In the office.

"We haven't had lunch at your office in a while." Bryce said, thinking to himself that Florence would be there, she worked in sales after all and he might be able to see how they interacted, or even figure out a way to see them...together, or get together with the short, plump ebony sexpot.

This thought, along with...everything, had his cock hard as a rock, pressing against her ass, which was the only hole of hers he hadn't sampled yet. No, he hadn't tried her mouth yet, either. Ultimamom's and Ultimagirl's, but not Ultramom's. Hmm...Maybe at lunch, but for now...

"What a nice idea. Will you bring me something to eat?" Brenda teased, splitting her ass cheeks on his cock as he fingered and groped her. Her writhing suggested he was doing well, but she kept her tone mostly level.

"Oh, yes, but for now, I want a piece of this ass and some breakfast." He guided Brenda so she was lying across his lap like a naughty schoolgirl, his t-shirt up around her waist, his cock pressing against her belly and his hand running over the deliciously firm ass he was about to fuck.

"Oooo, I get to be the first one buggered?" Brenda cooed.

"Yes. And the last one to give me a blowjob." Bryce noted.

Shelby delivered more food. "I was the first to get fucked." She said, believing it to be true, though in fact, she was the last to be fucked.

"Could you help me get her ready?" Bryce asked.

"How?" Shelby asked, confused.

"I don't want to hurt her, or break my cock off in her ass, so we need some lube."

There were, in fact, a number of lubes available. It was a kitchen, there were oils and, of course, there was Brenda's own naturally occurring lube, which was no longer dripping onto Bryce's pants, but instead down her own silky thigh, there was Shelby's own lube, which had made the front of her pajamas visibly wet and whose scent mixed with Brenda's to make the room smell of sex. She didn't use any of those. Whether it was the night she'd spent under Brenda, or the command that gave her a repressed desire to submit to the mothers, or something else altogether, Shelby chose a different path and instead knelt behind Brenda, spreading her ass cheeks and with her own cheeks as bright red as the tongue she shoved into Brenda's ass.

Bryce damn near came on his mother's ass at that sight. Shelby's blue eyes were locked on his, making it clear that this submission, this humiliation, was all about him. One hand left Ultramom's ass and stroked Shelby's blonde hair.

"Oh! My! God!" Brenda said, acting as if the tongue was a cock. "Is that your tongue? She is such a whore! Such a dirty little slut!"

This time the pain in Shelby's eyes was not matched by arousal.

"Indeed she is." Bryce noted, drawing a chuckling moan from Brenda. The pain flared higher in Shelby's eyes. "Which is why I think I'll fuck her, not you." He concluded.

The pain vanished. The chuckle stopped. The rimming stopped too. "WHAT?" Brenda began.

"You heard me." He said.

"But--but--but--" Brenda stuttered.

"Yes, hers, not yours."

Shelby laughed.

Brenda spun to face his fiancé, **** was an inch away. A second later Bryce was between them, his ass right in front of Shelby's face. Mother and son stared at each other for a long second.

**** dissipated.

"But I'm a dirty little slut too. I'm a whore too. I've been your little lezzie slut, just like her." Brenda finally said, lowering her head and looking up at him through long lashes.

"And none of that's bad?" He asked.

"No." Brenda agreed.

"So you'd have no problem kissing Shelby fresh from your own ass?" He asked.

"No." Brenda agreed.

He stood aside and Brenda dove forward, driving Shelby to the ground and kissing her, dominating her, tits mashing against each other. Though Shelby was blushing, now it was humiliation and arousal, not pain. Brenda knelt over the woman she'd insulted, knees resting by her thighs, meaning that their leaking arousal was meeting at the crotch of Shelby's panties and at their still locked lips, though in different fluids.

He had four holes to choose from.
