One more punishing position.

Jenni has to endure one last bit of 'fun' from her Step-Sister...

This time, she's in a form of a hogtie, only with her legs spread wide and up.

A dildo powered by a machine- a new toy that Donna wanted to test run for you- is inserted into Jenni's pussy.
As it starts to fuck her, the blonde submissive discovers another thing it can do...

A blast of cold water comes on her pussy!

"You like that? It's a little bonus for sluts like you.
Good ones get warm water. Bad ones like you get the ice cold stuff," Donna says.
"Tell us that you love it," you add.
"I...love it, Master and Mistress."
"Very good. She knows who to address first still," you say with a smile.

The combined stimuli of the dildo and the water makes Jenni cum hard.
She has no time to catch her breath though, as it just keeps going...

After four orgasms, Jenni is spent.

The water is turned off and dildo stops moving, but it stays inside of her.

"I bet those would look good in your ass," Donna says, rubbing it.
"No, only my Master can have my ass. It is his hole and his alone."

Donna gives you a shocked and surprised look.
You nod, letting her know that it is true.

"I see. Well, in that case..."

Donna adjusts Jenni's ropes and ties her in a modified hogtie.
She presses a vibrator to her well-used pussy.
She's going to punish her for denying the use of her asshole.
You don't stop it.

"You've got...five minutes and then I need her back. Don't worry- I have a person you can sodomize if you want."
Donna smiles.
