Mutual Masturbation with Mom
“What did you say?”
Yui asks again even though she clearly heard me.
“If you show me you masturbating right in front of my eyes just one more time, I think I’ll be able to forget it. Then I’ll probably be able to focus on studying too…”
The moment I even brought up studying, her pupils trembled.
But she still doesn’t answer.
“…”
“Never mind, Mom. I must have gone crazy. Just pretend you didn’t hear that.”
As I stood up and tried to head to the second floor, her urgent voice stopped me.
“T-then… it really only needs to be once, right?”
A smirk tugged at my lips.
“Yes. Just once, I swear. Otherwise I keep thinking about yesterday and it keeps flashing in my head…”
“Alright. I understand. Come this way.”
She led me into an empty room on the first floor.
It was the guest room she usually prepared for visitors.
No one ever used it, but since Yui tidied the bedding every day, it was still spotless.
Click.
The moment I stepped inside, she firmly locked the door.
In case anyone came home.
To avoid repeating the same mistake.
I sat down on the desk chair.
Yui hesitated for a moment, then, as if she’d made up her mind, began taking off her clothes.
Slide.
Her slender neckline,
her full, heavy breasts,
the bra squeezing them tightly so they wouldn’t sag,
her narrow waist below that,
and the slight pouch of her belly.
After giving birth to three children, it was hard to believe that stomach belonged to a mother of three. Beneath it lay the black panties covering her most important place.
Inside those panties was a cave that had only ever been allowed to her husband.
“You’re beautiful, Mom…”
When I stared at her openly, her face flushed and she turned her head away.
“Don’t… stare so hard.”
“It’s because you’re too beautiful.”
It must have been a whirlwind of emotions for her.
She had probably wanted to hear those words from her husband, but he was away on a business trip.
The masturbation she did every day to soothe her loneliness.
Now her adopted son had caught her doing it, and those same lips were telling her she was beautiful…
She sat down on the edge of the bed, leaning her back against it, and looked at me for a moment.
I quietly stared back at her.
A long standoff.
In the end, she was the first to speak.
“If you really watch me masturbate… you’ll be able to forget?”
“Yes. I swear. I’ll forget what happened yesterday.”
“Okay. I understand.”
Thud.
Sliiide.
Jiggle.
She removed her last piece of underwear.
As the bra came off, her large breasts, no longer fighting gravity, swayed heavily.
And then the panties.
She took them off slowly, clearly reluctant to expose her most private area, but it was pointless in the end.
Soon she would spread her own legs and slide her fingers inside.
All I had to do was wait patiently.
“S-so… I’ll start?”
“Yes.”
I stared at her intently.
She stopped avoiding my gaze and began kneading her breasts the way she always did.
Her routine never changed.
It always started with touching her breasts.
“Ah♡ Hngh, mmmph.”
The moment she realized I was right in front of her, she tried to hold back her moans.
Her body was so sensitive that just grabbing her breast once was enough to make her feel it intensely.
A woman like her had been sleeping alone for a long time because of her husband’s business trips. The only way to relieve that was through masturbation.
The fingers that had been massaging her breasts slowly moved toward her nipples.
At first, she circled her index finger around the nipple.
Then she glanced at me, checking my reaction.
Gulp.
When I swallowed hard while watching, she moved her fingers again.
She pinched the nipple between the pad of her thumb and the side of her index finger and gave it a slight twist. Immediately, another moan burst out.
“Hah! Haaang♡”
Then she slowly slid one hand down to her pussy.
Squelch, squelch.
She scooped up the love juices that had already begun flowing from caressing her breasts and spread them over her outer lips, rubbing in slow circles.
Her entire pussy glistened wetly from the slick fluid.
I wanted to rush over and lick it right then, but I held back.
It wasn’t time yet.
I had to make her beg for it herself.
“Haaang♡”
After coating her outer lips completely, she gently spread the inner lips and applied the juices there as well.
Squelch, squish.
“Haaahng♡ Haaauu…”
Then her index finger disappeared inside her pussy.
Squelch, squish, squelch.
“Aaaahng♡”
Suddenly her finger movements sped up.
She tugged hard on her own nipple while thrusting the finger in and out of her pussy repeatedly.
But it still wasn’t enough. Eventually she added her middle finger too.
Squelch, squelch.
Drip.
Every time her two fingers plunged in and out, her lewd cries and heavy panting filled the entire room.
Slide.
I stood up from the chair and took off my pants.
My cock was already fully erect.
It throbbed, the tip glistening with clear precum.
I wrapped one hand around it and began stroking up and down.
Squelch, squelch.
The moment Yui saw my cock, her movements froze.
That shocked expression.
She wasn’t surprised that I was masturbating. She was shocked by how enormous my cock was.
It was the same reaction she’d had when she saw it in the bathroom yesterday.
At first she must have been afraid I would approach her.
But I simply stayed in my seat, watching her while stroking my cock.
Soon she too returned her focus to her own masturbation.
Squelch, squelch.
Squelch, squelch.
“Haaahng♡ Haaang.”
“Ugh! Hngh!”
A man and a woman, watching each other masturbate and doing the same.
The room was filled with hot, heavy air, our moans, and the obscene wet sounds of our bodies.
“Haaang♡ Feels so good… mmmph!”
Without realizing it, the word “good” slipped from her lips while she was masturbating.
She quickly shut her mouth, but soon surrendered to the pleasure again.
Squelch, squish.
Now three fingers were plunging in and out of her pussy.
Normally two would have been enough, but not today.
The thrill of showing her masturbation to someone else.
And on top of that, seeing a cock as thick as her own forearm for the first time.
As a woman—as a female in heat—only one thought spun through her mind.
I want a male’s cock.
Yet she still clung to the last thread of reason.
Squelch, squelch.
Squelch, squelch.
Our hand movements grew faster and faster.
Both of us were racing toward the peak of pleasure.
We both knew it.
Even though we were apart, we could tell.
That the other person was about to cum.
And it didn’t take long for that moment to arrive.
“Hah! Mom!! I-I’m gonna cum!”
“Haaang♡ Haaaaang♡”
Spurt, spurt! Spluuuurt!
Pssshhhhhhh!
The semen that shot from my cock flew all the way to her crotch.
The love juices that gushed from her pussy slowly soaked the bedsheet.
She didn’t bother saying she was cumming.
She simply came at the same time as I did.
“Haa… haa… haa…”
“Hah…♡”
“Mom… thank you so much… I’ll never forget this for the rest of my life.”
“Mm…”
She quietly nodded, and I left the room first, leaving her there.
Click.
I closed the door.
Or rather, she would think I closed it.
I had made sure it sounded that way on purpose.
I watched her through the slight gap I had left open.
Unaware that I was still watching, she stared at the semen that had landed on her inner thighs.
Swish.
She scooped some up with her finger.
After staring at it for a moment, she brought it to her nose and sniffed.
“Sniff… sniff…”
Then she brought it to her mouth.
“Mmm…”
Slurp.
With an incredibly lewd expression, she sucked the semen off her own finger.
I stopped watching and went upstairs to my room.
The seed I had planted would soon sprout.
I’d have to water it well.
##
“Mom! I’m heading to cram school!”
“Okay, have a good time.”
The distance between us felt nothing like that of a mother and son who had just masturbated together a short while ago.
I acted like a cheerful son, and she played along.
Yet a strange tension still lingered between us.
…
“Yo~ Satoshi-kun. Long time no see.”
When I arrived at the cram school, Akira greeted me as usual.
This friend of mine really never changed.
“So, hast thou abandoned Dudaepan for some other game these days?”
“I don’t play games anymore. I’m going to study.”
“!!”
He looked at me with genuine shock.
Why?
Was it really that surprising?
“To hear such words from Satoshi-kun’s mouth… Hast some evil spirit possessed thee?”
I flinched.
It wasn’t an evil spirit, but it would be troublesome if he thought I was someone else.
“No, I just want to study properly, get into a good university, land a nice job, and make a lot of money.”
“Huu… If thou hast such grand aspirations, then I shall no longer try to tempt thee.”
“Tempt?”
“I was thinking we could go to the arcade together after class today.”
The arcade.
A place where data scraps like me gathered,
where people laughed and chatted while freely manipulating characters like me.
Just thinking about it sounded awful.
But… what was this feeling?
I kind of wanted to go.
I was curious.
I had the memories, but I was still curious.
“Maybe I’ll play just for today…”
“Oho! A wise decision indeed! I can hardly wait for class to end.”
Pfft.
When I laughed, Akira laughed too.
“Satoshi♡”
Nanami, who had now become my girlfriend, ran over and linked her arm with mine.
“Hi, Akira.”
“O-oh! Greetings, Nanami-chan.”
Thanks to my command not to act rudely toward others, she had transformed overnight from a delinquent into a good girl.
The two other delinquents she used to hang out with now looked confused and no longer approached her.
Squish.
Her soft breasts pressed against my arm.
She seemed a little obsessed with me.
I figured it was a side effect of using Hypnosis as a bug, so I decided to avoid overusing the bug from now on.
“What were you guys talking about?”
“Oh, Akira suggested we go to the arcade after class.”
“I want to go too!”
“Huh?”
“Why? You said you’d take responsibility, right? My puss—mmph! Mmph!”
When I quickly covered her mouth, Akira tilted his head.
“Puss? What were you saying?”
“Ah, it’s nothing. We have a little secret between us. Right, Nanami?”
At the word “secret,” she looked pleased and nodded.
Only then did I remove my hand.
Whew. The future looked worrying.
