Blast from the Past - coming tomorrow

Tomorrow, I'm going to release this month's 'blast from the past', where I look back at a classic Sebtomato tale. 

Here's an excerpt - see if you can tell which story it is :)

“What are you looking for?” Steve gave his phone one last check, made a grunt of irritation, and then put it on the dressing table.

“Hang on…” Carly dug around at the back of her wardrobe and then gave a muffled shout of triumph. “Here’s a pair!”

“What?” Steve muttered. He rubbed his eyes, and then opened them to find Carly had kicked off her shoes and pulled on a pair of white knee socks.

Steve’s eyes widened. “What…whatcha doing?”

“Next best thing,” Carly said, sitting at her dressing table with a grin on her face as she arranged her hair into two bunches. She twisted off the stool and stood in front of Steve, her hands clasped in front of her. “How do I look?”

“Ummm..” Steve started. “Cute?”

Am I only dreaming?

Carly beamed. “I can’t wear the dress ‘cause it’s way too small, but the socks are fine and I can still do my hair the proper way.”

Steve gave her a cool look. “That’s called teasing. And it’s not nice.”

Carly shook her head, a confused expression on her face. “I thought maybe we could have some fun.”

“But two seconds ago you were…what?” Steve looked into Carly’s face, as if trying to decipher her true intentions.

Carly nodded, her pigtails jiggling. and then she blushed, giving Steve a strangely shy and nervous glance.

Steve patted the bed. “Okay, sure.”

Carly giggles and jumped onto the bed, going on all fours around him and then lying down on the side nearest the wall. She lay straight, like a board, and looked up at him with an expression of great anticipation. She bit her lip. “You’ll have to show me what to do. I’m just an innocent schoolgirl, after all.”
