Another idea

Anna: Fully Clothed: Feeling Daring

"I mean..." Anna started, causing her friend to perk up out of curiosity "...does it have to be a streak?" she asked, biting her lip a little.

"Yes, unless you have any bright ideas" Claire said, shrugging her shoulders "You are more than welcome to make suggestions"

"Well...there was this one thing..."

"Go ahead"

"It might be a little risky..."

"Well...don't be shy"

Anna took a deep breath, deciding just to go for it "I could go to class naked" she couldn't believe she'd said the words out loud.

"Wow"

"I know right?" Anna chuckled shyly.

"Clothes, in my bag, now, you're doing this" Claire said in a commanding tone.

"I...well...um..." Anna blushed beet red, realising she'd got herself into something she'd have a hard time getting out of "...I guess..."

She started undressing, shirt first, then her skirt, bra, panties...she left her shoes and thigh high socks on, mostly because she didn't want to get cold feet, no pun intended. But it was partly because of the effect...they looked kinda hot on her like that.

"Well Anna, naked in school...I'll see you in five minutes, if you leave me waiting you'll be spending a lot more time naked than you think" Claire chuckled as she made her way out of the bathroom, leaving Anna alone and almost completely naked.
