Spying On Step Daughter

I’m obsessed with my grown step daughter,
She is 25 and moved back hime after a split with her boyfriend.
She has been home for two months and always walks around the house in her underwear.
I’ve become totally obsessed with her to the extent that I’ve bought and set up hidden micro cameras in her bedroom linked to my ipad and phone so i and spy on her.
What I didn’t expect was how many times a day she masturbates,
She has a naughty little routine going.
Every morning before she gets out of bed she humps her pillow flat on her front,
She always sleeps naked and I’ve sniffed and wiped my dick on that pillow many times.
On her days off from work she will use her vibrater on her clit with her legs wide open.
At night she has a long session watching porn rubbing herself she spends lots of time on her breasts pinching and squeezing.
I know every single thing she does even how she checks herself out in the mirror constantly.
I wank over her on camera all the time and even think of her while i fuck her mum.
I know exactly how her pussy smells and tastes because of all the times i have stolen her underwear to jerk off.
I’m seriously thinking about fucking her when her mum goes on her yearly trip with her friends.
I want her so much.
