She'd been spying on him

"So, you're after Little Red's pussy."

"Her name is Wendy. She's nice."

"She has a nice ass you mean. But those freckles. Don't they gross you out?" To his surprise, Karen ran her hand up and down his upper arm. Probably because he was still board-stiff from his kiss and feel-up with Wendy, the sensation was erotic... although being erotic with his sister was weird.

"I meant that she's nice."

"I saw you pawing at her chest. She doesn't have much there, does she."

"I'd say she's about the same size as you. Probably a B cup."

"And you know my bra size how? Have you been perving in my underwear again?"

"Hey, I live in the laundry room, remember."

She laughed. "That and you're a pervert."

She practically dragged him to a corner where the pool fence and the big house five car garage blocked the view from almost every direction. "So you really think she has better tits than I do."

"I never said--" Matt stopped talking because his sister was unbuttoning her top.

If he hadn't been frazzled, he would have noticed long before that she wasn't wearing a bra. {if Karen>40}Now, she stuck her naked breasts in his direction.{endif}

"You have fantastic breasts, Karen."

"I never thought my brother would get a date here before I did. How weird is that?"

"I'm sure guys will ask you out. Give them time to--"

She laughed. "Trust me, I don't have to wait, they've been asking me out all week. They've asked me to go into the men's bathroom and suck them off. They've asked if I'll do them and their three best friends. They've asked if I'd mind being their cum-dump while their girlfriend is on summer vacation with her family. You can't believe some of the wonderful 'dates' I've already been invited on, Matt. What's wrong with me. Do I look like some slut who's only good for fucking?"

He drew her into a hug. "They're rich assholes. They know we're from L.A. and they think everyone from the city is scum. But you're not. You're beautiful and smart and funny."

All of which was true. She was also hot and her {if Karen>40}naked{endif} tits were pressing against his chest.

Shit. What should he do?
