Knowing what he was waiting for, Kelly released his balls and reached back under them until she found the deep sweaty crevice between his sinewy asscheeks. Probing through the hair around his asshole as he'd taught her to do years ago, her naughty middle finger finally discovered the tight ring of his quivering asshole.

"D'ya like that?" she giggled, aware of how much he always enjoyed what she was doing.

Knowing how much it thrilled him when she screwed her finger deep into his asshole, she probed the tip of her finger around his tightly puckered shitter, feeling his lean muscular asscheeks quivering with anticipation.

"Give it to me!" he roared, unable to stand the suspense any longer.

As she passionately sucked on his big juicy prick, she slipped the tip of her finger through the tight ring of his asshole.

"That's it, baby! That's it!" he shouted with glee.

Ramming her finger all the way up his asshole, Kelly sucked even harder on his fucking cock, aware that he was on the verge of shooting his wad.

"In here!" she suddenly squealed, releasing his prick from her mouth as she rolled onto her back and spread her shapely legs for him. "Shoot your hot jism in here!"

"Are you ready?" he excitedly panted as he crawled up between her delicious splayed thighs.

"You better bet your sweet ass I am," Kelly giggled. "I'm ready for everything you've got, Daddy."

Little Susan couldn't believe what was happening. It was bad enough that Kelly had been sucking and licking her dad's big cock, but the idea of him fucking his own daughter was outrageous. Susan could hear her heart pounding loudly in her breast as she watched her father's huge prick slowly advancing toward Kelly's cunt.
