Jungkook sat his new laptop down on his desk, plugging it in so it would be fully charged when he set it up later. Turning to Hyunji he was ready to fuck the life out of her, but she had other plans.

"Aren't you going to open my gifts?" She innocently asked.

"Of course!" He grinned.

He picked up her presents and sat on the bed with them. He started out with a small box with striped wrapping paper, opening it up and his jaw dropped. She got him a smart watch/fitness tracker just like hers, he had been planning to put that on his christmas list. He was more than surprised considering he knew it was on the expensive side.

"Hyunji, thank you so much. Are you sure though? It's expensive." He looked up at her.

"Yes, of course it's fine!" She reassured him.

"I forget you're like rich sometimes."

"Well I'm not rich, my parents are."

"Either way this is really nice, baby."

He put it to the side grabbing the next box, it was a thin rectangle leaving him guessing what it was. After unwrapping it he smiled, she made a painting for him.

"I know it's not the best-" She started.

"No, it's good. You're a good painter, this is adorable." Jungkook grinned while still looking at it.

"Inspired by our date star-gazing."

The blue hues covered the canvas as the night sky while many specs of white were the stars, a streak being a shooting star. In the middle there was a silhouette of Jungkook, even if he kinda looked like a cartoon character he didn't care. In his eyes Vicent van Gogh painted it.

"It's going on my wall." He told her.

The next box had a camera lens in it and his face when he opened it was priceless. He didn't even know he wanted it until now, but he couldn't wait to use it. Lastly she got him a leather strap to go on his camera and hang around his neck, it even had his name one it. After she noticed his old one looked like it had been through a couple wars she thought that would be a good gift.

"Babe, thank you so much for all of this. It's almost too much. I kinda feel bad you spent all of this-" Jungkook spoke.

"No, don't feel bad. I just wanted to give you presents you would like, I can't help it if you have expensive taste."

"I don't!"

"I'm joking, Kook!"

"Oops, I should've opened your card first huh?"

"No, please don't read it in front of me."

She remembered how sentimental and a little cringey she was writing it. He could read it when he didn't have the opportunity to make fun of her.

Jungkook cleared off his bed, wanting to make sure there were no obstacles in the way for when the time came. He even noticed earlier that there was a hint of lace under Hyunjis shirt, so she must've planned something, right?

"So, do you wanna open the rest?" Hyunji asked him.

Not really.

"I guess."

Hyunji chuckled, "You want me to fuck you already?"

"Oh, I'm the one getting fucked now huh?" Jungkook raised his eyebrow.

"Take off your clothes."

A grin spread across his lips.

Jungkook began stripping at her instruction, noticing her looking through her purse for something.

"What are you looking for-" Jungkook looked at her.

"Get a condom and get on the bed and don't worry about what I'm doing." Hyunji replied.

He bit his tongue and kept silent. If only she could see the smile on his face. Jungkook found it adorable whenever she tried to be more dominant, but he didn't want to ruin it for his girlfriend. So he did what Hyunji said and sat on the bed like the good boy he was.

"Is that a rope- are you tying me up?" Jungkook raised his eyebrows.

Well he wasn't expecting that.

Hyunji straddled his lap, putting her hand on his chest as she pushed him flush against the bed.

"Give me your hands. . . Unless you're not comfortable with that." Hyunji said, sarcasm in her tone.

She damn well knew that was one of his kinks. Except he probably thought he'd be the one tying her up.

Jungkook put his hands out in front of him as she began tying his wrist together. She asked him if it was too tight and Jungkook shook his head in response. Hyunji put his wrist above his head as she tied it around his bed frame. He knew he wasn't going anywhere soon.

He watched as she took off her shirt, throwing it off to the side. The lacy lingerie kept his eyes glued to her breasts as she took off her skirt.

"Wait, how did you get that on? It wasn't on in the car." Jungkook questioned.

"I put it in my purse and during the party slipped into the bathroom." Hyunji replied.

"I knew your boobs looked different."

"You mean smaller because I took off my bra.."

Jungkook entered dangerous territory.

"No, no-"

She cut him off with a kiss, one he was thankful for. Her hands cupped his face as she began kissing him. Hyunji started grinding on him, feeling that he was already hard under her heat. She noticed he gently pulled at the rope as his abs flexed under her.

"You like being tied up don't you?" Hyunji cocked her eyebrow.

"Maybe. . . I'll let you know after I judge your performance." Jungkook smirked.

"Well you make sure while you're judging you keep the fuck quiet."

"Yes, ma'am."

The last thing she needed was for Jungkooks mom to hear then fucking, that was worse than her noticing some lovebites.

Jungkook lifted his hips pressing his dick against her sopping core, whining her name.

"Not just yet." Hyunji whispered under her breath.

She placed herself between his legs, her lips attached to his thigh as he gasped. Her hand caressing his other thigh drove him crazy. He could feel his dick throbbing, pre-cum pooling at his base. The ropes at his wrist restraining him only made him feel more intoxicated. He couldn't even stop her if he wanted to and Jungkook loved that. She had eased him into being submissive without him even knowing it.

Hyunjis lips made their way up his toned body, she could feel the heat radiating off of him. He was desperate, but she was going to make him wait just a little longer. Jungkook looked down at Hyunji and watched as she dragged her tongue along the ripple of his abs. Hyunji made eye contact and noticed him biting his lips, trying to hold back a grin. Jungkook couldn't help but let out a small laugh.

Shit, maybe licking his abs wasn't the best choice.

Hyunji started blushing as she sat up. "I went too far didn't I?"

"No," Jungkook chuckled, "Don't hold back, baby. I just wish I had a picture for when I need some motivation to go to the gym."

She rolled her eyes. Hyunji took off her lace thong, throwing it on the floor next to the rest of their clothes. Her weight rested on her knees before she sank down on his dick, they both simultaneously moaned at the feeling.

Jungkook could feel the adrenaline in the pit of his stomach as she moved up and down his length. Hyunji pushed him fully inside her, feeling his hips begin to move with his as she grinded her jewel against his base. As she moved on top of him he couldn't take his eyes off her breast, they bounced with each thrust and he loved the sight. Now is the time when he'd use his hands. Jungkook would cup her breasts gently kneading them as it sent shivers down Hyunji's spine. His thumbs would circle her nipples, playing with them as his girlfriend let out a shaky breath. Lightly pinching them before moving onto another area of the goddess above him.

But he couldn't do any of that.

"Shit, Hyunji!" He sighed, pulling at the restraints.

Now he would be teasing her bud, rolling it under his thumb as he pleasured his girlfriend. But it was evident that she wasn't reliant on Jungkook to get her off. She stretched her walls with his dick, rolling against him to grind her bud on him. He felt Hyunji circle her hips around him as he watched the pleasure on her face.

Hyunji became more and more fond of her boyfriend tied up beneath her. Even when she started out being dominant Jungkook easily pulled the strings. Hyunji seemed to always slip back into submission, even if she was on top. But this time Jungkook knew his place and he wasn't trying to take over.

She enjoyed the control she had over him. His lips were parted as he sighed in pleasure. Hyunji quickened her pace as the presence of a knot in her stomach was felt and Jungkook followed suit as he moved his hips in sync with her. The feeling of her fingertips ruffling his hair made him hum as he grinned. Hyunji gripped his hair at the roots hearing him groan her name through Jungkook's lips.

"Shh, baby, you need to be quiet." Hyunji continued playing with his curls.

The moans were spilling out of him like never before, why he didn't do this when they were alone was a question Hyunji had.

He could feel the pressure of his release in the pit of his stomach. His muscles tensed under Hyunji and she saw his abs even more defined. Jungkook wasn't ready for this to end and he didn't want his girlfriend to go home.

"Ji, faster please." Jungkook spoke.

She rolled her hips into him fast and heard his bed frame gently rock against the wall. Hyunji knew he wasn't going to last, he was practically shaking under her. His hips stilled and his release washed over him. He called out her name as his body relaxed under her.

"I'm almost there." Hyunji played with a few strands of his hair.

Jungkook sloppily moved his hips along with hers, quiet moans filling her ears. Hyunji needed just a little more to send her over the edge. Coating her middle fingers in her juices she found her sensitive jewel, rubbing circles on it. Her head fell to the side as her lips parted. A few more strokes on her clit and she was clenching around him, gasping his name as her orgasm found him.

Their heavy breaths filled the room as Hyunji freed Jungkook's wrists. He brought his arms down, resting his hands on her waist, his eyes fluttering shut. Hyunji laid on his chest, listening to the continuous thump of his heartbeat. His thumb rubbed her waist as they laid in each other's warm embrace.

"Thank you." Jungkook broke the silence.

"Are you thanking me for sex?" Hyunji asked.

"No! Mom said you helped plan everything. I was thanking you for today. . . . Which I guess included sex."

"I wanted you to have the best birthday."

"I did. You know last year's birthday wish was to get laid before I was 18."

"So I made your dreams come true huh?"

"I guess. Today I wished that a year from now we're only even closer than we are now."

Hyunji smiled, "Oh really?"

She glanced at his clock, it was time for her to go home. Hyunji had told her mother she would be home for dinner and she didn't want her parents to become suspicious.

"I need to get going, Kook." Hyunji sat up, hearing Jungkook groan in reply.

"Already?" Jungkook propped himself up on his elbows, feeling the fact that he was still inside of her.

"I need to be home for dinner. We've been together all day, love."

"It's not enough, though."

"I know, I know."

Hyunji got off of Jungkook and looked for her clothes scattered around the room. She could feel her boyfriend's peeping eyes as she bent down to get her shirt.

"So what do your parents usually do for your birthday?" Jungkook asked,

"Nothing. They work and we go about it like it's any other day." Hyunji nonchalantly said.

Jungkook audibly gasped. "That's crazy!"

"Not really." Hyunji shrugged her shoulders.

"Next month you're gonna have the best birthday of your life, I promise."

"Babe, you don't need to do anything. It's nothing special, it's really just another day-"

"No, no, that's unacceptable. Wait till I tell my mom about this."

"Oh, Jungkook. . ."

 Sorry for late update. . . . . . .  Hope you enjoy!
