Linda was no virgin. She'd had boys suck her and fuck her, but she'd never had a cock in her ass. She couldn't imagine it, certainly not a cock as big as Scott's.

Oh, you beautiful stud, she thought. She'd know her brother had a big dick. You couldn't look at his crotch without seeing there was something big in there. But she'd never expected such a gorgeous huge prick between his legs.

Horsecock, the girl thought. A cock to make a pussy weep for joy.

And there was her stepmother with her asshole stretched a mile wide by her brother's big prick.

Linda watched it to the end. The only thing she was sorry about was that she couldn't see him squirting in Gayle's ass. But she stayed at the window long enough to see him pull out, and then a moment later she saw the glob of white spunk leak out of Gayle's wide open shit-hole.

Her fingers in her cunt, the girl whacked herself off as she watched her brother's jism leak out of her stepmother's gaping asshole.

CHAPTER FOUR

"You're fucking her," Linda said to Scott.

They were in his room. A few days had passed since she'd spied on Scott and her stepmother together, and now she was confronting him with it.

Scott stared at her. "What the hell are you talking about?"

"You're fucking Gayle."

His face flushed. "So what?"

Linda smiled. "It's always better to tell the truth."

"Listen, Linda-"

"I don't care one way or the other. Maybe it's a little crazy, but so what?"

"You mean that?"

"Yes, I mean it. Anyway, if you can fuck her, you can fuck me too."

The boy stared at his sister. "Oh Christ!"

"I mean that too."

She stood up and unbuttoned her blouse. She stripped everything off except her panties and she stood in front of him with her naked tits jiggling.
