Then a mischievous thought occurred to her – she knew just the trick to really make young Joey spurt. Evelyn slid her left hand between his legs, rubbing it between his ass cheeks. Joey made a yelping sound as he suddenly felt a strong forefinger pressing onto the puckered ring of his shitter.

"No!" he gasped. "That's dirty!"

But Evelyn wasn't to be denied. She stuck her finger deep inside his asshole, groping for his prostate as she continued sucking and jacking wildly on his cock. Then she found it and rubbed it skillfully with her fingertip. Joey shuddered as his meaty cock swelled to total, tingling stiffness down her throat.

"I'm cuming! Oh, fuck, Aunt Evelyn…"

The white seed blasted down her gullet, in such an incredible tide of shooting cock juice that Evelyn thought his balls must have an endless supply of jism. No one, she reminded herself happily, could shoot off like a horny young stud.

His prick pulsed violently between her lips as it disgorged its sappy load, the knob bouncing up from her tongue to slap obscenely on the roof of her mouth. Still Evelyn continued to suck and jack his cumming prick, pumping her finger in and out of his tight, mushy asshole just the way she liked a lover to finger-fuck her cunt.

He was cuming so hard that it was nearly painful to him. Joey winced and stamped his foot on the shower's tiled floor, shuddering as spurt after spurt of hot spunk spewed from his balls. Evelyn swallowed the cock milk as fast as she could, but even she couldn't take it all. The frothing ivory goo burbled out round her sucking lips, caught by the shower spray as it dripped down her chin.

"That… that's enough!" Joey yelped. "I can't take anymore!"

Swallowing the last of his cum, Evelyn withdrew one hand from his smoking cock and the other from his ass. She smiled up at him as she swallowed hard, gulping down the last of his jism. Then she reached around him, shutting off the water as she rose to her feet. She gave his still-rigid prick one last squeeze before pushing open the stall door.
