Fun on the lawn.

You take Sasha first, but make sure that Starla sees you dragging her naked body outside.
Let her wonder.

Sasha ends up staked out on the lawn, but you made sure to keep her tied from every angle. She can't quite settle in or get comfortable when she is pulled from so many different angles.

Walking away slowly, you let her stop and wonder what you plan to do next.

A few minutes later, she gets her answer...

You lead a naked and bound Starla out on the lawn to see her, a bottle of baby oil in her hand.

Starla is ordered to oil up Sasha's naked and bound body.
She's nervous, but also knows not to refuse you.

Reluctantly, she starts to rub the oil into her friend's skin, tentatively doing so at first.
You yell at her to really get in there- hold nothing back.

Her hands go to Sasha's tits, barely grazing them.
A few swats of the flogger 'loosen her up' and she does what you told her to do.
Her hands move to Sasha's pussy, afraid to take more flogging...

After you're satisfied, you hand the flogger to Starla and tell her to hit her friend.
She can't refuse you and softly taps her with the object.
Starla gets several hard swats as a 'reminder' for how she should do it.

She tries again, but she's not that good and/or willing to do it.

Pulling her up, you hold her with one arm while you flog Sasha right with your other.

You demand the code from Sasha.
She refuses, but she definitely has less fight in her than before.

"I'll be back to punish you later then. Remember that you could have ended all of this.

As for you, your punishment for not doing what I wanted right is going to be severe too."

You lift Starla and take her away from Sasha.

She's screwed.
