Rick opened the door and entered.

His sister's feet were toward him, and when she had flung herself down, the skirt of her dress flew to the lovely cheeks of her ass. Her slender, shapely thighs were fully revealed, as well as the tight panties that covered the sweet swells of her asscheeks. For a moment, Rick stood and gazed at the beautiful view, then moved to the bed and sat down on the edge of it.

He looked at his sister's lovely thighs and the tight way her panties fit. He could see the attractive crease of her asscheeks where they met her thighs, and felt a tingle in his balls.

"What did you mean about Susan?" he asked, his voice low and slightly shaky.

"You know," she sobbed, not looking at him.

"No, I don't, Judy."

"I saw you!" she sobbed. "I saw you at school."

"What did you see?"

"You and… and Robert," she said, her voice muffled by the pillow. "And Susan is Robert's sis… sister!"

For a moment Rick didn't say anything. Then, tentatively, he reached out and touched her lower leg.

Susan felt his hand on her calf and she began to tremble. She waited for him to say something, but he didn't.

"You don't… you don't…" she began, stumbling over the words she wanted to say. "Oh, Rick! Why? Why did you do that to her?"

"Well, gosh…" he said. "Judy, you know how it is. I mean, a guy… a guy just has to… well, boys do that."

"Sure they do," she agreed, "but girls? Do they do it, too? I mean, is Susan the only one?"

"She's the only one I've… you know."

Judy turned over swiftly, glaring up at her brother. "You don't need her!" she said, her words hissing. "You don't need to touch her that way."

When Judy turned over, her dress remained past her hips. Rick found himself looking at the tightness of his sister's panties. Again he saw the bulge of her tantalizing cunt, the dark shadow of her sparse hair. Judy's legs were open slightly, and he was sure he could see the slit of her pussy.
