The Serpent's Whisper
Letting out a heavy sigh right in front of your partner after sex was an act completely devoid of manners. But this was a special situation. Having failed to uphold basic human decency and ended up sleeping with his girlfriend’s mother, it would have been stranger if he hadn’t sighed. With a gloomy expression, I lowered my head slightly and dragged my palm down my face.
If the real me had been faced with this situation, I would have already decided that regretting what had happened was pointless and moved to actively handle the fallout. But the “good son-in-law Kim Minjun” I was currently playing was different. Because his nature was so kind, he was extremely vulnerable to the backlash that came after doing something bad.
“Haa……”
I let out another deep sigh with my head still bowed. I could feel Seol-young’s gaze fixed on me. Swish—. While quietly watching me suffer, Seol-young spread her arms wide, pulled me into an embrace, and gently patted my back.
“Minjun-ah. Don’t torment yourself too much. It’s all Auntie’s fault. Everything is Auntie’s fault.”
Though she was verbally taking all the blame, Seol-young probably knew deep down that I wasn’t the kind of person who would find comfort in those words. The “good son-in-law Kim Minjun” didn’t have the kind of excellent character that would shift all the blame for this mess onto Seol-young. Instead, seeing an angel like Seol-young trying to comfort me even in this situation by shouldering everything herself only made me feel deeper self-loathing.
“…No. Mother. I did something terrible to you… I’m truly sorry.”
“It wasn’t terrible. I… was the happiest I’ve ever been in the world. Because Minjun comforted Auntie, it feels like I can keep living. All that crushing depression has completely disappeared. You didn’t do anything terrible—you saved Auntie. Do you understand?”
“Ah, Mother…”
“Thank you for saving me, Minjun-ah.”
After finishing her words, she slowly pulled away from me. Then she took my hand and helped me to my feet.
“Come with me. Let’s go wash up.”
“Uh, Mother…”
She looked at me and smiled brightly. I instantly felt my cheeks flush and awkwardly took Seol-young’s hand as we walked. Once inside the bathroom attached to the master bedroom, Seol-young sat me down and turned on the shower, checking the water temperature. It was obvious she intended to wash me herself.
‘Service is pretty good.’
Since I originally liked it when women washed me, I was cheering internally, but I put on a flustered act and whined a little.
“I-I can wash myself.”
“Auntie wants to wash you. You got dirty because of Auntie, so Auntie will clean you up.”
“Dirty… It’s not like that…”
I dragged out my words to show embarrassment and awkwardness. Being washed by my future mother-in-law was a situation that would make anyone flustered if they thought about it again. Of course, I was enjoying it on the inside.
Whoosh—. Seol-young held the showerhead and soaked my body with lukewarm water. While I sat there awkwardly getting wet, she began wiping my body with a towel lathered in body wash. Swish—. Swish—. The steam in the bathroom, the sound of the towel gently scrubbing my skin, and the occasional brush of Seol-young’s touch—all of it combined sent my arousal skyrocketing. The whole scene felt exactly like a typical Japanese AV bath scene. I used to complain that they always did the same thing whenever I watched them, but now that I was experiencing it firsthand, I could understand why Japanese guys were so obsessed with bath scenes. It felt incredible.
While she was thoroughly cleaning every corner of my body, Seol-young’s hands gradually moved toward my crotch. The sensation of her gently caressing my intimate area made me unconsciously hunch my waist and let out a feminine moan.
“Hng…! Th-there, I’ll do it myself.”
“Why? Are you embarrassed even though it went in and out of Auntie’s pussy?”
“M-Mother…!”
“Hoho. Look how big Minjun’s cock got. How can something this magnificent even exist?”
“Th-that’s…”
“Just stay still, Minjun. Auntie will clean your cock for you.”
Seol-young said that, draped the rough-textured shower towel over my cock, grabbed it with both hands, and started shaking it up and down. Swish—. Swish—.
“Kgh…!”
“It’s twitching again… So one time really isn’t enough for you?”
“No… No, it’s not like that. Hng…!”
“It’s okay. Auntie can make you cum as many times as you want. Auntie will help until Minjun’s cock feels comfortable again.”
“Ah… M-Mother…! Aah…!”
Swish—. Swish—. Swish—. Swish—. Still kneeling, Seol-young shook my cock diligently, her ample breasts swaying heavily. Because she was gripping it tightly with both hands and using the rough shower towel, the stimulation was incredibly intense. Especially when the towel rubbed over the glans, goosebumps ran across my entire body and I trembled uncontrollably.
“S-stop! Mother…!”
“No, I’m not stopping. Anyway, this is something only the two of us know. And since it happened because of me, you don’t need to feel any guilt at all, Minjun.”
“No…! Mother, what are you saying…! Ha…!”
“It’s fine even if you live with Yeonju. Just stop by our house sometimes and comfort Auntie. Soothe me. If it’s not Minjun, I don’t know what I’ll do from loneliness…”
“That kind of… Please stop saying things like that…! Hng!!”
“Just the two of us. Okay? If we keep it as our secret, it’ll be fine. Nothing will happen. Yeonju won’t know anything. Minjun-ah. Minjun-ah.”
She was like the serpent in Eden offering the forbidden fruit. Seol-young was exactly that serpent. The sight of her offering me an apple filled with sin yet irresistibly delicious was seductive, like something straight out of myth. The dense, overwhelming sensuality and lust made it hard to even breathe. Pretending to struggle against the pleasure coming from Seol-young, I furrowed my brows deeply and lifted my head.
“Hng…!”
“Feels good, right? Hng… haa. Auntie feels good too. Just touching Minjun’s cock… I’m so excited I could go crazy. I can’t hold back.”
“Ugh…!!”
“Hah. Minjun-ah. My lovely Minjun-ah. Auntie only needs Minjun. Hng. If Minjun just stays with me, Auntie can do anything for you. Hnyaah. Chup. Chuuup.”
“Hng…!! M-Mother!! That’s…!”
Chomp—. Seol-young suddenly bit down on my exposed neck. Then she started sucking hard, trying to leave a hickey. While it was nice that Seol-young was becoming increasingly possessive of me, this was a bit problematic. I had a date planned with Yuna in the evening, and if I showed up with my neck covered in hickeys when it had been clean just this morning, her favorability would definitely fluctuate wildly.
‘Haa… Can’t be helped.’
Because of Seol-young’s sudden action, I had no choice but to end today’s act here. I activated every skill I had been holding back and firmly grabbed Seol-young’s head with both hands as she sucked on my neck, then forcefully kissed her. This was the real Kim Minjun—completely different from the good son-in-law I had been showing her until now.
“Mmph…!!! Mmmph!! Haah, hup…! Chuuup!! Chuuup.”
“Chup. Chuurp. Chuu, chuuup.”
Startled by the sudden forceful push, Seol-young’s lips, which had been stiff at first, gradually relaxed. We embraced each other tightly and kissed for a long time. It was an intensely adult kiss—so intense that simply calling it an “adult kiss” felt insufficient.
“Mmm. Chuuup. Chuuap. Chup. Chuurp, chup.”
“Chup. Chuuup. Chup.”
We overlapped our tongues without any gaps and devoured each other. We licked teeth and gums thoroughly like brushing, endlessly craving each other’s saliva as if it were holy water. Whenever thick saliva mixed with each other’s essence stretched like a thread from our touching lips, we sucked it into our mouths as if competing to see who would swallow first.
Five minutes, ten minutes. I didn’t know how long it lasted. Time didn’t register. The kiss was so deep it made my brain feel mushy. Yeah, even among adults, how many people had ever kissed like this? Unless they were extremely perverted adults, they probably couldn’t have experienced such a dirty, sexy kiss.
“Chuuup. Chuur—. Huaa… haaah.”
“Haaah. Haa.”
When our lips had swollen from the intensity, we pulled away at the same time as if by agreement. After roughly swallowing the saliva that had been swirling in our mouths, we looked ahead. There was Seol-young with a completely melted expression.
“Hng. M-Minjun-ah…”
It was Seol-young with her mask removed. She was still lewd, but there was also a hint of shyness. The shame of genuinely going into heat for a man much younger than herself, yet the excitement and pleasure that shame couldn’t suppress. She was probably feeling that complex, subtle emotion.
‘Nice. This kind of thing. Still, I should savor it.’
I really was a pervert. When I looked at a beautiful woman whose emotions were fluctuating like never before because of me, acting purely on instinct, I felt endless happiness and excitement. If I just took Seol-young right here and now as I pleased, I could turn her into my slave anytime. But I wanted to enjoy this roleplay with Seol-young not just today, but occasionally in the future as well. The forbidden romance between a prospective son-in-law and prospective mother-in-law resonated deeply with me. So I activated the Leader’s Brainwashing skill and looked at Seol-young as I cast it.
“From now on, all memories of being with me will be altered by tomorrow. No matter what I do from now on, you’ll remember it as you seducing the hesitant me and having your way with me. Understand?”
“Yes, I understand.”
After consuming some obedience points to pre-arrange the memory alteration, I roughly splashed water on my body and carried the dazed Seol-young, whose brainwashing had worn off, in my arms toward the master bedroom. Water was dripping from both her body and mine, but it would probably dry naturally once we rolled around on the bed. The bedding would get messy, but since it wasn’t even our house, who cared?
“Ung… M-Minjun-ah?”
“Call me ‘husband.’ It sounds better.”
“…Yes. Husband.”
Seol-young, who had regained consciousness in my arms, called my name in a confused voice. I gave her orders in a very masculine way, the complete opposite of how I had been acting until now. Startled by my completely changed demeanor, Seol-young flinched, but soon buried herself deeper into my embrace with a shy expression while obeying my words.
“Kyaa. H-Husband.”
I lightly tossed Seol-young onto the bed and slowly crawled toward her.
“It’s because Auntie did something wrong. I clearly refused… but because of Auntie, it feels like I’ll never be able to face Yeonju again. It’s all Auntie’s fault.”
“I-I’m sorry, Husband. I just… I just like you so much… I love you so much…”
“Right. I understand, so take responsibility. Since Auntie ruined everything, take full responsibility. Got it?”
“Yes. Husband. I understand.”
At my words about taking responsibility, Seol-young’s jet-black eyes sparkled. She seemed to already anticipate how I would demand that responsibility.
‘Hoo, this is fun. Blackening play is fun too.’
The concept was that the good son-in-law, overwhelmed by unbearable guilt, suddenly blackens and actively fucks Auntie. Since Seol-young’s memories would be altered tomorrow anyway, I figured I might as well do whatever I wanted in the meantime. This feeling wasn’t bad either. It had a different flavor from before. Roleplaying like this, fully immersing myself in the scenario while fucking a woman from various perspectives, definitely had a unique kind of fun.
“Suck it. I’ll let you suck the cock you wanted so badly.”
“Yes, Husband. Cock… I want cock. Thank you for letting me suck your cock.”
I brought my massively erect, menacing cock right in front of Seol-young’s face and commanded her. Seol-young, who had gotten on all fours like a dog on the bed and leaned forward, opened her mouth wide and slowly took my cock in.
“Mmm… haah… chuuup…”
“You’re only going to eat the glans? Swallow it deeper. It’s what Auntie wanted, so you should work hard.”
“Mmm… I underthtand. Mmph…! Haah… mmph… keck. Keck, keck.”
Even while struggling to swallow my cock, Seol-young was a woman who knew how to turn that very struggle into an arousing point. With tears welling in her eyes from trying to take the massive shaft, she looked up at me, and that expression was exactly like a puppy begging for praise.
“Mmph… keck, keck. Haa. Uuuuung…”
She kept her eyes fixed on me and continued swallowing my cock despite gagging, but no matter how hard she tried, her small lips couldn’t even take half of it. After desperately trying to swallow more, Seol-young eventually looked up at me with my cock still deep in her mouth and slightly shook her head. It was a signal that she had reached her limit. Normally I would have forced it deeper, but even if I was playing the blackened role, going that far was too much for someone whose true nature was kind. I let out a resigned sigh and pulled my cock out of Seol-young’s mouth.
“Haa… You said you’d do anything, but you can’t even swallow a cock properly?”
“Hueh, haah. Hng… I’m sorry, Husband. I’ll try swallowing again. This time I can do it.”
“It’s fine. Since you’re using your mouth, just lie down on the bed.”
“Yes. I understand.”
