Tom recalled that Elain was the rather homely girl with big tits that the boys followed around.

"Does Elain really let the guys screw her?" he asked.

"Sure," she giggled. "She fucks every day."

"Good for her," grinned Tom, making a mental note to be more friendly with Elain. "Now can I see your pussy?"

"If you promise to let me see your cock," she smiled, rising to her feet and pulling her dress off.

"I promise," he panted.

Tam's eyes opened like saucers when his sister was standing completely naked in front of him. Two breasts were just barely starting to develop an her otherwise flat chest, but her nipples were big and firm. His eyes drifted down over her gently rounded tummy to the pink slit between her legs. Tom had never seen a twat before, but it seemed quite big and puffy for such a girl. He could see downy wisps of soft brown hair lightly surrounding her juicy young slit.

"See," giggled Heather. "My pussy's startin' to sprout hair. Pretty soon I'll be old enough to fuck."

"I can see," he grinned, staring hungrily at her naked cunt, thinking how much he'd like to stick his cock in it.

"Do you want to finger it?" she asked.

"Shit, yes," he answered excitedly as the girl spread herself out on the couch.

Sitting down next to her on the sofa, Tom nervously ran his hand up between her soft bare thighs until he touched the wanton slickness of her dripping cunt.

"Oh, Tom," she whispered. "That feels wonderful."

Closing her eyes, Heather smiled contentedly as she felt her big brother's finger going deeper and deeper into her horny cunt. Her naked body writhed deliciously when he began plunging his thick middle finger in and out of the hot wetness of her young pussy. Tom had never dreamed that a girl's cunt could feel so juicy and slippery.

"That's it, Tommy!" she squealed with joy she speeded the tempo of his thrusts. "Bring me off, honey! Bring me off!"
