My... no, my mother-in-law's massive ass was right in front of me, captivating my gaze completely.
"Here you go~ This is Mommy's butt that my son loves the most ♥"
Shake, shake, shake, shake.
Gulp...
I'd grown used to her ass by now, but familiarity didn't make it any easier to resist. It wasn't that weak.
I knew she was deliberately tempting me into some kind of pseudo-incestuous sex, yet my body and mind were still ensnared by that ass.
"Thinking of her as Mom makes it even more... gulp..."
On top of that, even though it was just a term of address, the way she called me her son while seducing me sent my heart racing wildly.
Shake, shake, shake, shake.
Unlike ordinary asses, hers was thick yet firm, an irresistible allure. My cock throbbed rigidly, eager to plunge inside.
With every sway, her huge ass jiggled, and before I knew it, my hand reached out.
Squeeze.
"Haa ♥ You don't have to grip it so hard—Mommy's butt isn't going anywhere ♥"
'I grabbed it without thinking.'
Her big, delectable ass was so large that my hand sank into it slightly, and so soft I couldn't pull away.
Rub, rub, rub, rub.
"Haa ♥ Haah ♥ If you love Mommy's butt that much, you can touch it all you want... because it's yours ♥"
"M-Mom..."
"Hahaha..."
A lewd mother who'd handed ownership of her ass over to her son.
The way she shook her naked ass to seduce him, licking her lips as she eyed his cock—it was utterly unbearable.
"Here ♥"
Press.
"Haha..."
"I'll give you a buttjob, son ♥"
She pressed her massive ass cheeks against my cock and wiggled like she was really jerking me off.
Slide, slide, slide, slide.
"Use Mommy's butt as your onahole, son ♥"
She tempted me with vulgar words, as if soothing a little child.
The skillful way she rubbed her ass against my cock made me buck my hips unconsciously.
"Haaang ♥... Haah ♥ You can use it whenever you want ♥ Mommy's butt is your personal fuckhole now ♥"
I gripped her ass hard, fingers digging in, and ground my cock against it. My lewd mother-in-law—no, my mom—offered herself willingly.
The way she sacrificed everything, even crossing forbidden lines to become her son's possession, only fueled my sadistic urges further.
Squeeze.
"Hahahaha..."
I grabbed her ass and spread it wide, exposing the lewd hole hidden within.
I couldn't tear my eyes away from that hole, which stirred a male's primal instincts, right alongside her pussy.
I rubbed my cock against it.
"Haaahhh ♥ N-no, not yet ♥ You can't jerk off with Mommy's ass ♥♥"
'If I put it in here... gulp!'
I debated shoving it into her ass, which twitched as if begging to be filled...
"Son, wait just a little longer... I'll let you put it in there later... I'll give you everything later... okay?"
"Haa... Okay, Mom."
"Haha..."
I decided to hold back for now, but my cock pulsed like it couldn't wait any longer.
"Is your cock mad, son? ♥ Is it angry because Mommy wouldn't let it eat her ass? ♥"
Press, press, press, press.
She wiggled and rubbed her ass against my cock as if trying to appease it.
It was like she was calming my dick, but it only swelled bigger, as if even angrier.
"I'm sorry for not letting your cock devour it ♥... Punish Mommy however you want for not giving it to you right away ♥"
Shake, shake, shake, shake.
She begged for punishment while shaking her ass wildly.
Her expression held a deep smile, even as she asked to be punished, but I raised my hand high to vent my boiling desires and frustrations.
Slap!
"Hoooo..."
I only hit her once, but a bright red handprint clearly marked her ass.
"You said you'd give me your ass!"
Slap!
"Hoooo..."
"Why won't you let me put it in?"
Slap!
"Oooooooh ♥"
She squealed like a pig, drenched in pleasure from the spanking.
I'd only smacked her a few times, but her ass quickly turned red, branded with my handprints.
Seeing those clear marks, as if declaring it mine, eased my frustration a bit.
"I'm sorry... haha ♥... Mommy's backdoor needs a little prep ♥... Please wait just a bit longer ♥"
She was being punished with ass slaps for not giving her son her hole right away, yet she apologized even more and shook her ass teasingly.
"Instead ♥..."
Squish.
She grabbed her own ass and spread it wide, revealing her pussy dripping with lewd fluids.
"Please make do with Mommy's pussy for now, son ♥"
Since she couldn't give me her ass yet, she offered her pussy instead.
Squish.
"Haaang ♥ Come in, son's cock ♥"
She was fully immersed in her role as mother, unhesitatingly calling me her son.
"Mom!!"
Squish.
"Haaahhh ♥ Devour me however you want ♥ Pound Mommy's pussy as much as you like ♥"
Squelch, squelch, squelch, squelch, squelch.
I lost myself completely in this depraved situation, calling her "Mom" as I thrust my cock deep into her pussy.
"Aang ♥ Aang ♥ It's so touching—son's cock is hitting Mommy's womb ♥♥"
Squelch, squelch, squelch, squelch, squelch.
She moaned lewdly, lost in the sensation of her son's cock reaching her womb, smiling wickedly as she was ravaged.
"Mom..."
"Haa ♥ Mwah ♥ Haa ♥ Mmm ♥ Mommy's mouth is yours too ♥"
I couldn't hold back—I yanked her arm hard, grabbed her breasts, and kissed her.
"Haa ♥ He ♥ Mwah ♥ He ♥ Mmm ♥"
She continued the lewd kiss, tangling her tongue with mine.
"Her mouth and breasts are so soft."
Her body was so arousing it wasn't an exaggeration to say it existed solely to seduce and excite men.
I squeezed her massive breasts so hard they distorted, and thrust my cock so forcefully it battered her womb, but as a masochistic woman made for easy use by men, she reveled in it all.
Squelch, squelch, squelch, squelch, squelch, squelch, squelch.
"Hehehe ♥ Son's cock is getting bigger ♥ Cum inside ♥... Fill Mommy's womb with your thick semen ♥"
Mom!
Spurt, spurt, spurt, spurt, spurt.
I couldn't hold back against her overwhelming lewdness and depraved whispers—I came hard.
"Hahahahahaha..."
Gush.
She'd held out until now but finally climaxed, squirting her pussy juices everywhere.
"Hahahahahahahahahaha..."
She looked thrilled at her pussy overflowing with my semen.
"Haha... Mom... Mother-in-law."
"Hehe... It's fine... If you want to call me Mom, you can anytime... I'll be your mommy."
She gave me a kind, warm smile, and I couldn't help but smile back.
"Or should I just register you as my son on the family registry instead of marrying you to Yeonji? ♥"
"M-Mother-in-law, that's..."
"Hehehe ♥ Just kidding... But if that happened, I'd have done it with my real son... and Yeonji would have done it with her brother ♥"
'If that really happened, it wouldn't end as a joke... I don't know if she did this for me or because she wanted it...'
I wasn't sure if she'd roleplayed as mother-son just to create a depraved atmosphere, or to ease my longing for a mother.
'Or maybe both...'
"Hahaha... I only did it once, but my back hurts... I guess it's because you were so rough yesterday ♥"
"Oh... um... sorry about that."
"No, it's fine... If anything, I was so happy to be ravaged by my 'Master' instead of my 'son-in-law' right on top of my daughter ♥"
She smiled contentedly at the depraved sex we'd had yesterday.
"I'm looking forward to when Yeonji wakes up too... ♥"
"..."
I'd only been able to do it because Yeonji had passed out from the pleasure—it would've been impossible if she'd been conscious.
'But maybe...'
Yeonji was her daughter, after all, inheriting much of her looks, personality, and tastes.
Because of that, she often showed her own M tendencies, even if not as extreme as her mother's. So maybe someday, she'd become a woman just like her...
'It could be... Yeonji...'
I couldn't be certain, but I couldn't say for sure it wouldn't happen.
"Oh dear ♥... Were you imagining doing it with Yeonji and me together?"
"..."
"Hehe ♥... You must be tired, so this time I'll serve you from on top... Master ♥"
She hit the nail on the head, as if reading my mind.
Without pressing further, she laid me back and straddled me, spreading her legs to show her pussy with my cock inside.
"Then let me serve you, Master ♥"
Squelch, squelch, squelch, squelch.
"Haa ♥ Haang ♥ Master's cock is amazing ♥ It feels so good—still rock hard even after dumping so much thick cum ♥"
She'd transformed into a female beast, no longer mother or mother-in-law, serving me with a lewd smile.
Her massive tits bounced, delighting my eyes.
"I like it... Jeongyeon."
"Haha..."
I casually called her by name and squeezed her ass hard, and she sped up her hips, saying she liked it even more.
I received her lewd service and finally felt satisfied after two more rounds.
