“Ah, ugh… hng….”
He had prepared himself for the fact that it wouldn’t be easy, but a dull pain beyond his imagination surged through him. Every time the fully erect member pushed inside, Yoo Jiha’s jaw trembled and tilted back. Fearing that a scream telling him to stop would burst out at any moment, Jiha clenched his teeth. The fingertips gripping Jeil Heon’s forearm turned white, and a grinding sound echoed between his tightly shut teeth.
He barely managed to open his eyes to see how far it had entered, but Jeil Heon’s hips had barely moved. A sudden flash of fear struck him—wondering if he was truly about to be torn apart or if something would go wrong.
Looking down at Yoo Jiha, who had turned pale from the pain, Jeil Heon exhaled and straightened his waist. Jiha gripped his forearm even tighter, trying to prevent him from pulling out.
“I’m sorry for forcing it because of my own greed, Jiha.”
“Ugh, don’t… don’t pull it out.”
“How can I keep going when you’re in pain?”
“I… I like, hng, the pain. Masoch… that, masochis….”
He held onto him desperately, not even knowing what words were coming out of his mouth. Even if he fainted from the pain, he couldn’t let him stop. He figured he wouldn’t actually die. If he fainted once but succeeded in going all the way with him, it would actually be a win.
“Quickly, quickly….”
Unable to overcome his stubbornness, Jeil Heon brushed back the hair on Jiha’s forehead, which was damp with cold sweat.
“Relax, and try taking a slow, deep breath.”
Matching the movement of Jiha’s heaving chest, Jeil Heon rhythmically massaged his member. The organ, which had shrunk from the shock of the insertion, reacted to the spark-like stimulation even amidst the pain. He felt like he might actually become a masochist. Jiha trembled, moaning from both pain and pleasure.
The moment the scale tipped slightly more toward pleasure and the stiff tension began to unravel, Jeil Heon didn’t miss the chance and slammed his hips down. It felt as if his pelvis was splitting apart.
“Haa-ugh, ugh!”
Jiha tightened his grip, hoping that this moan would sound like pleasure. Blood flowed from the scratches on the forearm where his nails were digging in, clotting and then flowing again, but neither of them noticed.
Pushing through the tightly clenched inner walls, the member entered slowly. The meaning of his body being “opened” was vividly engraved into him. It hurt so much he wanted to sob, yet at the same time, the sensation of the other man entering him was terrifyingly good. If he truly awakened as a masochist, it was all because of this man who possessed such a monstrous thing. He really should have had him neutered back then.
Just as the regret that he should have cut that weapon down by the length of a finger surfaced, the member finally reached the deepest point. Jiha moved his trembling hand to fumble below. He felt stretched to the point of tearing, yet he hadn’t torn, and he could feel the man’s pubic bone pressing against his quivering buttocks.
“Did… did it really go all the way in?”
At the touch on the joined area, Jeil Heon swallowed a low moan and, instead of answering, caressed Jiha’s lower abdomen. Through his palm, he could feel that the inside was so full of him that the abdomen bulged slightly.
Jiha looked down at his own stomach. There must be a path carved out in his belly in the shape of the man’s member. While that thought brought a strange pleasure, seeing the protruding outline of his lower abdomen made him suddenly terrified.
Unconsciously, tears began to fall, soaking the pillowcase. Gently wiping away the tears, Jeil Heon whispered in a heavily raspy voice.
“…I’m going to move.”
Before he could even realize that the man’s voice was drenched in uncontrollable lust, his hips lurched. As the deeply inserted member pulled back, the sensation of the tightly clinging mucous membrane being dragged along was maddeningly vivid. The member, having pulled out halfway, slammed back inside again.
Every time the thrusting repeated, his stomach churned, and he squeezed his eyes shut in fear of how his bulging lower abdomen was heaving. Beyond the hand caressing his trembling eyelids, the man’s hot breath poured over him.
“Ah-huk, hng…. Does it, feel good for you, Mister?”
“Enough to make me want to devour you.”
“You said… ah, you don’t eat human flesh because it tastes bad….”
“…That’s true. I might actually get into trouble here, Jiha.”
Jeil Heon let out a hollow laugh and slammed his hips down with force. Swept up by the gradually increasing speed, Jiha’s body shook incessantly. The area that had been poked only by pain gradually grew numb, as if his senses were being paralyzed, but he didn’t mind as long as it was Jeil Heon. He was glad he could give back as much as the care he had received from him. It was worth enduring the pain without pushing him away.
Determined to hold on and not faint until the end, he clung to Jeil Heon’s shoulders. Then, Jiha realized that the pain wasn’t subsiding because his senses were numb. A strange heat was gradually layering over the heavy, dull ache. The heat spreading from the rapidly frictioning inner walls surged in like a wave. Jiha was utterly bewildered by the vivid pleasure, which was incomparable to the times he had masturbated.
Startled, he bit his lip to stifle his moans, but when a certain point of the membrane was poked deeply, a lightning-like pleasure shot through his spine.
“Hwaat! Ha-huk…! Hng!”
Startled by the high-pitched moan that escaped his lips, he bit down hard, but Jeil Heon only let out a low, vibrating laugh.
“Here it is.”
“Wha- what… ah-eung! Ng! This is, strange… haak!”
“Shh, it’s okay. It’s okay. It’s not strange.”
Jeil Heon dropped a kiss to soothe him as he floundered, overwhelmed by the unfamiliar onslaught of pleasure. Every time the member violently entered and exited between his buttocks, stirring the membrane, sparks flew across the retina beneath his tightly closed eyelids. It was the scream of a body accepting him, the fear of ignorant senses, and a pleasure that felt as if his entire body were burning.
Terrified, new tears flowed from his wet eyes. Overwhelmed by a bliss he could not control, Jiha clung to Jeil Heon, sobbing like a child. Even the soothing kisses that swept across his tear-filled eyes with a tongue were driven by an excitement that tore at his nerves.
Before he knew it, his own member had gained strength and was twitching; as Jeil Heon gripped and stroked it, Jiha ejaculated a long stream into his hand. As if wanting him to feel the afterglow of the orgasm, Jeil Heon moved his hips slowly.
“Hng, ha-ah…. hng….”
Even though he had come, his body trembled violently from the lingering aftereffects of pleasure clinging to every part of him. Only after receiving countless kisses that continued to caress and embrace his face, a mess of tears and sweat, did the trembling finally subside.
While hugging his shoulders, Jiha slightly tightened his buttocks. With just that small movement, a heavy moan escaped Jeil Heon’s lips. He could feel the member buried deep in his stomach twitching.
“Please, teach me too.”
“Teach you what?”
“How to make you… feel good, Mister….”
“…….”
For a moment, Jeil Heon took a sharp breath. Thinking he might have misheard because the voice was so small, Jiha stammered out more words.
“If you don’t teach me, I’ll, ugh, never do this with you again….”
He hadn’t even finished the sentence. Suddenly, while still inserted, Jeil Heon supported his back and lifted him up to a sitting position. Startled by the sudden change in position, Jiha let out a sharp moan the moment he ended up sitting on the man’s thighs.
He thought it would be the same regardless of the position. He was wrong. Unlike the first insertion while lying down, the change in the angle of penetration brought a new kind of stimulation. His breath hitched further as his own body weight pressed down from above. Reflexively, he wrapped his arms around Jeil Heon’s neck. Only then did he realize that the man’s body was also drenched in sweat.
Jeil Heon slowly stroked the back of Jiha, who was making whimpering sounds. For some reason, it seemed like the man was chewing back a moan in his mouth, but when he finally spoke, his voice was as tender as usual.
“Can you try moving your hips a bit? Like you’re drawing a circle.”
“L-like this?”
“…Mmm, you’re doing great.”
His lower abdomen was so tightly full that even moving was not easy. As he forced his creaking body to heave, the man patted his buttocks in praise.
However, it was obvious that his hip movements were incredibly clumsy. Compared to the man, his gestures must have been as unskilled as a child’s. Yet, Jeil Heon’s response slowed slightly, and the breath brushing against his hair grew thicker.
Even with such clumsy, slight movements, the man became fiercely aroused. Every time he recognized this fact, his head grew hot as if a fuse had been lit. The excitement that started from the heart, rather than the flesh, was just as stimulating as the pleasure applied directly.
Jeil Heon, who had been moving his hips slowly in sync with Jiha’s movements, seemed to sense his excitement, as his breathing grew even rougher. The loose movements of his hips suddenly became intense, to the point where the sound of them slamming together from below echoed loudly.
