Kill Your X Chapter 12

“Ha, if you’re going to flatter me, at least make your expression match.”

“I’ll try.”

As if he didn’t have the same thing dangling between his own legs. Si Yeonho admired my cock for a while before slowly raising his hand. I firmly grasped his wrist, and he looked up at me with that usual indifferent expression.

“A blowjob is done with the mouth.”

“Ah.”

Watching him silently lower his hand, a good idea suddenly came to mind. I excused myself and returned from the dressing room with a tie.

“Yeonho, would you mind putting your hands behind your back?”

I tied his thick-wristed hands together with the tie. Returning to my position, I was quite pleased with the sight that greeted me. Si Yeonho, kneeling obediently with his hands bound, was arousing to a degree that made me question my usual preferences.

“It suits you.”

“Shall I suck it now?”

It was even better that he didn’t ask questions like why I was suddenly tying his wrists. I hadn’t expected his way of speaking, which I initially found rude, to be so effective in this situation.

“Yeah.”

“Since it’s my first time, I’m not sure I’ll be good at it.”

“What am I going to do? I’m not in the mood to go easy on anyone today, even a first-timer.”

My body grew hotter with each passing second. I wanted to see his currently unexcited face flush with arousal and become a mess. I caressed his jawline, and Si Yeonho buried his face in my hand. His actions were cute, but his low, gravelly voice was sensual.

“Then teach me well, Sunbae.”

‘Sunbae.’

His last word echoed in my ears, and a sudden pang in my chest blurred my vision. My mind rapidly regressed to ten years ago, to my high school days in uniform. A blurry, noise-filled scene played briefly.

I was hiding something in a corner of the high school library. I thought no one else was there at that time, but my eyes met Si Yeonho’s, and an unexpected incident occurred.

How did Si Yeonho look at me back then?

A boy whose school uniform pants were a bit short because he’d grown so quickly. You, who only reacted after a long pause when I called your name after seeing your name tag. You definitely… back then…

“Ugh!”

The sensation jolted me back to reality, scattering my thoughts. Si Yeonho had taken my half-erect cock into his mouth.

From the start, he sucked hard, his cheeks hollowing. He swallowed deeply, almost to the point where my cock touched his throat, in a near-vacuum state. I was quite taken aback by his skipping the exploratory phase. I naturally expected him to hesitate since it was his first time, but Si Yeonho seemed completely unfazed by the lewd act.

‘What the hell? This is his first time giving a blowjob?’

His technique was far from amateur; he teased the sensitive ridge of my glans with the tip of his tongue before gently licking the shaft. His near-perfect control of pace quickly brought me close to orgasm again. If this truly was his first time, Si Yeonho should seriously consider a career change.

“Ha, wait. Wait a minute.”

Si Yeonho immediately stopped at my words.

“Don’t take it all the way out. Yeah, like that…”

The feeling of his warm, wet mucous membrane enveloping my cock was incredibly pleasurable. The teasing flicks of his tongue across the surface resumed as soon as I seemed to have calmed down. He swallowed me whole again. The unfamiliarly intense tightness made me grip his hair.

“Hngh, ah, ah…!”

Si Yeonho continued moving his head back and forth, unfazed. Shit, I was really going to cum.

It felt good, but also bad. He was clearly in my control, I was the one who made him do this, yet it felt like I was the one being controlled.

A perverse impulse led me to thrust my foot between his knees. Si Yeonho stopped sucking when I firmly pressed down on his groin. The slight furrow of his brows sent a surge of mental pleasure through me.

“Who told you to stop?”

As I put more weight on my foot, I could feel Si Yeonho hardening in real time beneath his pants. He acted as if he had no emotions or desires, but in the end, he was just like me. Someone who gets hard when stimulated and wets his pants when excited.

I continued receiving the blowjob while occasionally stroking his cock with my foot. He could have complained that his jaw hurt or that he was out of breath, but Si Yeonho persevered without any sign of gagging, even at that depth. He even licked up the precum that leaked from the tip.

“Ah, good. Ugh, mm…”

Honestly, my pride was hurt. I’d had so much sex in my life, but this was the first time I’d felt this way from just a blowjob.

As I reached the edge of orgasm, I abruptly pulled my lower body back. My fully erect cock sprang from his mouth. Spraying my semen on Si Yeonho’s face was entirely intentional.

“Wow.”

Si Yeonho took my abuse with his eyes closed. The milky-white fluid messily coated his face. The semen dripped down his high, straight nose. His perfectly balanced lips were slightly reddened from sucking my penis moments ago. It was a breathtaking sight.

“Yeonho, what am I going to do with you.”

I knew it was polite to wipe it off immediately, but his docile attitude made me want to continue being mean. I touched his chin with my finger, and his face followed effortlessly.

“I might end up liking you more than I thought.”

As he started to open his eyes, I quickly grabbed a tissue. Si Yeonho silently accepted my ministrations. I almost regretted wiping away the semen that clung to his long eyelashes like dew.

Once his face was clean, Si Yeonho returned to his composed appearance, just like when he first entered my home. If I hadn’t touched his cock with my foot, I would have believed he was genuinely asexual.

“Did you like it?”

He asked, turning his head from side to side to loosen his neck.

“It wasn’t bad. But are you really sure it’s your first time? No matter how I think about it, it doesn’t seem like it.”

It wasn’t just “not bad.” I wanted to lock him up in my house and make him give me blowjobs morning and night. I hid my dirty thoughts and pulled up my pants. Si Yeonho was so composed that I felt awkward about being the only one panting.

“That’s good to hear. Please teach me in more detail next time.”

“Teach you what?”

“Things like how to please you more. I just did it randomly, but it felt so good, I still don’t know.”

Just like at the cafe the other day, he definitely seemed to have a foot fetish for stepping on other men’s dicks. Right?

His unnecessarily serious analysis left me speechless. I had been in the best mood just moments ago, but his mood-killing remark chased away any remaining excitement.

“You were annoyed just now, weren’t you? That I called you late at night and made you do this.”

“No, I wasn’t.”

“Be honest. There must have been other people besides me who pointed out your shitty way of talking.”

“There have been many.”

Despite that, judging by the way he still talked, he didn’t seem to have any intention of changing. Objectively, it was annoying, but for some reason, I found it rather cute, making me wonder if I’d gone crazy. My judgment was blinded by lust. A couple more good blowjobs and I’d be ready to move in with him.

As I agonized over my skewed judgment, Si Yeonho started to fidget. He was still kneeling in front of me.

“Oh, right. I’ll untie you.”

Right after I lifted myself off the bed, there was a small ‘thud,’ and Si Yeonho, like a magician, spread his arms out in front of me. The silk tie lay on the floor.

“If restraint is really your goal, you shouldn’t tie it so loosely.”

“Huh?”

He offered advice after freeing himself. I didn’t think I had tied it that loosely. I momentarily wondered if my memory was distorted by arousal. He picked up the tie, handed it to me, and added,

“I’m telling you this in case you get sad if it comes loose mid-way next time.”

“What? I wouldn’t be sad over something like that.”

I had tied his wrists, but I didn’t particularly have an SM kink. Of course, sometimes I craved rough, animalistic sex, but finding a partner who could match that kind of intensity was even more difficult.

“I’m glad to hear that.”

Si Yeonho stood up and straightened his clothes. Feeling like I hadn’t treated my late-night guest very well, I followed him to the kitchen and asked a belated question.

“Yeonho, do you want something to drink? I have water and juice.”

“Water.”

I filled a glass and handed it to him, and he slowly drank the water. The sight of his bobbing Adam’s apple was so alluring that I stared, mesmerized. It suddenly felt strange that he was in my space. Even when I met partners, we usually messed around at clubs or hotels; it was rare for me to bring someone home.

“Are you feeling better? You seemed upset earlier.”

Si Yeonho quietly set down the glass. I felt a little embarrassed that he had noticed my bad mood.

“Not really.”

Si Yeonho’s only response to my obvious lie was to blink a couple of times. I suddenly became curious. We only had oral sex today, but would he still be so calm after a whole night of tumbling in bed? Somehow, I couldn’t picture Si Yeonho panting with excitement.

“Sunbae.”

“What?”

“You’re not going to let me sleep over, are you?”

I followed his gaze to the wall clock. The hour hand had just passed one in the morning.

“It’s not that I don’t want you to, but I don’t usually let other people sleep over. I’m a very light sleeper.”

“I understand. I’ll be going then.”

As soon as he received his coat back, Si Yeonho headed for the front door without hesitation. I mindlessly followed him and then clapped my hands together.

“I almost forgot. Yeonho, take your money.”

I brought out the bag of money that I had stashed away like stolen goods in the corner of my room. Si Yeonho stared blankly at the black bag before turning around.

“Did you bring your car? I’ll help you carry it.”

“I’ve thought about it.”

He continued, tilting his head slightly.

“Giving something and then taking it back doesn’t feel right. Whether it’s money or life.”

“What?”

“Goodnight, Sunbae.”

Si Yeonho left the house empty-handed. The slam of the front door echoed unusually loudly.
