For the first time ever, Dave opened his sister's blouse. When the garment was, on the floor, Judy's back still to the door and not knowing her mother was watching, he removed her tiny bra.

"You sure have some pretty titties, Judy," Dave said, cupping his sister's hard little tits. "Why don't we do something different now?"

"What do you wanna do, Davy?" Judy asked.

"Get naked," Dave said, shooting a look at his mother. "Take everything off. I want to see your little pussy."

"Oooo, I'd like that, Davy!" Judy gurgled, peeled her tight shorts off. Her small panties followed, and Joann found herself looking at her daughter's naked body, at that succulent and very tight ass.

Dave, his attention still on his mother, his eyes bold, removed his pants. His cock strained out, jerking in hardness. His balls hung low and heavy, and Joann couldn't take her eyes from them. Dave pulled his sister against his body, sliding his hands down her back to the cheeks of her sweet little ass. He cupped her ass cheeks, squeezing gently, watching his mother.

Very slowly, Dave turned his sister around. When Judy saw her mother standing there, she gasped and tried to crouch, an arm over her perky tits and a hand trying to cover her cunt.

But Dave pulled her arms away, forcing his sister to stand upright. His cock pressed at the cheeks of her ass as they stood and looked at their mother.

Slowly Judy began to realize they weren't in trouble. She read the expression in her mother's eyes, and grinned nervously. Joann didn't respond to the grin. She was frozen against the door by the sudden excitement that bubbled through her body, by the power of her pulsating cunt. She gazed at her daughter's naked tits, seeing how hard and small they were, seeing the candy-pink nipples bursting with hardness. She saw the small waist, the flat stomach, the swelling thighs, and then she saw the sugary slit of Judy's cunt. A tuft of silky hair was at the top, but, otherwise, Judy's cunt was hairless.
