Time passed, and evening arrived. Yeonji, who had gone to school, and Yeonhee, who had headed to work, both returned home.
"I'm home, Oppa!! ♥"
"I'm home, Madam... Juhyun."
Of course, my mother-in-law and I had already cleaned everything up in advance, greeting them as if nothing had happened, so there were no issues...
Still, it felt wrong to fool around with my mother-in-law and then face Yeonji like this...
Yeonji, completely oblivious, hugged me with delight, while Yeonhee, though she didn't show it on her face, seemed faintly displeased as she greeted us.
"Welcome back, Yeonji... and Yeonhee, you must be tired from work."
"No, I still have things to do, so..."
Seeing Yeonhee brush past us and head inside, Yeonji and my mother-in-law looked a bit disappointed, but they didn't seem inclined to force a change in her behavior.
"Oppa is such a good person... I wish Unni would realize that soon."
"Haha..."
Those words—"good person"—made me feel a twinge of guilt.
After all, not long ago, I'd been calling my mother-in-law "Mom" while engaging in depraved sex, and that morning, while jogging with Yeonhee, I'd been sneaking glances at her ass and chest, getting hard in the process.
I guess I'm too weak when it comes to my instincts...
Growing up in the orphanage, I'd always endured not having what I wanted, and even after years of grueling delivery work, I'd lived frugally without wasting a penny. I'd thought I had strong patience and self-control. But since coming here, I'd realized my endless vulnerability to my masculine urges.
It might be hard to get close to Yeonhee for a while...
From the start, she hadn't seemed to accept me as Yeonji's boyfriend, and after seeing me get an erection, her opinion of me must have sunk even lower.
So, it could be difficult to bridge that gap easily, but I decided to trust that time would resolve it to some extent and pushed the thought aside for now.
"Hehe ♥ Oppa, you didn't forget we have a date tomorrow, right?"
Of course not. It's the weekend, so let's have fun.
"Yeah!"
It was my first weekend since arriving at this house, but honestly, it didn't feel that special—I'd been living like a total slacker. Still, I was in a good mood because I could finally enjoy a relaxed date with Yeonji after so long.
"Whoa! A date just for the two of you? Can I tag along?"
"Ah, no, Mom! We'll go together next time!"
My mother-in-law teased with a playful smile.
Yeonji, not wanting any interruptions on her first proper date in ages, responded with a hint of annoyance.
"And Mom, you already went out alone with Oppa."
"Haha, that's true."
Yeonji sounded a bit jealous, her tone laced with envy over the time my mother-in-law and I had spent alone at the department store.
Come to think of it, that was quite the date...
I felt bad for Yeonji, since it had been a lewd outing where I'd temporarily played the role of my mother-in-law's husband.
This time, I'll make sure it's a date Yeonji truly enjoys!
I'd done plenty to make her feel bad over the past few days (mostly involving my mother-in-law), so I vowed to make this date one she'd be unconditionally thrilled with—as a form of atonement.
"Tomorrow's date is just for Yeonji and me, so please bear with it, Mother-in-law."
"Haha, I will."
"Oppa! ♥♥"
My mother-in-law laughed as if amused by my firm tone, while Yeonji beamed with joy.
"Don't stay up too late tonight, since you're looking forward to tomorrow."
"Okay, Mom! And I'm not a kid anymore!"
"I know... I found that out just yesterday ♥"
"Uuuu, I'm heading to my room."
Yeonji, embarrassed to the point of blushing red at the mention of her first time, bolted to her room as if escaping.
Thud, thud, thud.
It even takes her a while to run away...
Being a mansion, her retreating figure was visible for quite a while as she fled to her room.
So, are you planning to stay out overnight tomorrow?
"Huh? I'm not sure about that..."
"Well, now that you're a couple who've gone all the way... you could spend the night together without worry ♥"
"Urgh..."
It's common for couples to go on weekend dates and crash at a motel to spend the day together. We'd only just had our first time, so it wasn't strange for us to spend a night out like other couples.
And this has parental approval... well, from one parent...
My mother-in-law acknowledged it as natural for us to have sex, since we were getting married anyway.
...From her perspective, with our master-servant relationship and her somewhat twisted sexual desires, she'd want Yeonji and me to deepen our bond through things like sex.
"Since you'll be with Yeonji all day tomorrow, Master... please spend tonight with me ♥"
"...Yes."
I wanted to refuse, but when she pressed her large breasts against my arm while speaking, I nodded without thinking.
"Hehe, then look forward to it ♥"
In the end, I sighed at myself for failing to resist her seduction and giving in.
.........
"Should I shower soon...?"
After spending time as usual and with bedtime approaching, I stripped off my clothes to shower in the bathroom attached to my room.
I need to wash more thoroughly since I have a date tomorrow.
I was a bit excited—it was my first date with Yeonji in a while.
I'd done plenty to upset her over the past few days, so I resolved to do my best to make amends, starting with cleaning myself up.
Knock, knock.
"Oppa, are you there?"
"What's up at this hour?"
I missed you, Oppa ♥
Yeonji, who'd come to my room, smiled brightly and hugged me the moment she saw me.
"Are you about to shower?"
"Yeah, I was going to wash up and go to bed."
"Then... should we shower together?"
"Sure."
"Yeah!"
We'd showered together plenty of times, so it wasn't anything special, but it was still nice.
"I'll go grab my clothes ♥"
Yeonji, speaking quietly to avoid being caught by my mother-in-law, fetched her change of clothes and joined me in the bathroom.
Rustle, rustle, rustle.
"It's amazing no matter how many times I see it..."
Yeonji stripped without a care.
We'd seen each other naked countless times, but honestly, my desire surged to unbearable levels every time.
Her youthful appearance and slightly short stature contrasted with her large breasts that jiggled with every movement as she undressed, and with her firm, plump ass right before my eyes, my cock naturally swelled.
"Ah ♥..."
Yeonji, now fully naked, blushed as she stared at my erection.
"Now... I can take it inside, right? ♥"
"Yeah..."
Before, we couldn't go all the way and were limited to rubbing, but now we'd crossed that line—we could do it properly.
"Oppa ♥..."
The small changing area attached to the bathroom would fill up with just three or four people, but that meant we could be even closer.
Yeonji reached out and stroked my cock.
At first, she'd been disgusted and scared, unable to even look at it properly, but now she smiled as if it were cute and even wanted to touch it herself.
"Should we do it while showering?"
"Yeah..."
"Then let's hurry inside ♥"
Who could refuse when their girlfriend tempts them into shower sex?
At least, I couldn't resist Yeonji's seduction, so I let her lead me into the bathroom.
It was spacious for a room-attached bath, with a large tub big enough for two.
"Oppa's cock worked so hard yesterday, kiss ♥"
"Mmm..."
Yeonji knelt before me and kissed my cock.
It throbbed at the sight of her kissing it like a beloved lover.
"I won't be as unsatisfying as before... you can put it inside me whenever you want ♥"
Ah... that expression.
Yeonji smiled up at me.
It wasn't her usual fresh, cute smile, but a lewd, seductive feminine one.
It was a wicked grin reminiscent of my mother-in-law, and I grabbed her head, entranced by it.
"Suck it."
"Yes ♥..."
I'd used a low, commanding tone without realizing, but Yeonji only shivered slightly and nodded, keeping her lewd smile.
"Kiss ♥ Slurp ♥ Heup ♥ Sluurp ♥ Slurp ♥"
Yeonji began licking and sucking my cock with all her might.
Her small mouth nibbled the head while her red tongue lapped the shaft, continuing her service.
"Oppa's cock, haah ♥ is delicious ♥ Kiss ♥"
My dark desires swelled at Yeonji's lewdness as she sucked my cock, claiming it tasted amazing.
Come to think of it... she was scared of cocks, but... she liked sucking them.
It was a bit ironic, but despite her fear of penises, Yeonji found their taste quite good.
She had a lewd side from the start...
It was unusual for a normal woman to find it delicious, but both Yeonji and my mother-in-law genuinely said cocks tasted great and licked them nonstop.
"Haah ♥ Sluurp ♥ Slurp ♥ Heup ♥"
Yeonji was now utterly absorbed, holding my cock with both hands as she went wild.
The pure smile from moments ago was gone; now she sucked with a lewd, masochistic feminine grin that rivaled my mother-in-law's.
"Puhah ♥... haa ♥... haa ♥ I still can't deepthroat it, so I'll do this for you ♥"
Yeonji lifted her breasts, wrapping them around my cock while nibbling the head with her mouth, servicing me on her own initiative.
"You're doing great—keep going."
"Haah ♥ Yes, Oppa ♥ Haa ♥"
Yeonji used her mouth and breasts together.
Seeing her completely lost in my cock, rubbing it with her tits and sucking with her mouth, filled me with a powerful sense of conquest.
Ah, at this rate, I'll end up treating her like I do my mother-in-law...
My dark desires grew stronger, and without realizing someone was watching us, I drew closer to Yeonji.
