My neighbor who is a year older than me which would make her 19 is a very sexy girl. I have always fantasized about having sex with her. One day when no one was home at her house or my house I took the spare key that we have for her house and decided to go take a look around in her room.
As I was exploring I came upon her panty drawer. As soon as I saw all the thongs and g strings I immediately became rock hard. So I decided to masturbate right there in her room. I took off all of my clothes and laid down on her bed and started to jerk off. My dick was so hard at this point and it felt so good to jerk off. Right as I was about to cum I took out one of her sexy panties and came all over them. Now when I have the chance I go over and do the same thing but sometimes I jizz on the floor or her bed so I leave my mark.
