Her boyfriend (with a twist!)

Ashton was scared by being stripped and tied to the bed by the spirit.

She was nervous as the door opened...

She was then relieved when her boyfriend Josh walked through it.

'Oh thank God. Now untie me.'
She couldn't say this, however, due to the gag.

He walks towards the bed, but...

Suddenly, the door behind him slams shut.
He doesn't react.

Instead, he starts to strip his own clothes off mechanically.

"Mmmosh?!?"
"My name is Clarence," Josh says in a voice not his own, "This was my home. I was set to marry my sweetheart Bernice.
However, I was drafted in WWI and died on the battlefield.
I never got to make relations. I died...unfulfilled."

Ashton is freaked out.
A ghost is possessing her boyfriend.

"However, I'm not the one who did this to you. That was Bernice.
She died in a gas leak at this house and regretted that she never got to make relations too."

A lady ghost did this to her?!?

"In fact, she has a request. Will you listen to it?"
Ashton nods nervously.
