Electricity and flogging.

"That lovely little nub in your asshole is multi-purpose," Donna says, "Let me show you."

She turns on a power pack and electricity surges through the cable and into the metal plug in Lola's ass.
She cries out into her gag.

"Are you saying that it's on too low? Let me fix that for you."

She moves in closer to her face to see the results...

After she pushes the power past 30 (you set a limit for her, since Lola is going to be sold), she gives her a brief respite.

She's not gone soft though.
She's getting her whip.
She takes a rope and hooks her head gag to her ass 'hook,' forcing her ass and head up sharply.

"I like a red ass better than your white one!"

After a few long minutes (which must feel like an eternity!), she stops.
Again- she can't damage Lola too much.

"I'm not all bad. Let's make you cum...until you ask me to stop."

Donna brings out her favorite vibrator and press it into Lola's pussy.
She cries out in orgasm!

Lola cums again.
Donna doesn't let up.

Lola cums again.
She tries to ask for mercy, but her ball gag stifles that.

****, she looks at you, trying to find mercy and escape.

Hmm...should you?
