Amnesia
A girl walks in and sits down on the bed.
'You're awake! Oh sweetie, thank goodness. I was so worried about you!' She leans over and kisses your cheek.
'Whu where wh,' you mumble, still exceedingly groggy.
'What's that sweetie?'
'I - where am I? Who are you?'
'Oh goodness, you must have hit your head harder than I thought! You honestly don't remember? Well sweetie, I am Chloe and you're my little pet,' she giggles. 'Well, girlfriend technically, but honestly I use and abuse you too much to really say we're equal.' She laughs again.
'Wait, what?' Your senses begin to return to you and you struggle to sit up, wide-eyed with fear.
'I like hurting people, you like being hurt. And denied. And humiliated. So I abuse you. It's fun.' She looks at you as if you're being dumb.
'I have no idea who you are!'
'Shh, sweetie, it's okay. Hey! Hey don't try and fight back.'
You rise up and try to overpower her but you're still finding it difficult to coordinate and before you know what's happened she's stripped off your panties, whipped out some pieces of rope and begun to tie you up. You fight and try to scream but it's futile.[Tie or tape your ankles to your thighs and your knees so they're spread apart.]
'Shh, sweetie, no need to talk now.' She uses your panties to gag you. [Push panties into mouth completely, then use tape or rope to keep them in place.]
