A few days ago i stopped by my dad’s house early in the morning. My 14 year old half-sister was taking the day off school and was asleep on a sofa in the living room.

A short while after i got there my dad asked if i could watch the house for half an hour while he went to the store.

As soon as he left i sat on a sofa opposite my sister and whipped my d*** out. I started m*********** in full view of her. Just thinking that she might wake up at any moment and catch me was so exciting and a part of me wanted her to.

She woke up a couple of times and i quickly stuffed my d*** back in my pants but i’m not sure if she saw or not. She hasn’t said anything.

I like to think she was only pretending to be asleep for some of it and was watching me jerk it while rubbing her p****.

What i really want is for us to m********* together. I want to see her c** and i want her to see me. I’ve seen several videos online of mutual m*********** and the thought of sharing that with my sister always gets me off.
