Dirty knickers

So on Saturday I ended up taking some women home from the pub she must have been in her fifties but still good looking. In the taxi on the way home I had my hand in her knickers fingerings her the taxi driver must have had a hardon because she was making some noises but anyway I got her home and she jumps on the bed bends over and pulls her skirt up then tells me to rip her knickers off and fuck her hard.
My cock instantly got hard in my jeans. I quickly got out my jeans and tore at her thong splitting it in the middle making room for my hard cock. I fucked her hard for the rest of the night.
Anyway just now I am lying in bed I happened to look down the side of the bed and I found her ripped knickers. I quickly put them upto my nose and I could smell her musky pussy from her gusset. The smell gave me a strong hardon. My glistening helmet was sticking out my foreskin. I kept smelling them and I was quickly giving myself a wank. The smell was really turning me on before I knew it I was cumming hard
