"Jimmy…" she whispered in passion.

Her fingers opened, her right hand lifting upward. She cupped his balls in her hand while he stood jacking off and feeling her tit. The heat of her son's young balls seemed to blister her palm as she closed her fingers about them.

"Ohhh, Mom!" Jimmy grunted as she squeezed his balls, his tight fist jerking rapidly back and forth on his cock.

Sarah gripped Jimmy's balls and watched his cock, her eyes smoldering as her lips parted. She wondered if he was going to come off in her face, and what she would do about it if he did. She had never seen a cock squirt before, had never had her face so close to one. It was exciting, making her shiver and her mouth become strangely wet until she had to swallow. There was an unusual tingling sensation in her throat, not unlike the way her cunt tingled in heat. She was feeling and seeing things that excited her, things she had never even thought about a week ago… until she had given in to the impulse to lift her dress at the bank's instant teller.

Another impulse was coming to her, a strong urge to close her lips around her son's cock, to taste it, lick it, suck on it. It was a crazy desire, because Sarah had always felt revulsion for that when anyone ever mentioned such things. Women that allowed a man to put his cock in their mouths were sluts, whores, she told herself before. A man pissed out of that thing, how could any decent woman take it into her mouth? Yet that was what Sarah wanted to do now… feel her son's hot, hard cock inside her mouth.
