With My Sister-in-Law (2)
I felt a strange, gratifying thrill at the knowledge that I had made a woman wet.
For a moment, confidence surged through me, and my hand tightened as I slid my palm over her body. Then, gathering my nerve, I pushed a finger inside her.
“Ah….”
The instant my finger entered her, I felt the warmth and slickness of her body close around it, and I began sliding it in and out the way I had seen in porn, trying to excite her even more.
“Mm.”
At the sound of Jin-hee’s moan in my ear, I got even more excited and moved harder. After a few thrusts, however, her hand came down and stopped mine.
Thinking she was just too turned on to keep up with me, the way women always were in porn, I pulled my hand out and lowered my mouth, beginning to lick and suck at her with my tongue.
Jin-hee accepted my tongue as it was, and I worked it diligently, but after a few minutes my mouth had gone numb and tingled.
At that point, I was once again amazed that my brother-in-law could supposedly keep sucking for an hour.
Once my mouth had gone numb too, I shifted beneath Jin-hee’s legs, preparing to penetrate her.
Then I hesitated, wondering if I should put on a condom, but Jin-hee seemed to read my mind and smiled.
“You can just go ahead. Didn’t your husband tell you?”
In that instant, I remembered hearing that she had also undergone a procedure for contraception, and I pushed myself straight into her slit.
“Ahh—”
I moved my hips with all the effort I could manage, but before long the urge to climax surged up all at once.
I couldn’t possibly finish there, so I held back and held back, but it was clear I wouldn’t last much longer. I withdrew and pulled away, thinking I needed to change positions naturally and calm the sensation of climax a little.
“Jin-hee, turn over for me…”
She rolled her body over just as I asked, offering her ass to me as she lay facedown in a rear-entry position, and I couldn’t stop myself from thrusting into her again.
It had been so long since I’d done it from behind that only a few motions were enough to send semen rushing up inside me. I could have come right there, but for some reason I felt like I shouldn’t, so I pulled out and sprayed my cum all over Jin-hee’s ass instead.
I must have been too excited, because the amount seemed greater than usual, and the pleasure I felt as I came was far more intense than any other time.
“Ugh!”
Before I knew it, I shouted and poured the rest of my semen over her ass, and when I was finally done, I collapsed in place and panted for breath.
Only after I had taken up the rear-entry position and finished my climax did Jin-hee finally look back at her own ass. She pulled tissue from the trash can beside the bed and wiped away my semen.
“Wow, you really shot a lot, Oppa. Is that how it usually is?”
“Haa… haa… no… not this much…”
Jin-hee wiped me clean with tissue, but apparently decided that tissue alone wouldn’t do, because she ran straight into the bathroom. A moment later, I heard running water.
Seated on the bed, I looked down at my now-shrunken cock and thought, So this is sex.
What I had wanted was sex like this with my wife, but the fact that I’d done it with Jin-hee, my wife’s own older sister, left me feeling strangely hollow.
While I was lost in that thought, Jin-hee came out of the bathroom, looking as though she had simply rinsed herself off with water and come right back out.
She walked over to me, grinned, and gave me a light push backward. Under her strength, I gently fell onto my back.
As soon as I was lying down, Jin-hee took my shrunken cock in her hand, lifted it to her mouth, and began sucking on it again.
Being sucked when I had only just finished made my strength drain away in fits and starts, and my mind grew so foggy it almost felt like this was what orgasm really was.
Just when I felt I couldn’t endure it any longer, Jin-hee pulled her mouth away and took another tissue from the side, spitting the saliva into it.
Watching that, I laid my head back on the bed and once again felt what I had felt earlier: so this is sex.
“Did you like it, Oppa?”
The way Jin-hee asked felt strange.
That was the kind of question men normally asked women, to see if they had been satisfied, but hearing it from Jin-hee made the whole dynamic feel inverted.
“Yeah. It was the best.”
“Then that’s good.”
I had never felt this before, but after sharing a body with her even once, Jin-hee looked beautiful to me.
“Oppa, but are you really going to be okay?”
“With what?”
“So-hee. You two are married. Even if you’re all into free sex now, it couldn’t have been easy from the beginning, right?”
“Hmm… what was it like? Honestly, I still don’t really know. The idea of So-hee being trained by your husband still doesn’t feel real to me. The video I saw earlier only had audio, so… it’s hard to picture.”
“So you still don’t have much sense of reality yet. Then let me start with us. We weren’t like this from the beginning either. I’d always been a little more open than most, sure, but I never, ever imagined I’d live this way.”
I had only ever heard from her brother-in-law and from Jin-hee herself that our marriage was based on free sex. I had never heard what had led them to that point, so what she was saying now made me intensely curious.
“Our honeymoon phase was basically the same as anyone else’s. We’d do it while eating, do it while watching TV, just suddenly get worked up and go at it. Back then, I loved having sex with Oppa so much. I honestly thought all men were like him. Ah… this might surprise you, but even though I’d dated a few men before, penetration was only ever with my husband. Anyway, I loved it so much. Then I got pregnant with Yoon-sung, and I started thinking that sex the way Oppa and I did it might be too much of a burden on the baby, so I avoided sleeping together. Of course, I took care of things in other ways, but even then Oppa was more fired up than he is now, so he really had a hard time…”
Listening to her, I couldn’t help wondering what kind of life her brother-in-law had lived. I even had the absurd thought that maybe he’d been a sex machine since childhood.
“But then one day, a married friend came over, and while we were chatting, the conversation turned to husbands and sex. She’d married someone quite a bit older than her. He’d been a perfectly respectable choice, with a stable job and a solid social standing anyone would recognize, so even though he was older, she went ahead and married him. He was family-oriented and all that, but she said she was dissatisfied with the sex. I’d watched a lot of porn since I was young, and I liked talking about dirty stuff, so I used to talk like that with my friends a lot. Maybe that’s why she told me about it so sadly. At the time, I just laughed and bragged a little, saying my husband was too much for me to handle. She looked at me with this really envious expression.”
“That friend was the one you were talking about?”
“That’s right. So I joked that my husband had been having a hard time lately because I was pregnant, and asked if she wanted to help him out a little. But… I guess it must have really been rough for her, because she kept asking me if that was really okay. In the end she called her husband and said she was staying over at our place. I was kind of bewildered too, but then I remembered how hard my husband had been taking it, and I rationalized it by thinking, Well, if I can’t do it for him, maybe it’d be good if he could at least release some of that pressure. That evening, while we were drinking together, I casually told Oppa. I explained the situation in broad strokes and said if he wanted to, he could go ahead—I really meant it, I honestly did. Up until that point, I truly was fine. I just wanted to ease his sexual frustration. But when I actually heard my friend moaning, I got angry.”
“Ah… so then what?”
“Still, what could I do? I was the one who told him to do it. The next day, my friend went home without knowing anything I was feeling, thanking me all the while, and I got so irritated seeing my husband sleeping after using up so much strength for the first time in ages. So I started hitting him to wake him up. Oppa got up, totally dazed, and took all my anger without a word. If I hit him, he’d just take it. If I cursed at him, he’d just listen. After a while, I got tired too, and I felt sorry for him… I was the one who told him to do it, and then I hit him and cursed at him without warning… But the weird thing about people’s hearts is that if you just let it go like that, it starts feeling as if I’m the one losing out. So I told him too: once I had the baby, I’d sleep with other men as well. Oppa just laughed and said I could do whatever I wanted. For now, he told me to calm down and just take care of me and the baby in my belly.”
Her brother-in-law had always struck me as a gentle bear of a man, but he had a big frame and an aura that made it clear no one should try to pick a fight with him casually.
I had never once heard him raise his voice or swear. His voice itself was low and deep, but he always spoke so softly that I could easily imagine how he must have said those things to Jin-hee.
“Time passed again after that, and Yoon-sung was born, so everything got hectic. Even after that, until Yoon-sung turned one, I didn’t sleep with Oppa at all. I was too busy raising a child, and Oppa never showed any sign of being frustrated, so I forgot all about it too. After Yoon-sung’s first birthday, things finally got a little easier, and I slept with Oppa again for the first time in ages. It felt just as good as before. But then I remembered what I’d said back then. I asked Oppa what he’d think if I really slept with another man, and he said, completely casually, that if I wanted to, I could. He’d always be by my side. I think I was being stubborn then. I wondered if he could really hold me after I’d slept with another man and still act like nothing happened, so I asked him if he had any friends around.”
By the time I had heard this much, it was only natural that I was thinking she wasn’t normal either.
