A Secret Visitor in the Night
‘Hey, Mum-in-law, what on earth are you doing here?!’
I shouted and glanced frantically to my side.
‘Mmm... mmm...’
Fortunately, Yeon-ji hadn’t woken up; she was fast asleep and showed no sign of waking.
“Hehehe♥ Don’t worry, Master♥... Yeon-ji doesn’t wake up easily once she’s had a deep sleep, does she?... Besides, after we’ve just had such a wild time together... she’s not going to be able to wake up at all♥”
Finally pulling her mouth away from my cock, my mother-in-law opened her mouth with a lewd smile.
“Even so, this is far too dangerous!!”
I spoke as quietly as possible, yet clearly enough for my mother-in-law to hear, my voice tinged with anger, but she merely stroked my cock and smiled.
“But... you were the one who broke the promise first, Master... *slurp*♥”
“Ugh?!”
The promise was that she would spend time with me tonight before our date tomorrow. Naturally, she had been full of anticipation, expecting to spend the time doing naughty things, but she had completely forgotten about that promise whilst she was with Yeon-ji.
“B-but I’m with Yeon-ji right now, so please just give in this once!”
“No way♥ Slurp♥ Hmmph♥”
I’d hoped she’d take a step back here, acting simply as a mother-in-law and a mum, but she seems to have no intention of doing so, refusing to let go of my cock.
“But if not today, I won’t see my master all day tomorrow… Hah♥ I just can’t let this pass♥”
It’s only a matter of holding out for a single day, yet here she is, unable to wait even a day like a dog that’s met its master, coming to find me like this.
'If Yeon-ji wakes up... it’s all over...'
Of course, my first experience itself took the strange form of having my mother-in-law involved, but that doesn’t mean Yeon-ji knows about or accepts the relationship between me and my mother-in-law.
My mother-in-law merely helped us from the sidelines; she has absolutely no idea that I used her as a semen bin whilst having rough sex with her that day, purely for my own pleasure.
No matter how much Yeon-ji sincerely loves and trusts me and my mother-in-law, she isn’t stupid enough to accept a situation like this without batting an eyelid.
If she were to wake up and see me and my mother-in-law in the throes of passion...
‘It would be the end for us...’
She’s sleeping right there, and her mum and her boyfriend are having lewd sex without a care in the world? Not only would we break up immediately, but she’d have every right never to see me again.
That’s why, for now, it’s best for my mother-in-law to take a step back and put up with it...
“Master, your cock tastes so good ♥ Next time, I want to have sex with Yeonji and suck your cock covered in pussy juice and cum ♥"
She’s completely obsessed with my cock, unable to tear herself away, seducing me with lewd words.
‘She’s absolutely not the type to back down here...’
If she were the sort of person who prioritised reason enough to quietly back down in a situation like this, she wouldn’t have come in the first place.
However, as a mother-in-law who possesses a masochistic female instinct as strong as her reason, she actually gets even more aroused by this precarious situation.
Even now, she’s boldly sucking my cock naked under the duvet, gazing at me with a lewd smile that’s plain to see.
“But… you were with Yeon-ji earlier, weren’t you?”
“Yes…”
There was no point in lying at this stage, so I answered honestly. My mother-in-law looked as though she was pondering something.
Whilst still sucking my cock, of course...
“But your cock’s this stiff?.....And your balls are full to bursting too, hmm♥”
“Ugh!?”
My mother-in-law, holding my cock in her hand and stroking it whilst licking and sucking one of my balls with her mouth, giving me a blowjob.
It was such a lewd service, as if she were showing that she was a being inferior to my balls, that I couldn’t help but let out a moan.
‘I think I’ve been completely misled by my mother-in-law...’
In this precarious situation, I’m just as excited as I am nervous.
There’s the tension of possibly getting caught by Yeon-ji, but precisely because of that, a desire to treat my mother-in-law roughly, like a sex toy, is slowly creeping up on me.
“How long did you go on with Yeon-ji? Hmmph♥ Suck♥”
“Well...”
I briefly recounted to my mother-in-law what had happened with Yeon-ji in the bathroom.
I’d come twice in total and wanted to go on, but Yeon-ji had fainted, so I couldn’t continue and had to stop there before coming to bed. Having heard the whole story, my mother-in-law smiled as if to say it couldn’t be helped.
“I’m sorry, Master… It seems Yeon-ji isn’t used to it, so it’s hard for her to go on for long.”
‘It’s fine... In fact, it’s only natural...’
Not the ordinary sex in the bathroom; she’d been roughly taken whilst held down so she couldn’t escape, so it was only natural she couldn’t hold out.
‘Today, instead of Yeon-ji, I, her mother, will relieve all the pent-up desire you’ve built up, Master♥... So please don’t refuse—use me instead of Yeon-ji♥’
'So that’s the real aim...’
Apologising was just an excuse from the start; her true desire is to be used in an even more humiliating way.
A request for me to satisfy her—her mother—because her daughter couldn’t.
The desire of a masochistic female who simply wants to be used as little more than a sex toy in place of her daughter is plain as day to me.
‘Haaah♥ Chooop♥ Uuuh♥ Heeep♥ I’m so sorry I couldn’t do it for you when you’ve built up so much like this♥ Haaah♥ Uuuh♥’
My mother-in-law, kissing my cock and balls as if fawning over them, apologising in her daughter’s place
‘Please satisfy yourself using this mother’s body, as my daughter failed to do so♥.....If you wish, please call me Yeonji instead of her, just like before♥♥’
‘Guh!’
An obscene temptation that has crossed the line
A female who exists solely to be used by her master, who would gladly accept being used for masturbation whilst imagining her daughter, all to satisfy her master
‘Now... please use me as you please♥♥’
Seeing the mother-in-law clinging to my cock, her lewd smile never leaving her face, I could no longer hold back.
‘Fine... then I’ll let you use my cunt instead of Yeon-ji, so get on it right now!’
‘Yes, Master♥’
Twitch, twitch, twitch
Genuinely delighted to be spoken to informally and given orders by her son-in-law, my mother-in-law immediately climbed up slowly and pressed her pussy against my cock.
“It’s Yeon-ji’s warm, wet pussy, already dripping with moisture and ready for use♥”
My mother-in-law deliberately used Yeon-ji’s name to arouse me even further
“Don’t look at me… just look at Yeon-ji and use me however you like♥”
My mother-in-law turned my head to the side, and there I saw Yeon-ji’s innocent face, sleeping soundly, still unaware of anything.
Squeak
“Ahh♥ I love it when your cock is big, Oppa♥”
My mother-in-law, deliberately imitating Yeon-ji’s voice as she called me ‘Oppa’
'Just like when she was imitating Yeon-hee last time... she’s so good at impressions!'
Listening to my mother-in-law’s impression, which made me feel as though Yeon-ji helium herself were speaking, my cock slid deeper and deeper into her pussy.
“Ahh♥ Heh♥ Oppa, jerk off into Yeon-ji’s pussy until you’re satisfied♥”
“Guh! Yeon-ji isn’t a sex toy! She’s not a slut who goes mad at the mere sight of a cock like you are, Mother-in-law!”
Squelch, squelch, squelch, squelch
“Ahh♥ Heh♥ No, Yeon-ji’s pussy is a sex toy pussy♥ It’s a slutty pussy that drips with juices the moment it sees Oppa’s cock♥”
My mother-in-law, deliberately provoking me by speaking as if she were turning her own daughter into an even more lewd female.
Squelch, squelch, squelch, squelch, squelch
‘It feels so good getting fucked by your cock♥ From now on, I want to live my whole life as your sex toy♥’
‘Guh!!’
Yeonji displaying the same lewdness as my mother-in-law (well... she is my mother-in-law, after all)
Hearing her speak like such a masochistic bitch, rather than making me angry, it actually aroused me even more.
It was merely a fantasy, but as I pictured the faces of the two bitches kneeling before me, gazing up at me with lewd expressions, my cock grew even harder.
‘Ahh♥ Ahh♥ Heh♥ Cum inside me♥ Cum inside my pussy—your very own personal onahole—and get me pregnant♥’
‘Guh!! Yeon-ji!’
A dark desire that seeps out despite my attempts to stifle my voice
Seeing Yeon-ji’s innocent face, sleeping oblivious to everything, only makes that desire grow stronger.
Splash splash splash splash splash
‘Haaaaaah?!♥’
Twitch twitch twitch
As he came inside his mother-in-law’s pussy, she trembled all over with joy at the powerful male ejaculation
"My brother’s... Master’s cum♥ It’s filling this sow’s womb to the brim flux♥♥"
Finally, her act of playing Yeon-ji crumbles, and she makes a vulgar, ecstatic expression in her joy.
‘Mmm..........Brother?’
‘Eh?!’
Yeon-ji slowly began to open her eyes.
‘No!? What do I do!? Are you mad!? Damn it!? What the hell!?’
While I was completely caught off guard, Yeon-ji opened her eyes. With a dazed expression, her eyes barely open, she still looked as if she were half-asleep.
“Ah, it’s still night, so let’s go back to sleep.”
“Yeah..... But.... I heard Mum’s voice......”
Yeon-ji, blinking her eyes, looked for her mother-in-law.
I froze in place, unable to do anything, when her mother-in-law spoke up.
“Yes… Mum’s here… So let’s just go back to sleep.”
“Okay… Mum… I understand… Snore…”
At her mother-in-law’s words, Yeon-ji closed her eyes again and drifted back to sleep.
‘Haa♥.....Haa♥.....That was... close♥’
Twitch, twitch, twitch
I’m relieved that if she’d woken up just a little longer, we might have been caught...
‘Haa♥...Haa♥......Haa♥’
My mother-in-law is clenching her pussy tightly as she reaches climax.
She’s even more aroused because she could have been caught by her daughter wearing that vulgar, slutty expression whilst being made to come by her son-in-law.
Squeak, squeak, squeak, squeak
Unable to withstand my mother-in-law’s outrageous lewdness any longer, I gripped her arse firmly and began thrusting up and down.
‘Huh♥ Ah♥ Uh♥’
Struggling to stifle her moans as much as possible, my mother-in-law—who was truly being used like a sex toy—was finally released only after being made to come three more times, and she returned to her room on trembling legs.
