Stealing My Friend's Sister's Panties

I am your typical teenager I jack off like 5 times a week and I like trying new techniques. One day I was at my friend's house. His sister is really hot, but she was out with a friend. I decided to go to her room and see if I could steal a pair of panties. When I opened her closet I was surprised at all the colors and types. I saw one of her bras-she is 36c. I took a really hot pink thong and just lied on her bed. I decided to be daring and jack off on her bed in her room. I put the thong over my face and began rubbing my 7-inch cock slowly, eventually picking up speed. This was my best orgasm ever! I shot like 5 globs of sperm. Afterwards I cleaned up and left, but I stole many more panties since then. This was my best orgasm ever!
