Sam, but Ruth takes her punishment.

"Sam. You're just too timid to be a good Sex ****," the Lead Trainer explains, "But we'll fix that. I think a nice DP will do the trick."
"No! Please don't! I'll do whatever you want," Sam replies, begging desperately.
"I have spoken. Unless you want a third cock, you'll do what I say."
"Yes, Master. Please be gentle."
"We'll see. Come here, Vivian. It is time to put that cock to some more use."

As Vivian approaches again (seemingly not bothered by this course of events), a voice speaks up.

"May I please take her punishment, Master," Ruth says.
"No, I can't let you," Sam says, leaning in against her cheek.
"But I can," the Lead Trainer replies, "And I will. Good initiative, ****. Of course, I think that you just wanted a DP."

Meanwhile, the two other Trainers are still fucking AJ (on top of Sandra's prone body) and Carol (taking it doggystyle as she's **** to make-out with Sandra). They were at orgasm moments ago, but have held on about as long as they could.

"May we please cum, Master," AJ cries out.
"Please, Master," Carol adds, "We're about to burst!"
"*sigh* Very well. Cum, you filthy sluts!"

The pair cry out as they finally get release, the tension built up nearly to a boiling point! They are screamers!

Back at the Table, the Lead Trainer is now laying on it. He has **** Ruth to climb on top of him and mount his cock. Sam, Liz and Jaqueline just look on as Vivian moves into position.

He spreads Ruth's cheeks as she sits on him near the edge of the table. Vivian moves in now, pushing her strap-on cock back into Ruth's asshole! He wishes that he could fuck her ass, but knows that his massive member might stretch it and lower her value.

The two other Trainers approach the trio currently unoccupied and **** them down to their knees. They are **** to clean their cocks, sucking up Sandra, AJ and Carol's juices!

"You two can fuck whichever ones you want now," the Lead Trainer says, "I'll be busy with these two for awhile."

The mute pair smile and consider who to take next...
