Her husband.

Shelly was making a sign to you that she wants to act like she is not there.

"Who is there?" you ask through the door.

"It's Max, I rented this room. But I just can't seem to open the door." He says.

"I wish the door would open again. And that Shelly stays frozen holding the bag underneath her." You think.

You hear how Max tries again. And the door opens.

"Oh my god... It smells like pee up here. Shelly why are you holding that bad underneath...." he says.

He starts to walk up to her.

"Oh my god you peed in your own bag! That's disgusting!" Max says.

Max then notices the buttplug still in Shelly her hands....

"What the fuck is that up in your hand?" He says.

"Yes what is is it?" You ask her too.

"It's a buttplug. It's mine." She says.
