig around inside ♡ I'm going to... anal masturbate ♡"
"U-um... okay..."
Even though I was the one who ordered her to do this, my stepmother has completely taken control of the pace. I feel like I might start drooling if I'm not careful.
I've fucked Minori's pussy countless times, so I know how it feels when it's wet and how tight it is, but this hole is an entirely new frontier.
I wonder how Minori's anus will move... and how exactly it will make me feel good.
My unflagging lust stirs at the prospect of new pleasures, and my lower body is rock-hard, steel-like.
My stepmother, a sexual monster like myself, glances down at my state, her moist eyes narrowing into a smirk. They're the eyes of a predator, a carnivore.
"Haa♡ Before Master's sturdy cock plunges deep inside me♡ I'll make sure to soften you up properly with my fingers, you know♡"
Minori-san spoke in a voice so syrupy-sweet and high-pitched it made me want to roll my eyes—a stark contrast to her usual crisp, bell-like timbre.
Then, with deliberate slowness, she pressed her neatly trimmed index finger against her anus. Moving it back and forth like a centipede, she began to gradually invade her own depths.
"H♡ Ahh♡ Asshole♡ It's... it's going in♡ Anh♡ So embarrassing♡♡"
Her finger, still dripping with white, viscous fluid from the secret place I'd filled multiple times with fresh seed, now probed the forbidden territory slightly above. With repeated motions—digging at the entrance like a shovel turning soil, massaging it carefully before withdrawing—the stubborn gate gradually began to yield.
"Ooh..."
Before I knew it, I was gripping the edge of the bed, my face so close to my stepmother's massive, childbearing hips that I could practically lick her.
The intense, briny scent of semen and the sweet, brain-melting aroma of female arousal simultaneously invaded my nostrils, sending a prickling heat through my lower body.
When my index finger sank in deep enough to reach the first knuckle—
"Ugh♡ Kuuuu♡♡"
A groan that bordered on agony escaped her lips, and her buttocks quivered with a brrun♡.
From there, it happened in a flash.
Squelch♡
"Aah♡ Nnnnnn♡♡♡"
Right before my eyes, Minori-san's index finger slid all the way into her anus with a nuru♡ sound, and she let out the same shrill cry she had when I first entered her vagina.
