"That's your problem. I have my reasons," Franny said with a laugh as if she couldn't have cared less about what her sister was saying.

"You little cock-teasing bitch!" Lily cried as she hauled off and slapped her hand across Franny's face so hard that her red handprint was left on the younger girl's snow-white flesh.

"Lily, you hit me!" Franny whined, feeling her little pussy beginning to throb.

"What're you gonna do about it, bitch?" Lily demanded.

"Why don't you take all your clothes off and I'll show you what I can do about it."

"My God! What are you saying?" Lily cried, suddenly turned-on.

"You know what I'm saying. Let me make you feel good, Lily. You want me to make it with everyone in the family. Well, maybe if you and I get it on… well, you know, maybe that'll be a kind of start for me."

Franny ran her hands over her own tits.

"Say no more!" Lily gasped, unable to restrain her lust for her sexy little sister. She quickly peeled her own clothes off and turned back toward the younger girl who was watching her with eager eyes.

"Get on top of me now," Franny begged, already beginning to twist and turn on the bed.

With a little moan, Lily sprawled on top of her sexy sister. Their lips met hungrily. Their tongues touched, exploring each other's mouth boldly. They were both breathless with passion by now, and they rubbed their stiff nips together.

Lily moved down slightly and kissed her young sister's tits. She sucked her nipples hard and then flicked the tip of her tongue back and forth across the little hard-ons.

"Oh, God yes!" Franny whimpered helplessly.

She spread her legs open as wide as she could get them. She felt her pussy swelling and getting wetter. Her clit was erect and throbbing.
