Monday was an exasperating school day for Lisa. Over and over she was asked why she was in such a good mood. It seemed that she had a smile on her face all day—she couldn't help it. After physics class her friend Andrea confronted her. "C'mon, what is it?"
"What is what?"
"You were grinning all through Fielder's class. I know you don't like physics
that
much. Is there something I should know?"
"About what?"
"I don't know…you just have this look on your face—like the cat that ate the canary." Andrea's eyes narrowed. "Did you get laid over the weekend?"
"Andrea! I don't even have a boyfriend!"
"So you say. Is it someone I don't know? A boy from another school, maybe?"
"No," said Lisa firmly. "It's not a boy." Andrea was known around school as something of a slut. She wore her pleated uniform skirt hemmed several inches above the knee, and her standard white blouse fit tight across her generous bust.
"Well, I wish you would tell me what it is so I can get some. I've never seen you look so happy." She thought for a moment. "Did you get a vibrator or something?"
"Shhh! Somebody will hear you!" Lisa glanced around to make sure nobody was listening. "I wouldn't even know where to get one of those things," she said.
During English class Lisa tried to keep a neutral look on her face, but soon she found herself thinking once again about last night with Uncle Tim and her twin sister Linda: trading licks on his big cock like it was an oversized popsicle, eating Linda's freshly shaved cunt while Tim plowed it with his dick, and then finally losing her virginity to that fat prick of his. It had fucking hurt when he popped her cherry! But after that…the pain had given way to an indescribable feeling of fullness as that monster had stretched her tight little pussy. The slender blonde had cum so many times she lost count. Linda had held her hand through the whole thing, reassuring her, kissing her. Afterwards she was so sore she could hardly walk back to her room. As she remembered how Tim had shot his seed deep in her womb, Lisa could feel herself getting juiced up all over again…
She felt somebody nudge her elbow. Sitting next to her, Andrea said, "Come on, spill it," and Lisa realized that she had a big stupid grin on her face again. She could hardly wait for school to let out.
But when she got home Lisa found Uncle Tim-the-dutiful-husband rather than Tim-the-half-drunk-satyr of the previous night. In the first place, Nicole, the girls' aunt, was there to keep Tim in line. Her three-days-on, four-days-off schedule at the hospital meant that she wouldn't be working again until Friday night. Yet it wasn't just the presence of his wife that held Tim at bay—he was feeling truly remorseful about the wild night with his two sexy nieces. Tim knew he had a good thing with Nicole and he didn't want to blow it. He told himself that it wouldn't happen again. As long as the twins didn't tempt him…
After dinner the girls did homework while Nicole and Tim read the newspaper and watched TV. Linda had changed into comfortable shorts and a t-shirt but Lisa still wore her school uniform. Tim loved the way the twins looked in their plaid skirts and white blouses. He glanced over at Lisa and found her staring at him. Her wide hazel eyes had a slightly glazed look and as he watched she ran her tongue around her lips seductively, then smiled. He quickly turned back to the television.
Lisa almost laughed aloud when she saw that her big strong uncle was actually blushing. She wanted his cock again—wanted it badly. Her pussy felt itchy and hot. Sliding her butt forward on the chair, she let her skirt ride up. Holding her book as a shield with one hand the slender blonde teen dropped the other hand between her legs. Her cotton panties felt sticky. Her pussy lips were swollen, engorged. Lisa moved her fingers in a slow circle over her mound and felt wetness leaking into the material.
Tim made an effort to keep his eyes on the TV but it didn't last. Nicole was still deep in the crossword puzzle. He risked a look toward Lisa. Oh shit…her knees were well apart with a book between them, the other hand moving beneath her skirt. And his cute blond niece was still staring at him. He felt his cock stiffen.
As he watched, spellbound, Lisa slowly raised the book so Tim could see as she caressed her sodden knickers. Smiling wickedly, the teenager slipped her fingers under the waistband of her panties and down. Tim's dick was rock hard. He was afraid that Nicole would catch him staring but he couldn't tear his eyes away. This is insane, he thought. Summoning all his will power, he rose from the couch. "Gotta take a leak," he said.
"Thanks," said Nicole without looking up from her crossword. "We really needed to know that."
In the bathroom he splashed cold water on his face while his cock slowly wilted. What was that crazy girl trying to do to him? He looked at himself in the mirror. "You're an asshole," he said to his reflection. After a few deep breaths he flushed the toilet and went back to the living room. Lisa was no longer in her chair, but her book lay face down on the arm. Good, he thought. Maybe she's gone to change into something less…provocative.
But when Lisa came back a few minutes later she still wore her school uniform. She settled into the chair and took up her book. Tim resisted the urge to look for a while but it was no use. His eyes were drawn to his young niece like a ghoul's to a train wreck. When he glanced her way she was looking at him again, book between her legs. But this time when she raised the book she was wearing no panties at all, and her middle finger was buried in her pink folds.
Tim suppressed a groan. "Honey?" said Nicole. "Are you all right?"
"Yeah, sure," he said. "My back's a little sore."
Lisa giggled. When Nicole turned to her, the blond teen sat demurely with her legs together. "What's so funny?" asked Nicole.
"Oh, just this book."
