Heading for lost property

I followed Camilla out of the room, although I suppose it would have been more socially-acceptable for me to be topless than for her to be in her bra, but I don't think this occured to her. From my position behind her I could see the blue floral straps across the back, the garment was a bit small for her as it was on the loosest loops and these seemed to be strained. I wondered if her day was going to get any worse, maybe her bra would snap as well...

"Crap." Camilla came to a sudden halt in front of me and I bumped into her. "There's a PE lesson on the playground."

I looked over her shoulder, there was a few dozen kids being organised into a game of hockey right where we needed to go.

"We'll have to go the long way around." I said, "It takes us past a lot of rooms, though."

"Round past the French block?" Camilla turned to look. My eyes were drawn to her breasts, where a nipple was making its way out of her bra cup, the soft pink rising past the blue material. I felt my trousers tightening around my groin.

"Er, y... yes." I gulped. I couldn't tell her, then she would know I noticed, but could I leave her with her nipple on display?

"Okay, let's get going, then." Camilla sighed, she set off in the other direction and I followed her again. After a minute we reached a block of classrooms, all with windows we would have to get past.

"Crouch down." I suggested, and she and I dropped below the windowsills.

RIP!

"Oh, what was that?" Camilla groaned.
