A "sweater dress"

Brandi walked into the class feeling ridiculous. The only items she'd found in her gym bag were her favorite oversized loose knit sweater, her knee-high leather high-heeled boots, and a broad belt. No pants, no skirt, no underwear. She swore she was going to kill Amy when she got home.

The sweater was normally long enough to come almost to her mid-thighs, which is why she liked to wear it with leggings. But the belt tied around her waist did three things: It made it look more like a sweater dress (which was good), it pulled the top tighter against her chest (which was bad), and it shortened the bottom by a good 3 inches (which was very bad).

She had considered keeping her thong on from her workout clothes, but, even if that hadn't been cheating (which might get her a permanent dare) she had sweat too much in her workout to consider rewearing anything from that outfit.

The problem with the sweater wasn't just that it was short (although that made Brandi very nervous), it was that the knit was loose enough that anyone looking closely enough could see that she wasn't wearing any underwear. Sometimes, when she wasn't careful, a nipple (both of which were surprisingly erect--was this outfit turning her on?) would poke out through one of the gaps in the knit. She was glad she'd waxed recently or she was sure her pubic hair would do the same.

She looked nervously around the classroom, everyone was looking at her, but she told herself that it was because the boots and "dress" made her look unusually dressed up. The classroom had stadium seating--so if she sat in the front, her teacher would be able to see her up close, but if she sat in the back, the view up her "dress" would be at about eye level. Eventually she decided on the middle, behind someone tall.

The teacher, middle-aged woman with a short hair (who definitely triggered Brandi's gaydar), started lecturing on macro-nutrients, and Brandi adjusted her sweater again to conceal a pokey nipple, when she heard her phone vibrate in her purse.

She pulled it out and surreptitiously took a glance. She noticed she'd missed a message from Stace this morning--she opened it to see the first of Stace's sexy selfies. She smiled and felt a thrill of arousal as she thought about the fact that Stace would have to top that picture tomorrow.

The second message, the one sent right now, was a dare from one of her friends.

She must have gasped when she read it, because the Ms. Trunton suddenly noticed her.

"Brandi, why are you on your phone in my class!"
