But by then Jimmy had already finished coating his cock from base to crown with petroleum jelly. Lori gasped as he started smearing it over her asshole, darting his finger into her shit sphincter to coat the interior as well. Lori spread her ass cheeks even wider, and looked at him over her shoulder.

"Okay, Jimmy, that's enough! I'm ready for you now! Hurry, Jimmy, fuck Auntie's asshole! Stuff it full with your big, hard cock!"

Jimmy mounted his fuck-hungry aunt, aiming his swollen cock head at the Vaseline-slickened entrance to her bowels. Lori shuddered as she felt his huge cock spearing into her asshole, spreading the tightly-muscled ring to the bursting point round the invading thickness of his meat.

"Unngghhh! Oh, Jimmy, that feels so goood!" Lori started humping like a bitch in heat, wriggling at the same time to help her nephew's cock slide all the way into her shit tunnel. "Fuck my asshole good, Jimmy! Oh, fuck, oh, shit, fuck my little asshole with your big, hard cock!"

Jimmy stabbed relentlessly into her sucking ass tunnel, moaning as he felt the constant pressure of her shining muscles gripping around his prick. He paused with first a third, then a half, then two-thirds of his cock rammed up her shitter, giving his naked aunt a chance to get used to the size of his stiff prick.

"All the way in now, Jimmy! Fuck my asshole good, baby! Ram that monster all the way up my asshole!"

Jimmy took a deep breath and then slammed his cock to the hilt in her burning asshole, packing her ass to bursting with the cum-throbbing stiffness of his cock. For several seconds belay motionless on top of her, moaning as her tender little shitter sucked and spasmed around his prick. Then he pulled out slowly, and then he thrust his cock back in again, beginning a slow, hard, fucking rhythm in and out of her shitter.

"Harder, Jimmy!"
