Very nearly fucked my sister
20 years ago I very nearly fucked my sister, my grandad died and my mum invited my Nan to stay for a few days.
I was 21 and my sister was 17 sleeping arrangements were, you’re sleeping in your sister room, I remember arguing about this, why can’t I sleep on the sofa, mum said if Nan gets up and wants to relax in the living room she can’t if you are in there.
My sister had the small room, the first night nothing but arguing, I remember my mum coming in the room going nuts at us.
The second night we slept back to back, third night I’ve woken in the night with a big hardon facing my sister back, I couldn’t help it, I pushed my cock between my sister legs, I’m dry humping her, she had her knickers on and my cock is now pressed up against them, I remember pushing really hard when I was cumming, if it hadn’t had been for her knickers I would have been inside her pussy.
I did leave a nice puddle of cum over her knickers.
Luckily my Nan went back home the next day, the pair of us too this day have never mentioned anything about it.
