"Thank you, Masters."

Dee seems happy to submit to both of you.
You and Donna smile.

"Of course, you should know that Donna also submits to me. Right, ****?"
"Yes, Master."

She gets on her knees submissively.

"Now then, I think that it is time for ME to have some fun with you. Your Step-Daughter will help you tie you up and then watch me while I take you."
"Yes, Master," Dee says with a smile.
"Yes, Master," Donna says.

Minutes later, Dee is tied up suspended over a bed and you are fucking her!

She cums.

Alot!

While Donna is tied up and watching, you have Dee in a new position.

This time, she's laying on the bed, but her neck is tied to her legs, restricting her movement all the more.

She can't 'fight back' as you fuck her asshole.
The vibrator is there to drive her over the edge even more!

You recover your strength as you make Donna wait.
Dee lays in bondage as you plot how you are going to take Donna...
