Good Night, Brother! - Chapter 13.5

As Yi Hyeon reached his climax, his body relaxed, and the softened tip of his member remained trapped in Eun Hyun’s lips, which refused to let go. His tongue pressed into the slit of the urethra, extracting every last drop of essence. The thick, sweet taste of Eun Hyun’s release slid down Yi Hyeon’s throat, leaving him deeply satisfied.

Eun Hyun lay limp, completely spent, his face a picture of disheveled ecstasy. Tears, saliva, and even snot trailed down his features, though he remained oblivious. Beneath him, a small puddle had formed on the smooth tabletop, the result of his overflowing fluids. His body shivered with residual tremors, appearing both pitiful and unabashedly sensual.

Yi Hyeon, noticing Eun Hyun’s trembling frame, slid his arms beneath him, lifting him with ease. The rounded curve of Eun Hyun’s pregnant belly pressed against Yi Hyeon’s firm abdomen. Startled by the sudden lift, Eun Hyun clung desperately to Yi Hyeon’s neck, his voice trembling with unease.

“C-careful!”

The feeling of being carried, with his pregnant belly exposed, made him uneasy. Only when Yi Hyeon gently placed him onto the soft bed did Eun Hyun finally relax.

Yi Hyeon began trailing kisses along Eun Hyun’s body, from his toes to the crown of his head, showering him with reverent affection. Though Yi Hyeon had always enjoyed lavishing attention on every part of Eun Hyun’s body, there was something intoxicating about the softened, porcelain-like skin that came with his pregnancy. The sensation of his lips gliding across the smooth, warm surface was utterly addictive—like savoring a confection he could never tire of. Eun Hyun’s breathy moans only spurred him on.

Marking Eun Hyun like an animal claiming its mate, Yi Hyeon left his saliva and pheromones behind as if branding him. The sight of Eun Hyun, flushed and coated in his partner’s affection, was undeniably seductive. Since becoming pregnant, Eun Hyun’s body had grown more pliant, his legs naturally falling open more easily due to the changes in his pelvis. That openness only deepened Yi Hyeon’s desire.

As Yi Hyeon toyed with Eun Hyun’s swollen nipples, lavishing them with attention, a sudden soft thump echoed from Eun Hyun’s belly. Yi Hyeon froze, his wide eyes snapping to Eun Hyun’s face.

“Hyung, was that… a kick?”

“I… I don’t know…”

It was a sensation Eun Hyun had never experienced before. Could this really be the baby’s movement? Instinctively, he placed a hand over the spot where he’d felt the faint push. The realization that the life growing inside him had its own will was both astonishing and surreal. He had occasionally felt a bubbling sensation in his stomach, but this was the first time it had been so distinct.

Yi Hyeon joined in, gently pressing his palm against the rounded surface of Eun Hyun’s belly, stroking it with careful fingers. For a moment, there was nothing, and both of them wondered if they had imagined it. Then—thump! Another, more forceful nudge pressed against the skin, sending a ripple of motion through Yi Hyeon’s hand.

Yi Hyeon’s eyes widened further, his astonishment mirrored in Eun Hyun’s expression as their gazes locked.

“Wow… Hyung, what do we do? Eun just found out we’re having sex.”

“No, that’s not—!”

“It is! I just saw it! Little Eun heard everything—the noises, the moans—it’s too late.”

“…….”

“Well, I guess it’s fine. Eun will learn about all of this when they’re older anyway, right?”

“Shut up!”

“I wonder how long it’ll be before Eun comes out and grows big enough to understand.”

Yi Hyeon’s affectionate gaze lingered on the swollen belly holding their child. His hand traced gentle patterns over the taut skin, as though committing the shape and feel to memory. His fingers circled the area near the navel, then slowly trailed downward. The light touch sent shivers through Eun Hyun’s body, heightening his awareness. When Yi Hyeon’s fingers slipped past the sensitive groin area and brushed the delicate folds below, Eun Hyun flinched.

Yi Hyeon’s fingers found the wet, waiting entrance, already slick with arousal. He slid two fingers inside, twisting and curling them expertly. The warm, wet walls clung to his fingers, and each movement sent slick fluids splattering outward. As his fingers pumped in and out, the lewd, squelching sounds filled the air, mingling with Eun Hyun’s hitched breaths.

Satisfied with how soft and ready Eun Hyun had become, Yi Hyeon pulled his fingers free. The sudden emptiness caused Eun Hyun to turn his head, biting back a moan.

“Ah…!”

Eager to take things further, Yi Hyeon pressed a kiss to Eun Hyun’s belly and murmured softly.

“Eun, is it okay if Daddy moves in here? Huh? You don’t mind, right?”

“Stop saying things like that!”

Despite Eun Hyun’s flustered protests, another bump appeared on the surface of his belly. It was as if the baby were responding, and Yi Hyeon’s grin widened.

“…See? Eun just gave me permission.”

“That’s not what it means!”

Unable to bear the embarrassment any longer, Eun Hyun covered his face with both hands. The mere thought of another life moving inside him was already overwhelming. Yi Hyeon’s playful interpretation only made it worse.

Before Eun Hyun could process his feelings, Yi Hyeon shifted him onto his side and pressed himself firmly against his back. His now-bare chest aligned with Eun Hyun’s body, and the firm heat of his arousal rested against the curve of Eun Hyun’s backside.

Anticipation swirled between them as Yi Hyeon guided himself carefully, his hand steadying his length as he entered. The tight, familiar warmth enveloped him, welcoming him in as though it had been waiting for this moment.

“Ahh…”

Eun Hyun let out a soft moan as Yi Hyeon moved, his slow, deliberate thrusts brushing against all the right places. His hands instinctively cradled his belly, holding it protectively as it swayed gently with Yi Hyeon’s movements. The shallow thrusts, though cautious, sent waves of pleasure rippling through him.

Every deliberate stroke was maddeningly gentle, stimulating Eun Hyun’s most sensitive spots while leaving him yearning for more. Yi Hyeon’s lips pressed tenderly against Eun Hyun’s temple, his breath warm as he whispered.

“You like it when I press here, don’t you?”

“Ahh… yes…!”

“It’s my birthday, Hyung. You have to tell me honestly how it feels.”

“…….”

“Hmm?”

With a deliberate thrust, Yi Hyeon angled himself to press directly against Eun Hyun’s most sensitive spot. The sharp jolt of pleasure made Eun Hyun’s vision blur, and his body arched instinctively, surrendering completely to the sensation.

“Ahh! Feels good! Hah, so good… ah…!”

Yi Hyeon continued stimulating Eun Hyun’s inner walls in a way that wouldn’t strain the womb while ensuring he could feel every sensation. The way the glans pressed and rubbed against a particular spot brought immense pleasure to both of them.

Completely overtaken by the mind-numbing ecstasy, Eun Hyun unconsciously moved his hips, chasing after Yi Hyeon’s member every time it withdrew. Their movements fell out of sync, prompting Yi Hyeon to halt his thrusts. Yet, Eun Hyun kept moving his pelvis, rubbing himself against Yi Hyeon’s glans, entirely lost in the sensation. Oblivious that Yi Hyeon had paused, he moaned freely, mistaking the stimulation as his brother’s doing.

“Ah… haah, ugh, ah…!”

“Hah, hyung… are you rubbing yourself on me right now?”

“Mm…?”

Eun Hyun, still dazed, froze mid-motion as realization struck him. Embarrassed, he immediately stopped. With a low curse, Yi Hyeon interlocked their fingers over Eun Hyun’s belly and resumed his movements, this time with shallow but rapid thrusts. Each time the heated tip of his member struck the sensitive inner walls, high-pitched moans escaped from Eun Hyun’s lips.

“Mm, ahh, haah!”

Before long, Eun Hyun’s walls began to contract tightly, and his length pulsed as he reached climax. His entire body curled inward, trembling as waves of pleasure overwhelmed him. Strings of his release painted the bedsheets in long streaks.

“Ahh…! Hah, ah, ah…!”

Bright, white flashes danced behind his tightly shut eyelids. The obscene sounds of his moans and the tightening grip of his walls were enough to push Yi Hyeon over the edge as well. With a groan, he released, his warm essence surging forth, pounding against Eun Hyun’s prostate.

“Kuh… haah…”

Both were left panting, their bodies slack as they let out heavy, satisfied breaths. Just then, there was a gentle thump—Eun shifted again inside Eun Hyun’s belly, the motion visibly lifting and then settling his skin.

“Looks like Eun liked it too,” Yi Hyeon commented with a smirk.

“N-no, that’s not… not true…”

How could the baby possibly move at the exact moment of climax? Was Eun actually enjoying it, or was this some kind of protest against their actions? Flustered beyond belief, Eun Hyun felt as if the baby had been silently witnessing their intimate moment, and the mere thought made him want to crawl under a rock.

Still eager for more, Yi Hyeon placed his hand gently on Eun Hyun’s belly, as if waiting for another movement from the baby. He trailed soft kisses along Eun Hyun’s sweat-dampened neck and ears, leaving him squirming.

“Yi Hyeon, enough… your birthday’s over now,” Eun Hyun mumbled, glancing at the wall clock, which showed five minutes to midnight.

“There’s still five minutes left,” Yi Hyeon pointed out mischievously.

“And what could you possibly do in five minutes…?”

“I’ll finish in five minutes.”

It was an absurd claim, but Eun Hyun, utterly drained from two rounds already, didn’t have the energy to argue. Barely able to keep his eyes open, he found himself unable to stop Yi Hyeon’s wandering hands. As his mind drifted toward the edge of consciousness, he made a silent vow: next year, he would definitely prepare a proper birthday present in advance.
