"I think I want to be reamed like that tonight," Betty whispered. "After you give my pussy a good pronging, of course!"

"Of course," Rod said just as softly. "But before I do either one I'm going to fuck you with my tongue! I'm going to lap and suck your clit until you cream like crazy and then I'm going to fuck you in both holes until you can't walk!"

"Keep on talking like that and I'll insist that you do all those wonderful things right here and now!"

Rod put his arm around Betty's narrow waist and pulled her close. All he had to do at any time to turn his sister on was just talk about sex. He often talked to her in such a manner when there wasn't a chance for them to fuck or suck just to see her rush to the bathroom or some other private place to masturbate. He'd read that most females didn't reach their full potential as far as sex was concerned until they were around thirty and he figured that his hot-ass young sister had to be the exception to the rule.

They watched the man sag weakly over the woman's back after he'd dumped his load in her dark and tight tunnel, then they moved away from the window. They circled the house, but could find no other places to peek. The heavy drapes were drawn over the living-room windows and all the other windows in the large ranch-style house, including those in their own bedrooms.

It was in the middle of the week so there weren't all that many swappers at the sex party. They only saw four cars, besides the two belonging to their parents, and on some Friday and Saturday nights they'd counted as many as ten cars parked on the street and in the double driveway.

A few times the drapes had been parted just enough for them to see into the large living room. They'd thrilled to the sight of naked couples and even groups sexing it up together – and they'd observed regular orgies in one or more of the bedrooms from time to time.
