She gets a different kind of stimulation.

She shook her head 'no' quite vigorously.
You told Jenya to press the vibrator back against her pussy.

The vibe caused immediate discomfort...

You smiled and told her to stop.

"I'll give you more later," you say, "It is your turn to cum, slave."

You pulled Jenya to her feet and dragged her away.

Jenya isn't happy, but she couldn't exactly resist you.
That rope collar was a good motivator.

She was tied up at the end of one of the nearby Stairs.
You tied her legs apart and she was held tight.

About 20 minutes later, you returned to where Jenni was.
You hid something from her sight.

"No more vibrator, right?"
"Please no, Master."
"Very well. You look a bit hot out here. Are you?"
"Yes, Master."
"Let me help you out then..."

You took the bucket of icy water and dumped it on top of her!

"That better, dear," you asked sardonically.

You walked away with a laugh.
