"Shake it!" Elliot grunted.

She speared a finger into her cunthole and wiggled her butt. "Don't stop yet," she moaned. "Give me a little more time."

He ignored her pleas and began moving faster. "Thick you!" he said.

"No!" she cried, turning her head and trying to expel his cock from her asshole. "Don't go so fast!"

"I'm almost there!" he grunted. "Fuck!"

"Oh, no!"

She stopped arguing. It was no use and he would win anyway. She fell forward when he began pounding her shitter. Within a moment he came, dumping his load into her asshole and leaving her limp with frustration.

When he was through, he slumped over on his side of the bed and fell into a sound sleep. She lay there fuming and when she was sure he was asleep, she rose up from the bed and tiptoed down the hall to the bathroom, a robe tied loosely around her waist.

His jism dribbled out of her asshole and wet her thighs as she walked. She passed Jason's room and noticed the boy had forgotten to close his door. Averting her eyes, she continued on her way to the bathroom.

She sat down on the toilet and peed. She rubbed her cunt with the toilet paper and automatically tried to bring herself off, but it was no use. Her mind kept returning to Elliot's selfishness, but now she thought about something else. Her son, lying naked on his bed with the door to his room part-way open.

She had the feeling Jason left his door open deliberately. It had happened too often lately to be an accident. He had a habit of leaving a dim light on in his room too. It was a habit left over from his childhood when Elliot had scared him about goblins coming into his room at night. In any case the teenager always left a dim light on in his room and Kerry had more than once caught a glimpse of the boy masturbating.
