My Friends Sisters Panties

About a year ago my friend went away on vacation for about four days so I had to take the dog out and all that stuff during that time. When I walked inside his house I found a dirty laundry bin at the bottom of the stairs. As I walk on by I saw a thong of my friends sister who was 16. It was pink and was so nice. After I quickly let the dog out, I rushed upstairs into her room. I took all my clothes off and layed naked in her bed. I got worn clothes from her laundry which included a bra, thong, shirt and pants. I put a pillow in the shirts and another pillow in the pants. I then put a picture of her face near her bed. I then started masturbating with some of her hand lotion to her clothes and soon started humping her clothes (which was like a life size version of her). I even sprayed some scented thing she wears. It felt so amazing I cummed all over her bed. I felt so weak because of it being such an intense orgasm. I did this the next couple of days, but one night I tried her mom's things!
