Oh, he's watching me... So close... My own son... Watching me... probe my asshole...
Minori was a born masochist, the kind of woman who got wetter the more embarrassed she felt.
As she felt the rough breathing of her stepson against her buttocks, she gently stimulated the softened mucous membrane inside her anus with her index finger, making soft guchi, guchi sounds.
At first, she had to manually stretch the hole. Just like in sex, the key was to properly acclimate the body to the foreign object. The anal area, not designed for sexual intercourse like the vagina, lacked the elasticity and contractility of the latter, making proper preparation crucial. And what was the purpose of this preparation? To ready her asshole for Yosuke's massive cock, of course.
While Yosuke was holed up in a hotel room with a female classmate, Minori indulged in plenty of solo anal play to "condition" her hole. So, in reality, she could probably swallow Yosuke's massive cock right now with just a little help from some lubricant. But since this was the momentous day she would lose her anal virginity, she wanted to be fucked raw with his rock-hard member until he was about to burst.
Even if Yosuke's penis were to tear her anus, she was confident she could love even that pain.
In any case, she wanted to drive her stepson's boundless sexual desire to its peak before letting him enter her.
Though Minori had experienced countless lewd acts, this would be her first time engaging in anal sex.
My anus, which had never been invaded by anything but my fingers and lifeless toys, longed to be filled by my beloved son's member. And of course, I wanted his hole to be flooded with ample proof of our love, making me writhe in ecstasy.
Slurp... Slurp...
The same wet sounds that came from my vagina now echoed from my anus.
It feels so good... My ass... It's become so sensitive... It's actually turning into a proper erogenous zone...♡♡
At first, it was just plain disgusting. It felt like raw, unflushed waste was pooling inside.
But through repeated trials, fueled by Minori's innate masochism and sensitivity, my anus gradually began to generate distinct sexual pleasure.
After learning that Yosuke-san was interested in anal sex, I practiced a lot!
Squelch... Squelch...
He wasn't just kneading inside me; he added strokes and twists, too.
The inner wall of the anus is separated from the vagina by a single, thin layer of tissue. By pressing and thrusting against this wall with the pad of a finger, it's possible to stimulate the g-spot from behind. The pleasure isn't as intense as direct contact, but the urgency of the sensation is strangely addictive for masochists like Minori. Craving that final, elusive climax just out of reach, her finger movements inevitably grow more frenzied. She becomes vulgar, unable to stop.
"Ah!♡ The anus!♡ It's making me feel it!♡♡ It feels... so good!♡♡"
She arches her back as high as possible, flaunting herself to Yosuke.
She had already confirmed that his penis was primed for battle.
But she wants to push him further, to stoke his desire even higher.
Her self-control is slipping. She wants him to force his dark, crimson cock into her anus like a rapist, to violate her.
"Only your fingers... I don't want just your fingers, Master! Please, Master! Let me use... let me use a toy!"
She deliberately let saliva drip from the tip of her tongue as she turned to plead with Yosuke.
Oh, Yosuke... your face looks so lewd! You're getting aroused just watching my ass!
She was overjoyed, shivering with happiness.
It was an overwhelming sense of bliss.
"Toy... ah, ah... where do you want me to... play with it?"
In response to her stepson's somewhat listless question, Minori answered, wriggling her hips in a figure-eight motion.
"My asshole! My ass pussy! Stick the anal pearls in there! I want to fuck myself!"
Her stepson had probably seen similar scenes in adult videos before.
Yosuke gulped audibly, perhaps anticipating the sight before him.
How cute! Minori thought.
To think the "Master" who had become so thoroughly accustomed to his sadistic ways would be so shaken.
Of course, being Yosuke, even though he was shaken, the meaty spear dangling between his legs remained as vigorous as ever.
This male possessed an insatiable curiosity for the unknown, fueled by relentless vitality.
Really... I just want Yosuke to use my anus already, though...
She circled her finger inside her anus, then slowly withdrew it, leaving a slick trail of lotion.
Then, spreading her cheeks with both hands, she exposed her gaping "second masochist hole" before her Master.
"Please, Master... In this hole... Insert the anal pearls...!"
Now, just looking at Yosuke's face made both of her holes ache uncontrollably.
Minori's ache tonight wasn't just about lust; it was tinged with jealousy toward younger women.
Her pussy must be tighter than mine, the married woman's...
She'd forgiven Yosuke's "infidelity" for a calculated reason.
By deliberately letting him take a younger, more attractive woman, then showing him the deeper pleasures of a mature woman, she aimed to trap him in the belief that she was the only one who could truly satisfy him.
Could a high school girl even do something like this?
"Look, look! Can you see it? My anus is gaping open like my pussy, desperate for your cock! I want your cock so badly! I'm begging, I'm crying for it!"
Already, Minori possessed a bewitching aura. Her mature allure, honed by her late-thirties years, combined with the excessive pheromones released by chronic sexual frustration, drew the gazes of every man in her vicinity and left them aroused just by her presence.
Her voluptuous body, not an ounce of fat out of place, bulging with feminine flesh, writhed and danced seductively, performing what she called her "cock-begging ass-shaking dance." This display was so potent that it could make an inexperienced high school boy's penis spontaneously ejaculate, spurting semen with a plop plop.
Can Yosuke-san really take me seriously?
Aware of her unseen romantic rival, Minori presented her son with her crimson, lotion-coated "anal rose."
"Rape me! Please, Master! I secretly developed my asshole... Feel free to violate it with your toys however you like... please! ♡♡"
For a moment, Yosuke remained motionless.
Minori panted, Haa♡ Haa♡, her breath puffing pink clouds as she waited, her arousal leaking from her pussy.
Finally, her stepson's hand reached for the table.
He gripped the handle of the clear purple anal pearl.
"Aahh♡♡"
Her mouth, pussy, and even her asshole dripped uncontrollably.
The slick, dripping married woman trembled all over with anticipation. "Do it!♡ In my ass!♡ Stick it in my ass pussy, please♡♡" she begged.
"You really are insane, Minori-san," came the familiar, cold voice of her beloved "Master."
A soft, silicone-like sensation pressed against her buttocks.
"I'm sorry!♡ I'm sorry I'm such a pervert!♡ I'm just a stupid married woman who thinks about sex all the time!♡♡"
The tip of the anal pearl tickled Minori's anus.
The sensation alone sent shivers down her spine. Just thinking about how Yosuke would violate her anus made her uterus clench involuntarily, overflowing with thick, sticky arousal.
"You want me to defile this filthy hole where your shit comes out?"
"Yes, Master! I want you to fuck my shit hole... hard!" she panted.
Hic! Hic!
Her anus writhed as if answering Yosuke's words.
She couldn't take any more teasing.
"I want it! I want those anal pearls in my ass! Fuck me! Please, Master, fuck my ass pussy!"
"Alright, alright. As you wish, Minori..."
Splash!
"Ah... Oh... Oh...!" She gasped, her voice dripping with shameless pleasure.
Her chin tilted back, her hips trembling, the sensitive, lecherous married woman expressed her delight.
Oh... My ass... It's coming in... It's coming in... Deep inside...!
"See? How's this?"
Splash! Splash! Splash!
What?! All at once?!
"Ah?! Oh... Oh... Oh... Oh...!" She cried out, her voice breaking.
Yosuke didn't hesitate.
Just as Minori had hoped, he began pounding her anus with even greater ferocity than she'd anticipated.
The 12-inch-long anal pearl was thrust all the way in with a single, brutal motion, its base buried deep within the cheating wife's rectum.
Then, Yosuke smirked.
