She does.

"Yes- yes, I'll do it."
The trio share a look and smile.

Two of them leave to retrieve Iona and Reina, while the third slowly begins to untie Cheri.

'Sorry- I'm doing what I have to, ladies,' she thinks to herself.

A bit later, the trio are reunited...but not happily.

Reina and Iona are tied with their hands together up over their heads.
A long rope connects their wrists to a strong branch above them.
Rope is around their ankles and tied to a wooden stake plunged into the ground.
Their legs are spread wide.
For a final insult, a small stick is tied around their tongue, not allowing them to speak.

In contrast, Cheri has one hand tied behind her back and it is looped to a bit of rope tied over and into her crotch.
She can't pull that hand away or tug on something she does not want to tug on.

One of the Raven Cultists leans in and whispers instructions to the blonde.

"I have to prepare you...for them," she says solemnly.

She reaches into a jar in the hands of one of the Cultists and soaks her digits in some of the fluid.

She rubs Reina first, touching her neck, arms and stomach.
Cheri knows that they want her to touch the more intimate areas, but she's putting it off as long as she can.
