I had to drop some mail at my stepdaughters flat one day, when I got there she was at work but I let myself in with my spare keys. My stepdaughter shares her flat with an 18-year-old girl as hot as my stepdaughter is.
As no one was home I thought I might sneak a peak in her flatmates room. When I walked into her room I saw on the floor a hot little pair of g string panties and I couldn't help myself. I picked them up and I was rock hard in a second, they smelt so good I just had to jerk off there and then.
So I locked the front door and went back into her room and got naked,
it felt so good being hard and naked in her room playing with her panties. My cock was so wet with precum and it felt so good.
I came into her panties and left them on the floor like that.
Can't wait until next time
