Bethany and the Professor are a match.

The man was annoyed at how nervous the young lady was.

It wasn't fun to watch her fumble with the lady's tits or half-heartedly suck on them with her eyes shut.

"Alright- you had your chance. Now strip!"

Bethany's whole-body blushes, but she has **** with a gun pointed at her.

She slowly undresses for the man.
She kicks her clothes away when he tells her to.

Her arms are tied next and she is told to lay down on the floor.

Her ankles are tied and then a rope line goes between the two to hogtie her.

The Professor gets his attention next...

He frees her from the radiator but keeps her tied up tightly otherwise.
She is rolled onto her stomach and given a hogtie.

"Oh- I'm out of white tape," he announces, "This will do."

Bethany is shocked as he takes a pair of panties from a drawer, shoves them in her mouth and then uses duct tape to seal it in.

"One last detail to fix..."

He retrieves Bethany's panties and goes to the Professor, removing her white tape gag.
A white sock is removed from her mouth and replaced with the panties, before more duct tape seals them in.

"Perfect," he says, looking at his work.
