Sex, Sex, Sex!
Subin's fingertips began gently rubbing Chaerin's small nipples.
For ordinary foreplay it was a surprisingly refined motion, the kind of touch that made me picture just how many lonely nights she must have spent teasing her own nipples alone.
"Nngh, ah, ahh…! Right there, hngh…!"
Chaerin couldn't hold back; pure, heated moans spilled from her lips. No anger, no irritation—nothing but the raw cry of pleasure. Just hearing it made my cock even harder, as if someone had poured aphrodisiac straight down my throat.
I kept her locked in the full nelson and drove into her scorching pussy without pause. Subin joined in, flicking her tongue over Chaerin's clit with relentless focus while her fingers kept tormenting those nipples. The twin waves of sensation we poured into her left Chaerin completely powerless. She became nothing more than an orgasm machine, helplessly climaxing again and again.
I hadn't set out to torment her on purpose. Watching her hang limp and bounce under me had simply been too erotic; a mischievous urge had taken over. And even while her mouth begged Subin to stop, Chaerin never truly tried to push my cock out of her. Like Haram, her body was honest. It wanted this excess of pleasure.
Chaerin wasn't special—most women in this world would react the same way. Men so rarely gave them pleasure that their bodies stayed hypersensitive; a kiss alone could light them up. The idea of a man "raping" anyone here was almost a joke.
—Slap, slap, slap!
I thought that while I kept thrusting, and Chaerin's slender frame finally couldn't take any more.
"Ah, uh, heugh…"
—Sploosh…
Hot liquid—piss or squirt, I couldn't tell—ran down her thighs. Coming that hard while getting fucked was pure female perfection. Her eyes rolled back toward the ceiling; the extreme pleasure had knocked her out cold. Once she fainted, the grip of her pussy eased a little. I could have kept pounding her for fun, but I didn't want her swollen and sore, so I stopped.
—Pop!
I pulled out of her limp body. A thick, lewd scent rose from her soaked pussy. And as if it were the most natural thing in the world, Subin—who had just been licking and sucking Chaerin's clit—took my cock into her mouth. She stretched her small lips as wide as they would go and worked her tongue hard, determined to clean every last drop. Truly devoted cleanup fellatio.
I enjoyed the blowjob while laying the unconscious Chaerin gently on the bed, then asked Subin,
"Subin, how do you want it? Doggy? Cowgirl? Mating press? Or full nelson like Chaerin?"
Chaerin needed a rest, so from here on Subin would have me all to herself.
"Chup, slurp, shlick… I want cowgirl. Haah, mmph…"
She blushed while naming the position. Asking for what she wanted still embarrassed her a little, yet her mouth never stopped working my cock. Face and voice were pure innocent virgin; tongue and throat were pure expert.
Once my cock was reasonably clean I lay back on the bed and gestured for her to climb on. She didn't refuse; she hurried into place. My size made vigorous movement hard at first, but she soon began rocking her hips. She must have practiced—her form wasn't bad at all.
"Ah, hngh, ahh, I'll… I'll try my best…! Nngh…!"
Breathing hard, Subin shook her hips for all she was worth. Riding me, she rolled her ass forward and back with real skill. The simple motion alone was plenty of stimulation, and every so often she clenched her pussy tightly around me, which felt even better. Because she reacted less dramatically than other women when I hit her G-spot or the mouth of her womb, I could enjoy the cowgirl ride longer than usual.
She watched my face and the way my cock twitched, constantly adjusting the angle to find what I liked best. I wanted to praise that earnest effort, so instead of words I reached up and kneaded her soft breasts freely, rewarding her with my hands.
Today's threesome had been even better than expected. Considering it was Chaerin and Subin's first time sharing me, I couldn't wait to see how bold and filthy they would become next time. Eventually the two of them would work together like a raid party coordinating to take down a boss, satisfying my cock as a team. Just imagining it made my lower belly feel heavier.
"Hey, hold still already!"
Chaerin was scrubbing my armpits with soapy hands when I flinched; she smacked my back with her palm. There was no real force behind it—more of a playful pout than a real slap.
After that thoroughly satisfying round of sex, all three of us were crowded into Subin's bathroom. More precisely, I was showering while Chaerin and Subin washed every inch of me, waiting on me hand and foot.
"Can't help it if it tickles. You two can't stand being tickled either. Right, Subin?"
"Mmph, mmph? Pwah… Yeah, I can't handle tickling either. Hehe."
Subin answered with a shy little laugh. She had been kneeling on the tiled floor helping wash me; at some point she had simply taken my already-hard cock into her mouth and started sucking. Chaerin had wanted to do the blowjob herself, but unfortunately she had lost the rock-paper-scissors match against Subin for the privilege.
Warm water cascading down my back while a hot mouth enveloped my cock felt like pure heaven.
"…I want to suck you too."
Having finished my back, Chaerin muttered the complaint while staring at Subin. I didn't miss it.
"You lost the game."
"Even so…"
"All right, all right."
I laughed, grabbed her wet hair, and pulled her into a kiss.
"Mm, mmph, nngh♡"
The grumpy expression vanished at once; she melted into the kiss with pure happiness, tongue soft and obedient. While we kissed I slipped a finger against her pussy. Even after all those orgasms earlier, she still wasn't dry. Just lightly stroking the mound made her slick again.
I ended the kiss with Chaerin and grinned at Subin.
"Stick your ass out for me."
Subin happily turned her back and presented her hips. I didn't need to look to know her pussy was already wet and waiting. Chaerin's face fell again; losing that rock-paper-scissors match still stung. So I smirked and told her,
"Go get your revenge from earlier."
Subin didn't hear the words; she was too busy getting into doggy-style position, trembling with excitement. I lined up my ready cock and buried it in her from behind in one thrust.
—Schlick…
"Nngh… Even after coming so much you're still rock-hard♡"
Subin clenched around me joyfully. I started a steady rhythm; her face flushed and her breathing turned ragged.

Just then Chaerin stepped in front of Subin so they faced each other. Before Subin could say a word, Chaerin kissed her hard.
"Mmph? Wait, chup, shlick, why so sudde—ahh?!"
At the same time Chaerin's hand reached down and began rubbing Subin's clit while my cock was still pounding into her. Chaerin kept kissing her with smiling eyes. Caught between the cock from behind and the fingers on her clit, Subin twisted and writhed, not knowing what to do. She didn't climax instantly the way other girls did, but the tension in her waist told me her orgasm was rushing closer fast.
Chaerin worked diligently—kissing, stroking that clit—exacting her earlier revenge. Halfway through, Subin started a timid counterattack of her own: she groped Chaerin's breasts. The funny part was that Chaerin was so much more sensitive; she was getting as much pleasure from the breast play alone as Subin was getting from actual sex. A truly unfair difference in erogenous zones. In a contest like this, almost no woman could beat an HSDD girl like Subin.
Watching the two of them cutely caress each other, I smiled in pure satisfaction. This was exactly why a man built a harem.
I slammed my hips harder.
I fucked Subin thoroughly right there in the shower. When we finished with her, I gave Chaerin the exact same treatment. And of course, when it was Chaerin's turn, Subin returned the favor by rubbing her clit. Chaerin squirted repeatedly, spraying love juice everywhere, yet never once let go of the cock buried inside her.
The hot shower sex went on and on, long after night had deepened around us.
A very long time.
