Karen was genuinely curious, and in no way judgmental. Her brother had been letting her tag along to their Saturday afternoon "exploring the woods" for five weeks now. The boys were completely at ease with Brian's little sister and let her watch to her heart's content, even "help out" some. Helping out consisted of her getting down next to a pair of rutting boys and giving a running commentary, encouraging them, praising their tight butts and rigid cocks. Once in awhile she was permitted to hold a dick and steer it into another boy's butt or mouth. And she frigged herself shamelessly throughout.

The oldest boy Carl, who was fourteen, snorted derisively. "Fuck no man! No way I'm gonna plug a stinky ol' cunt!" The other boys laughed with him.

Then David spoke up. "I kinda wonder about it sometimes though. I mean, a girl's got an asshole too, just like us. And I seen pictures of 'em sucking cocks."

"Yeah, the guys cum too!" Brian observed. "We saw a film once, didn't we Karen?"

Karen smiled. "Yeah, one of Daddy's videos. It was neat."

"No way!" Chris objected. "Guys can't cum with girls."

Even Carl knew that wasn't true, but Chris was young and convinced. He'd heard that somewhere, and it was part of his "truth".

Karen busied herself with her role as hostess, serving the drinks and keeping a supply of chips and salsa on the table. They were in an abandoned cabin deep in the woods. Over time the boys had dragged battered furniture and bedding out to the cabin, so they could enjoy their orgies in a bit of comfort.

"I don't know," Carl went on. "A guy fucking a girl sounds sick to me. Guys should hang with other guys!" There was little quarrel with his sentiment: the boys were at an age where they thought girls were yucky and preferred the company of their peers. Of course, Karen, being Brian's sister, and a participant in their fun, was accepted as a "quasi-guy."

Karen had noticed the last couple weeks that David often stared at her chest. In fact, it was David who'd suggested that Karen be topless (it was her own idea to switch into the shortest, tightest cutoffs she had, so tight they ground into her nine year old pussy, then finally just to shuck them off). When David looked at her that way Karen got real antsy, an itchy feeling in her little quim. And she saw that David's cock would get stiffer than usual when he looked at her.

"Hey, you ever fuck your sister?" twelve year old Stan asked Brian. Stan was getting a blowjob from Chris.

"Shit no!" Brian objected. "She's my sister. And I never fuck girls."

"I dare you to let her give you a blowjob," Stan went on.

Instead of flat out rejecting the idea, Brian said, "Fuck man, Chris just sucked my cock off for Christ's sake!"

Chris, who was just ten, was an avid "anything goes" type, freely offering his asshole to anybody who wanted it, and sucking dick more passionately than any of the other guys. His weenie was tiny but always stiff.

"I bet I could do it good," Karen declared, licking her lips in contemplation of the prospect. Brian's cock was yummy and she loved how it felt when she helped him jerk it. It was as big as Carl's too.

Thirteen year old Martin, the last boy in the group, stood up with his thick prick in his hand and said, "Karen, you can suck on mine if you want to try it. But you have to swallow when I jiz, okay?".....(cont)
