"I don't always wait until night," Shari snapped at him, "like some people I know."

"That's enough bickering," Joyce said. "Bobby, sit down and listen to what I've got to say."

Bobby caught a peek of his sister's thighs, and his cock suddenly swelled into hardness. He crossed his legs and waited, wondering why the sight of his sister's legs made his cock get so hard. He had never felt that way before about her.

Joyce told him what had happened to Shari, and his eyes went wide. He wasn't shocked or embarrassed by what his mother said. On the contrary, he felt jealous that Shari had been fucked and he was still just jacking off.

"Did you like it, Shari?" he asked before his mother realized what he was saying.

"None of your business!" Shari snapped.

"Okay, kids, stop it," Joyce said. Then she looked at her daughter. "Did you, Shari?"

"Did I what, Mom?"

"Like it?"

Shari didn't answer, but Joyce saw the sudden glow of heat in her dark eyes, and she did not miss the shiver or the soft smile on Shari's pretty face. "Yes, you liked it," Joyce said. "Now, the question is… what are we going to do about it?"

"I can beat up David and Mike," Bobby said, his voice squeaking. "I'll beat their asses good!"

"No. You won't," Joyce told him. "You're smaller than they are. Besides, what I have in mind would be much better."

"Tell us how we're gonna get back at them, Mom," Bobby said. "If I can't beat them up, how are we gonna get back at them?"

Joyce took a deep breath. Watching her children closely, she outlined her plan. As she talked, she saw their enthusiasm. Shari squirmed on the couch and Bobby's eyes glowed like hot goals. A peek at his lap showed Joyce that his cock was very hard.

"Hey, that's a good idea, Mom!" Bobby yelled. "I like it."
