When school started, Ainsley relented on the diaper restriction. “You don’t have to wear ‘em to school babe.”

Claudia shrugged. “I should. What if I have an accident? Besides, I kind of... I kind of like it. It makes me feel protected, like you’re always there.”

So Claudia Kate Thomas started wearing diapers all the time, including at school. At first she was nervous about it. Surely someone would notice? But no one said anything and she became more comfortable.

Claudia and Ainsley didn’t share any classes this semester, but Ainsley was taking Algebra, a class Claudia had aced without even trying real hard and so there was plenty of material for tutoring.

It was Thursday evening of the first week of school. They were at Claudia’s house because her parents were out at dinner and probably wouldn’t be home until real late. Claudia had peed her diaper as soon as they’d gotten home. She looked at the floor and blushed and that was all Ainsley needed.

There was a routine now. Ainsley would put a pillow on the floor and position Claudia into lying on her back with her head on the pillow. Then she’d strip her from the waist down, clean her up with wipes, dry her off with powder and put on the clean diaper. Sometimes she’d give Claudia a few light spanks just to tease her. Claudia never objected, just squeaked and wiggled.

After the changing, Claudia went in only her shirt and diaper.

Then it was time for studying and for nearly half an hour, they managed to get through the algebra notes without complaint. But then, as every night before, Ainsley slammed her book shut and stood up.

“Time for a break,” she declaired.

Claudia frowned. “Ainsley, you’ve got a test tomorrow. You’ve got to get this down.”

Ainsley shrugged. “It’s stupid to have a test the first week of the semester anyway. I’m done for tonight.”

“No,” objected Claudia, “Not this time Ainsley.”

Ainsley fixed her friend with a look. “What?”

“You can’t continue to slack off your school work. You could have gotten an A in French, but you didn’t study enough.”

“I got a B+,” objected Ainsley.

“And a C in every other class. I could have helped but you didn’t want to. Said it was boring.”

“It was boring.”

“Ainsley, that’s enough. I can tutor you or not, but if I am, you’ve got to study when I say so.”

Ainsley put her hands on her hips. “Is that so? Let’s not forget whose the baby here.”

Claudia blushed but didn’t back down. “I may be the baby in the diaper, but you’re the baby with homework. And if you don’t get your butt back in the chair, I’m going to spank you silly.”

Ainsley gasped. “You wouldn’t.”

There was no more discussion after that. Ainsley objected of course but in a few moments found herself stripped from the waist down and lying tummy down on Claudia’s bed.

“Claudia, no, please, I’m sorry, I’ll study, don’t spank me, pleeeassss... owie!”

The red haired girl’s palm had smacked soundly onto Ainsley’s naked little bottom and she began to wiggle and squirm and kick as it made repeat visits quickly and sharply.

“No, no, no, no, no...” Ainsley moaned.

“I’m sorry baby,” said the diapered girl, “But this is for your own good. I won’t allow you to throw away your academics.”

“Okay, okay, you’re right!” wailed Ainsley before breaking down into sobs.

Ainsley was made to stand in the corner, stripped of all her clothes, with her hands on her head, as she wound down from her spanking induced sobbing. About twenty minutes later, she found herself shifting uncomfortably on the hard wooden chair at Claudia’s desk.

Later that night, as the two girls lay under the covers of Claudia’s bed, cuddled close together, Ainsley whispered, “Are you awake?”

“Yeah,” Claudia whispered back.

“I’m sorry. About what I said. I mean, you have to do what I say with the diapers but...”

“It’s okay,” replied Claudia. “I know you didn’t mean any harm.”

“Good.” Ainsley squeezed Claudia tight and kissed her shoulder. A few minutes later she whispered, “And thanks for... for the spanking. I needed that.”

“I’d do anything for you, remember?”

Ainsley rubbed her bottom gently. “I sure do.”
