The pert teenager pushed her tits out and smiled as she thought about her brother. She'd noticed him staring at her tits lately. Her tits had been like two walnuts until six months ago. And then suddenly, almost overnight, they'd sprouted and grown until now they were like two good-sized cantaloupes.

When her mother wasn't around, she hardly ever wore a bra. Like today. When she and Tommy decided to play tennis, the teenager decided not to wear one. She wanted her titties to bounce around. She wanted her big brother to notice them. And he had.

She knew that was why she'd beaten him. He'd never stopped staring at her jugs. She opened her eyes now and glanced down at her boobs. God, it was nice to finally have tits! The twin peaks pushed against the bondage of her tee-shirt and wobbled as she moved.

She noticed several of the poolboys leering at her, but she ignored them. A few of them were cute and she dated them occasionally. But right at the moment the only boy who really mattered was her brother.

"How come you're not in the water, shrimp," Tommy puffed, dropping down on the glider next to her, and Darcy opened her eyes with a grin.

"Don't call me shrimp," she said, eyeing his crotch. For an instant she caught a glimpse of his dick when he moved his leg a certain way.

"It's your name, isn't it?" he teased, his hand shielding his eyes from the sun.

"Haven't you noticed I've grown?" she smiled, pushing out her tits.

"Yeah, I've noticed," he said, turning his head away.

"Well, don't you like them?" she said, deliberately jiggling her boobs.

"Shit, you're my sister!"

"So what? All the other boys like them."

He didn't answer and the little redhead moved her legs apart to give him a look at her crotch. Her own eyes were glued to his fly and she smiled when she saw the bulge inside pulsate.

"I think you like them but don't want to admit it," she giggled, crossing one leg over the other. "That's what I think."
