"Awww, look at you begging so prettily. Fine, my pretty boy will get what he wants..so be good sweetheart."

He didn't make him wait any longer, as he had asked, he wanted it just as badly.

He pushed Beomgyu's shorts down his hips, and then his own, unbuttoning his shirt as well, throwing it so some corner he could care less about right now, freeing themselves from the constricting fabric, his eyes never leaving his husband's.

"So beautiful and needy...my pretty boy."

Beomgyu whimpered softly as the cool air hit his already overheated skin, the rush of sensations only increasing the ache in his body.

Yeonjun's voice was like a drug, that deep, commanding tone making him go weak. He loved it when Yeonjun called him his, it made him feel wanted, desired, loved.

He spread his legs wider, inviting him in, "I'm only needy for you."

"Yeah?"
Yeonjun's tone was cocky, but his breath hitched at the sight of Beomgyu opening up for him, all flushed and pleading.

He leaned down, capturing Beomgyu's lips in a hard kiss, his tongue delving into his mouth, tasting and claiming him. Beomgyu responded to the kiss hungrily, their open mouths and wet tongues creating a mess of heat and need.

As Yeonjun kissed Beomgyu, his free hand found the small bottle of lube he usually kept in his bedside table, and uncapped it.

Beomgyu gasped and broke the kiss for air, but the gasp turned into a low moan when he felt a finger press against his entrance.

Yeonjun's fingers, slick with lube, worked quickly but gently, preparing Beomgyu, stretching him open. All the while, his mouth was busy tracing patterns over Beomgyu's neck and chest, his tongue leaving a path of wetness in its wake.

"You look so beautiful, darling... so good for me..." he murmured against his skin, his voice low and sultry.

Beomgyu could barely string a coherent thought together, the sensations coursing through his body were too distracting. Yeonjun's fingers, his mouth, his words, they all combined to drive him insane with need.

He writhed beneath his husband, desperately trying to get more, "Yeonjun.... please... I'm good, I'm ready. I need you..."

The sound of Beomgyu's begging, his breathless and needy voice, was like music to Yeonjun's ears. He couldn't resist him, and he knew Beomgyu couldn't wait another second more.

He withdrew his fingers, moving so that he was positioned between Beomgyu's thighs, his hardness pressing against his entrance.

"Be good for me," he murmured, his voice rough. "Just relax...I'll take care of you.."

Beomgyu felt a shiver run down his spine as Yeonjun's words washed over him.

He took a deep breath, letting himself relax beneath his husband, trusting him completely. "Please..." he breathed out, his voice shaky, "take care of me... I'm all yours..."

Yeonjun let out a shaky breath, his heart pounding against his chest at those words. He leaned down, his lips finding Beomgyu's in a tender kiss, one hand sliding down to grip his hip, while the other moved to intertwine their fingers together.

Slow and gentle, he pressed into Beomgyu, the tight heat overwhelming his senses, but he didn't rush.

Beomgyu's breath hitched, the feeling of being filled, of being so utterly connected to the man he loved so much, it was intense, and beautiful. There was a slight burn, a twinge of discomfort, but it faded quickly as pleasure took over.

Yeonjun took his time, watching Beomgyu's face, looking for any sign of discomfort. "You alright Beomie?"

"God, yes..." he breathed out, feeling tears pricking at the corners of his eyes.
"I'm okay, I'm good...just don't stop...don't stop."

Yeonjun pressed a kiss to Beomgyu's forehead, as he started to move, his hips rocking into Beomgyu's, a steady, slow pace.

He continued to hold his hand, keeping their fingers intertwined as he moved slow and steady, letting Beomgyu adjust to his size.

The sounds coming from Beomgyu, the words, the look in his eyes, it was more than he could handle.

"You feel so good, darling," he murmured, breath ragged, "so damn good. I...love you so much.."

Beomgyu's eyes fluttered shut, a mix of sensations overwhelming everything. The feeling of Yeonjun inside him, the way he was moving slowly, how he had gripped his hand, it was all just so much.

"I love you, too...so much, so damn much..." he gasped out, his words broken and breathless, "Yeonjun...faster...please."

At the needy request, Yeonjun's control started to break, the last threads of his restraint slipping away. He shifted, changing the angle, and then started to move faster and harder, still gentle but more insistent.

"Anything for you," he grunted out, his pace increasing.

Beomgyu arched off the bed, a series of loud moans escaping his lips as he gripped onto Yeonjun's hand as if to ground himself. It was almost too much, the intensity and overwhelming pleasure nearly sending him over the edge.

Yeonjun leaned down, his face buried in the crook of Beomgyu's neck, his mouth seeking another sensitive spot, his teeth sinking in, marking it.

"Yeonjun...I-" he choked out, his voice shaky and desperate, "I'm so close....don't stop...don't stop...."

Yeonjun was also nearing the edge, the way Beomgyu responded to him, the way he fell apart in his arms, it was all pushing him closer and closer.

He moved faster, his name falling from Beomgyu's lips spurring him on. One of his hands snaked down, gripping Beomgyu's hip, his fingers digging into the skin.

"Come for me" he murmured against the sensitive skin of his neck, his breath hot and ragged.
"Let me see you come... come for me Darling."

Beomgyu's body seemed to respond instinctively, as he came undone underneath Yeonjun. His back arched, his vision went white, and he saw stars as pleasure ripped through him, like a wave crashing down on him, washing away everything but Yeonjun.

"Yeonjun..." he gasped out, his voice nearly a sob, "...love you...so much...oh god, I love you..."

As Beomgyu came, the sight and feel of him, it sent Yeonjun over the edge as well, his body trembling, the grip on Beomgyu's hips tight enough to bruise. He groaned out his name, his whole body taut with pleasure as he came all over Beomgyu's thighs and stomach, falling on top of Beomgyu.

For a few moments, there was nothing but the sound of their ragged breaths, the aftermath of pleasure still coursing through their bodies.

Yeonjun collapsed beside Beomgyu, pulling him closer, their bodies entwined, his arm wrapped protectively around him, "You...are so damn perfect."

Beomgyu snuggled into Yeonjun's chest, his body still trembling slightly, aftershocks from his orgasm sending pleasant shivers down his spine. He felt safe, loved, and utterly whole in his husband's arms.

"You're the perfect one" he mumbled against Yeonjun's skin, his voice soft and satisfied.

"You left marks didn't you? You possesive dumbass, now I'll have to wear turtle neck to Uni today."
He huffed playfully, nuzzling into Yeonjun's side.

Yeonjun chuckled, his fingers tracing idle circles on Beomgyu's bare back, "Guilty as charged."

He sounded unapologetic, his voice still raw from their activities.

"I like marking you up," he admitted, "makes you mine. And it's so much fun knowing that you'll have to cover them up, hiding my marks from the world."

Beomgyu rolled his eyes, a small laugh escaping his lips. He knew Yeonjun couldn't help his possessive nature, and he secretly found it endearing.

"You're such an ass. You know people are gonna tease me about it."

"Well well, your students should know their handsome Professor is taken."
Yeonjun teased, tracing his face with affection.

Beomgyu let out a huff of mock annoyance, but there was a hint of a smile on his lips.

"You're insufferable."

He closed his eyes, enjoying the soft, lazy afterglow.

"And I'm not just handsome. I'm a goddamn angel and you know it." he grumbled, burying his face into Yeonjun's chest.

Yeonjun chuckled again, pulling Beomgyu closer. He loved this time after sex, when they were still tangled together, their bodies warm and satisfied.

"You're right, you're an angel," he agreed, his voice light and teasing, "and I'm the devil who managed to drag you down to my level."

He placed a kiss on the top of Beomgyu's head, his fingers now playing with the strands of his silky hair.

"Yeah yeah, now this Angel has Maths lessons to teach and assignments to grade, let's get up."

Yeonjun groaned dramatically, his grip on Beomgyu tightening.

"Can't you call in sick for a day?"

He knew the answer before he even asked. Beomgyu was always responsible, dedicated to his job.

But he loved to test the limits.

"As much as I'd like to do that, I sadly can't."
He chuckled, untangling himself from Yeonjun's arms and picking up the discarded shirt on the edge of his feet, putting it on.

"Your office needs their CEO too, don't they?" He teased.

Yeonjun watched as Beomgyu got up, sliding on his shirt and hiding away all the marks he had left on his body.

He pouted dramatically, trying to make it seem like he was sulking, but his eyes sparkled with amusement.

"Fine, fine. Ruin my dreams of having you all day to myself. Just go to your college, have all those handsome college boys ogling my husband."

Beomgyu rolled his eyes at the dramatics, knowing full well that Yeonjun wasn't being serious. Still, he knew how territorial his husband could get, so he decided to tease him a bit.

"Oh, you're so right, I'd definitely be checking all of them out. After all, there's some pretty eye candy in my class, you know? Tall ones, strong ones, cute ones...."

Yeonjun's possessive streak flared up, his eyes narrowing slightly even as he tried to keep his tone light.

"Oh yeah? You think they're all that, huh?"

He pretended to be disinterested, but his next words betrayed him.

"Are they taller than me? Stronger than me?"

Beomgyu bit back a smirk, knowing he had struck a nerve. He was enjoying this banter way too much.

"Oh, some are taller... definitely more muscular. And some have the cutest dimples when they smile."

He moved to stand in front of Yeonjun, leaning down to whisper in his ear.

"Why, you jealous?"

Yeonjun's jaw tightened at Beomgyu's words and the feel of his breath against his ear hit him. He tried to maintain his composure, to keep up the act of not caring, but it was becoming harder by the second.

"Jealous? Me? Pshh, why would I be jealous of some college kids?"

"Oh my gosh you're so cute."
Beomgyu giggled, pinching Yeonjun's cheeks who just huffed and rolled his eyes.
"Ofcourse I only have eyes for you, Junie."

Yeonjun tried to keep up his scowling, but the sound of Beomgyu's laughter, the touch of his fingers on his cheeks, made it impossible.

He grumbled, albeit half heartedly, "I'm not cute. I'm a powerful CEO."

He then wrapped his arms around Beomgyu, pulling him closer.

"You better only have eyes for me. You're married, remember?"

Beomgyu chuckled, letting himself be pulled into Yeonjun's strong embrace, loving the way he always enveloped him completely.

He pressed a kiss to Yeonjun's jawline, his voice dropping to a more serious, affectionate tone.

"I was just messing with you, you know. I only see you. I only want you. I'm completely yours."

Yeonjun's heart skipped a beat at Beomgyu's words, the sincere, unwavering declaration of love and loyalty. It seemed to soothe the possessive beast that often reared its head in him.

He held him tighter, burying his face in Beomgyu's soft hair, inhaling the familiar scent.

"If anyone tried to hit on you, I'd destroy them," he mumbled, his voice still gruff in a comical attempt to sound intimidating.

"Sure sure, you will." Beomgyu giggled, earning an onslaught of kisses on his neck from the older, making his squirm and shriek.

"A-ah stop attacking me! No round two please, I have a class to teach!" He laughed, making Yeonjun giggle as well, as they stayed like that for a while enjoying each other's warmth.

Despite the morning starting glum and filled with insecurities for Beomgyu, it was now giggles and hushed whispers of love, only for him, in their own little bubble.

The variable Beomgyu was so worried about, never even had a negative sign, it was a plus all along, helping him to solve this equation of Love of his.

It never mattered, because, the equation of Beomgyu's and Yeonjun's love, would always have a positive solution.
