The Scent of Soap and Secrets
"Oppa, it’s embarrassing when you stare so intently." Yerim laughed, pulling the towel she’d been wrapped in down to her hips. The sheer destructive power of that sight... While I was busy ogling her breasts, she began washing her face with foam cleanser, revealing her fresh, delicate bare skin. Even from behind, I could see the curve of her side-boob; she really was incredibly well-endowed.
"I’m coming in," she said, hanging up her towel. She stepped between my legs as I sat, turning her back to me. Her skin was smooth, without a single blemish, and her glutes were sculpted—a testament to her dedication to exercise. Her nape was so slender it made me want to nip at it. Come to think of it, I’d never really looked at her body this leisurely before.
I hugged her from behind and kissed her nape, making her giggle as if ticklish. Behind her ears, her shoulders, her neck—I planted light kisses everywhere, and my heart began to race. It was the first time I’d ever held her this calmly.
"Kissing my neck feels nice, too," she murmured. She turned around and took the lead, pressing me back against the tub. She kissed my forehead, my cheeks, my neck, and under my eyes... as if she were trying to stamp her mark all over my face, making soft, smacking sounds with her tender lips.
But after the kiss, Yerim’s expression turned deeply troubled.
"Kangmin-oppa, you’re mine, right? You won’t cheat on me with Yeongseon-unnie, will you?"
Charles deduced this based on Yeongseon’s tastes and the morning’s events she’d read while kissing him. *Yeongseon-unnie is dangerous. She might actually ask Kangmin-oppa to date her.*
Kangmin clearly liked Yerim. But Charles knew all too well that she couldn’t truly *be* Yerim. If he were dating the real Yerim, he wouldn’t even glance at Yeongseon. But I’m just a substitute. That thought pierced Charles’s heart. If he were dating the real Yerim, he would never have revealed his minor kinks, like anal sex. *I’m a succubus, so it’s fine, right?* That was the mindset he used to justify probing both of Charles’s orifices, pinching her nipples while she performed oral, and berating her as a "slut."
'But I have nothing but my body to hold onto Kangmin-oppa...' Charles bit her lip. Just because she was a succubus didn’t mean she didn’t know love. But she was a stray comet, a lost wanderer. A wretch with no home, no roots. Always the weaker one who had to yield. She had to beg for a contract, strip when he told her to, and leave the human realm if he commanded it. That was why the fact that Yeongseon wanted Kangmin made her even more anxious. If Kangmin actually started dating Yeongseon—or even if they just stayed sex partners and he grew fond of her—and he cast her aside...
She asked, feigning a brighter tone, "You won’t sleep with Yeongseon-unnie, right?"
But Kangmin seemed to take it as a joke. "Oh, well... I’m not sure... If that happens, can’t I just be good to both of you? Besides, I’m already having sex with you, Yerim, every day."
Kangmin answered with a laugh, thinking it a lighthearted question. But Charles swallowed the trembling anxiety in her chest. She replied, pretending to be at peace.
"What kind of cheating-boyfriend talk is that? I do everything for you, just like Yerim does, and I even show up in your dreams as Yeongseon-unnie. I do anal, I do rimming—everything! Isn't that too much? Besides, tonight, Yeongseon-unnie will do whatever you want in your dream. You’re so mean, Oppa!"
"Hey, I know you’re good to me, Yerim." He was still carefree.
Yerim opened her mouth. *Oppa... can’t you write in the contract that you won’t sleep with other women without my permission?* She almost said it, but swallowed the words. If she bound him with a forced treaty, he would surely lose interest. Charles forced a smile.
"No, it’s okay! Sigh. I’ll understand everything! Alright. But you can’t neglect me, okay?"
Charles was always the one who had to yield.
"Ah, of course. And what are the chances I’d actually sleep with Yeongseon-noona?"
It’s probably a 99% chance. I have to at least delay it as much as possible. Charles hugged Kangmin, hiding her teary face. The warm water rippled, and she could hear the thumping of his heart. She rested her head on his chest and listened. The thumping grew louder and louder. He was nervous because Yerim was pressed against him, making his pulse race.
Thump. Thump. Thump. His heart beat like a drum. His body was honest. Charles chuckled.
"Kangmin-oppa, do you get nervous when you’re with me?"
"Of course. How could I not?"
Charles tightened her embrace. Kangmin carefully placed his hand on her back and stroked it. After a long while, Charles spoke up.
"Oppa, do you love me?"
"Of... of course I do."
Charles looked up at Kangmin’s face. He was blushing a deep red, looking restless. Courage slowly welled up in Charles’s heart. *That’s right, he says he loves me. His face is so red, too. But this isn’t enough! I’ll make him so addicted that he can’t live without me.*
"Oppa, do you want to stand up?"
Charles shook off her troubled heart and smiled. *I’ll leave the future to my future self! For now, I’ll enjoy life in the human realm and do my best! He’s already so excited right now. I won’t worry! I am Charles, the sister of the proud Charsilla and the daughter of Michir! Oppa will eventually fall for me, too!*
Charles decided to do for Kangmin the things she’d only learned in dreams and had been too shy to try. *Men like lewd things anyway, right?*
"The soap here smells really good," Yerim said, squeezing out a generous amount of body wash and working up a thick lather. *Wait? There’s a shower towel.* But after making me turn around, she used her hands to meticulously wash me, starting from my thighs. Slowly, the object in my groin began to rise.
"Bend your waist a little, Oppa." I obediently complied. Behind me, Yerim stuck out her tongue with an "Ah." She squeezed a bit of body wash onto her tongue and brought her face to my buttocks.
"I’ll make you nice and clean." She mumbled, careful not to let the soap fall from her tongue, and then she stood her tongue up and invaded my rear. Her tongue scrubbed the inside of my buttocks clean, while her hands, slick with lather, slid over my testicles and the length of my shaft. I’d never been attacked from both sides like this before. It was a dizzying pleasure. The body wash acted as a lubricant, allowing her tongue to move smoothly inside me. I felt my legs go weak and had to lean against the bathroom wall.
"Does it feel good?" she mumbled with her tongue buried in my rear, her tongue moving in complex patterns. My cock stood even stiffer. Her tongue writhed as it cleaned me, and her hands softly stroked the back of my scrotum. Her left fingertips gripped my glans, squeezing and releasing, driving me wild. It felt like I was in heaven.
Yerim’s devoted deep-kissing never faltered. Breathing through her nose, she sucked on my anus as if it were the greatest joy of her life. Anus, scrotum, glans... being attacked in all three spots at once left my head spinning.
Slurp, slurp. The mixture of foam and saliva made lewd sounds. My mind was hazy. It felt like being wrapped in a soft silk blanket. As my three erogenous zones were stimulated, the urge to ejaculate surged.
"Yerim, I think I’m going to come."
At that, Yerim placed my scrotum in her hand and rolled it gently, as if gauging when I would climax. My scrotum, feeling her licking touch, trembled violently. *Oh, it’s coming—*
Just before I ejaculated, Yerim moved from my rear to my front. She pulled my surging, foam-covered cock toward her mouth, adjusting the height. She took my cock into the mouth that had been serving my rear just moments before. The inside of her mouth, slick with body wash, felt like it was melting my cock away.
Splurt, splurrrrt— Thick semen erupted from my cock. It was incomparable to when I’d cum in her mouth in the bathroom yesterday. Even after I finished, Yerim’s hand, still clutching my testicles, moved rhythmically. Every time she squeezed gently, the remaining semen was pushed out through my urethra. Yerim squeezed out the last of it, swallowing every drop into her throat, mixed with the leftover body wash.
"Haa... haa... you didn’t have to swallow that much..."
"I just want to do everything for you, Oppa..."
Yerim smiled with a mouth that wouldn’t quite close after the long service. She had an expression like an *ahegao*. Her eyes were red from lack of air, her mouth agape. There was body wash clinging to the corners of her lips, looking like semen foam. It was an expression that suggested she would have made me erect again immediately if I hadn’t just cum so much.
After rinsing her mouth, Yerim snuggled up to me. The bathtub was warm, making me feel drowsy. Especially after the intense, dual-sided stimulation I’d just experienced.
"Where did you learn to do that?"
"...I only heard about it from my sister. This is the first time I’ve actually done it. How was it...? Did it really feel good?"
Kangmin nodded, but he still looked skeptical. *Did Charles learn this? Hmm... She said she’d never done it with a man, but is that true?* Charles blushed with indignation. *I was in a brothel in the Demon Realm, but I’ve never actually slept with a man!! It was all in my dreams!* She could tell what he was thinking just by looking at his face.
"I really did it for the first time!!! I did it even though I was embarrassed! Forget it!!" *It’s useless to try so hard to please him!*
Kangmin scrambled to stop Charles as she tried to leave. *I’m not saying I don’t believe you! I didn’t say anything!* But it took a long time to soothe the sulking Yerim. In the end, they only managed to leave the bathroom when they were on the verge of being boiled alive in the hot water.
