The boy had always considered his twelve-year-old sister as a pest, but her almost-bare ass strangely excited him. He suddenly wondered if a girl's pussy was hot and juicy like Red's big sister's had been. The longer he stared at her smooth bottom, in his the more his cock throbbed pants. Unable to stand it any longer, he walked over and sat down by her on the floor.

"Is that a good show?" he asked, nervously placing his hand on the back of her thigh.

"I guess so," she'd absently answered, her undivided attention on the television screen.

Sitting next to her on the floor, he cautiously moved his hand up between her thighs until his finger slipped under the crotch of her panties.

"Ooooooooh, Tom," she giggled. "That tickles."

"Does it feel good?" he panted, probing at her slit with the tip of his finger.

When Heather made no attempt to stop him, he continued moving his finger around until he felt the hot wetness of her slit. His cock began throbbing wildly as he slipped the tip of it in between her hot juicy cuntlips.

"NOW that feels good," she giggled, wiggling her hot cunt around his finger.

"May I see your snatch?" he whispered, working his first knuckle in and out of her slippery hole.

"Sum," she beamed. "If you'll keep playing with my pussy."

"Do YOU like this?" he panted.

"Heck, yes," the girl giggled. "I play with myself all the time, but this is better."

"Do you?" he asked in a surprised voice.

"Sum," she beamed. "And last month I learned how to finger myself off."

"Now can I see your pussy?"

"Sure," Heather whispered. "If I can see your prick."

"What do you know about pricks?" he asked, shocked at his twelve-year-old sister.

"That's what boys fuck girls with," she wailed.

"Who told you about fucking?"

"My friend, Elain," was her answer.
