Stepdaughter

My wife had gone to bed early and i was having a wank to porn on my phone when my 23 year old step daughter came home drunk,
She sat on the sofa opposite me and didn’t even notice my erect dick hidden under a pillow.
Within a few minutes she was out cold,her tiny dress had ridden up to expose her white panties.
I couldn’t help myself and carried on wanking.
I got closer and took lots of photos.
Her panties were very see through and see was completely shaven.
I gently pulled them to the side so i could video her pussy and she didn’t even move.
I was so horny i was on my knees wanking with my head between her legs sniffing her pussy.
I came all over the sofa she was sitting on.
I then placed myself back on my chair to calm myself before waking her to go to bed.
Once I was alone I watched the video and pics and wanked myself again.
