Fucking my sister in-law

My first wife's older sister and I had got along really well. she wasn't married or had a boyfriend at the time.
So one day I stopped over at her place to pick up some of my wife's things that were there and she asked if I would like a coffee (I said sure). as we were sitting there I couldn't stop looking at her cleavage, she had on a low top. as we were talking I started to get horny and in my mind I thought it would be great to fuck her. so I kinda
changed the subject to more sexy talk. I could tell she was getting kinda hot, as it went on I kinda seduced her into how nice it would be to have sex and we don't have to let her sister know. she was a bit hesitant at first, but I think in her mind she kinda had a thing for me.
So needless to say we both got naked and fucked our brains out! the only thing that I really remember is it was just like fucking my wife, but it was the older sister......they both seemed to feel and fuck the same. only the older sister had bigger tits, same kinda nipples as her sister and her pussy seemed the same except her pussy was shaved and so smooth.
