Arousal

At first I couldn't tell what was happening inside me, but as Sarah pinches and pulls my nipple I recognize that I am feeling something that I really do not want to be feeling. Aroused. My nipples begin to harden and I can feel just a faint amount of wetness building up down below.

I now am slightly turned on. In class. While naked.

How the fuck am I getting turned on right now? I should be absolutely mortified! Well, I am, but somehow I am turned on at the same time! It must be the combination of the embarrassment of being naked in front of my peers, the slightly cold air, and the obvious fact that two of my friends are touching and grabbing my boobs and nips like it was totally normal!

Okay, I'm just a little turned on, that's it. I've been turned on in school before. Of course, that was in sex ed where we had a live naked dude who was quite cute. Oh, and you know, I was wearing clothes!

Hopefully no one notices. By the way, where the fuck is the teacher? It's like five minutes into class and the only thing these other kids are learning is what my boobs look like.

"Holy shit Em, are you turned on right now?" Allyson giggles, covering her mouth with her hand.

Fuck, they noticed.

"Wha- what?" I speak up, trying to pretend like I don't know what she's talking about.

"Oh my god, you totally are! Your nips are hard as diamonds right now" Sarah says gleefully. Why are my friends so weird.

She's right though, my nipples are at full attention, sticking out like pencil erasers off my breast.

The rest of the class is either laughing, taking pictures or recording, or simply taking it all in. Even the girls in the class are enjoying the show.

"It's just cold in here, that's all!" I lie, hoping they'll buy it and stop.

"Whatever you say, Em" Sarah shrugs, continuing to play with my boob.

Suddenly we hear doorsteps right outside the door, indicating our teacher will be in the room in seconds!

Sarah and Allyson release their hold on my boobs and we all quickly take our seats. Now that the initial shock is somewhat fading, I realize that I've been completely uncovered this entire time! I move one arm across my chest and the other in front of my crotch as I sit down.

I look and see that Sarah is sitting directly to my left and Allyson is sitting directly to my right. This will be an interesting class. I then notice that Sarah still has my satchel. I curse under my breath, not only is the satchel my only semblance of clothes, but I actually need it for schoolwork as it contains all of my notes and books. I didn't show up naked just to show everyone my tits, I'd actually like to learn something!

I almost ask Sarah for my satchel, but hold my tongue as the English teacher walks in through the door.

"Sorry I'm late class, traffic was just terri-" he starts to apologize, before cutting himself off when he sees me sitting completely naked at my desk, with only my arms to protect my goods from his view.

"Uhm, that's an interesting choice of an outfit you got there, Emily." he says awkwardly, trying not to look directly at me. "Can't say I've ever had a student just waltz in here in the nude. Not that it's against the rules, but I am curious, why on Earth are you sitting naked in my class?" he asks curiously. All eyes in the room are on me.

"It's... it's a long story, sir." I manage to get out. I couldn't think of many situations more embarrassing than this one. Naked. In class. Ugh.

"I can imagine. Maybe you can share it with us another time, since we need to get going right away with our lesson. We don't have a full hour of class today, and it doesn't help that I'm late, so let's just get started. Everyone, please get out your notebooks so I can start the lecture." he instructs.

I keep my arms firmly placed over my privates. It's probably pointless, but I appreciate any cover I can get.

Of course, that doesn't last long.

"Emily, please get out your notebook. This is an important lesson so I don't want you to fall behind." the teacher says hurriedly.

I look at Sarah, who still has my satchel sitting under her desk. I try to get her attention.

"Psst. Sarah!" I whisper.

Sarah looks at me and smiles.

"Hey, how's it goin' naked girl?" Sarah says playfully.

"Could you hand me my satchel? It has all my notes in it." I whisper my request.

"Of course!" Sarah says, and picks up the satchel and is about to hand it to me when she suddenly withdrawals the bag and puts it on her lap.

"Wait, not so fast." Sarah says slyly. Why is everyone I know being so difficult? "I want something from you, first."

"What the fuck can I give you? I'm naked you idiot and I don't have anything!" I hiss.

"Oh silly, I don't want a 'thing', I want something else." she says with a smirk. "I'll give you your bag back if you...
