He says yes

He wanted to say no to his twin, but he knew Raph, or well, knew what he was capable of doing, if this was his first dare, which was usually the most calm out of them all, he knew he would only come up with weirder amd weirder dares, and Leo wanted to save his No for a dare that either got him arrested for public indecency, expelled or suspended, or even worse, a dare that made him commit ****. He sighed in defeat.

"No no, I'll do it. I'm saving my no"

Raph grinned wickedly as he saw the way Leo took off his clothes, folding them neatly before laying them on top of each other in order of putting on, at the very bottom, his shirt, and at the top, his underwear.

"Really? Space heroes briefs? I thought you grew out of them at 12"

"They're comfortable!" Leo defended himself, his hands covering his dick as he made his way up the stairs.

Raph walked behind him, letting out a wolf whistle.

"Damn Leo, where do you hide all that ass? If you weren't so prudish I bet everyone would tap that"

"Not something you ever tell a sibling"

"And cleaning their bedroom while naked is something you do for a sibling?"

Leo blushed.

"You dared me to!"

"And you could said no" Raph grinned.

Leo, realizing he was trapped between a rock and a hard place, shut up.
