Her pink tongue, with nerve-tingling licks on the outstroke, was making the head throb and jerk as though his heart itself were beating inside it. He bent his head forward and watched through widely bulging eyes one of his hands tangling tighter into her bobbing head and the other fondling her sensuously swaying tits. He made a hard fuck forward and almost all of his long blood-thickened cock disappeared until only a little stretch of it showed white and glistening protruding from between her rapidly working lips. Her cheeks hollowed on the outstroke and expanded obscenely on the instroke. He withdrew and the thin elastic rim of her lips pulled out grotesquely, clinging to the flesh of his warmly tingling cock as though held there by invisibly fingers. Her tits jerked and danced below her lewdly pumping torso, one of them lifting and falling in his hand and adding to the lust-inciting picture. "Lick it right under the ridge," he said hoarsely whsle he watched her. "Ooooohhhh, that feels so damn good!"

"Do you like it when I play with your balls at the same time?" she breathed hotly around his stony cock.

"Oh, God, yes! Milk your fingers over the skin. Do that, too!"

Deeply he sighed, and his head sank back in the mattress as she massaged the soft resilient skin of his testicles gently with one hand and stroked the base of his cock between the thumb and forefinger of her other hand as she continued to suck rhythmically up and down. She increased the speed and he could feel the silky softness of her tongue twirling faster and faster around the saliva-slicked, hardness at the apex of the withdrawal, the stroke of her fucking tongue ending in a magic flick across the tiny opening of the glans at the end. He flexed his ass, thrusting his hips back and forth and then arched his back up off the mattress to grind his wildly bobbing loins hard up against her face.

Natalie could feel his throbbing reaction beginning inside his balls and began to suck his lust-swollen cock a little harder, increasing the pressure of her mouth, the tips of her teeth digging gently into the hard resisting flesh, leaving thin white trails where they had scraped the blood beneath the surface of the skin.
