@jiduckz has been murdering me with fic prompts and i haven't been able to stop thinking about this
+ size difference and mirror sex so !! ohonsu drabble time 🥰
As much as he himself denied it, everyone knew Jiseok was small. He was so easy to manhandle that the other's just couldn't help themselves—using any excuse to touch and tease and pull him close to their own bodies. Being able to lift him like he weighed nothing was a favourite for one of them in particular.
Even though Seungmin had been significantly less strong when they'd filmed the episode of RTW, Jiseok had still been lifted from the ground without much effort despite the awkward way he'd been crouching, and it might not have been the sole reason for him to start taking working out more seriously, but it definitely contributed to it. It was a little too inspiring.
Seungmin was already into mirror sex—enjoyed watching himself and whoever he was with lost in each other more than anything else—so it only made sense to try something similar that way too. It still took a while to get to the point where it wouldn't be too much strain on his muscles to hold Jiseok up, leaning back against a wall with his hands beneath Jiseok's knees instead of curled into a ball, but they made it work. Jungsu getting involved changed things slightly.
Jiseok was tiny. That didn't mean he couldn't take more than one of them at a time.
He'd gotten as used to being suspended like that by Seungmin as he possibly could be, and it wasn't like Jiseok had never done it before in 'normal' ways, but sandwiched between him and Jungsu was entirely different. They put a mirror to the side to catch everything they could—Jiseok's legs being spread wide as he was lowered onto Seungmin's dick not something they wanted to miss—and it was almost too much to watch even before Jungsu stepped closer.
Jungsu always acted like whoever he was with would shatter if he wasn't ridiculously gentle. Maybe it was just because he'd already made sure Jiseok was stretched enough or the whole thing was getting to him more than usual, but Jungsu braced himself on the wall by Seungmin's head and pushed inside faster than expected, leaving Jiseok scrabbling at his shoulders and panting against Seungmin's neck with his eyes screwed shut.
Seungmin's fingers tightening was more painful than the sudden extra fullness even if Jiseok appeared too tiny to take it. Jungsu went still anyway, waiting for their breathing to steady before drawing his hips back, but Jiseok started whining pathetically seconds later. He squirmed in Seungmin's hold—overwhelmed by being surrounded by their bigger bodies without being able to move. Too much.
"Good. So good," Seungmin's voice cut through the fog. "Look."
It was difficult, but Jiseok’s eyes fluttered open to refocus on the mirror. He regretted it immediately. The two of them usually softened their features with wide smiles. In the reflection they appeared sharper, so intense it was almost frightening, not at all helped by them already staring at him. That was somehow even worse than seeing just how small he was in comparison. With the mirror being to their side, not everything was visible, and Jiseok was too afraid to look down at his stomach with the feeling that there had to be a visible bulge.
Dizziness forced Jiseok’s head to loll back onto Seungmin's shoulder heavily. He was aware that he was close, but he couldn't bear to touch himself. Jiseok still felt the tightening in his stomach, breathy moans turning frantic, realising too late that he was going to come untouched. Digging his nails into Jungsu's shoulders, Jiseok wailed as his come hit his chest, not registering that the other two had stopped moving and pulled out until he was placed on Seungmin's bed.
He had no idea how much time had passed, but being cleaned up and squished between them that way was more comforting than overwhelming, and Jiseok was happy to stay.
