First time with aunts panties

The first panties I remember playing with were my aunts when I was about 15 yrs old. It was when I remember wet dreams started occurring and learning to masturbate as was feeling horny like most teens at about that age.
I used to stay with her for weeks at time during school holidays. She was a curvy woman with pretty face, with dark shoulder length hair and wore satin type panties of various colors.
She had just finished showering and her clothes were on the floor of the bathroom and she had gone to her room to dry off. I went in there to use the toilet and I was drawn to the pile of clothes on the floor and her purple satin panties in the middle. I picked them up and was looking and feeling them and became instantly hard. I dropped my pants and started stroking my cock and held them against my face, smelling her scent and was soon cumming all over the bathroom floor.
I quickly wiped up my cum from the floor with toilet paper and put her panties back as I found them.
This was the start of what would end up being an ongoing lust for her panties and her finding out about what I was doing with them.
