“Ugh.”

The finger that had entered was slowly moving in and out.

The sensation of being stretched, despite being loosened, was new, causing me to flinch and turn my head to the side, squeezing my eyes shut and letting out a moan.

“Does it hurt?”

“It, it feels str—ugh.”

In response to Taeshin’s question, I opened my eyes and answered, but moaned as his finger, which had left my body, returned with added pressure.

The finger, now digging in and out, moved more deliberately this time, causing me to whimper.

“Sunwoo…”

“Uh, Taeshin… ahh!”

The hand that was spreading and bending the finger inside me became thicker.

This time, it felt more like I was being filled rather than just something entering me.

My body trembled and tensed as I felt the finger pushing deeply inside me, and my own body tightened around it.

As my body gradually relaxed, the finger moved back inside, stirring, then bent and scraped as it exited.

“Ugh.”

A tickling sensation spread from the finger prodding below.

The heat and itchiness that rose from somewhere between my face, heart, and stomach made my body squirm.

Ah, more… just a little more.

The growing itch and unfulfilled desire made me feel a pang of disappointment when the finger withdrew.

Just as I craved for a more satisfying, deeper scratch, Taeshin frustratingly pulled away.

But only for a moment, as Taeshin, having removed his pants, pressed his body against mine again. The state of Taeshin’s body, stripped down to his underwear, clearly showed how aroused he was.

I wasn’t the only one excited and impatient from the pheromones of my heat.

Taeshin was also aroused to the limit by the omega pheromones from my heat cycle.

Only then did I start noticing the things I had missed in my excitement.

Taeshin was drenched in sweat, and he was struggling to suppress the explosive urges caused by my omega pheromones to the point where his eyes were glazed over.

“Moon Sunwoo.”

The low, calm voice called out to me. Instinctively, I wrapped my arms around Taeshin’s back as his voice, slightly panting like a sigh, filled the room.

Soon, Taeshin gripped my hips with one hand.

When he had removed his underwear earlier, his penis was so hard and erect that it bounced against my buttocks.

“Tell me if it hurts. I’ll wait.”

I had thought so when I saw it, but feeling it against my body confirmed it. It was huge. For a moment, I wondered if it could even fit, but soon the pressure of it pushing inside turned my mind blank.

“Uh, uh, ugh!”

“…Relax.”

Yes, I had learned that sex could be painful.

I had been taught to take time and loosen up my body well. But this wasn’t just about being well-prepared.

When my legs spread and his hot, erect member began to enter, my breath caught in my throat.

Taeshin had used his hand earlier, but now in practice, the pressure and its size were overwhelming.

From the very start, the fully filled member caused a sharp pain below.

As I trembled and moaned, Taeshin gently stroked me.

He said he’d wait if it hurt, but shouldn’t he just pull it out at this point?!

“Ah, it hurts… it hurts…”

“Sunwoo.”

“Ugh, Taeshin…”

The pain was so intense that tears pricked at my eyes.

As I cried and squeezed my eyes shut, Taeshin, slightly sweaty, stroked my tear-streaked cheeks.

Then he gently kissed my lips and grasped my member, stroking it.

His pheromones grew stronger as he caressed my pain-ridden, tense body.

The alpha pheromones designed to entice an omega quickly took over my entire being.

The powerful pheromones made my fingertips tingle and my breath catch, causing my body to go limp.

My skin burned with excitement and stimulation, and every part of me that touched Taeshin felt like it was on fire.

“Ugh! Ahh! Ah…!”

Responding to Taeshin’s pheromones, my own omega pheromones flared up again. My previously tense lower body became limp, and slick fluid began to ooze out.

“Slowly, breathe. You’re doing well.”

“Ugh… Ah…”

His member slowly pushed into the tight hole that had previously been blocked.

As it gradually entered, splitting the narrow flesh, a peculiar joy filled me.

Just a little deeper… please, just a bit more.

“Ugh…”

“…Ha…”

The hot hard thing of Taeshin penetrated deeply and nudged the end.

After a long entry, Taeshin stopped moving. My insides were filled completely with Taeshin’s member.

With every breath, the sensation of being fully filled inside me was vivid.

“Ugh…”

I couldn’t stop moaning. The fullness inside brought an inexplicable feeling of satisfaction.

I was beginning to realize what I had always felt was missing during my heat cycles.

“…Feels good.”

I muttered unconsciously, lost in the sense of fulfillment.

In response to my involuntary words, I heard a soft laugh from Taeshin.

“Feels good, Moon Sunwoo?”

“Ugh, yeah…”

Taeshin caressed my cheek as I squirmed from the ticklish sensation.

His hand, warm and flushed like my face, felt good as it touched me.

“Sunwoo, Moon Sunwoo.”

“Ahh, Ta, Taeshin. Ugh.”

“I’m going to move. I’ll be inside and thrust hard. Got it?”

“Yeah, yeah… hurry… hurry…”

“So impatient…”

Teasingly whispering in my ear, Taeshin lifted his upper body and gripped my waist and one buttock.

Slowly, he began to withdraw his member. The thick member dragged against my narrow walls as it exited.

“Ugh!”

Feeling a sense of loss as it left, I moaned when it slowly began to push back in. As it dragged roughly inside, I tensed up.

When my muscles tightened around him, Taeshin paused, then resumed moving when I relaxed.

Slowly in, slowly out. Again in, again out. And again.

With the repeated motions, my body relaxed.

Even when tensed, it began to accept Taeshin’s movements more smoothly.

The slick fluid from my omega body made it easier and more seamless for Taeshin to move within me.

“Ugh, ah… ha…”

Every time Taeshin withdrew and thrust back in, a new sensation awakened in my mind.

The unfamiliar ache inside was heating up, coiling together, and my mental satisfaction demanded more.

It’s already good, so what more could there be?

I thought hazily, moaning, as my mind sought more under the pressure of Taeshin’s repeated thrusts.

And when Taeshin pulled out only to thrust back in again…

“Ugh!”

“Argh.”

My vision flashed, and my body jerked.

I felt my hair stand on end along my spine, making me gasp and shiver.

“Ooh, ah, ooh, huh!”

Taeshin let out a short groan at the sudden tightening and moved a few more times before he began to thrust deeply.

The wet sounds followed his movements, echoing through the room.

Each thrust brought the same dizzying sensation I had felt earlier.

“Ah, ah, Taeshin, Taeshinaah….”

“Ha, Sunwoo….”

Every time Taeshin’s sharp thrusts hit my inner walls, my vision flashed. My ears rang, and I struggled to breathe.

I clung to Taeshin, trembling from the intense pleasure that spread through my body from my tailbone.

The sensation was like feathers tickling my lungs, making it hard to breathe.

“Ah, ah, huh!”

“Ugh.”

“Ah, ah, ah!”

The relentless thrusting felt so good.

Chasing the endless pleasure, I wrapped my legs around Taeshin’s waist.

He gripped my hips and thrust into me fiercely.

Even the slightest movement made my entire body feel like an erogenous zone.

Clinging to the edge of an abyss, I dug my nails into Taeshin’s back, sweat soaking my fingertips.

It was a thin line between heaven and hell.

The intense pleasure made me cling to Taeshin even more tightly, fearing the overwhelming sensation.

“Ah, go, go… Taeshin, now….”

“Go.”

I cried out in pleasure, clinging to Taeshin. His rapid thrusts made me moan like an animal. My body tensed, and I held my breath.

As I trembled, Taeshin gave a few more thrusts before burying himself deeply inside me.

“Ugh…!”

A hot burst erupted inside me. As my body twitched with the aftershocks, Taeshin caressed me, planting kisses on my skin.

His kisses grew slower and deeper, his tongue exploring gently.

“Ugh.”

Taeshin withdrew from me.

A warm liquid flowed out along the path his member had taken. As I felt the unfamiliar sensation of something dripping from me, Taeshin stroked my cheek, then positioned himself to support my legs.

“Ah… good….”

Taeshin pushed his member back into my twitching entrance.

As he filled me, I let out a heated moan. Taeshin gave me a light kiss.

“I’ll keep making you feel good, Moon Sunwoo.”

Taeshin said with a mischievous smile. And he kept his word.
