The front door slams shut, “Mom, I’m home!” Jay called, excited that summer break is finally here. Backpack slung over a shoulder, kicking off his sneakers. His mom’s voice floated from the kitchen—

 

“Jay, come meet your Uncle Mingyu. He’s staying with us for a few months.”

 

“What?” Jay frowned, trudging into the living room. The last thing he needed was some relative invading his space. “Uncle who—?”

 

“Hey, kid!” Mingyu stood by the couch, grinning as he offered a handshake. “You must be Jay!”

 

The man was tall and very broad, with muscles practically bursting through his white tee, which complemented his tan skin and exuded golden retriever energy.

 

Jay gave him a once-over, trying to hide his surprise. This guy was supposed to be his uncle? No one had warned him he’d look like he just stepped out of a Men’s Health magazine. “Yeah, I’m Jay,” he reluctantly shook his hand, suppressing the flush creeping up his neck.

 

“Welcome, I guess… So, uh, I’ll be in my room.” Jay smiled awkwardly and sprinted up the stairs.

 

“That went well.”

 

“Oh, you’ll get used to him,” Mrs. Park beamed.

 

“Good to know we’re off to a great start.” Mingyu glanced at the second floor, a twinkle in his eye.

Mingyu settled in quickly, as he had always been a part of the household. Jay found him playing guitar on the patio occasionally, just like he did. Most days, Mingyu helped out in the kitchen. Mrs. Park even complimented him for his cooking, which annoyed Jay since she had never given him any. But the most annoying part is how his uncle charmed every neighbor. They would get random knocks on the front door, receiving casseroles and random treats. Never in their many years living in this place did they get this treatment until his uncle came into the picture. Mingyu had that magnetic energy that Jay found—irritatingly charming. Jay hated that he, too, struggled to keep his distance.

 

One evening, Jay was in the kitchen, rummaging for a snack. Not even a second later, Mingyu walked in, fresh from a late afternoon run. Tank top soaked and clinging to his chest. Skin glistening with sweat and appearing so irresistible. Jay knew the neighbors had a field day each time his uncle jogged past their houses. I mean, look at those scrumptious muscles!

 

Jay did not notice that his eyes were flickering all over the sharp contours of Mingyu’s abs. When he realized where he was staring, he quickly averted his gaze.

 

“You good?” Mingyu asked, grabbing a water bottle from the fridge. He unscrewed the cap and tipped his head back to drink, Adam’s apple bobbing with every swallow, like a friggin’ Evian commercial.

 

“I’m fine. Why wouldn’t I be?” Jay busied himself with the bag of chips in his hands.

 

“You look like you saw a ghost,” Mingyu teased with a smile, walked over, and leaned against the counter, towering over Jay. “Or… Was it something else?”

 

“Tsk. You wish,” Jay rolled his eyes. “You’re not that impressive.”

 

A brief pause

 

“Sure, kid,” Mingyu said, keeping Jay caged in his strong arms. His grin did not waver. "If you want to join me for a run, just say the word.” He then gave his nephew a knowing glance and left.

 

“Hard pass.” Jay scoffed audibly. He heard Mingyu’s sarcastic laugh echoing in the hall. He wanted to be annoyed but felt all giggly inside instead.

Jay casually strolled into the living room the next day and instantly froze. “What the!” Mingyu had just finished a workout, and every bit of detail in front of him was sinful. “Does he pump mass every day?” Jay thought. Not that he’s complaining—his uncle was a major eye candy.

 

Mingyu stood shirtless, tan skin damp with sweat; the golden light streaming through the window highlighted each hill and trench of his majestic physique. Massive chest, defined abs, and those hulking guns were all carved to perfection—the stupid MOFO even flexed as he wiped his face with a towel. Mingyu was a friggin’ full-course meal. Once again, Jay was captivated, throat dry, now eyeing the giant crotch bulge.

 

“What’s up, Jay? Need something?” Mingyu utters in a playful tone.

 

Jay fumbled with a bottle of Gatorade, “No, uh, j-just... Thirsty.” He mentally kicked himself when he took a swig at Mingyu’s energy drink. “You moron. First, you take his drink. Second, 'Thirsty?' Could you be more obvious?”

 

Mingyu chuckles, still sounding so adorable and manly. “Alright. If you want to tag along, feel free to ask. Workouts are better with a buddy,” he winked and sauntered off, leaving Jay standing there, heart pounding.

That night, Jay’s mind was consumed with images of Mingyu. Under the shower, he replayed the kitchen and living room scene over and over. “Why does he have to be so sweet, caring, and hot?” his hand drifted below, imagining how the drops of sweat trail down the cuts of his uncle’s perfect body. Jay’s breaths quickened along with the firm strokes—

 

“I wonder what would it feel like if he sucks me off?”

“He’s big everywhere. How big would his dick be?”

“Would he fuck me if I showed him my dirty hole?”

 

He bit his lip, suppressing a moan, and came (a lot) on the tiled wall with Mingyu’s name slipping out. The guilt that followed did nothing to dampen his desire. Instead, this occurrence became a nightly ritual, leaving Jay more flustered, frustrated, and painfully erect even after he finished.

 

Will he be able to have the real thing? Summer is almost over, and Mingyu only has over four weeks left. What should he do?

A few days later, Mrs. Park asked Jay to hang a new picture frame. She mentioned a girl named “Somi,” Mingyu’s 'lady friend,' something about her coming over or whatever. Jay didn’t pay much attention to it.

 

So here he was, on a step stool ladder, adjusting a frame when he sensed a prickle of awareness. Thinking he was all alone, Jay glanced over his shoulder and caught Mingyu checking out his—ass? It was fast, almost unnoticeable, but his pulse spiked.

 

“Did he just…? No. He’s probably just zoning out." But the thought lingered, fueling a dangerous combination of hope and confusion.

 

News flash: Jay is very much aware that he is packing a dump truck behind. His best mates, Heeseung, Sunghoon, and Jake, would always make jokes about it. Saying that if Jay were a girl, they’d have a piece.

 

“Need help?” Mingyu’s voice brought Jay back to reality.

 

“No, I, um, I-I’ve got it,” Jay replied in a jiffy. Nerves are evident in his tone.

 

“Sure? I don’t mind lending a hand.” Mingyu stepped closer anyway, studying the placement, his 57cm shoulder width encasing Jay. “You’ve got a good eye for balance, though. The frame looks perfect.”

 

Jay’s heart fluttered at the unexpected compliment from his crush uncle. “Uh, thanks,” he mumbled, hurrying to finish. As Mingyu walked away, he ogled at the older man’s Dorito-shaped back, how the solid lats taper to a firm waist and perky buns. Mingyu is most certainly a sculpture that came to life. His cheeks burned at the thought, and he swiftly returned to his task.

 

 

Around 8 p.m., Jay's mom was still out with her friends. He was pacing in his private chamber, formulating tactics to advance his relationship with Mingyu when the door beside his bedroom closed. “What’s going on?”   Sounds of giggles and furniture fumbling followed. Curious, Jay pressed his ear against the wall. He heard faint whispers and flirting. Minutes in, a woman started moaning and cussing until they became high-pitched.

 

“Is that Somi?” Jay was infuriated. Perhaps this was his uncle’s special friend or… Girlfriend? Realizing that maybe this was the reason why Mingyu went to the US. He wanted to get angry with every fiber in his body, but Mingyu’s deep, masculine grunts sent him spiraling. Each sound was a reminder of what he couldn’t have.

 

This instance was the first time he heard Mingyu’s pleasurable noises. Jay’s nether regions heated up rapidly as his upper back rested against the wall, listening to the progressive coital resonances, doing his best to shut off Somi’s bothersome squirms. Jay frees his raging boner, spits in his hand, and strokes himself in time with Mingyu’s obscene grunts.

 

It was reckless and wrong, but he couldn’t stop.

 

Jay got lost in jerking off that his moans crescendo. “Fuck me, uncle, make me cum on your big cock!” Mingyu’s name spewed from his lips again and again. Squeezing his nuts when he came, barely biting back a cry, the initial ropes splatter on the floor, and the rest oozes down the grooves of his knuckles and fingers to his ball sack. “Fuck,” he hisses, guilt and longing crash over him in equal measure.

 

He stumbled to his bathroom to shower off his 'shame.' Things were getting out of hand—pun intended. But no matter how hard he tried, he couldn’t shake his obsession. That was proven true when Somi returned every night for that entire week. Though he hated hearing how much she loved it , Jay boldly jerked off to Mingyu’s delicious noises each time. Imagining he was responsible for giving him that much pleasure.

 

He is hooked. Mingyu was a storm, and Jay was caught in its relentless pull.
