"Tell me the slope intercept formula" taehyung asked as he looked at jungkook

"Y=mx+b" jungkook smirked. He knew it was correct.

Taehyung looked at the answer and to be honest he was startled that jungkook actually said it right

"That's.....correct" taehyung said and jungkook clapped his hands, excited to see taehyung strip in front of him

Taehyung sighed as he kept the book on the couch and took his t-shirt off.

Jungkook stared at taehyung's smooth tanned skin, his flat belly softly going up and down due to his breathing movements

Jungkook licked his lips. This was a nice game, they could do it more often. It benefits jungkook both ways; he could fuck taehyung and also learn for the test

"Define plane geometry"

That was a bit difficult for jungkook as he thought for it for a second before gasping

"Formulas for calculations attributes of geometric shapes within a plane and solving for variables based on the angles of a given shape that are trigonometric identities" jungkook breathed as he said the definition

Taehyung was impressed. He nodded his head before taking off his slippers

Jungkook whined, he thought that taehyung was going to pull down his pants and he'd get to see the taebooty but he likes waiting for the big reveal

"Standard form of parabola?" Taehyung asked and gulped

If jungkook would give a right answer he would need to remove pants

"Shit I don't know this" jungkook said under his breath but still decided to try

" y = ax + bx + c?" He gulped and taehyung smirked

"Wrong, you forgot the square. It's y = ax2 + bx + c" taehyung smirked

"Ah fuck" jungkook groaned before unbuttoning his shirt while taehyung licked his lips as he stared at jungkook's movements

Jungkook looked at taehyung and smirked, just like him, taehyung was craving for him but he didn't want to admit it or either show it 

Jungkook threw his shirt somewhere and looked at taehyung while he was staring at his perfectly built body. Biceps, sculpted abs and hard chest.

"Like it?" jungkook smirked and taehyung rolled his eyes

"Let's head to the next question" taehyung said and he was about to ask the question but suddenly he was pinned down on the couch as he yelped

"What are you doing?!" taehyung asked

"Shh" jungkook shushed him and taehyung immediately shut up

"I noticed that you've been commanding me too much huh?" jungkook said in his dominant voice and taehyung's breath hitched. Yes, he might be the one to order jungkook anything but when jungkook slips in his dominance even taehyung gets those chills. So he shall better be quiet

The other's hand snaked towards taehyung's butt and massaged it, gripping his waist tightly with his other hand tightly.

"Rolling your eyes on me" 

Spank

Taehyung gasped as the burning sensation occurred over his lower region

Jungkook started to dry hump taehyung who bit his lip to not produce any lewd sound.

"Acting so dominant towards me" 

Spank

"Shall i teach you how to behave like a good boy?" jungkook asked as he arched his eyebrow at taehyung who shook his head.

"I-i am a good bye" taehyung said and jungkook gave a long hum, not satisfied with his answer

"Doesn't look so" he said, grabbing taehyung's neck who gasped for breath

"Suck me like a god boy you are then" jungkook ordered and taehyung nodded repeatedly and jungkook left his neck

Taehyung unzipped jungkook's pants and pulled them down a little so that the other's hard member sprung out of it, slapping over his stomach

Taehyung wrapped his calloused fingers over the other's thick dick and pumped it a few times, rubbing the pad of his thumb over the other's slit and then giving kitten licks to the other's aching member

Jungkook growled and taehyung immediately took the whole shaft inside his mouth, vacuuming the air from it, hallowing his cheeks and bobbing his head over it which made jungkook to close his eyes in bliss

Taehyung picked up his pace, while occasionally massaging the other's balls who moaned

He slightly grazed his teeth over the skin and whirling his tongue over the tip of his dick making the other shower praises to him for making him feel so good

He was about to cum but pulled taehyung's hair, detaching him from his shaft and throwing him on the couch

He swiftly removed the other's pants and boxers. He spread taehyung's legs over the couch as he himself got off the couch, facing the other's bare ass

He licked a stripe over taehyung's milky thighs and sucking some hickeys over it while taehyung was shivering a bit as jungkook's hot breath fanned over his skin

Jungkook stopped at taehyung's pink, plaited hole and stretched it apart with his two thumbs before poking his tongue inside it, while taehyung gasped and clenched the couch's arm for support, his eyes fluttering closed and moans leaving his mouth.

Jungkook whirled his tongue over the other's hole, occasionally kissing and licking it.

He detached his tongue and forwarded his fingers towards the other's mouth who immediately seemed to suck over them, glazing them with his thick coat of saliva while jungkook looked at him with lusty eyes

Jungkook pulled his fingers out of taehyung's mouth and forwarded his first finger towards the other's hole and pushing it inside while the other groaned at the burning sensation

Jungkook moved his finger inside taehyung rapidly, stretching him out and then added his other two fingers at the same time while taehyung gasped, drool coming out of his mouth

Soon, he pulled his fingers out of the other's hole and pumped his cock before prodding it over taehyung's hole.

He took taehyung's wrist and gripped them before sliding inside taehyung making him whimper

He started off with a slow speed but then picked up his pace seeing the neediness of taehyung.

He was going on full speed, his thrusts getting deeper and harder, making their skins to slap because of the contact

Taehyung was a moaning mess as drool covered his cheeks but jungkook wasn't the one to care and wipe it off

He was just here for his pleasure

And he was getting it

Soon he came inside taehyung while taehyung spurted his cum over his chest, both groaning as they came.

Taehyung was panting and whimpered when jungkook pulled out of him, the cum dripping out of his hole.

Jungkook cleaned himself and pulled on his pants before sitting on the couch once again

Taehyung calmed himself down before wearing his own clothes and looking at jungkook

"So atleast you've made a little progress. I'll be taking your test next week so better prepare for it" taehyung said

He smirked before leaning towards jungkook

"And if you pass the test, i'll give you a reward" taehyung whispered in jungkook's ear who got excited for it already

He's gonna study hard for the test

And the reward

"But since you've been giving me such nice rewards can i give you one too?" jungkook said

"I would love to get one" taehyung grinned and somehow taehyung's boxy smile tugged at jungkook's heart strings

He wanted to pretend as if the smile didn't cause any effect over him yet a slight red was flushed over his cheeks but he successfully hid it

"By the way, you know what reward i would give but what will i get?" taehyung asked

"An amusement park trip with me!"
