Eun-won gripped Cha Se-jin’s hand, which was draped over his face, with both of his own. He knew exactly what fluid had soaked that hand, but it didn’t matter. His body and mind were too hot, his breath kept coming in short gasps, and the inside of his body—where Cha Se-jin’s fingers had been—felt so itchy that it was unbearable.
“…More, hng, please do it more….”
“…….”
“My body, my body feels so strange… hng….”
Did he even know what he was saying right now? If he could, Cha Se-jin wanted to write down everything Eun-won was saying and read it back to him once he regained his senses, just to see him blush, but he didn’t have the luxury. Cha Se-jin slid his tongue back into Eun-won’s mouth, which tasted as sweet as his pheromones, while using one hand to undo his belt buckle and lower his zipper.
As he pushed down his pants and underwear halfway, his trapped member sprang out threateningly. He had never been this aroused before. He felt that a single release wouldn’t be enough to solve this. Gripping his fully erect member, Cha Se-jin pressed the glans, drenched in pre-cum, against the space between Eun-won’s legs.
The hard glans pressed against the perineum, which was slippery with arousal. As he rubbed the plump area while holding the tip of his member, Eun-won groaned. Cha Se-jin swallowed the muffled groan along with the saliva, rubbing his tongue against it, and smiled with a slight crinkle of his nose as he slid the glans along.
“Tell me if it hurts. If I don’t listen even after you tell me, go ahead and poke my eyes or slap my cheek. You can even bite me somewhere.”
“Hng, ah…. Ah…….”
“Darling, this is fucking important. Are you so focused on eating this cock that you can’t even hear me?”
Cha Se-jin pressed the glans against the twitching hole as if to push inside, then pulled back again, causing Eun-won’s hips to lift. Cha Se-jin laughed at the way Eun-won’s hips instinctively followed his cock, begging for it to be inserted without even knowing why, and licked the tip of Eun-won’s tongue. The way they rubbed the tips of their tongues together with eyes closed was erotic. Erotic enough that he could have come several times just by doing that.
As he pressed and rubbed the glans over the hole, which was making squelching sounds, Eun-won gasped, losing his grip on his tongue. The pheromones were too strong; he had no way to endure it any longer. Cha Se-jin let the thin thread of reason he had been holding onto snap. At that moment, the smooth, thick glans parted the damp hole and was sucked into Eun-won’s humid, hot interior.
“Haa-ah…!”
Since he had already cleared the way with his fingers and the inside was so wet, the member slid in without resistance. Of course, it was incomparably larger, thicker, and longer than a finger, so it couldn’t go all the way in at once, but it plunged straight to the spot where the fingers had felt good and struck it.
At a stimulation far greater than when three fingers had been thrust and flicked, Eun-won’s toes curled tightly and then relaxed. His head tilted back, and a sobbing groan escaped his parted lips. Thinning semen leaked out again from the tip of his member.
“Did you come… whew… before I even put it all in?”
Eun-won gasped, unable to even draw breath at the heavy presence of the member filling his gut. It was different from when the fingers went in and out. He wondered if it was okay for something this large, this overwhelming, to be inside his body, yet he loved how the itchiness deep inside stopped the moment Cha Se-jin entered.
“Relax… ah, relax a little. It’s too tight….”
The interior, already narrow, tightened further due to a mix of emotions. The hot, narrow walls clung to the member without a single gap. Cha Se-jin groaned low, frowning, and lowered his head. As his face descended, Eun-won’s lips parted first, as if he knew a kiss was coming. It was a face that made all the teaching worth it. See? I told you he was fucking erotic.
He rolled his tongue to help Eun-won relax his body and gently massaged his hips. Soon, he felt a slight release of tension. Cha Se-jin didn’t miss the opportunity; he pulled his hips back and then drove deep inside with a heavy thud.
Because of the squelching arousal, an erotic sound echoed as the member went deeper. Surprised by the member piercing a spot even deeper than he had imagined, Eun-won broke into tears and shuddered.
“Ah, hng, ng…!”
“Do you like it here?”
Eun-won wouldn’t know, but although it had gone in a bit further than before, the member still hadn’t reached the root. However, Cha Se-jin decided to be satisfied with this for the first time. If he went any deeper, Eun-won might move past surprise and become terrified. There was no benefit to feeling fear during the first experience. Based on that memory, he would be scared before the second time even began.
Instead, watching Eun-won cry and feel pleasure, he repeatedly poked the sensitive spots with the glans. Without pulling his hips out far, he flicked them in short bursts, hitting the same spot, and an erotic groan rang out with every strike. Seeing this beautiful boy grip his hand on his waist and cry while feeling pleasure made him feel like there was nothing else in the world. This moment was so satisfying that he wouldn’t trade it for anything.
“…Haa…! Nng, ah, there… ng, too….”
“Yeah, it feels too good, right?”
Every time he put more strength into pounding the inside, the inner walls wrapped around the member without a gap. He loved rubbing those walls as he pulled back and then stretching those tight walls as he pushed back in; he moved relentlessly, holding the small body and crushing the deep interior.
“Ah, ah…. Ng, ah…! Aah…!”
The white waist held by both hands twisted. It seemed like he wanted to escape, so Cha Se-jin gripped him tighter to prevent it and thrust up persistently. Eun-won’s groans grew louder, and his head tilted back once more. Semen, even thinner than before, burst out again, soaking his chest, stomach, and this time, even his face.
“Ng…. Ah….”
As Eun-won ejaculated, his lower body tightened sharply. A violent sense of release surged through the member that had been stirring the soft, narrow interior for so long. Holding Eun-won’s pelvis and burying his member deep inside, Cha Se-jin poured out the semen he had been holding back. Eun-won twisted his waist softly at the feeling of a large amount of semen being shot powerfully into his gut. Exhaling a satisfied breath, Cha Se-jin tilted his head down and completely engulfed his lips.
Eun-won let out a whimpering sound in his throat and stuck out his tongue. Cha Se-jin’s tongue warmed the already hot interior of his mouth. It was a strange expression, but it was true. Eun-won loved the tongue that felt warm even amidst the heat, and he relied on that warmth for everything.
After pouring out relentlessly, he finally regained some clarity. He wasn’t completely lucid, but he could recall where he was, who he was entwined with, and what he had been doing with Cha Se-jin.
“Why, are you tired?”
Cha Se-jin sucked on Eun-won’s small tongue, pulled away, brushed his hair back carelessly, and lowered his head to his chest. He took the nipples—which he had mostly just rolled with his fingers earlier—between his lips, playing with them and gently rolling them with the tip of his tongue to stimulate Eun-won’s pleasure again. Eun-won, appearing drained, nodded slightly with a flushed face.
“Do you want to sleep?”
This time, he shook his head obediently. He felt exhausted, but he wasn’t sleepy. He had merely described his current state, yet he could feel the member still inside him growing larger again. Eun-won’s eyes widened at the sensation. With an aroused expression, Cha Se-jin grabbed Eun-won’s slender calves and hoisted both over his shoulders.
His hips and waist, which had been pressed against the bed, lifted, exposing the hole that was gripping Cha Se-jin’s member. Eun-won closed his eyes in surprise upon seeing Cha Se-jin’s thing inside his own body.
“Does seeing yourself eat a cock suddenly make you shy?”
Cha Se-jin laughed aloud and moved, gently stirring inside Eun-won. A wet, slapping sound echoed every time he thrust, as arousal and semen mixed together.
“You’re tired, but if you don’t hate it, what should we do? Should we keep having sex?”
“Haa-ah…!”
This time, his head snapped back. His senses were quickly revived by Cha Se-jin’s rapid hip movements. Feeling strength returning to the member that had ejaculated an unknown number of times, his body shook in sync with Cha Se-jin’s movements. Looking down at him, Cha Se-jin licked Eun-won’s calves draped over his shoulders.
Thud. The member went deeper, rapidly striking only the spots where the glans felt the most pleasure, when a vibration rang out from somewhere. While continuing to move his hips, Cha Se-jin turned his head, pulled his discarded pants from the bed, and took out his phone. He smiled at the two words ‘Mom’ appearing on the screen.
“It’s Mom. What should I do? I think I have to answer.”
When he showed the phone screen to Eun-won, Eun-won shook his head. Cha Se-jin laughed, shook his head back, and touched the call button. Eun-won’s breath hitched.
“Yes, Mom.”
Yes, Se-jin. Are you home? I just got back too, and Butler Yoon said you seemed to have arrived.
His mother’s always-composed voice came through the phone. Cha Se-jin kept his gaze fixed on Eun-won’s face, which was trembling as he tried to stifle his sounds, and crushed the deep interior with loud, thumping sounds.
“Yeah, I got back a little… while ago. Eun-won isn’t feeling very well, so I brought him in.”
Eun-won? How is he unwell? Should he go to the hospital?
“No, it’s not that bad…. I think his cycle suddenly started, so if he just rests with me for a few days, he’ll be fine. Don’t worry.”
That can happen suddenly when tension releases after a big event. Take good care of him. Should I bring some food?
“If we need anything, I’ll call Butler Yoon. Until then, please tell everyone not to come to the annex.”
Cha Se-jin, who had been gently rubbing Eun-won’s interior with his member, wondered if he was being too mischievous; he stopped moving and stroked Eun-won’s cheek. He understood that Eun-won might be annoyed since he had put him in a difficult position—no, he felt Eun-won should show it—but the eyes looking up at him were merely docile. Instantly judged one hundred percent guilty, Cha Se-jin groaned. He wondered what on earth he was doing to this sweet boy.
“Yes, I’ll do that.”
He answered his mother’s few more requests and ended the call. After confirming the call had completely disconnected, he tossed the phone aside and lifted Eun-won up to sit on top of him.
“Why are you being so good? If you hate it, you should at least slap me.”
Cha Se-jin took Eun-won’s hand, opened his palm, and pressed it against his own cheek. He pulled it away slightly and then applied a bit of force as if slapping, creating a small smack sound, though it didn’t hurt. Startled by the sound, Eun-won quickly curled his fingers.
“……I didn’t… feel like I hated it….”
Wait, maybe I’m innocent?
