Waking up with your sister

As you woke up you saw your sister’s face looking back at you crying, you weren’t doing it but you could certainly feel it as if you were. Try as you might you cannot make her body move, maybe you’re dreaming but this seems so real. ‘What’s going on, why can’t I move my sisters body?’ You asked but no sound came out
“David??? Is that you? Where are you?” You could hear the mix of fear, panic and hope in your sister’s voice
‘Yes, it’s me. I’m in your body, but I can’t seem to control it. Do you know why?’
Your sisters body stopped crying and looked up into the mirror, wiping away her tears then you realised she was still in her body.
“They said you were gone, your mind disappeared in the transfer and the couldn’t work out what happened, are you saying your in my body if so what am I doing now” she grabbed her tongue with her left hand and blinked rapidly, you said that.
“Oh my god you are alive and sharing my body, I’m so happy that you’re not dead, I promise I will do everything I can to make you feel at home. First things first though we should let the doctors know where you are”

She spent the next few hours explaining what had happened to you and having tests done to the two of you. Eventually they believed her and let her take the two of you home. Once there she hugs your family, one at a time before going up to her room.

Once inside she locks the door and goes into her en-suite, she used to share it with your room but it’s all hers now. She starts to get undressed, putting her clothes into the laundry basket, you see her naked body again in the mirror. “I know my body is not where you wanted to be brother but I can try to make you enjoy it, I hope you will learn to love it”
she walked into her room and pulled a small tray from under her bed, it was filled with various different sex toys. ‘Uh sis what’re you doing?’ “Isn’t it obvious, we’re going to masturbate, though I will let you choose what to. If you don’t choose I will, I need this”
You thought for a second and said ‘lesbian porn please’ you felt her sigh as she laid on her bed and got her phone out, navigating to pornhub she brought up a few videos asking for your choice, once you chose one she took a vibrator out, turned it up to max and pushed it inside her. The feeling was alien but amazing for you, your sister was clearly uncomfortable watching this but kept going.
‘Stop, if you’re going to do this you should enjoy it to sis, put on something you like. I need to learn what you like not the other way around’
She stopped the video and searched for (hunky men fucking big women) and played the first one, this time you were uncomfortable but the sensations were so much better, she got it deeper, went faster and the eventual orgasm shook your world.

She passed out from the pleasure, you rolled over and realised you could control her while she slept. You walked to the bathroom and sat down on the toilet, you peed then wiped her dry, you turned on the shower thinking it might wake her up. You stepped inside and cleaned her body, it took about half an hour but you felt better for it.
Walking back into the bedroom it smelled of pussy so you put some clean clothes on and changed her sheets before checking the time, it was late afternoon so you left her room and went downstairs for dinner.

The rest of the day was quite surreal as you expected her to wake up and take over trapping you inside her but she didn’t, you pretended to be her and everyone believe you, when it was dinner time you had a smaller plate than she would normally have; saying you want to get in shape for your brother.
