The Concentrated Seed of a Mother
"Yes, ahh♡ Hnggg♡ Ah!!♡"
Squish. Squish.
Perhaps it was because this was my first time having sex with Mom in a while. Or perhaps, because she was my mother, she simply knew exactly how to make me feel the best. Even though she was just rubbing her penis against my cunt, it was so incredibly stimulating that... a moan like a female in heat spilled from my lips on its own.
"Mmm...♡ My dear Jian, are you dying to be impaled by Mom's penis? Your cunt is gripping the shaft so tightly and refusing to let go...♡"
If someone were to ask me who I had the best sex with since I transmigrated into this body, I could say "Mom" without a moment's hesitation. Of course, my first time with Gain-noona was intense, but even a month later, every moment of the sex I had with Mom remained vivid in my memory, not a single detail blurred.
The sensation of my womb being pierced over and over. The pleasure that raged through my brain for over thirty hours. The way Mom moved her hips so roughly, contrasting with her gentle smile. That sex was so good that words couldn't even begin to describe it... I even forgot I was originally a man, lost in the memory of being with her.
"Y-yes...♡ I missed you so much, Mom... hng♡ My cunt felt so empty...♡"
"Oh, my. My pretty daughter. Did your cunt feel empty because Mom didn't have her penis inside?"
"Yes...♡ My womb felt empty because I wanted Mom's semen...♡"
Perhaps my female-ness had increased significantly. Even though the words that spilled from my mouth were vulgar, there wasn't a single lie in what I just said. It was true that I missed Mom terribly, and the house felt so empty without her.
"Then Mom will have to fill your cunt so it doesn't feel empty anymore, won't she?♡"
"Yes♡ Fill my cunt, fill it up, Mom...♡"
"Alright. Then...♡"
Mom grabbed my waist as I lay on the mattress and immediately slammed her penis vertically into my womb.
SQUELCH!!
"Hngggghhh——!!♡♡"
As soon as Mom thrust in, my back arched on its own. Unlike the others, Mom's glans pressed forcefully against my womb. Under that pressure, I couldn't help but spray lubricant and reach a climax.
"Oh, ahh♡ Ohhh...♡"
"Huu...♡ My daughter's cunt, it's been so long, but it's still such a masterpiece♡ Tightening around Mom's penis so nicely...♡"

Along with the message, pink hearts floated in Mom's eyes.
As the affection rating has reached the limit, heroine 'Im Yerin' is now in heat for you.
"I just can't help but dote on such a lovely daughter's cunt...♡"
Mom slowly pulled her penis out of my cunt, leaving only the glans inside, before thrusting it back in all at once.

THWACK!!
"Eek!?♡"
Squelch—thwack! Squelch—thwack!!
The repetition of slow withdrawals followed by deep, root-level thrusts. Every time she scraped the vaginal walls and slammed her glans into my womb... the pleasure was more than a female could bear, forcing me to climax with every single thrust.
"Hnggg!!♡ M-Mom♡ Mmm, ahh!!♡ The penis, hick♡ It's so good♡"
"My Jian, do you like Mom's penis that much?"
"Yes♡ Hnggg♡ Having my empty cunt filled up by Mom's penis is just, ahh♡ It's so good♡"
Even though intense waves of pleasure were crashing over me, making my tongue go limp, I hugged her tightly with my arms because I didn't want to be apart from her. Mom's embrace was so warm, I never wanted to leave. She looked at me, rubbing my head against her, with loving eyes, then gripped my waist tightly and spoke.
"Jian...♡ If you keep tempting me like that, Mom might just lose control for real...♡"
Heroine 'Im Yerin' is currently suffering from sexual frustration due to not being able to masturbate for a month.
Heroine 'Im Yerin' is even more in heat for you.
Her penis was writhing inside me, as if it wanted to tear my cunt apart right now. Perhaps it was because, despite her frustration from being away on business, she chose to come to me instead of another woman. A surge of joy filled me, and I wrapped my legs around her waist, pulling her even closer.
"Show me... for real...♡ Since you've been away on business... you couldn't do it much, right?♡"
"Oh my...♡"
"Please ejaculate as much as you've built up inside my cunt♡"

With the message appearing, Mom took a deep breath and said, "My daughter...♡ Mom loves you so, so much♡" With those words, she began to thrust like a madwoman.

Slap-slap-slap-slap-slap!!!
"Hnggg!♡ Ohhh!♡ Oh, hnggg!!♡ Hnggg♡ Hick♡ Ahhh!!♡"
As I received Mom's hip thrusts, ruthlessly assaulting my womb with her glans, I realized something. Even during that thirty-hour non-stop session before, Mom had been holding back. If she had really wanted to, she could have truly killed me with pleasure.
"Hngggghhh!!♡"
Splurt! Spluuuurt!!
Unable to withstand the tidal wave of pleasure, my body repeatedly poured lubricant out. Perhaps even the boss hadn't expected Mom to be capable of such sex; the expression on the boss's face as they watched us was one of pure shock.
"Haaah♡ M-Mom♡ Ah!!♡ Hnggg♡ My womb, it feels like it's going to be crushed, ohhh!!♡ Save me, save meee♡"
At this rate, I really felt like I would break. My body couldn't possibly endure it, but even as I begged her to save me, Mom only gave me a soft smile and didn't stop her thrusting.

"My daughter♡ You have to take all of Mom's semen inside...♡ Take it all, and later... you'll have to get pregnant with Mom's baby, too♡"
Vulgar words that were hard to imagine coming from my own mother. But perhaps because I was already deeply infatuated with her, the words didn't sound bad at all.
Your female-ness increases due to the womb conquest of heroine 'Im Yerin'.
This heroine is your family.
Your female-ness increases even more significantly.
Even though I was fully aware that I used to be a man, "Haaah♡ Mom, Mom♡ Hnggg!!♡"
"Mmm, mmm♡ My daughter♡ Mom is right here...♡"
As I kept calling out to her, Mom hugged me tenderly. And then, a kiss followed. Mom skillfully sucked and licked my lower lip, then forced her tongue between my lips, gently licking every corner of my mouth.
"Hng, slurp♡ Smack...♡ Chuu, haaah♡"
The intense kiss only ended when Mom pulled her lips away just before I suffocated.
"Huu...♡ My daughter is just such a lovely female♡"
"Haaah, haaah♡"
"I can't help it. I'll have to turn you into an onahole that can't be satisfied by anyone but Mom♡"
With increasingly rough thrusts, her penis pulsed deeply inside my cunt. It seemed Mom wanted to ejaculate inside me. "Mom, ahh♡ Hnggg!♡ Inside, ejaculate inside♡ Inside my womb, inside my baby-room, fill it all up♡"
I gripped my cunt tightly, tempting her because I desperately wanted to receive Mom's semen into my womb. Succumbing to my temptation, Mom thrust in until the very root.
"Alright. I'll fill your pretty daughter's womb with the semen Mom has been concentrating for a month without letting out♡"
Almost as soon as she finished speaking,

Spluuuurt!! Spluuuurt! Spluuuurt! Spluuuurt!! Spluuuurt!!
Like water pouring from a waterfall, semen began to erupt from Mom's glans.
"Eek!!♡ M-Mom♡ Ah!♡ Hnggg♡ Semen, it's filling me up♡"
"Mmm, that's right♡ Mom is filling you up inside, my Jian...♡ Take all of Mom's semen♡"
Hearing Mom's words, I tried my best to receive her semen into my womb, but... Splurt, splurt! Spluuuurt!! Perhaps because she hadn't ejaculated for a month, my womb couldn't handle the sheer volume of her ejaculation.
"Haaah♡ Mom, wait...♡ It's too, too much, hnggg!!♡"

Spluuuurt——!!
"Haaaaah!!♡"
I was clearly just being ejaculated into, but the unstoppable waves of pleasure forced me to climax over and over again. Splurt, splurt! Spluuuurt!! It wasn't enough that my belly was bloated like a pregnant woman's; Mom's ejaculation only stopped after the overflowing semen had coated half the mattress. Yet, even after pulling out, Mom's penis remained firmly erect, as if she still wasn't satisfied.
"Mmm...♡ I want to do more with my Jian...♡"
Mom said, her penis twitching as if she were still unsatisfied. But as if to tell her not to even think about it, the boss pushed Mom aside and placed their penis on my lower belly, looking somewhat nervous.
"Hey now. You have to follow the order. What we're doing right now is a competition."
"Hmph."
"I'll take good care of your well-raised daughter, so don't worry too much."
The boss winked at Mom and then, without hesitation, thrust their penis into my cunt, which was still overflowing with semen.
THUUUUST——!!
"Eek!!!♡"
