Finn laid stomach down on the couch in their home, lounging in nothing but a pair of his new tighty whities. He munched happily on a donut, stretching out and scratching his back he heard keys in the front door.
"Sup man," Puck said as he shut the front door behind himself, thumbing through bills. He paused just as he passed and looked at Finn relaxing in his undies. He laughed a bit at the sight, "Day off?"
Finn smiled as he polished off the rest of his donut in one big bite. "You know it, bro," Finn had smirked, craning his neck to look over at his friend.
With his best friend in such a perfect position to be wedgied mercilessly Puck had a hard time resisting especially with how fat his ass had gotten. In the past Finns briefs sort of sagged, shapeless around his rear, but now both cheeks fit tightly into them. Puck unwillingly licked his lips as he eyed the other teens jiggling glutes.
Finn fidgeted a bit as he grabbed a second donut, his butt shaking even more than before. His right leghole lifted and sunk between his massive cheeks prompting him to quickly fish it out. "Is it just me or do my undies look a lot tighter? They definitely feel like they are." He asked, snapping the tight waistband.
"Huh? What?" Puck realized he had been staring, distracted by Finns globes. He smiled, sitting on his buddies legs and lightly smacking his butt. "I hate to break it to you but I don't think it's the briefs that have gotten smaller, bubble butt."
Finn jumped as his rear was smacked, struggling to get out from under Puck. God, when did he get so strong? He couldn't even budge! "What does that mean?" He groaned, slightly embarrassed to be stuck.
Puck poked one cheek as Finn struggled. He loved this, overpowering Finn. And for some reason having complete access to his ass was kind of...nice. "It means someone's been eating too many donuts."
Finn continued to struggle under Puck's legs. "Agh, come on. I haven't gotten that out of shape."
"Then why are these threatening to thong up?" Puck was holding each leghole, snapping them against Finns butt and causing a bit of his ass to spill out. He really loved this now, toying with Finns briefs, poking his rear end.
"Threatening? Or is that you just waiting to wedgie me?" Finn fought again, losing his breathe as he fought his way out, still unsuccessful. "My butt isn't that big!"
Puck laughed, enjoying all of this way too much. "If a Puckerman tells you your ass is too big its too big."
Finn paused as he stopped squirming beneath Puck. "Seriously? Then... what do I do? Go to the gym? I've never been there..."
But did Puck really want it smaller? He had been mesmerized from the moment he got home and since he sat down he was touching it as if he had not shame, poking and pushing it. Maybe he was enjoying it a little too much. "The gym is a good idea," he decided as he stood up, wanting to get away before he said or did something he'd regret. "You need some work out clothes though."
"So you'll teach me how to workout? Sweet!" Finn exclaimed.
---GLEE---
Once at the gym Puck, wearing a pair of blue shorts and a black tank top, stretched out his legs. "Followed my advice and wore something comfortable right? Can use your full range of motion?"
Finn was wearing a pair of black nike shorts and nice white t-shirt that was in fact a bit too small for him now. He gave a slight squat and nodded, bringing himself back into a standing position. "I'm moving well and even wedgie free for once."
"Wedgie free until I get my hands on you." Puck teased. He then led his friend throughout the gym, teaching him how to use various types of equipment to work out the major parts of his body. "So when you're done with lifting I'd suggest the treadmill. Forty five minutes a day, 3 days a week and your junk the the trunk will be gone."
"So, we're gonna end with the treadmill?" A sweaty Finn flashed a smile, happy they were almost done. This was a lot harder than it looked. "Well, that's easy enough."
After they were finished Puck paused, looking around the somewhat empty gym and noticed a set of pull up bars in the corner. He stifled a chuckle as he got an idea, leading Finn over to them. "Maybe we should work on your upper body a little bit more before we call it a day. Think you can do some pull ups?"
"Hardly," Finn said. As he approached the bars he took a deep breath before leaping upwards and clinging to the bar, unable to even hold himself up, his grip already shaky. "Oh boy," He struggled.
"Let me help." And help Puck did, gripping either side of Finns shorts and tugging them down to reveal his sizeable assets. His now snug briefs seemed to have enjoyed the run, riding considerably high up. "Wedgie free huh?"
"Puck!" Finn looked down at his thick legs, his face red as he looked around to see if anyone saw. He dropped down to the floor amid a collection of stifled laughter, looking around at the few who had seen before pulling up his shorts. "What was that for?!"
"That look on your face!" Puck could hardly contain his laughter as Finn left in a huff, his ass shaking from side to side as he raced into the locker room.
"Come on, don't be mad." Puck called as he chased his best friend into the empty room. "It was funny!"
Finn frowned, not easily forgiving Puck. But his friend made the same face and shrugged. "Come on buddy, I'm sorry. Bring it in for hug?"
As Puck opened his arms up wide Finn stared, unmoving as he was unsure what to make of the sudden shift in his demeanor. But being the sweet, simply guy he was he quickly accepted the apology and went in for the hug. Puck screamed as he felt Finn lunge for his briefs and bring them high up his back. Puck screeched as he went to wedgie Finn in return. "Let go, dude!"
"You let go first!" Finn demanded, determined to put on a tough facade despite feeling like Puck was mere moments away from slicing him in two.
"Shit!" Puck cried out as his cartoon briefs started to stretch to their limit. It wasn't the wedgie that made him exclaim, hell he had given himself bigger wedgies when he was half asleep but with those wedgies came a certain...reaction.
Ordinarily Puck was attacked from behind, making it easier to bend forward and cup his manhood to hide just how much he was enjoying it. But now, bulge to bulge with Finn there was nothing stopping the two from engaging in an accidental sex act.
"Alright, alright!" Puck said as he jumped away and quickly turned around. "I need to shower."
He left a confused Finn alone as he trotted off with his deeply wedged underwear still up his ass.
