Stacy had daydreamed many times about being fucked, and about others fucking, and she thought a little wildly that at least one of her fantasies was coming true. It was just as exciting as she'd thought it'd be. It was beautiful, really, the rhythmical way each couple moved together. She had all kinds of still pictures, but they paled greatly when compared to actually witnessing sexual intercourse-fucking.

Again the men switched back and forth from woman to woman, fucking for only a minute or two each time before they shifted, and Stacy didn't really pay enough attention to that part of the erotic scene to know how many times a shift was made. It was enough just to see the glistening cocks from time to time, imagining how it'd feel to have one shoved into her steaming snatch each time there was a change of partners – and then wondering how it'd feel to have a prick pistoning in her palpitating pussy.

Because a few times she seemed to be right on the brink of a blissful orgasm. But she'd close her eyes and grip the window sill until her knuckles ached and somehow keep from spasming. She was afraid that she'd moan or cry out and she didn't want Betty to know that she was so passionate. That pretty girl seemed surprisingly calm and cool and Stacy knew that it'd be very embarrassing to lose control of herself.

Besides, she thought a few times, it wasn't the first time she'd been as hot as a firecracker and couldn't or didn't do anything about it. Sometimes she could get almost as sexy-hot while sitting in a classroom and having erotic daydreams and the wildest fantasies possible.

"They're long-lasting studs," Betty said after about ten minutes had passed. "That's nothing unusual, though. The swapping husbands are a sophisticated bunch, of course, and I guess it takes something really extra to make them shoot off fast like a teen-ager. Come to think of it, I know quite a few boys able to last and last! They're going to try something else now."
