You trade him for Donna

"Fair point. You have worked hard today. Here- you can have this bitch," you say, "I know who I want."

You two move the ladies into place...

Jenni is placed face-down in front of Jenya's pussy and starts licking.
A pillow is propped under her stomach/ass area in order to prop it up for Donna, who leans forward and starts to lick her.

The two of you share Darling for a minute or two, making her suck both of you for a bit to lube you up.

Satisfied, you go up to Donna and push your cock into her pussy. She grunts, pretending to be upset at this.

You start to fuck her as you glance over at your friend Sarge…

He's got Darling riding his cock while sitting his lap. She has to stare at him while she does this (secretly by her request).

You lean in close to Donna as you fuck her...

"I have big plans for you tomorrow. One of you kinky bitches brought a strap-on to use, so *you* are going to use it on your friend here."

Donna pretends to be upset. Of course, you know that this is her strap-on. She's dominant with women, so this is a must-have.

"That's not all. When I'm bored of that, I'm going to tie you up nice and tight.
I saw a lovely pillar outside with your name on it..."

"I want to see how good you are. If you can make your friend here cum, I'll give you a treat tomorrow.
I know that you and your friend Jenya have a little something going on. I saw the looks in your eyes. I saw how protective you were of her this morning.

If you make me happy, I'll let her play with you a bit tomorrow..."

"Now let's see what you can do. Try not to be too distracted," you say, punctuating your sentence with a quick spank.
