"Don't cum"

Tessa looked at him with confusion. Then she quickly smiled again and kept thrusting, as if she'd heard him wrong.

But she hadn't. Jim pulled his fingers off his step-mom's clit and repeated himself. "Don't cum."

Her lips trembled. "But Mommy needs to cum."

Jim quickly slid his body out from under Tessa's making her hit the floor with a thump. The oozing sexiness of the moment faded into wild desperation.

"Doesn't Mommy want to make Jimmy happy?" Jim asked.

"Of course."

"This is the only thing that will make Jimmy happy. Don't cum." It wasn't entirely true. Getting to bury his cock deep inside his step-mom would also make him happy. But since that wasn't an option and yet Tessa kept insisting she was too far lost to make decisions, Jim decided to embrace his unconscious frustration. If he had to control himself, so did she.

He stood over her as she laid on her back. "Take those panties off and spread your legs." Jim demanded. Tessa did just that, sliding the wet rags that once resembled underwear down her legs and spreading herself for her step-son.

It was a lovely sight, finally being able to see her cunt in all it's glory. Jim grabbed his cock and jerked it in her direction. Tessa opened her mouth and stuck out her tongue and Jim decided, sure, why not, and spilled his jizz all over her pretty face. The cum that landed on her tongue she swallowed. The rest, he told her to leave.

She stayed laying on her back, legs spread, as recomposed himself and slipped his pajamas back on.

Her body twitched. "J..Jimmy? When can Mommy cum?"

Jim enjoyed the new power. "Not for a while." He said.

"P...please.. Mommy needs to cum for Jimmy... Jimmy is her beautiful boy and if Mommy doesn't cum soon she might go mad."

Jim knelt down next to his step mom and ran his fingers through her sweaty blonde hair. "Won't that be fun?"
