He can't risk another attempt

Ok, you win," says Adam says grudgingly. "Isla caught me. There's no way I'm going back."

Nathalie grins and shuts her book with a loud clap.

"I knew it! I knew you'd pussy out."

She looks over at the bed. Adam's eyes follow. The school uniform is neatly laid out there - a short plaid dress with white collars, knee high white socks, a tie, and a pair of baby blue panties and a bra.

He's not much bigger than Nathalie, and she was wearing the dress to school only recently. He has no doubt that it'll fit.

He feels his mouth go dry. Nathalie can't keep the smile off her face.

"Such an imaginative and humiliating punishment! I don't know how you thought it up."

She stretches and yawns dramatically.

"Although, I'm a bit too tired to give you a spanking right now. And I don't think this is quite the location for it either. It should be in your bedroom, really, not mine."

Adam pales. "You can't mean...?"

"When do you want it, big boy?"

Adam's heart is racing as he thinks. His parents are out at the weekend, and his sister Cassie is staying over at a friend's.

"Saturday," he says weakly. "Saturday afternoon."

"Fine," she says. "See you then."

He turns to leave, crestfallen.

"Aren't you forgetting something...? Nathalie asks tartly.

Face flushing, he goes to the bed and scoops Nathalie's old school uniform into a bag. The panties feel soft to the touch and he knows his face must be bright red.

"See you Saturday," Nathalie says sweetly.
