Chapter Text
Jimin was grateful that Yoongi had let him live with him, despite a few strange house rules.
Their families were old friends, but Yoongi was a few years older, so when Jimin finally made his way to Seoul, Yoongi was already well established with a good career and life of his own.
Jimin felt a little out of place, but he was grateful that he didn't need to stress through apartment hunting on his limited student budget when the academic year had already begun. Yoongi's spare room wasn't large but it was big enough for him, a single bed, and a desk to cram at when he wasn't at the library or dance studio.
He could live there relatively cheaply as long as he did his share of the housework, but there was one rule Yoongi told him was strictly non-negotiable.
Every Saturday night, Jimin wasn't allowed near the apartment between the hours of 5pm-1am.
Was it a producer thing? Maybe he didn't like people getting in the way of his personal projects, or maybe it was a day where he did self care? Jimin was so curious but Yoongi wouldn't budge on it, and didn't provide any further details.
Either he agreed, or good luck finding another place in the city on his budget.
So Jimin agreed, and he stopped asking questions.
They went about their lives, cohabiting together mostly peacefully. The questions that had originally burned a hole in Jimin's tongue slowly fizzled out, and going out every weekend became routine.
Until one Saturday night.
He was a little tipsy when Taehyung waved him out of the taxi after a campus party, that kind of drunk where he had come down enough to be just a little slow, a little mellow.
Taehyung offered to see him in but he didn't want to wake Yoongi, so he was being very quiet, as sneaky as a half drunk person can be, not letting his keys rattle against the door.
Whatever small noises escaped Jimin's notice didn't matter much anyway, as it became clear that Yoongi's focus was elsewhere.
It was only just after 11pm.
Jimin realised too late as he heard a high pitched voice.
Oh shit. Yoongi had company.
He pulled his phone from his pocket and quickly checked the time, but what could he do? He'd had a box of beers and had been dancing for hours, he was busting to pee. There was nowhere else to go, and he couldn't wait outside for two hours.
He heard another noise then, this time clearer in the quiet of the entrance way.
Jimin's whole body froze as the woman's moan came around the corner, ringing in the open plan of the apartment.
He couldn't stay, but he couldn't leave either.
Sliding the lock back again would make too much noise, Yoongi would know he was there.
"I thought you were going to be good," came his roommate's low voice.
He thought that he'd been caught before he realised that Yoongi wasn't talking to him.
There was a sharp slap, accompanied by another breathless moan.
Jimin had plastered himself to the wall of the entrance way, the only thing that was keeping him upright in his current state.
Was this what Yoongi needed Saturdays for? Sex?
Jimin didn't know why he couldn't just use his bedroom, he could have put a sock on the door or something, and Jimin could have worn headphones to drown out the noise and given him a little privacy.
He had the master bedroom, a much bigger space than Jimin's room. Why did he need the rest of the house?
Jimin's fuzzy thoughts took a while to piece it together, but he slowly came to a realisation as the sounds continued.
Taunt. Slap. Moan. And something that sounded very wet .
It wasn't just regular sex.
As the initial shock wore off, Jimin could feel his cock chubbing up at the condescending words falling from Yoongi's lips.
His small pink mouth was set in a sneer that shouldn't be so hot.
Jimin's mouth dried up as he watched from the shadows of the entrance way.
The sounds alone were enough to bring him to full thickness, the woman's cries echoing in the apartment, and he finally understood why he couldn't have just hid in his room.
The living room could have belonged in another house, that was how much had changed.
If he could focus on anything else, he may have noticed a familiar house plant, the same flat screen on the wall, where he and Yoongi watched their movie marathons, but his focus was elsewhere.
Yoongi stood behind a beautiful woman, her dark hair plaited down her back, and her bare ass exposed to the air.
She was on her hands and knees on a leather cushioned table Jimin hadn't seen before. She was naked beneath a mosaic of black silk ropes, binding her arms and ankles to the table so she couldn't move far from her almost downward dog position.
Her breasts were framed by more silk, nipples hard and exposed to the air, brushing against the surface of the table with every small struggle.
Yoongi wore a pair of dark silk boxers, his pale skin clear in the dimmed lights of the living room. Jimin had seen him wearing similar things before, but this time, his presence was completely changed.
"Oppa..." the woman cried, real tears slipping down her face and leaving tracks of mascara, and Jimin realised what Yoongi was doing behind her.
Jimin saw the next movement of his hand as he thrust a silicone dildo back inside, but he kept it shallow, enough to tease and feed her desperation. He could hear the wet glide even from there, as whatever she was trying to say dissolved into whimpers.
Those sounds easily penetrated the apartment’s thin walls.
"Use your words," Yoongi ordered bluntly.
His voice was almost empty of emotion, just an edge of teasing cruelty, enough to send a shiver over Jimin's body.
"Ah, ah, more, please," she panted. "Need more."
"You want to come already? Before you've even pleasured me?" he tsked. "You're so selfish, baby."
She shook her head frantically but didn't deny it. "Want- want your cock, Oppa," she gasped out, almost drooling as she rocked back against the dildo, but Yoongi held it too far back. Her body only swallowed the tip as she wriggled back in frustration.
He laughed, and Jimin stared in awe at the power in the short sound. "Do you think you deserve my cock? Have you been a good girl?"
"Oppa.. " she babbled, tugging at the black silk ropes in vain. They didn't budge. "P-please, Oppa, need you."
Jimin wanted to take her place.
Maybe it was the drinks, he'd had too many, or maybe the way he hadn't been satisfied sexually for so long. He wondered how long Yoongi had been teasing her to get her to that state.
He could do better than she could.
She didn't deserve his cock, but Jimin knew he could earn it.
He’d never considered anything like it, but he suddenly wanted to know what it felt like to be called Yoongi's good boy.
Without conscious thought, he palmed over the bulge in his pants, his other hand covering up the needy sounds that pooled in his mouth.
He shouldn't be watching, it was a breach of his friend's trust, but the sight was addictive.
As the woman's cries grew even needier, Yoongi suddenly pulled the dildo out with a wet pop and tossed it to the side as he dropped his shorts and lubed up his own cock.
Jimin stared from his hiding place.
Yoongi was big. Even from a distance he could tell, he was longer and thicker than Jimin's own cock, and he felt his ass clench in want. He’d been empty for so long.
The woman whined and shook her head, trying to turn to see him with her ass pushed up into the air, holes exposed.
"Shh, shh. Oppa's giving you more than you deserve, aren't you grateful, baby?" Yoongi said, rubbing a hand over the curve of her ass.
"Let's see, you've got two pretty holes for me..." he said casually, dragging his fingers down her crack. His hand paused, seeming to press lightly over her cunt for a moment. "Do you want me here?" he asked as he tried to push back on his fingers, forgetting her words again. His fingers dragged up a little, pressing over the tight bud of her asshole. "Hmm, or here?"
His cock stood at attention, thick and heavy in his other hand as if awaiting orders, but it was very clear exactly who was in charge.
Jimin felt like he was holding his breath, like it was his body Yoongi was touching and he was somehow having an out of body experience. Yoongi's voice was melodic, drifting over him in a way that could have put him to sleep if his body wasn't on fire.
The woman struggled against her restraints, trying to move her body just a little back, where it could welcome at least some part of him inside, but Yoongi only laughed.
"No answer? You've not even gagged, baby," he stepped back out of reach again, letting her whine and struggle as he watched from behind, slowly stroking his slippery cock.
Jimin didn't think he'd ever seen something so erotic.
"I know you'll take it in whatever hole you can get, but your ass isn't ready, is it, baby?" he clicked his tongue and she cringed. "You need more training before you can take me there," he said with another slap at her already red cheek.
She cried out needily, but 'Oppa' was already lining up the head of his cock where she couldn't see, smoothing his hand over her hip to grip it before he plunged in in one smooth thrust.
"Ahh!"
"That what you needed, baby girl?" he laughed, reaching up with his other hand to pull her plait back to expose her neck.
"Tha-th-ank you!" she said shakily.
From the side, Jimin could see the blissed out expression on her face, her eyes fluttering shut as her body shook with each rough thrust.
The new angle just made her cries louder, echoing through the house, each sound an insistent tug at Jimin's cock.
He brought a hand over it with a low whine as he watched Yoongi fall into a rhythm, feeling like his own body was taking the pounding as he slid bonelessly down the wall, his hole clenching around nothing as he felt a new spike of jealousy with every wet slap of ass and thighs.
Jimin watched Yoongi shift position then, one hand gripping beneath the woman's thigh, fingers digging into the flesh as he lifted her ass higher and pushed her back down until her breasts were squashed beneath her.
He held her firm, keeping her legs spread around him as her words became incomprehensible, a constant stream of sound.
Jimin lost track of how long he sat there.
He was still hazy enough that time didn't register well anyway, but from the way Yoongi fucked a few orgasms from the woman beneath him, he got the impression it was a while before he let himself feel his own release.
It was the hardest thing he'd ever done to slip quietly back down the hall and out of the apartment without making a sound. Cries of release chased him out into the night, the lower voice an erotic echo in his head.
The last image he'd seen was imprinted on the back of his eyelids.
Yoongi with his hips stuttering, spilling come all over the girl's back with a rough groan.
He wished he'd been able to see his face.
He still needed to pee, through his damn erection still going strong, but he'd rather sneak behind the back of their building and brave the chill night air than have to look Yoongi in the eye after what he'd just seen.
He had a terrible feeling that Yoongi would know just by looking at him.
After taking care of his business, Jimin found a place under the car park stairwell out of the wind, thankful he had kept track of his jacket all night.
He huddled for warmth, watching dance videos on his phone until it screamed its imminent death.
The apartment complex was quiet as 1am approached, the neighbourhood housing mostly older families and couples from what Jimin had seen in the last month.
Jimin's phone had died not long after midnight, but he thought it was around 12:45am when he heard a door open above, and steps on the stairs.
He retreated further into the shadows beneath the stairwell, feeling like a criminal as he watched Yoongi murmur something in the woman's ear when they stopped next to what must be her car.
She smiled shyly, still looking blissed out as he kept a hand on her waist. She looked sweet with clothes on, and Jimin felt a delayed twinge of guilt for seeing her naked without permission.
"Are you sure you're okay to drive?" he asked softly, tucking a strand of hair behind her ear.
She nodded, looking up at him with big eyes. "Thank you, Oppa."
He brought his hands up, holding either side of her face as he pressed a gentle kiss to her lips. He pulled away with a smile when she tried to follow.
"Anytime, baby."
Jimin waited a bit longer, creeping out of his hiding place once everything was quiet again. He was stiff from the cold, but at least his erection had gone down.
He snuck into the apartment, quiet now with the usual furniture back in place as if nothing had happened. It even smelled fresh, like Yoongi had had one of his scented candles burning.
Yoongi was nowhere to be seen, his bedroom door closed and the apartment dark. If Jimin had only just come in then, he would have had no idea what Yoongi needed the evening for, might have even grumbled to himself about it in his tipsy state.
But this time, his eyes were wide, as if searching for a clue that it had actually happened, that what he'd seen hadn't been some elaborate fever dream.
Even at his most delusional, he didn't think he could have created such detailed imagery.
As he passed through the living room, he pictured Yoongi's hand sliding over his thickly veined cock, the sound of his hips slapping against a firm ass.
He moved through the apartment quickly, hurrying to shower and change before rushing back to the safety of his room.
He lay awake for a long time, dreading what Yoongi might see on his face in the morning.
