I Stole My Friends Panties

When I was 15, I was so horny all the time, I had this friend (let's just call her E) E. She had a gym bag in the classroom on the shelf. After school finished, I used to look through her clothes hoping to find some hot clothing. First I found a sock, I came in it so hard because it smelled like her (not the dirty feet, her nice smell).

After a week or two, I looked through it again, I found this beautiful black Calvin klein underwear, it hasn't been used. After I got home I was smelling it for a good 10 minutes, I whipped out my bulging cock and started rubbing it on my dick. It smelled so good. She is blonde with bangs, nice tits and ass. It was rare when I could see it because she usually wore baggy clothes. On my phone I got a picture of her face and as I was looking at it a came so hard it went all over the place. The sweet smell of her panties was so nice.

I still have it under my bed and I sometimes use it to masturbate. Should I feel guilt for steali g her oanties
