A large vibrator

This thing looks powerful.
This thing has heft.
This thing has batteries, so no plugs needed.

Mallory looked on in a bit of shock at the vibrator.

'Is he going to use that on me?!?'
"I'm sure you'll like it. Now how does this..."

He presses a button and the whole thing moves in his hand.
This scares Mallory a little bit.

"Don't worry- I can handle it."
'That's not what I'm worried about!'

He brings it to her at the end of the bed and slowly moves it into position.

As soon as it touches her pussy, she feels the pulsing and vibration.
She immediately reacts!

She starts to buck against the ropes, at least as much as she can.
With no way to get leverage, she's not going anywhere.

"I just need you to cum once for me."
Mallory nods submissively.

This feels right.
This feels natural.

Other guys in the past abused her body and tested her limits for photo shoots
(Like so: https://image.xfreehd.com/media/photos/212953.jpg

In contrast, her man was just trying to not hurt her.

That said, she was going to cum really hard any minute now.
Hopefully he knew when to let up.
