OMF 3

“Haaut…! Nng…!”

“For now, I should save it. You have to get pregnant too. Right?”

“…Hn, nnng…. Th-Thank you…, ahng!”

Seowoo nodded his head in response to Taeseong, who spoke as if doing him a favor. Taeseong chuckled softly and spread the four inserted fingers wide. It was not easy because the hole was so narrow as if it would sever them, but the inner walls mashed as Seowoo trembled. Taeseong listened to Seowoo’s groan and withdrew his hand with the fingers still spread. The fingertips scraped against the soft inner walls as they came out.

“I put hyung’s semen well into your womb, so now you have to take mine too?”

“Hn…eung….”

Seowoo, who seemed exhausted even from just the hand play, could not even respond and only let out groans. Taeseong looked down at such a Seowoo and let out a laugh as he took out his cock with a hand thoroughly soaked in semen and lubrication fluid. Taeseong’s cock was also wet with pre-cum. When he stroked the shaft with his hand, the long, thick cock quickly made a slick, wet sound as if soaked in water. Taeseong aligned the glans with Seowoo’s quivering hole and then pushed his hips forward.

“Aah…. Hoo…, fuck.”

“Euhn…, haaut…!”

“Ha…. As expected, thrusting into a place where hyungs have already ejaculated is the best. It’s fucking natural lubricant.”

Taeseong tilted his head back and lowered his eyes, savoring the chewy texture of the inner walls. The thick cock slid smoothly into the hole smeared with the semen Taegang had ejaculated. It was an ecstatic sensation no matter when he entered it. Lubricant was necessary to penetrate Seowoo’s hole, which lacked lubrication fluid, and Taeseong enjoyed inserting into a hole where his brothers had already ejaculated semen beforehand. The abundant, viscous semen from his brothers was smoother and chewier than any lubricant.

“Ah, fuck….”

“Hn, Taeseong, ah…nnng!”

“It’s fucking good…. Haa….”

Taeseong slowly began his hip thrusts while enjoying the taste of Seowoo’s hole. The hole, which had become extremely sensitive, twitched and clung stickily. Seowoo squeezed his eyes shut at Taeseong’s cock moving in and out of the hole at a slow pace. It was a slow yet persistent movement, to the point where he could even feel the veins standing on the cock shaft. It was a completely different sensation from Taegang, who had thrust so rapidly that it was hard to keep his wits about him.

“Haah…ah, Tae, seong…. Aah…!”

“Does it feel good? Hoo…. You’re crazy about alpha cock. Born for it, Joo Seowoo?”

“Ahng…hng…!”

Taeseong felt the fully loosened, soft inner walls and quickly snapped his hips upward. The sticky hole clenched strongly as if grabbing the withdrawing cock. Feeling the tightness, Taeseong raised the corner of his mouth. As expected, it was a born hole. He slowly traced the rim of the hole, which was stretched taut to accommodate his cock. He let out a satisfied sigh as he felt the smooth texture.

“Haa…. You’re fucking delicious, Seowoo.”

“Hn, haah, hng…! Aah…!”

Taeseong’s large, thick balls slapped wetly against the smooth perineum. Taeseong, who had burrowed deeply into the hole to the point of squishing his balls, searched for the cervix with the tip of his glans. Feeling the ecstatic sensation pressing on the glans, Taegang tilted his head back and closed his eyes. A low groan burst from his handsome, well-shaped mouth.

“Kngh…! Hoo….”

“Haaut! Ah, ahng, hnng…! Nn, hnng….”

The alpha’s semen shooting into the cervix and wetting the inner walls was felt. As expected, it was a large amount, boasting his reproductive ability as an alpha. The alpha brothers in this family had a lot of semen. Seowoo did not know if all alphas were like that or if it was just them. He simply did his best to receive the always abundant semen that filled his hole to overflowing. On days when he received a lot of semen, his insides felt bloated, but he did not want to spill even a single drop. Seowoo, with his eyes unfocused and relaxed, clenched his hole. He tightened and closed the hole so that the semen Taeseong had ejaculated could be absorbed into the womb.

As Seowoo clenched his hole and gripped the cock, a glurping sound arose as white semen flowed out. Taeseong’s eyes sparkled as he looked down at the hole dirtied with opaque slime. He gripped each of Seowoo’s buttocks with one hand and kneaded the soft flesh as he slowly withdrew his hips.

“Eh, Taeseong, ah…. Not yet…, wait, just a mo…!”

Seowoo, feeling Taeseong’s cock that had filled his insides withdrawing, turned his head with a face streaked with saliva and tears. A smile spread across Taeseong’s lips as he gazed at the maddeningly alluring face.

“I’ll fill you until your belly bursts, so don’t worry.”

As Taeseong pulled out his cock, Seowoo, who had lost his strength, wobbled on his knees and collapsed onto the bed. The pain in his knee came belatedly. Seowoo, who had twisted his body sideways and lay down while squirming, let out a groan as he touched his knee. He felt semen trickling down from his buttocks.

“What’s wrong?”

Taeseong swatted away Seowoo’s hand that was caressing his knee. The knee, which had been clean without a single scratch, was swollen red. When he poked the reddened knee with his finger, Seowoo flinched and let out a groan.

“Ah! Eung….”

“…Does it hurt?”

“I-It’s f-fine….”

His face clearly did not look fine at all. To think he had endured receiving from behind on his knees in that state until now made Taeseong sigh.

“If it hurts, say so. You’re fucking stupid.”

“…It doesn’t hurt. I’m fine.”

“Bullshit.”

Taeseong furrowed his eyebrows and clicked his tongue in displeasure. Although he got along reasonably well with Seowoo, his affection waned every time he saw something like this. It seemed like he was showing off how dumb and uneducated he was. As expected, he was not a suitable match for the family.

“Put some ointment on it later.”

“It’s fine though…”

“Fuck, listen when I tell you.”

“…Y-Yes.”

Taeseong let out repeated sighs and grabbed the white buttocks. Because he was lying on his side with his legs together, Seowoo’s white balls protruded plumply below his hole. Taeseong lifted one buttock upward and looked down at the balls, then extended his finger and plunged it into the soft balls.

“Ahng…!”

Omegas inherently had almost no balls. It was only natural since they lacked reproductive ability. However, Seowoo had fairly plump balls protruding, perhaps because he was half beta. Of course, they were incomparably small compared to an alpha’s, but they were clearly heterogeneous for an omega’s.

“Taeseong…. Ha, stop…. There…”

That was why Seowoo also saw his own balls as a complex. He knew better than anyone that he could not become a complete omega. He had shed tears over his own appearance that seemed neither beta nor omega. As an omega existing to receive the semen of the alphas in this family, he believed that worthless balls like these should not exist. Perhaps that was the reason Taegang was so cold to him.

“They feel so fucking soft.”

But Taeseong giggled as if teasing such a Seowoo and tormented the small balls. Seowoo’s small hand tried to block Taeseong’s hand that was poking his balls, but it was easily brushed away.

“An omega with dangling balls. It’s fucking hilarious, really.”

“…Hnng.”

At Taeseong’s words, Seowoo finally burst into tears. He tried not to make a sound, but an inexplicable sorrow welled up. He chewed on his lower lip to hold it back, but he could not hide his roughening breaths.

“Hey, are you crying?”

“…Hngg.”

“Anyway, you cry over every little thing, fuck.”

“…”

“Hey…, hey!”

“…Ahng!”

Taeseong, who had been poking the balls with his fingertips, began kneading them by cupping them in his palm. The soft balls were mashed roughly in the large hand. Seowoo trembled as he grabbed Taeseong’s wrist that was gripping his balls.

“I think this is pretty okay, actually.”

“…Re-Really?”

“Yeah. This kind of thing is a unique delicacy.”

“…N-Nnng…!”

“It even has a bit of the taste of fucking a beta bastard.”

“Hn…. I-I’m not, not a beta…!”

“I know, fuck. It’s just a figure of speech. You fucking don’t get it.”

When he spread the hand that had been mashing the balls, the once white skin was flushed bright red. He pinched and shook that spot, like a ripe fruit, with two fingers. Seowoo let out a groan mixed with sobs.

“Ahng…! Hnng. What if it bursts, hnaa…!”

“Why? Didn’t you hate this? Should I burst it for you?”

“No, don’t…! Ahngk…!”

Taeseong looked down at the tearful Seowoo and burst into laughter as he withdrew his hand. The blood-engorged balls were ripened red as if they would burst at any moment. Since he had no real intention of bursting them, he stopped there.

Taeseong grabbed the skinny thighs and spread them apart, then sat down between his two legs. The spread center drew his gaze. The cock and balls, which were fairly large for an omega, and even the smooth perineum below were smeared with semen. The hole was hidden between the plump buttock flesh. It was surely quivering as it leaked the semen he had ejaculated.

“Ag-Again, again…, are you going to do it…?”

“You asked me to ejaculate semen.”

“…It hurts there, it hurts…. Can’t we stop now…?”

“…Seowoo. You’re my personal cock hole, aren’t you?”

“…”

“When I say I’m going to thrust in, you have to obediently spread your hole. Right?”

Taeseong caught his breath and then urged him in a low voice. Taeseong would laugh and joke around, but he would quickly lower his voice and get angry.

“Right?”

“…Yes.”

“Yeah. Then fuck, just say thank you and take it. Don’t say useless things.”

“Yes….”

Taeseong, who had spread Seowoo’s legs wide, aligned the glans with the hole and thrust it in at once. It was a somewhat irritable movement. Feeling the cock burrowing roughly, Seowoo squeezed his eyes shut. Since he was the same age as him and the only one who actually talked to him, Taeseong felt somewhat comfortable. He had a mischievous side and spoke harshly, but he seemed to care for him in his own way. That was why he had uttered words he could not even say to the other brothers. Seowoo blamed his foolish self.

“S-Sorry…. Sorry, Taeseong…. Hnng!”

Taeseong lifted Seowoo’s skinny thighs. He gripped the thighs with both hands and pulled them as he thrust his hips even harder. Seowoo let out a piercing cry at the fierce insertion.

“Ahngk! Hnngt! Hnng…! Aut…!”

“Hoo…. Cock hole bastard, getting above yourself, fuck…”

Taeseong withdrew his hips so that the glans ridge caught on the hole, then thrust deeply until his balls touched the perineum. The fierce insertion repeated. It was a strong movement that made his insides tingle. Every time the thick, long cock clawed at the inner walls as it thrust in and withdrew, his stomach throbbed. It was a painful insertion.

“Hnngk, ahng…! Taeseong…, eungk!”

Taeseong looked down at Seowoo, who was twisting his body and groaning, and grinned. He was not greatly angry at Seowoo’s action of asking if it hurt and whether he would insert anyway. He knew that compared to his brothers, he thought of him somewhat comfortably. That was not a big problem either. However, he must not forget his own duty. Seowoo was their omega who had to spread his legs whenever Taeseong and his brothers wanted. Therefore, it was necessary to let him know what would happen if he refused that.

“Ahng! Hn, haaah!”

The inner walls, which had become mushy and loosened from receiving Taegang’s cock followed by Taeseong’s, softly enveloped the cock. Taeseong caressed the rim of the hole and then slowly pushed in his fingers. He felt the hot inner walls with his fingertips.

“Hngk, it’s tearing, tearing…! Tae, aut…!”

As he burrowed into the hole that was already stretched to its limit, the delicate skin stretched taut. It was a precarious sight, as if it would tear just as Seowoo said. Nevertheless, Taeseong pushed his fingers even deeper.
