The Mother-in-Law's Mansion Tour
"Honey!!"
Once the conversation—if you could call it that—with my mother-in-law concluded, Yeonji and a woman named Yeonhee entered the reception room. Since I had already received permission for our marriage, I told Yeonji the news, and she hugged me, genuinely overjoyed.
"Hehehe."
"Ah! ...U-um! Thank you, Mom."
When my mother-in-law smiled at Yeonji’s adorable reaction, Yeonji blushed, feeling shy, and pulled away. She then went straight to her mother and hugged her, brimming with happiness.
"Thank you, Mom! I really love him so much."
"Yes... I know, dear. And I could feel that Juhyun truly loves you, too."
My mother-in-law stroked the hair of the daughter nestled against her chest.
'What a sight... A strangely erotic sight.'
A daughter purely happy about getting permission to marry, and a mother looking on with a satisfied smile. If you just heard the description, it would sound like a beautiful scene. But with my mother-in-law’s massive, heavy breasts pressing into her daughter, and Yeonji’s own breasts being pushed up so they were visible from behind, I couldn't help but swallow hard.
'Just a few minutes ago, I was doing that with her mother right here...'
Recalling that her mother had been sucking my cock in this very room only moments ago, while I was now in the same space as Yeonji, brought a mix of guilt and a strange, perverse sense of immorality.
'What am I going to do from now on...'
I was in a situation where I had been forced into training my mother-in-law as a sex slave in order to marry Yeonji. Even though it was a situation I couldn't refuse, I had to admit to myself that I didn't exactly hate it, either.
'I shouldn't be doing things like this while Yeonji is around...'
Honestly, even earlier, I couldn't properly brush off my mother-in-law’s seduction. She was, quite frankly, just as much my ideal type as Yeonji was. With her tall, 170cm frame and breasts that were similar to or even larger than Yeonji’s, she was so well-maintained that it was hard to believe she had an adult daughter. When I first saw her, I honestly thought she was Yeonji’s older sister.
'Looking at them like this, they’re actually quite different styles, aside from their faces and breasts... Do I just have a thing for big breasts?'
Perhaps because of the height difference, the mother and daughter looked alike, but the atmosphere they exuded was quite different. If there was one commonality, it was those massive, heavy breasts. I began to wonder if I had been completely captivated by them.
'Come to think of it, this woman is also quite...'
I didn't know who the woman named Yeonhee was, but she stood quietly to the side, dressed in a professional suit and skirt. Furthermore, while not quite on the level of the mother-daughter pair, she had remarkably large breasts that caught my eye. I had looked at her without thinking, and when our eyes met, I hurriedly looked away.
"Ah, my apologies for the late introduction. This is Yeonhee. She is my..."
"Greetings, Juhyun. I am Lee Yeonhee, the exclusive secretary to Madam and the young lady."
Before my mother-in-law could finish her introduction, the woman named Yeonhee spoke, identifying herself as the exclusive secretary.
"Hello. I’m Lee Juhyun... I look forward to working with you."
"Yes, Juhyun."
With her slightly cold demeanor, Yeonhee looked every bit the part of a professional secretary.
"Yeonhee-unnie! Really!"
At Yeonhee’s self-introduction, Yeonji looked a bit pouty, and my mother-in-law wore a slightly bitter expression, but the secretary didn't seem to care at all.
"Then, I have work to attend to, so I will excuse myself for a moment. Please let me know if you need anything."
With a haughty bow, the secretary turned and walked away.
"Sigh... I’ll tell you about Yeonhee later."
"Unnie..."
Yeonji looked a little lonely, but perhaps because this wasn't a one-time occurrence, she quickly returned to her bright self.
"Then, let’s make Oppa’s room the one right next to mine!"
"No."
"Eh? Mom?"
Since the mansion had more than enough empty rooms, it didn't matter which one I took, but Yeonji, wanting to be closer to me, suggested the room right next to hers. My mother-in-law, however, flatly refused.
"You aren't married yet. Besides, you’re still too young to get married right away. I’ll allow you to live together and I’ve given my permission for the marriage, but the formal ceremony will wait until after you graduate. Keep that in mind."
"Uuu... Okay, Mom..."
It might sound strict, but there was nothing wrong with what she said. I was in my mid-twenties, so it wouldn't be an issue for me, but Yeonji was still a sophomore in college. It was true that she was still young, so I agreed that it was right to postpone the ceremony.
'But why the room assignment...'
Even though we weren't married yet, we were a couple who would eventually share a room, so it wouldn't have been strange for me to take the room next to Yeonji’s. Yet, my mother-in-law had been adamant.
"I’ve given my permission for the marriage, but honestly, I don't know much about you yet, Juhyun... So I’m going to keep you in the room next to mine and keep an eye on you."
'So that’s the plan...'
My mother-in-law, who desired to be trained by me. She had made up various excuses to Yeonji, but in the end, it was a plan to keep me in the room next to hers so she could be trained by me more easily every night.
'Look at that gaze...'
My mother-in-law looked at me with a lewd smile, hidden from Yeonji. It seemed I couldn't escape the palm of her hand.
'Well, there’s no other way...'
For someone who had lived a normal life, training my mother-in-law was a heavy burden on my conscience. Just being in this space with Yeonji made my heart ache, but since I had no other choice, I had accepted the situation for now.
'At least she doesn't do anything in front of Yeonji, right?'
My mother-in-law, who had been on her knees earlier, begging me to be her Master, wasn't showing any of that lewd behavior in front of Yeonji, which was a relief.
"Then, I’ll give you a tour of the mansion, Juhyun... Yeonji, you go to your room and work on your assignments."
"But I wanted to be the one to show him around..."
"If you do it, you won't give a proper tour and will just be lovey-dovey the whole time."
"Uuu... Okay... See you in a bit, Oppa."
"Oh? ...Yeonji, you can come al—"
"Yeonji, go on upstairs now."
"Yes..."
As we were left alone, I tried to keep Yeonji there, but my mother-in-law spoke faster, and Yeonji headed up to her room with a disappointed look on her face.
"Now we’re all alone... Master♥"
As soon as Yeonji and the secretary disappeared, my mother-in-law revealed her true nature.
"M-mother-in-law... shouldn't you be giving me the mansion tour right now..."
"There’s plenty of time for that... Besides, it seems you weren't satisfied with what we did earlier, Master♥"
"T-that’s, it’s just..."
Watching the mother-daughter pair earlier had caused me to get semi-erect again. I had been trying to act like nothing was wrong by keeping my hands politely folded, but she had already noticed.
*Slide*
"Ugh... M-mother-in-law..."
Without a care, she moved her hand toward my crotch and stroked over my trousers. At her touch, my cock began to grow even larger.
"The staff is away today, so... it should be fine to walk around like this, right?♥"
*Zzzip*
"M-mother-in-law, wait a second?!"
She used a hand technique so pleasurable I couldn't resist. She unzipped my pants and pulled my cock out.
"It’s truly an amazing cock, no matter how many times I see it♥"
*Stroke, stroke, stroke, stroke, stroke, stroke*
She looked at my cock with the expression of a girl falling in love. As she moved her hand to give me a proper handjob, a wave of intense pleasure washed over me.
'She’s doing this the moment Yeonji leaves... But it feels so good!'
My brain told me I had to refuse, but her hand technique was so good that I couldn't resist. I felt pathetic, but her touch was truly incredible.
"Even though you came so much earlier, you’re still this hard♥"
My cock, never satisfied with just a round or two, was standing as if it were the first time, despite having ejaculated heavily earlier.
"Then, let me show you around the house♥"
"I-in this state?"
"Oh my... Are you embarrassed?"
"Of course I am!"
It would be stranger if I weren't embarrassed to be walking around with my cock out while being jerked off by my mother-in-law.
"Then, to make it fair♥..."
*Slide... Pop*
"M-mother-in-law!?"
She smiled, grabbed the bodice of her dress, and pulled it down slightly, exposing her breasts.
"This makes it fair, right?♥"
"Gulp... Y-yes..."
Her breasts, which had been precariously hidden inside her dress, were now revealed.
'Her breasts... and her nipples!!'
It was as if she were showing me what Yeonji’s breasts would look like when she became more mature. They were slightly larger than Yeonji’s, and the areolas and nipples were a bit bigger, too. The color was a deep, dark pink, and just looking at them made my excitement impossible to suppress.
"It seems you like them, Master♥ Hehehe♥"
As I stared intently, she smiled, clearly pleased. She deliberately pushed her chest forward, flaunting them even more.
"Look, even my nipples have hardened like this♥"
*Poke*
"Aang♥"
She let out a lewd moan as she teased her own nipples, seducing me. My cock was throbbing madly, leaking pre-cum. Her hand slowly stroked my cock, trying to calm it down.
"Then... let’s go♥"
"Ugh... Yes, mother-in-law..."
In the end, completely distracted by her seduction and her breasts, I began to walk through the house following her. Leaving the reception room and entering the hallway, my heart raced because I knew I was doing something I shouldn't be, but between her lewd breasts and the handjob I was receiving, my instincts had completely overridden my reason.
I walked down the hallway with her, having lost all will to resist. And from this moment on, I realized one thing for certain:
I loved breasts... and I loved them even more when they were so massive they were called "explosive breasts."
