Joo-ah, seemed tired and fell asleep without washing. I quickly wiped her body with a wet tissue and removed the soaked blanket. The blanket was so wet that I had to put it in the washing machine.
'Even with good soundproofing, she must have heard everything.'
It was embarrassing, but at that moment, I was so consumed by lust that I didn't think about my mother-in-law.
'But it was supposed to be soundproof.'
I didn't know. I didn't expect my mother-in-law to be aroused by our passionate sounds and pleasure herself.
Ahh, hah, ahng, ahng, yes, hah! This is it! Hah!
Bzzz- Bzzz-
When I put my ear to the door, I could hear the loud sound of a device running.
'Crazy world. Crazy world.'
Is this really reality? A son-in-law listening to his mother-in-law masturbating….
What would happen if I opened the door right now and fucked my mother-in-law?
'Father-in-law isn't home today.'
Dangerous.
Even in an adult novel, you don't just fuck someone else's wife. My mother-in-law has a husband who is very much alive.
Ahh, ahh, ahh, yes, more! Hah! More, harder!! Ahh!
My dick gets harder. Temptation pours out. It's not necessary to put my penis inside Joo-ah body to have sex. My dick, which has been refreshingly ejaculated, expresses dissatisfaction.
'Yes, your situation. I'm still hungry.'
Would you not eat such a ripe fruit? And you call yourself a man?! If you don't move now, I'll call you impotent!!
Ahh, dear! I'm dying! Hah hah!
Ahh… yes! Hah! More, deeper!! Not enough!
'Fuck, I think I'm going crazy.'
Maybe the sound of moaning turned her on. Since I was the cause, I couldn't blame her.
Should I? Shouldn't I? Should I? Shouldn't I? Should I? Shouldn't I? Should I? Shouldn't I? Should I? Shouldn't I? Should I? Shouldn't I? Should I? Shouldn't I?
Standing in front of the door, I was thinking like crazy. I was agonizing and agonizing again. I had to consider whether I could handle the aftermath if I did it. Naturally, the time for contemplation grew longer. I wanted to man up, open the door, spread my mother-in-law's legs, and stick my dick in, but this is not a novel, it's reality. Joo-ah is pregnant with my child, so she is a woman I will spend my life with. How could I easily touch her mother? While I was struggling between impulse and reason, the door suddenly opened.
"?!"
"Huh!"
It was my mother-in-law. My mother-in-law, who has bigger breasts than Joo-ah. And she was wearing a white undershirt. Not to mention the cleavage, her nipples were clearly visible as she wasn't wearing a bra. Moreover, her nipples were erect and prominent from the sweat of her self-pleasure. A sexy smell filled the air, her cheeks were flushed, and below….
'Oh, fuck. Crazy.'
Her thighs were wet with love juice, and her black pubic hair was clearly visible. My mother-in-law didn't seem to realize she wasn't wearing anything below and didn't try to cover herself. The problem was that I was in a similar state. I was holding a wet blanket that smelled of night flowers, and my bulging erection was visible through my pants. Our eyes quickly scanned each other's exposed bodies.
Gulp-!
"...."
"...."
There was a moment of silence. My mother-in-law's eyes flickered wildly as she realized the situation and stammered.
"C-C-C-Could it be…?"
"I-I-I need to do some l-l-laundry… uh… where is the washing machine?"
I thought it would be best to pretend I didn't hear anything. So, I tried to calmly explain that I came to ask where the washing machine was, but damn it! The words didn't come out smoothly as I thought. I must have been very flustered. In the end, my mother-in-law was sure that I had heard her masturbating. Her gaze was fixed on my lower body.
"T-That is…."
Under her gaze, my dick got even harder, like a cheerleader being cheered on.
-Bulge
Seeing it grow even more clearly, my mother-in-law shivered.
"…Ahem, didn't you just finish?"
"…Yes."
Until I heard your masturbation sounds, it was calm. My dick was satisfied. This is not my fault. Where in the world is there a mother-in-law who masturbates to the sound of her daughter and son-in-law having sex? I spoke up before my mother-in-law could look at me with disapproval.
"What man could stay calm hearing you moan like that?"
"You mean you got excited hearing a woman like me moan? It felt like it lasted almost an hour."
"It was almost an hour. I came four times."
"F-Four times?"
-Gulp
The sound of my mother-in-law swallowing was unusually loud.
"Wasn't the sex with Joo-ah satisfying?"
"Of course not. Until just now, I was completely dead. This is 100% because of you."
I blamed the entire situation on her. Surprisingly, she nodded in agreement.
"Y-Yes. It's because of me. Because I was being shameless. So, I'm sorr… Eek!?"
Realizing belatedly that she wasn't wearing anything below, my mother-in-law screamed. With nothing to cover her lower body, she used her hand to cover her black pubic hair. The sight of her trying to cover her exposed nipples while hiding her lower body was shocking and arousing. I couldn't look away.
"Y-You're staring too much."
"I thought looking was okay. Is it not?"
I thought it was amazing that I hadn't pounced on her yet. She seemed burdened by my gaze and slowly turned her lower body away. But that wasn't a good move. Her plump, juicy butt was right in front of me.
Thud-!
I dropped the blanket. I wrapped my arm around her waist as she tried to go back into the room.
"Eek!"
She was a bit plumper than Joo-ah. But this wasn't fat; it was voluptuousness. Her breasts were overwhelming, and that voluptuousness was evident in her butt as well.
Squeeze, squeeze, squeeze-
"Eh! Eh!"
I vigorously squeezed her butt and rubbed my hot, throbbing dick against her.
"Eek! No!"
"You say no, but your legs are spreading wider."
"H-How can you do this to Joo-ah!! A-And I have a husband. I don't want to show him a disappointing side. You'll meet him later, so how will you face him? So let's stop here. Okay? We can still pretend this didn't happen."
I chuckled at her words. She was saying one thing, but her body was doing another.
Rub, rub, rub-
"Ah… ah…!"
Her butt rubbed against my lower body. Juice from her pussy was smeared on my pants. The decision that had been agonizing became easy. I inserted my finger into her pussy and pulled it out.
"Ah!"
Drip!
"You're dripping with love juice, so your words have no credibility, Mother-in-law. Just inserting and pulling out my finger once made it all wet."
"Eek!"
I still called her "Mother-in-law" out of respect, but…
Right now, I just wanted to call her that. And at my call, a sense of taboo aroused her, and love juice gushed from her pussy.
Zip-
"You're driving me crazy. If you wanted to seduce me, you've succeeded."
I unzipped my pants, took out my dick, and rubbed it against her pussy. My dick, which had been covered in my sister's saliva and love juice, was now covered in my mother-in-law's love juice. My dick quickly found her pussy hole. I teased her by almost putting it in and then pulling back, then just inserting the tip.
Thrust!
"Eek! No! Dear!! Ah!"
"You haven't had sex with Father-in-law in a long time, right? Your moans. You kept saying it wasn't enough. More, harder!"
"Stop!!"
"I'll do it for you. Think of it as trying a new dildo to make you feel better."
Since she seemed to like it rough, there was no need to hold back. I thrust my dick into her pussy, which was already loose from the device.
Thrust!!
"Ah, ah, eek, ah, ah, yes!!"
Thrust! Thrust! Thrust! Thrust! Thrust! Thrust!
Overwhelming pleasure. There was no need to take it slow and enjoy foreplay like with my sister. I swung my dick for fast and intense pleasure.
"Ahh, ah, yes! Ah! Unbelievable!! Eek! Ah! Hard!Eek! No! I can feel it!!"
Slap, slap, slap, slap
Squish, squish, squish, squish-
"Shh! Mother, you'll wake up Joo-ah. She just fell asleep, and if you don't want to wake her up, you should be quieter."
"Mmph! Mmph"
Even in her state of ecstasy, she listened to me and covered her mouth with her hand.
Slap, slap, slap, slap
"Whew! Whew! I can't believe it. Your pussy is amazing! Ah, it feels so good. Different from Joo-ah."
"Mm… mm… mm… mm…!"
"You take it all in, Mother. Joo-ah's pussy isn't as deep, so my dick doesn't go all the way in."
"Eek!!"
I thrust my dick deep inside her and then pulled it out completely, swinging my hips forcefully to penetrate her deeply. My mother-in-law, who was holding onto the doorknob, finally let go. Since I was holding her butt tightly, she had to fold like a folder. I could have been more considerate, but I remembered her moans while she was masturbating.
'More, not enough, harder!'
I couldn't have her saying it wasn't enough after sex with me. I grabbed her thighs and lifted her up. The so-called 'standing doggy style.' She was a bit heavier than my sister, but I could handle it.
'I need to level up my strength.'
To enjoy sex in my desired position for a long time, I needed more strength. Of course, I wasn't lacking in strength now. I vigorously shook her body up and down.
"Ah! Ah! Ah! Ah! Ah!!"
Squish, squish, squish, squish-
Her breathing became incredibly rough. Let's go to the bed. With my dick still inside her pussy, I moved to the bed. I closed the door with my foot in case Joo-ah woke up.
