Adonna was so furious. This was unimaginable. How could Zipser do this to her?
Smirking above Adonna was Selbi, her twin sister. Adonna and Selbi had always been terribly competitive, over grades, boys, and careers.
Adonna was a famous biochemist now, and Selbi had taken over their father's chain of luxury resorts.
This had caused Adonna to intimate to Selbi that she wasn't bright enough for a science career, and this had always enraged Selbi.
And now, in mid session, being spanked and disciplined by Zipser, Adonna's male Master, he'd brought in her sister.
Adonna was kneeling naked on the floor, and Selbi was standing over her, fully dressed and laughing her ass off.
Adonna bit her lip and wanted to get up and punch Selbi, but she dared not take her hands from behind her back until Zipser permitted this.
And Adonna found her clitoris was moistening, and oh, she wanted to masturbate!
The humiliation of being exposed like this to her sneering, tight-assed bitch of a sister was incredible.
Selbi smirked at Zipser. "What the fuck is going on here? Look at those mouse-traps on her tits. I never knew Adonna was such a weirdo."
"I'm not a weir-" Adonna tried to respond, but Zipser leaned down and slapped Adonna's face hard.
"Did I tell you that you could talk, you little pustule?"
"No, Master." Adonna looked at her knees. They were hurting badly, she'd been on the wooden floor for nearly an hour.
Zipser didn't permit Adonna to just kneel with her ass sitting on her feet, no sir, she had to be up on her knees with her chest jutted out, no matter how exhausting it was.
But she loved Zipser! And she'd told him that she wanted to be humiliated and punished as cruelly as he could give it to her.
Selbi smirked. "And you PAY this guy to do this to you? Dad asked me what you were spending the trust money on, since you get a fairly good salary. He'll never believe this shit."
Adonna blanched. She was thirty-six years old, and it was outrageous that she was still the beneficiary of a trust fund. Selbi got her inheritance from the grandparents directly, as she was far better in money matters.
And the folks were talking about making Selbi the trustee after they were gone!
It was true that Adonna had had a little nose candy problem in college-well even for a few years after graduate school. She'd gone through five detoxes and three rehabs before that had cleared up.
Back then, she'd so envied Selbi, as Selbi could party on the weekends, and stop when she wanted to.
But Adonna had always been an addict. She couldn't just skip one class, she would start cutting full days, and of course she ate like a pig.
Perhaps if she hadn't gained so much weight, Adonna could have gotten Zipser or some other cute Master to dominate her for free, right?
Now Adonna was weeping in abject humiliation.
"Oh, don't tell your dad about this." Zipser objected, realizing this might dry up serious income for him.
"Maybe I can have Adonna make it up to you some other way. Ever had your pussy licked?"
Selbi grinned. "Sorry, big boy. I like the pole more than the hole." She trailed a red-tipped finger down Zipser's broad chest. "We could you know, arrange something personally."
This could be a problem as Zipser was gay as a goose, but he could work with it.
Perhaps a distraction.
"Would you like to discipline your bad sister? She's your younger sister, right, by about ten minutes?"
"Eight minutes." Adonna spoke up, before forgetting her code of silence. But the age thing had been a point of contention between the twins since they were young.
