This is a true story
About three weeks ago my dad and step mum finally broke up, it wasn't until about a week later that they actually moved out though. Anyway, my step mum and one of my two Step Sisters were packing up by the door, my dad was upstairs and I was in the sitting room, then, my other step sister came in, she is 17, with long curly brown hair, with quite big boobs. She very casually asked me to help her with her bags, to carry them to the door, so, I left the sitting room, and went with her.
When I was in her room, I noticed that there were no bags anywhere in her room, it was completely empty, I turned round to see she had locked the door, as soon as I looked at her she pulled her top off, and then her bra, exposing her beautiful breasts. I couldn't not look, she smiled at me and walked towards me, she then pushed me against the wall and unzipped my fly, I was already hard, she took it out and started to jerk me off.
I had almost cum, when she stopped moved backwards and started to take her jeans off, then her panties, she then laid on the ground, and started caressing her pussy. It was so hot, so I started jacking off. It wasn't long before we both came. Hot and sweaty, we put our clothes back on, and walked out. She left with her mum and sister about half an hour later, and text me 'I hope we see each other again soon'.
I will never forget this moment.
