Skip to it happening

Jim felt the pressure build in his bladder. He held it for a moment but not too long and then let it loose. The warm stream of urine sprayed through the air and hit his step mother in the face. She groaned and turned away. So it ran down her naked body, her neck, her tits, down through her thighs and into the shower drain. Mom watched.

It had been surprisingly easy to make it happen. Mom had simply blackmailed Tessa. "Would you like your husband to know that you set it up that his son caught you fingering yourself?"

"He won't believe that." Tessa said.

"Will he believe it when he also finds out your slut nature can't be controlled and includes fucking seven of his employees and I believe one competitor."

Tessa fell into line.

Tessa was a slut. There was no debating that. But she was not a piss slut. She didn't enjoy what was happening at all.

Jim finished, aiming at her tits.

"Okay," Mom said, "Now we're going to do it again until you do it to Jim's liking."

Tessa gave her a desperate look, "Please... don't make me take it in my mouth. Let me keep my dignity."

Mom laughed. "Please. The quicker you realize that your dignity isn't even an option, the quicker this will go for you... So I guess, keep resisting." She turned to her son and winked. Mom was enjoying every second of this.

Jim quickly downed another glass of cold water. What was happening was nine kinds of insane, kinky, and naughty. But there was also something utilitarian about it. He had to drink more water before he could go again. There was a lot of waiting. It wasn't exactly as sexy as it had been in his imagination. But it was still wild.

Tessa took a moment, closed her eyes, breathed deeply. "Okay, I'm ready."

"For real this time?" Mom asked. Tessa nodded and Mom turned to Jim.

"I'm not ready." He said. Unsexy.

"Mind if I take a turn?" Mom offered.

Jim didn't mind, but something about the suggestion was unavoidable. He nodded his approval even though he knew there was no getting away from it.

Mom, who was wearing a bra and panties, slowly slipped her panties down off her shapely legs. And there it was. Jim was looking right as his own mother's pussy. She squatted above Tessa, smiling proudly. "Wide open now."

Tessa parted her lips. Tessa let her mouth fill then swallowed. Then coughed. Then opened her mouth for more.

Jim told himself he was turned on by the sight of his step-mothers total subjugation at the hands of his mother, and at his own desire. He was not turned on by the sight of his mom's lovely looking, mature, cunt. He lied to himself.

"Are you satisfied?" Tessa said after it was done.

Jim wasn't satisfied. This was it, the filthiest thing he'd ever do in his life. There was no doubt about that. He had to make sure it was as filthy as possible. How could he be satisfied already?
