Tim was excited, his older brother was going to have to whole day to play with him! Vince "Vinny" didn't have a lot of time these days since high school started, but he'd promised to set aside the day to play with his six year old brother. Their mom was going to do some paperwork in the office, so long as they didn't bother her, she would be done in an hour or two.
"We gonna play now Vinny?" Tim asked as his brother was putting away his cereal.
"Just a minute bud, I'll meet you outside."
Tim ran outside, looking around the yard for stuff to do, there was a playhouse, a sprinkler, and a sandbox, and a collection of balls in the corner next to the tree. That's when he smelled the funny smell.
(POV swap)
Vince had just finished washing his bowl when he got a funny feeling in his head, and didn't know what to do. But he immediately found that it didn't matter, he felt so happy! He heard some stomping, and his mom came out of the office, barefoot and chewing on her hair.
He waved at her, but she was too focused on her boobies once she noticed them. Then Vince remembered, his bother was outside! They could play together!
He ran outside, and saw his brother playing in the playhouse, giggling and yelling.
"Come on Vinny!"
Vinny smiled and followed him to the sandbox, where Tim began building a sandcastle, Vinny was stuffing the sand down his pants to carry a lot to Tim. And Tim laughed at the method that was used, but went along with it.
As they worked on their castle, Vinny noticed his pee-pee felt itchy, and he solved it how any toddler would; take off their pants. And he did just that, with Tim staring at him like he'd grown another head.
"Why you do that?" Tim asked his brother.
"They's itchy."
"It's not bad to be nakie?" Tim had never done it before, but had never seen anyone go outside nakie before.
"No." Vinny shook his head, "It feels good."
Tim decided that if his big brother was nakie (or at least partially), he could be too. So they both took off all their clothes, and played in the sandbox.
Then their mom came outside, also completely nakie, and turned on the sprinkler, and shrieked with joy at the water splashing her bare skin. Her sons looked at her, and then yelled "Mommy's nakie!" Before running around with each other in the sprinkler wearing nothing but smiles.
