Lisa was now completely immersed in the burning intensity of her ass-fucking desire. The lips of her puckered ring convulsed rhythmically around the turgid base of her dad's big cock, sucking more and more of his deliciously stiff meat up her asshole. Panting and squealing, she intensified the rhythm of their fucking, driving her shuddering asscheeks down onto his cock again and again.
Her asshole was completely coated with the Vaseline and her dad's own drippings, and his throbbing prick slid easily into her hole, boring deeper and deeper with every stroke. It was the most satisfying fucking Lisa had ever experienced in her life.
"I'm gonna cum, Lisa!" Frank gasped. He ran his hands caressingly up the creamy curves of Lisa's teenage nakedness, squeezing her heavy tits as his pulsing tool basked in the rubbery warmth of her puckered ring. "I can feel… unh… I can feel my cock throbbing inside your ass! It's too much… I'm gonna pop my rocks now… any second!"
"Feel my cunt, Daddy!" Lisa panted. She arched her back hard, lifting her curly-haired pussy mound so he could stroke it with his fingers. "Unnhh, Daddy, my cunt so hot it's hurting me! Beat me off, Daddy, jerk off my pussy while you fuck me up the ass! Make me cum now! Unghhh, Daddy, I want to cum so much!"
It seemed to take Frank a moment to take in the depraved meaning of his daughter's shameless request. Then his hands moved down her belly to the furry hillock of her pussy, and Lisa shuddered all over as she felt her dad's fingers penetrate the pouting slit of her gurling cunt. Eagerly Frank fingered the pink gash, thrusting his index finger deep into the soaking wetness of her pussy hole. At the same time he managed to shove another inch of his cock into the burning tunnel of her asshole, until Lisa was sure she could feel his huge dick beating all the way up to her heart.
"I'm cumming now, Daddy!" Lisa moaned.
Her cheeks flushed pink with horniness, and her nipples swelled rigid on her wildly bouncing tits. Frantically she began to shove her ass down onto him, fucking her asshole with his swollen sex-meat as hard as she could. "Unnghh, Daddy, fuck me now, fuck my asshole, I'm cumming! Unnngh! Harder, daddy! Fuck my asshole! I can feel it, I'm cumming! Awwwnnnghhhh, God! Fuck me, fuck meeeee, awwwnnn, I'm cuuummmihnnng…"
The frantic spasms of cumming shot explosively through Lisa's loins, making the powerful muscles of her asshole contracted tightly around the blue veined flesh of Frank's hotly pulsing dick. For a second the shaft of his prick grew to absolute hardness inside her asshole, and his nuts began to throb.
Then the gushing load of his cum began to shoot in an uncontrollable stream from the juice-soaked knob of his fat cockhead. Frank gasped loudly and pumped his spurting rod into Lisa's tender asshole as hard as he could, milking the burning stream of his jism out of his bloated balls. It was the hardest cum he'd ever experienced.
"Oh, Daddy," Lisa sighed. She turned her head and showered hungry kisses across her father's leathery cheek, whimpering as she felt her whole body ache with the delicious tingling of cumming. "That was so good! I came so hard, Daddy! I love your big cock so much! Let me suck it now, Daddy! I want to make it all stiff again, so we can fuck some more."
Frank smiled at his daughter and nodded. Giggling, Lisa slid her sweat-slickened asscheeks up his body, feeling the softening length of his cock pull reluctantly from the rubbery lips of her asshole. Then she turned and knelt beside him on the bed, staring down at the swollen tube of his dick.
Frank's cock was hard and damp, covered from head to root with the smeared Vaseline and his own cum. Lisa knew her father's dick had just been up her asshole, but she was much too horny to care. Leaning forward, she took the swollen cock between her lips and wrapped her hand around the base to hold it in position. Then she eagerly began to suck his raw-skinned tool deep into her hot mouth.
"That's good, Lisa, that's good," Frank muttered. Shuddering, he dug his fingers into her long brown hair and pulled her head closer into his loins. "Suck it hard now. It'll get stiff again in a second if you just keep sucking my dick hard! Ohhh! Oh, shit! Suck my dick, Lisa! Harder, harder! Suck my dick as hard as you can."
The shaft of Frank's huge pole grew and grew between Lisa's tightly sucking lips, until his sex-meat was again as hard as a rock. Lisa feverishly began to bob her head up and down over the bulbous crown of his twitching prick, wantonly fucking herself deep down the throat with the reddened shaft of her dad's hotly throbbing cock.
Both of them were much too horny to notice that the door of the bedroom had been opened ever so slightly, and that for the past fifteen minutes father and daughter had been observed by Carl Stanton, Lisa's nineteen year old brother.
