A single glob of jism oozed from his pisshole and slid onto her tongue.

"Ooooh," she purred, letting the slimy nugget run over her tastebuds for a moment. Then her throat pulsed delicately as she swallowed it. That single frothy drop was so delicious that Karen wailed with frustration, longing for more of the succulent stuff.

But there was no more.

Suck and lick as she would, with all her considerable talent, Karen could not coax out another drop of fuckjuice, nor make his shrunken cock swell and stiffen again.

Her head bobbed down and she took his cock and balls together into her lips. Her head tilted from side to side as she mouthed him. Tony leaned back, still panting, holding one hand against the back of her head. He tried his best, humping up into her face and watching her lips pull on his prick, but to no avail.

Yet again, Tony's cock had failed a girl.

Karen raised her head and looked beseechingly up at his contrite face. Her own expression was one of dismay and regret and absolute frustration.

"How long before you can get hard again, Tony?" she asked him in a quavering voice.

Tony hesitated. But there was no sense in lying to her, for she would soon enough find out the terrible truth, and he sighed and shook his head sadly.

"Sorry, Karen," he apologized again.

Now a flash of anger joined the frustration on her pretty face. Her green eyes flared. She looked from his apologetic face to his faltered cock.

"You bastard!" she hissed. "How dare you pick me up and not tell me that you're a premature ejaculator? What a rotten trick to play on a girl!"

"I-I can't help it," he whispered.

Karen sobbed in anguish. Her mouth was watering and her pussy was smoldering and there before her was that glorious hunk of prick – gone limp and useless! She ducked down for one last try, lapping all over his cock and balls, sucking his knob into her mouth, whimpering with need. She slid lower and licked him under the balls, then, ready to try anything at all if it might arouse him, she began to lick up the crack of his ass and push her tongue right up into the tight bud of his asshole.
