Susan pulled his prick back into her mouth and gobbled down to the large, meaty base. As her nose rested in the thick wiry patch of hair, she began slapping her tongue all around his shaft. The delicious flavor of dried piss and sum assaulted the back of in throat with a salty pungency thirst increased hunger.

"Mmmmmm, and I'll just bet a boy like you has a whole lot of cum!"

"Come on, Sis," Mike said, now desperate for her to suck him. "Eat my cock! God, I can't take this… much longer!"

Susan placed her fingers at the base of his cock, pulling his shaft at a right angle to his crotch. Holding it firmly, she began bobbing her head back and forth, each stroke coming faster than the last until her face was a blur. Within seconds she felt his shaft begin to jerk even harder, and she could taste the steam from his nuts.

"Mmmmmmm," she moaned, probing her finger under his balls, gliding it into the crack of his ass.

"Goddammit! Suck, you cocksucker!" Mike groaned, crushing her face harder into his crotch with his hands, "Lick it good! I'm gonna blow your fucking throat away!"

Susan gave it everything she had, blowing him like he had the last cock on earth. While her hands was playing with his ass, swirling her fingers into the dark greasy hole, down his lean slender thighs, jamming them between his dangling nuts. She knew he was about to go crazy just from the way his rigid shaft was so tight, and her own body was reacting to what she was doing. Her pussy was oozing juices into her panties now, gluing the soft material to her crotch. She rubbed her legs together and felt a pang of ecstasy spear into the back of her cunt.

"Ahhhh!" she gasped, her voice a plea for his orgasm.

"Now!" Mike barked, jerking his hips forward brutally. "Goddamn, now… I'm… fuck! Suck! Unhhhh!"

The first searing blast of cum shot into the back of Susan's throat with smacking force. Then, almost immediately, another thick creamy glob splattered from his cockhead. His climax was so plentiful and quick, she didn't begin to have time to drink all he had to offer. The boiling juices sloshed around his plunging shaft and, finding no more room, dribbled from the corners of her mouth, wetting her chin. A few silvery strands fell onto her tits, causing another ripple of pleasure to spasm her pussy.
