Lee Mark strode down the corridor, got bored at the very-familiar scene of everyone bowing at him. He walked hastily towards the office at the end of the 19th floor, which belonged to the person who was "not afraid of anyone, even his boss".

Mark didn't even knock on the heavy wood door, he just pushed it open and entered the room. His gaze only focused on the brown-haired guy who was alone in this massive luxury office.

"Mr. CEO, what need do you even have to go down here to get?" Donghyuck, or the youngest COO of the corporation's history, well-groomed in a white shirt and black dress pants, lowered his glasses and asked impassively. Mark didn't care to answer, he slowly walked to the COO's desk, bent down to look directly into those "naive" eyes, lowered his voice and ordered.

"Up."

"CEO?

"I said, up," Mark growled, his hand seized the small chin of the opposite guy. Donghyuck's body was lifted by Mark's violent action, his eyes were moist with tears "Mark! That hurts!"

He just smirked, hand gripping the other's chin to flush. Mark leaned forward, lips by Donghyuck's ears, "A slut shouldn't wince."

Donghyuck rolled his eyes upwards at him, his chin was grasped to pain. Mark walked over the work desk to get closer; before the younger could do anything, he rudely pulled down the other's smooth dress pants down to his ankle.

Mark lasciviously stared at those tight fishnet thigh-high socks on his soft thigh, with that burning-eyes black lacy panties. There had been already a bulge between his legs, mmm.

"No, Mark, there are many people out there, today I also have-" Before Donghyuck could finish his sentence, his small mouth had already been blocked by three fingers. Mark observed, satisfyingly, as the COO docilely sucked his slender fingers, and suddenly smacked on a hot asscheek under that delicate white shirt.

"Mark!" Donghyuck screamed, grabbed the wrist ready to land on his butt once again. The CEO raised his voice, the other hand squeezed that small waist "Call me master."

Donghyuck sighed quietly, why the fuck the CEO got master kink inside him, at this fucking perfect moment: right now in his fucking office?!

But he knew that there was no return, better to finish fast than to get home and be punished. Donghyuck grabbed his arms around Mark's neck, sweetly called "Master~" before dragging the older into a hot make-out session.

Mark's tongue like a snake quickly slid in, swept all the morning coffee scent from Donghyuck's mouth. The younger was plagued to be short of breath, had to let go and gasp for air. Then he just realized Mark had turned around and hugged him to sit on his chair ever since.

Mark quickly ripped the panties, the younger's dick came flinging free. He rubbed his butt against the other's growing erection. The CEO started sucking his nipple through the shirt, saliva caused a wet part of the shirt sticking sexually to his chest. Mark continuously pinched those nipples becoming bigger and redder. With one free hand he pulled the younger closer, his big cock poked in between his asscheeks, and Donghyuck's dick stuck to his abdomen.

"This little slut always wants something in its hole, huh?" Mark smacked his butt, made Donghyuck hiss, the younger took a tight hold of the older's hair.

"Oh, it only wants exactly you, master." Donghyuck smiled, pretty fingers slowly removed the disheveled cravat around Mark's neck, then shirt buttons one by one, until a burly chest appeared. Donghyuck hovered his finger on those muscles, temporarily envied that brawny body. (However, he still loved his beautiful body, the most) His cute fingers wandered on Mark's skin, then slowly crawled down to "the lair of the rising monster".

Suddenly Mark ordered, "On your knee." Donghyuck obediently climbed down, faced his big bulge under the dress pants. He made the younger do doggy style, and ordered "Only mouth."

Donghyuck's teeth unzipped the pants, so lucky that Mark had taken his belt off before. The next thing was the boxer, and the older's half-hard dick emerged. Donghyuck immediately put it in his mouth, his little tongue skillfully licked it like sweet candy.

While licking Mark's dick, the younger had the uncomfortable feeling that his bottom was being prodded. The older's toe deliberately was rubbing on his hole, but Donghyuck couldn't protest. His arms and legs started going numb, mouth going weary.

Mark patted the younger's cheek, hardly needed strength to have the younger on his laps. Those slender legs were pulled and put on his shoulders, Donghyuck's hands were trembling and he had to lean against the table behind him. The whole top-secret place was exposed.

"No, no, no Mark..." The younger shook his head vigorously when Mark quickly put a cock ring on his sensitive cock, this discomfort would knock him away soon. But the older paid no heed to his pleas. Mark made Donghyuck lie prone on the table and pushed the chair away, so he could stand up with the other's legs bending backward difficultly around his hip.

The sweat on his forehead, on his hot body, was so impervious to the temperature of the cold glass table, Donghyuck softly hissed. His nipples were rubbed and gradually harden, itching nonstop.

With his hands tied behind his back, Donghyuck could only scream when Mark abruptly slammed his erect dick straight into the younger's hole. Donghyuck bit his lips tightly, tears welled up in his eyes, and afraid if someone outside could hear. But Mark grabbed his hair, made his back arched, then a powerful voice poured into his ears.

"Isn't the room of the COO fully soundproofed? Slut, moan louder? To see if everyone knows that Lee Donghyuck is Lee Mark's slut only? Or this slut wants staff members to continue flirting with him right in front of his master, huh?" Thinking of morning story drove him crazy.

At the end of each question was a jolt, causing the younger's whole body to shake, pathetic moans could not help but escape from swollen lips. Donghyuck's mind was swept away by the rush of pleasure waves hitting him, accompanied by his oversensitive cock that wasn't allowed to release.

"Please... master... let me..." Donghyuck's broken plea mixed with moans flooding the room. Mark continued to slide in and out at a fast pace, satisfying at the pleasure of this unprepared slutty hole. What a whore.

Suddenly the desk phone rings, silencing Donghyuck. His eyes widen at the object on the table. Mark slowed down, smirking. "Aren't you going to pick up the phone?" Donghyuck took a swallow; shaking hands picked up the receiver.

"Mr. Lee, candidate Lee Jeno has arrived."

Donghyuck's mind became dazed. What should he do now?

"Why don't you invite him to go up here quickly?" Mark whispered into the younger's ear, his dick still maintained an annoyingly slow pace.

Donghyuck gasped, talking hard on the phone "Okay... lead him... come to my office..." Then he quickly hung up the phone, letting out a loud moan.

Mark leered stealthily. The game has just begun, Lee Donghyuck.
