Rape sister but will she recognise me ?

Even if you’ve fucked your wheel chair bound sister before it’s still rape.

Sisters been in a wheelchair a long time now. I’ve written before about her MS
Now she’s married but not happy as he doesn’t fulfil her desires.
I was on my way to USA without anyone knowing. My mission was to cheer up my sex starved sister.
My Mrs was away and I had been getting very black WhatsApp messages from sis complaining.
So I knew her old man was going to be away For a couple days so I planned a surprise visit to try and cheer her up. Kay and I had a sexual past but that was stopped mutually when we both married. I was about to break that period of chastity.
I knew Kay had a fetish about rape. But it had never really worked when we tried to roleplay. She knew me to well and if it was a Tuesday evening she knew it would be me coming by as I always did when she lived back in UK.

Fast forward and I’m parked in a rental car two doors down from her house.
I’d been before so knew the lay out also knew key code for key safe that let in her paid help.
So about eight pm a dark wet night I entered via a back door took I’ll my coat and put on a ski mask.
I could hear the tv on in the den a room at the back of the house. Going down to the basement I turn off the power to the ground floor then moved up to the kitchen. I had picked up Kay’s phone that was on charge and pocketed it.
As predicted she wheeled herself into the kitchen in search of the phone.
Kay was one for talking to herself and she was cursing the power company.
As she passed me on the dark I put my arm around her neck and covered her mouth.
She went batshit crazy. Flapping her hard to control arms about like she was trying to fly.
I said nothing.
She was trying to scream but could not make a sound. I said nothing. As she subsided I slowly released my hand and she retried to scream. Again I put my hand across her mouth harder this time.
I slid my other hand down the front of what she was wearing. A towelling dressing gown with pyjamas underneath.
First I cupped her tit outside her top and she froze for a second before fighting again.
Moving my hand inside her top onto her smooth if a little saggy tits. Her head was rolling from side to side. I just squeezed them tight and growled in her ear.
I hadn’t hurt her yet but she was scared.
Again I slowly removed my hand from her mouth and moved it to her throat.
She got the message.
Not a sound came from her but for her heavy breathing. I pulled her head back by pulling her hair she squealed but not loud.
She couldn’t make out who I was and I wasn’t sure how she would react.
I had practiced changing my voice but wasn’t sure she wouldn’t see straight through me.
I took a chance and said “where’s the money?”
Like I was here to rob the place.
She started to tell me her purse was over there and and some money was in the dresser in the study, talking at 100 miles per hour.
I made a show of emptying her purse on the counter and taking the cash and her car keys.
I wheeled her straight to the study which I thought might have given me away. How did I know, in the dark, the way to the study!
I asked her to show me and she stuttered as she told me where it was.
There was a few thousand which I thought I’d keep as it had cost me to fly out here and I had plans for the week to come. Anyway her old man deserved to pay for me servicing his wife.
I pulled her by her robe out of the wheel chair and sat her on the desk laying her back with her sad legs hanging over the edge from the knees down.
She was fearful but not crying. Shaking and still calling me all sorts of names.
Putting my hand to her throat I pulled open the gown and undid the two remaining buttons.
In the borrowed light from the street lamps I could see where she had been sunbathing, leaving small white triangles highlighting her nipple area. They were as I remember. Large but not long. And just like our mums.
I squeezed her throat as I sucked on her nipples. She fought hard but the choking effect of me squeezing her throat shut her up.
I raised myself and pulled the cord on her pyjama shorts. Pulling them and her knickers off in one.
Her pussy wasn’t as I hoped wet. All the stories you read the victim is sopping wet and begging for it. Well that wasn’t the case. I couldn’t go down on her and keep ahold of her throat so I undid my belt and dropped my trousers.
She couldn’t see but the unmistakable sound meant she knew exactly what was happening.
She fought but as removed my glove with my teeth and spat on my free hand she knew what was about to happen.
I rubbed the spit on my cock and offered it up to her. Sliding it up and down her slit trying to make her more receptive.
Pushing in she gasped and called me everything you can imagine and more. I was slowly getting a rhythm going when I saw lights from a car swing into the drive.
Hastily I pulled out and grabbing her dressing gown cord I tied it around her mouth. Tight knowing she wouldn’t be able to untie it with her MS cursed hands.
Out the back door into the rental and away.
Apparently her old man had tried to call her and couldn’t raise her so he sent his brother around to check on her.

Would he be her saviour?
Did she recognise her attacker?
Did I leave clues?
Time will tell I guess but I think this is unfinished business
