Sibling Rivalry

... time?

It was after Penny had brought home a rare bad grade, on a geography test. Mom and Dad were out and Penny was busy studying to avoid letting it happen again, making for a perfect time for Cornelia to have a little fun. Recalling Penny's promise to study the capitals of Europe so she'd be ready for the next quiz, a quick look in the world atlas she'd never even opened before was all Cornelia needed. "Think fast, sis - what's the capital of Germany?"

"Berlin," Penny recited without looking up.

"Nuh-uh! It's Hamburg."

"That's ridiculous! It was Bonn before reunification, now it's Berlin. It's never been Hamburg!"

"Like I should believe you, sis, when you got a C on the last test?"

"Screw you, Neeli."

"Don't talk to me like that!" But Cornelia had gotten just what she'd wanted. It was just a matter of waiting until Mom and Dad returned. Mom had studied in Germany in college, after all.

They returned less than ten minutes later. As soon as they were in the door, Penny asked, "Mom, tell Neeli what the capital of Germany is."

"Berlin."

Cornelia didn't miss a beat. "She thought it was Hamburg," she chortled.

As usual, Penny took the bait. She slammed her book shut and said, "No, Mom, she -"

At the time, Cornelia had turned tail and run upstairs, lest Mom take it out on her too or, worse, Penny managed to get the truth out. Now, she thrilled to the memory of her triumph, Penny crumpled in a pathetic little lump on the floor, crying. She'd only caught a glimpse of that, but it was enough to play over and over in her head until she felt her second orgasm coming on.

"Ohmygodohmygodohmygod! Yes!" She squeezed Eric's head so hard it hurt, but he didn't dare tell her that. "Faster!" she ordered, and he obeyed.

While Eric was serving his penance, Penny remained oblivious to just what she had inspired. Wishing she had some way of knowing if Joe had taken a look, she towelled off and retired to her room to dress. She had packed only casual clothes for the weekend, never imagining there'd be any cause to wear anything fancy. But she had (quite intentionally) left a yellow and green dress in the closet last year that she didn't care for. She still didn't care for it, but it was by far the most appropriate date outfit available, and it still fit over her favorite matching bra and panties.

A final look at herself in the mirror had her thinking the dress wasn't so bad after all - or did she just feel beautiful after the day of flirting with Joe? - and she was off upstairs to wait. On the way down the basement hallway, she overheard Cornelia's lusty screeches.Some prior ...
