"what the hell are we watching?!" donghyuck's eyes widened as he almost choked on his saliva as the rich man inside the movie showed his bdsm room to the college girl without a shame.

"h-huh..." mark stammered. "f-fifty s-shades of- "

"we're watching fifty shades of grey?!" donghyuck yelled. "why didn't you tell me we were watching that?!" he asked, his heart pumping even faster in his chest. "why did you even want to watch that?!"

"well... dahyun has been... wanting to watch it with me and... and i've never watched it before, and i know that if we watch it, i'll be panicking because i won't know what to do so... so i wanted to watch it once before, to know... to know how to act, and not to be surprised by everything that would happen..." mark explained, shyly looking at donghyuck with flushed cheeks. "and... maybe... i mean... since you're my teacher... you could tell me what i should do with dahyun..."

donghyuck couldn't believe what was happening.

first of all, he was watching a quite erotic movie which included sexual pratiques such as bdsm and much more.

second of all, he was watching that with mark, the boy that had been all over his mind for the past few days.

third of all, mark had just told him that he wanted him to teach mark more, and donghyuck wasn't sure he would be able to hold himself back this time.

"m-mark, are you sure this is a good idea...?" donghyuck asked, gulping as mark's orbs stared at him like he was his last hope.

"please, donghyuck... help me..." mark whispered, looking right into donghyuck's eyes, making the younger boy go crazy.

donghyuck sighed, wrapping his arms tighter around mark's waist and pulling the boy fully on his lap. "alright, let's watch it, then..." he declared, making mark smile.

the two boys stayed silent, ignoring their crazy hearts doing summersaults in their chests, and ignoring the goosebumps that were littering their skins every time the sexual tension would become palpable in the movie.

both had obvious bulges into their pants, not because of the erotic movie, but more like because of the wild thoughts the movie created in their minds involving each other.

donghyuck's body felt burning hot, and he was really hoping that movie would end soon, because the feeling of mark's body just on top of his growing boner wasn't a good thing. it would make him do things he'll regret later on.

mark completely lost it when the screen displayed an actual sex scene.

it was as if his body had reacted onto his own, turning around on donghyuck's lap and finding himself straddling the younger boy, making their bulges collide.

"w-what are you doing...?" donghyuck asked, swallowing a moan.

"i'm thinking of... kissing dahyun now... because i won't be able to watch that happening next to her..." mark announced, looking at donghyuck with pleasing eyes.

"and... i'm dahyun...?" donghyuck raised a brow.

"just to help me keeping my girlfriend, please..." mark begged.

donghyuck gulped once again, his eyes flicking from mark's eyes to his flushed cheeks, and then to his pinkish lips.

he tried his best not to give in. he tried his best to hold himself. but mark was so tempting, and he was already so aroused to think about something else now.

so, he let his body act.

"imagine i'm dahyun, then."

donghyuck leant forwards, his hands pulling mark closer at the same time, causing their lips to collide.

mark let out a whimper, his hands tangling into donghyuck's hair as he replied to the kiss.

he closed his eyes, hoping that it would help him imagining dahyun's face, to make it seem like he was kissing her.

tongues were soon added into the kiss, and donghyuck and mark fought for dominance, mark loosing almost immediately because of donghyuck's strength. at that point, mark was a moaning mess, and he was completely dominated by donghyuck.

"d-dahyun doesn't kiss me like this..." mark stuttered, opening his eyes and pulling away from the kiss for a second.

"well, then keep your eyes open and acknowledge you're making out with me." donghyuck whispered against mark's lips.

before mark could argue further, donghyuck pushed him down on the sofa, hovering over him as he glued their mouths again in a wild kiss.

both mark and donghyuck were driven by their lust, kissing with more vigour than they ever had, and grinding their growing members together, making each other moan loudly.

the movie had been long forgotten, neither mark nor donghyuck noticing that the sex scene had ended, meaning they could cut their little session short.

no, instead, donghyuck stood up from the sofa, pulling onto mark's shirt to make the older boy stand up as well. they lips met once again when both were standing, and donghyuck's hands sneaked behind mark's thighs, forcing them open so that he could carry him.

mark's arms wrapped around donghyuck's neck as he never detached his lips from donghyuck's.

with his hands holding the older boy's butt, donghyuck drunkenly walked across the corridor to get to his room, not taking the time to switch the tv off.

"mmh..." mark moaned as his back was slammed against the door of donghyuck's room, while he was still in the younger's arms. donghyucks hands groped mark's butt harshly, making mark moan again, and soon, donghyuck had thrown mark onto the bed.

mark took this opportunity to breathe as he stared at donghyuck approaching him, lust glistening in his eyes.

the older boy gulped as donghyuck made him sit up and grabbed the hem of his shirt to pull it off and throw it somewhere on the floor. mark was the one to glue their mouths again when donghyuck had leant over him.

the feeling of donghyuck's bare chest against his was electrifying, and mark moaned beautifully at the sudden rush of emotions. this didn't help his throbbing member to calm down, as his lower region started to hurt because of the tightness of his trousers.

mark quickly reached for the button of his jeans, opening it while donghyuck sucked hard on his lips. a breathy moan left mark's lips as it was freed from the cloth cage it had been locked in since the beginning of the day.

"w-wait..." donghyuck pulled away, sitting on the bed as mark did the same in front of him.

both were panting hard, and their cheeks were flushed, both in shyness and arousal.

they needed their release, they were quite aware of that. and they both knew that they wanted each other as well. it was really obvious at that point.

"are you sure?" donghyuck asked, looking at mark with so much care that it made mark's heart clench inside his chest.

"s-sure...?" he repeated.

"you want us to... to have sex...?" donghyuck questioned, his eyes never leaving mark.

"i want you donghyuck, please..." mark begged, almost tearing up.

"are you sure we won't regret it later?" donghyuck continued his questioning, wanting to make sure everything was okay before doing anything. mark was completely unexperienced in that field, and donghyuck was too. he had never had sex with a girl before, let alone a boy. he knew how stuff was supposed to happen, but he couldn't help but stress a bit.

"i don't care about regretting. i just want you. right. now." mark breathed out.

this was the signal for donghyuck to go on.

he jumped back on mark, their lips moulding together perfectly as their bodies tangled lovingly.

in a matter of minutes, both boys' trousers and boxers fell on the floor of donghyuck's room, and lube and a condom were pulled out of one of the room's drawers.

donghyuck lied down on his side, pulling mark in front of him.

"tell me if something's wrong, alright?" donghyuck asked, coating his fingers with lube.

"what could be- aghhh..."

mark moaned in the middle of his sentence, definitely not expecting for one of donghyuck's digits to penetrate his hole.

"does it hurt...?" donghyuck asked between kisses.

"n-no...ahh..." mark replied, his eyes rolling to the back of his head as donghyuck's finger curled inside of him.

"i'm adding another finger then." donghyuck declared, pressing another digit in and stretching mark's hole.

"ahhh..." mark whined, his back arching as his hands clawing donghyuck's bare back. "d-donghyuck..."

"you're so beautiful like that..." donghyuck simply said, attaching his lips to mark's neck to lick the virgin skin while his fingers went in and out of mark's hole at a rapid pace.

donghyuck finally added a third finger to make sure mark was stretched enough, and that the following events wouldn't hurt him as bad as it could.

mark was a moaning mess, arching his body into donghyuck's and scratching the skin of his back because of the amount of pleasure he was receiving.

it all felt so good... donghyuck's fingers were filling him up so well, and they were hitting all the perfect spots, making mark almost faint.

"m-more..." mark whined when donghyuck pulled his fingers out. "i-i want m-more..."

"wait a second, i'll give you what you want." donghyuck kissed mark's lips as he opened the condom and placed it on his neglected dick after giving it a few pumps.

once that was done, donghyuck lied on his back, pulling mark on top of his and making him straddle him.

"here, you want more...?" donghyuck asked, his hand roaming around mark's thigh while the other pumped his own dick.

"y-yes..." mark breathed out.

"then come here." donghyuck motioned to his throbbing member, making mark glance curiously at it before looking back at donghyuck.

"i-i... i don't know what to do..." mark admitted shyly.

"just sit down. i promise it will feel good." donghyuck said, holding his dick to align it with mark's entrance.

"i-i sit down? o-on it?" mark blinked confusedly.

"yeah." donghyuck gulped. "and fuck, don't look at me like that, i won't be able to hold myself back."

"is it going to hurt...?" mark started lowering himself, shivering when he felt the tip of donghyuck's dick against his clenching hole.

"perhaps a bit, but it is going to feel really good after." donghyuck replied, his hands gripping mark's sides to the point his knuckles became white.

"so, i just sit...?" mark looked down at donghyuck, flushing when he acknowledged the position they were in. he was about to have sex with donghyuck. he was about to lose his fucking virginity to donghyuck. and he felt so happy about it...

"when you feel ready, baby." donghyuck breathed out, forcing himself not to buckle his hips up to penetrate mark. he could feel mark's clenching hole against his tip, and he was so eager to feel him fully.

with a last glance to donghyuck, mark bit his lip and slowly lowered himself, sinking on donghyuck's dick.

"fuck..." donghyuck let out a long moan as his dick was engulfed by the tightness of mark's hole.

"aghhh!" mark exclaimed, feeling his body tearing apart. pearly drops left his eyes, crashing on donghyuck's bare chest.

"don't force yourself if it hurts..." donghyuck warned, his hands blocking mark from sitting further on his dick. he felt bad now to see mark crying because of pain.

"n-no, i want to do it..." mark sniffled, placing his hands on donghyuck's torso and sinking lower.

"but- oh, god..." donghyuck's eyes rolled to the back of his head as most of his dick had now been swallowed by mark's tight hole.

"ahh... please, don't move..." mark whined once he had fully sat on donghyuck's pelvis.

donghyuck nodded, his eyes closing to prevent himself from staring at how gorgeous mark looked right now, and then fucking him mercilessly – something he seemed to want doing.

mark waited for long seconds; his breathing ravaged as his hole got used to being filled so well. he used this time to stare at donghyuck, finding the boy so handsome naked under him.

his eyes were closed, and his breaths as irregular as mark's. the older boy could see donghyuck was holding himself. not only did he have his fingers dug into mark's sides, but he was also biting his lips harshly.

"y-you can move..." mark said after a while, making donghyuck open his eyes.

"oh, fuck... you look so hot..." donghyuck declared as soon as his eyes fell on mark's flushed body. "are you sure?"

"yes, please..." mark nodded, looking at donghyuck with puppy eyes. "make me feel good."

despite having made a silent promise to himself that he would be gentle on mark for their first sex, donghyuck couldn't help but jerk his hips up violently, making mark bounce on top of him and let out a loud moan.

the noises mark made were so beautiful, donghyuck couldn't hold himself anymore, and he used his hands to guide mark's hips up and down on his dick, making the boy above him moan louder.

"fuck... baby..." donghyuck growled, one of his hands reaching for mark's nape to pull the boy's face closer to his.

"aagh!" mark exclaimed as he fell on top of donghyuck's chest while his hole was being fucked so well by the younger boy.

one of donghyuck's hands wrapped around mark's waist, holding him firmly against his body to make sure he was hitting the right spots repeatedly, while the other cupped his cheeks and brought their faces closer into a sloppy kiss.

everything was messy, drool slipping out of their mouths as mark moaned in the kisses, his body jerking in every direction because of the strength donghyuck was using on him.

but he would never complain about it. it felt so good.

"aarrgh! right there!" mark yelled, his whole body spasming at a particular spot donghyuck had found, deep inside of him.

"don't worry about that, i won't stop, baby." donghyuck assured, going back to devouring mark's lips while slamming in and out of the boy at a rapid pace.

after a few thrusts, donghyuck flipped them over, making mark lie on his back on the bed while he was on top of him.

"oww! fuck!" mark yelled even louder as donghyuck ravaged that sweet spot inside of him.

donghyuck didn't slow down, thrusting in and out of mark and making sure to hit perfectly that little ball of nerves that was hidden deep inside mark.

he absolutely loved it. this whole having sex thing was a pure bliss for him.

even though donghyuck was usually someone who didn't seek for sexual release, mark had completely fucked up with his mind, making him hornier than ever. and he had to admit, he never expected having sex with mark to be this amazing and this incredible.

"d-donghyuck...!" new tears left mark's eyes, but judging by the way his hands were clawing donghyuck's back, and the way his face contorted with pleasure, his eyes rolling to the back of his head too frequently, donghyuck knew that they were tears of pleasure, rolling down his cheeks because of the overwhelming feeling.

"i-i'm... close... aghhh..." mark breathed out, burring his face into donghyuck's chest as the male above him didn't slow down.

"hold on for me, baby." donghyuck growled. "just a minute..." he added, feeling his release approaching.

the whole room was a moaning mess, mark's cries of pleasure and the sound of skin slapping being so loud that the neighbours would be able to hear. but neither donghyuck nor mark did care about that.

what was important was that they were loving this exact moment, their first time.

it was so good to both of them, and they were too focused on the euphoria of this very moment to care about what other people around would think about them.

what if mark was cheating on his girlfriend with her brother?

what if donghyuck was fucking his enemy?

what if they were doing something forbidden?

none of this mattered at the moment.

it was just mark and donghyuck, having sex – or making love.

both boys were pouring all their emotions into this escapade, finally letting out all the feelings that they had tried to burry down deep inside of them for the past week.

they were finally letting them out. they were finally letting the other in.

they had finally accepted that, as much as it was wrong, they were made for each other, and they needed each other to be happy.

"fuck, baby!" donghyuck moaned, his hip thrusts becoming sloppier as mark's hole clenched around his member.

"d-donghyuck...!" mark breathed out, his back arching in pleasure as he came, dirtying both himself and donghyuck.

"shit, i'm coming... aghhh..." donghyuck growled as his eyes rolled to the back of his head while he ejaculated inside the condom buried balls deep into mark's perfect body.

donghyuck fell on top of mark, forcing himself to roll to the side not to suffocate him.

both boys were panting hard, their hearts beating erratically inside their chests and their brains being completely out of it, still clouded by the extasy of their love session.

"ahh...!" mark exclaimed tiredly as donghyuck pulled out of his hole, making it clench a few times over nothing. it felt weird not to be filled anymore. mark found it better when donghyuck's dick was inside.

"sorry, baby..." donghyuck mumbled, pulling the condom away and tying it in a knot before throwing it in the direction of his bin.

donghyuck then turned around, wrapping his arms around mark's body and pulling him closer while the older boy cuddled into his chest.

"it was... amazing..." mark declared, his eyelids feeling heavy as he lifted his head to look at donghyuck.

"it truly was..." the other chuckled, leaning forwards to kiss mark's lips.

their kiss wasn't dirty for once.

it was simple, gentle and... full of love.

donghyuck's lips moved slowly against mark's, pulling his body even closer as mark melted completely into donghyuck's hold.

it felt so good... so warm... so perfect...

they pulled out after a few seconds, cuddling back into each other's embrace lovingly.

"it's so sticky..." mark whined tiredly, looking at his and donghyuck's tummies on which his own semen was slowly drying.

"i'll clean us up, don't worry." donghyuck chuckled at mark's adorable behaviour.

"mmkay..." mark smiled, his eyes fluttering close in tiredness.

donghyuck stared at the boy in his arms, admiring his oh-so-beautiful features.

mark was perfect, for real. donghyuck couldn't even understand why he was so mad at him for that. there was no use trying to prove the contrary. mark was the most perfect person existing on this earth. and he was... dahyun's.

donghyuck sighed, one of his hands reaching for mark's blonde hair to push them away from his ethereal face. mark snored lightly, sleep taking over him easily after the exhausting activity they both had done.

"god... you're such a perfect boy..." donghyuck mumbled, his eyes never leaving mark. "no wonder i have fallen for your charms..." he added, kissing the boy's forehead. "i love you, mark lee... but sadly, you're not mine... you have a girlfriend of your own... and we'll never be able to be together... even if we wanted to... because you're so perfect that my sister will realise it; and when she will, she'll keep you for herself, forever... so, i'll be stuck admiring you from afar... but that's a pity, because i would love holding you into my arms and screaming to the world that you are mine and mine only..."

sadly, things never went according to plans...

donghyuck's plan had failed miserably as he had fallen for his sister's boyfriend.

it was so wrong...

how could he even imagine hurting mark?

and how could he do that to his own sister?

all of this was so freaking wrong. donghyuck's friends were right since the beginning.

and as much as donghyuck hated to do this, he would need to apologise to them and ask them help, because he had no clue what to do now...
