Eighteen year old Glen Deaning stuck his head into the hallway and called out, "Has anyone seen my baseball uniform!?"

From downstairs in the living room, Dean's brother Carl called back, "Yeah I saw it hanging in the basement!" From up above Carl could hear Dean's footsteps as he ran down the hall and the descended the stairs. Carl was sitting on the sofa eating a bowl of cereal and watching ESPN when Glen appeared at the foot of the stairs, clad only in a ridiculously small pair of leopard print bikini briefs.

"Woah! Little Brother!" said nineteen year old Carl. "What the hell are you wearing?"

"They're my lucky briefs," replied Glen looking down at his lean, well defined, muscular body.

"Looks more like an eye patch to me," retorted Carl, who, in comparison to his brother, was fully clothed in gray sweat pants and a bright royal blue T-shirt.

"Ha. Ha. Very funny," snapped Glen. "These are the underwear Jeannie bought for me the first time we fucked. She said she saw 'em and thought my ass would look hot in 'em. Unfortunately she didn't know my size and they are a little too small, but they brought me luck that night with her so ever since then every time I have something big coming up, I wear them. I guess you could say they're my "lucky" underpants."

"Those things are way too small to be called "pants" of any kind," replied Carl.

It was a fact--the underwear that Glen wore were way too small and tight for his build. Glen was by no means fat. He was lean and well defined. However, no matter what he did he couldn't lose his ass. In fact, it just seemed to get larger and larger. It was perfectly round and stuck out far in back, giving a sexy shelf appearance that the ladies loved. Not to mention some of the guys. Plus it had just the right mixture of firmness, yet still had some jiggle and bounce. On top of this, Glen resembled a teenaged Dean Cain, so he was quite the ladies man.

"Again! Ha. Ha," Glen replied as he turned his back to his brother and made his way toward the basement.

"Holy, SHIT!" exclaimed Carl and he got a look at his younger brother from behind. If the briefs were small from the front, they were minuscule from behind. The sheer size of Glen's backside and the smallness of the undergarment made Glen's ass appear to be twice as large and round as it was. And that was saying something.

"What?" asked glen looking back over his shoulder.

"Nothing," said Carl. "It's just well…I always knew you had a fat ass but in those briefs it looks even more enormous--if that's possible. I mean, hell, at least 3/4 of your ass is hanging out the back there."

Glen looked over his shoulder and down at his ass, which from his vantage point appeared to balloon out in back. Then he backed up a few steps toward his brother and bent slightly at the waist shoving his big butt melons in Carl's face.

He then ran his hand seductively along his meaty cheek and then gave it a quick slap. Then jokingly asked, "You checkin' out my ass, Bro? You turning queer on me?"

Carl reached out and pushed Glen's ass, his fleshy buttocks were warm to the touch. "Fuck
