It was a hot summer's night in Melbourne the temp during the day had reached 40Deg C and at midnight it was still in the high twenties.
My 30 year old step-daughter was at work till 1.00am as she works shift work and I was in her half of the house (Two living areas in 4 bedroom house she had the back half with her son) babysitting her son (although he was asleep).
I was lying on top of the bed with nothing on as it was too hot to be beneath the sheets and I was having a lovely dream of making out with my step-daughter. I became aware that I had a steamer of a hard on and that I had heard the front door close. I turned over onto my back as my door was ajar so that I could hear the baby, and pretended to be asleep. I had my eyes slightly open and my hand on steel bar of a cock slowly rubbing up and down and making noises as if enjoying myself.
Now I should explain that my step-daughter is 5' 5" tall very thin and petit with a nice size 12 AA chest, size 12 but, and is very lovely and hot to look at. She often turns me on in the summer time by what she is wearing with her low cut tank tops and tight shorts that hug her ass and show of her curves. And when she bends over I get an instant hard on at the site of those lovely tits.
Any way I digress. Liz came to my door to see what was going on and just stood there for a while looking at me slowly pulling my pudd. I her left hand go down the inside of her shorts as she watched me and she started to finger herself. She then began to unbutton her shirt with her right hand and start to take it of exchanging hands so that her top could fall to the floor. Then with her right hand now doing the job of her left she undid her shorts and dropped both them and her panties to the floor and stepped out of them.
