"M-Mother-in-law?? What are you doing here?!"
I was about to shout, but I quickly glanced to the side.
"Mmm… mmm…"
Thankfully, Yeonji hadn't woken up. She was still sound asleep, showing no signs of stirring.
"Hehehe♥ Don't worry, Master♥… Yeonji doesn't wake up easily once she's in a deep sleep… Besides, it seems like you two were pretty intense… She won't be able to wake up any time soon♥"
Finally, my mother-in-law, who had her mouth on my dick, opened her mouth with a lewd smile.
"Even so, this is too dangerous!"
I tried to speak as quietly as possible, but still loud enough for my mother-in-law to hear, but she just stroked my dick and smiled.
"But… it was you who broke our promise first, Master… lick♥"
The promise that my mother-in-law would spend time with me tonight before our date tomorrow.
My mother-in-law was naturally excited at the thought of spending time with me doing lewd things, but I had completely forgotten about the promise because I was with Yeonji.
"B-but I'm with Yeonji, please give me a break!"
"No way♥ lick♥ slurp♥"
I was hoping that she would step back as a mother here, but my mother-in-law had no intention of doing so, not letting go of my dick.
"But… if not today, I won't be able to see you all day tomorrow…slurp♥ I just can't let this dick go♥."
It was only a matter of enduring one day, but like a bitch that had met its master, my mother-in-law couldn't wait a single day and came to me like this.
'If Yeonji wakes up… it's over…'
Of course, my first experience was a strange one with my mother-in-law involved, but that doesn't mean Yeonji knows about or accepts the relationship between me and her mother.
Her mother had only helped us from the side, and she had no idea that I had used her mother as a cum dumpster that day, having rough sex with her to sleep with her.
No matter how much Yeonji loves and trusts me and her mother, she was not stupid enough to accept this situation without a second thought.
If she were to wake up and see me and her mother having sex…
'I'm done for…'
Her boyfriend was having lewd sex with her mother, not even caring that she was sleeping next to them?
It would be over, and I wouldn't have a word to say even if I never saw her again.
That's why it would be best if my mother-in-law would step back and hold back, but…
"Master's dick is so delicious.♥ Next time, I want to suck your dick after you've had sex with Yeonji, covered in her juices and your cum.♥"
She was completely lost in my dick, unable to let go, and was seducing me with lewd words.
'She's definitely not going to back down here…'
If she were the type to prioritize reason in this situation, she wouldn't have come here in the first place.
But my mother-in-law, who has a masochistic female instinct as strong as her reason, was even more excited by this precarious situation.
Even now, she was boldly sucking my dick naked under the blanket, looking at me with a lewd smile that's clearly visible.
"But… you did it with Yeonji earlier, right?"
"Yes…"
There was no need to lie now, so I told her honestly. My mother-in-law looked like she was thinking for a moment.
Of course, while still sucking my dick…
"But how is your dick still so hard?… Your balls are full too, slurp♥."
"Ugh!?"
My mother-in-law grabbed my dick and shook it, licking and sucking one of my balls.
Her lewd service, as if showing that she was less than my balls, made me moan without realizing it.
'I think I've learned wrong from my mother-in-law…'
I was not just nervous in this precarious situation, but I was also getting more excited.
There was the tension of possibly being caught by Yeonji, but that was why I had a growing desire to treat my mother-in-law even more roughly, like an onahole.
"How much did you do with Yeonji? Slurp♥ mwah♥"
"Well…"
I briefly told my mother-in-law about what happened with Yeonji in the bathroom.
I told her that I had cum twice and wanted to do more, but Yeonji had fainted, so I couldn't do more and came to bed. After hearing everything, my mother-in-law smiled as if there was nothing she could do.
"I'm sorry, Master… It seems like Yeonji isn't used to it, so it's hard for her to last long."
"It's okay… I think it's natural…"
It wasn't just a normal sex session in the bathroom as she was roughly fucked while being held down, so it was natural that she couldn't handle it.
"Today, I, as her mother, will release everything that's built up in you, Master♥… So please don't hesitate and use me instead of Yeonji.♥"
'That's her goal…'
Apologizing was just an excuse, and her true desire was to be used even more humiliatingly.
A request to use herself, her mother, to satisfy what her daughter couldn't.
The desire of a masochistic female who just wants to be used as an onahole instead of her daughter was clear in her eyes.
"*slurp*♥ mwah♥ gulp♥ slurp♥ I'm sorry for not being able to do it for you when you're so full.♥ Slurp ♥ Gulp.♥"
My mother-in-law was kissing my dick and balls, acting like she was apologizing on behalf of her daughter.
"Please use my body… the mother's body, to satisfy what my daughter couldn't ♥… If you want, call me Yeonji like you did earlier instead of her. ♥♥"
"Ugh!"
It was a lewd seduction that went too far.
She was now a horny female who existed only to be used by her master, who would be happy to be used to imagine her daughter and masturbate, all to satisfy her master.
"Now… please use me as much as you want. ♥♥"
I couldn't hold back any longer at the sight and actions of my mother-in-law, who was clinging to my dick with a lewd smile on her face.
"Okay… Then I'll use your pussy instead of Yeonji's, so spread it right now!"
"Yes, Master♥"
My mother-in-law, who was genuinely happy to be ordered around by her son-in-law, slowly moved up and brought her pussy to my dick.
"It's already wet and ready to use, Yeonji's warm pussy♥"
My mother-in-law was deliberately using Yeonji's name to excite me even more.
"Don't look at me… Look at Yeonji and use me as much as you want.♥"
My mother-in-law turned my head to the side, and there was Yeonji's pure face, still sleeping soundly, not knowing anything.
"Ah♥ Oppa's dick is so big, I love it♥"
My mother-in-law was deliberately using a voice similar to Yeonji's and calling me "Oppa."
'Just like when she imitated Yeonhee last time… Her impersonation is so good!'
Listening to my mother-in-law's impersonation, which made me feel like I was really hearing Yeonji, my dick was slowly entering her pussy.
"Haa♥ Heh♥ Use Yeonji's onahole pussy to cum until you're satisfied, Oppa♥."
"Ugh! Yeonji isn't an onahole! She's not a sow who goes crazy for dick like my mother-in-law!"
Squish...Squish...Squish...
"Haa♥ Heh♥ No, Yeonji's pussy is an onahole pussy.♥ It's a sow pussy that leaks juices whenever she sees Oppa's dick.♥"
My mother-in-law was stimulating me by deliberately making her daughter sound like a lewd female bitch.
Squish...Squish...Squish... Squish
"I love being fucked by Oppa's dick♥ I want to live as Oppa's onahole forever♥"
"Ugh!!"
Yeonji, who was showing the same lewdness as my mother-in-law (well… it was my mother-in-law), hearing her masochistic female remarks, I was more excited than angry.
It was just an imagination, but as I pictured the faces of the two females kneeling in front of me, looking up with lewd expressions, my dick became even harder.
"Haa♥ Haang♥ Heh♥ Cum inside me♥ Cum inside my onahole pussy and get me pregnant…Breed me, Oppa♥"
"Ugh!! Yeonji!"
A dark desire that leaked out even as I tried to suppress my voice.
Looking at Yeonji's pure face, still asleep and unaware, that desire only grew stronger.
Slap!! Slap!! Slap!! Slap!!
Slap!! Slap!! Slap!! Slap!!
"Haaahhhhhh?!♥"
Slap!! Slap!! Slap!! Slap!!
Slap!! Slap!! Slap!! Slap!!
As I cummed inside my mother-in-law's pussy, my mother-in-law was trembling with joy at the strong male's ejaculation.
"Oppa's… Master's cum♥ It's filling my sow's belly♥♥"
In the end, my mother-in-law, who had been acting as Yeonji, collapsed and made a vulgar ahegao face.
"Ugh… Oppa?"
"Huh?!"
Yeonji was slowly starting to open her eyes.
'No!? What do I do!? Crazy!? Damn it!? What!?'
Yeonji was opening her eyes while I was too careless.
She still looked half-asleep, with a dazed expression, so it seemed like she was still half-asleep.
"Ah… it's still night, so let's sleep."
"Yeah… but… I heard Mom's voice…"
Yeonji was blinking her eyes, looking for her mother.
I was frozen, unable to do anything, when my mother-in-law opened her mouth.
"Yeah… Mom's here… So let's keep sleeping."
"Okay… Mom… I understand… good night…"
With one word from my mother-in-law, Yeonji closed her eyes again and fell asleep.
"Haa♥… Haa♥… That was… dangerous♥."
Twitch… Twitch… Twitch…
I was relieved that we could have been caught if she had woken up a little more, but…
"Haa♥… Haa♥… Haa♥"
My mother-in-law was climaxing, clenching her pussy tightly.
My mother-in-law was even more excited by the situation where her daughter could have caught her making a vulgar sow face while being ejaculated into by her son-in-law.
Squish...Squish...Squish...
I couldn't hold back any longer at my mother-in-law's excessive lewdness, and I grabbed her ass tightly and moved up and down.
"Huu♥ Haa♥ Ugh♥"
My mother-in-law, who was being used like a real onahole while suppressing her moans as much as possible, was finally released after being ejaculated into three more times.
She then returned to her room with trembling legs.
