By the time I turned twelve I was constantly horny, so I would always try to find a way to jerk off as often as possible.
One day I had to stay with my Aunt. She is not very attractive or anything but she is very cool. She lets me do pretty much anything while I'm there. So she said she had to go out for a while but if I wanted to I could stay here and hang out till she got back. I knew this was a chance to jerk off so I told her I would hang out.
As soon as she left I was very excited, so I pulled out my five inch cut cock and began playing with it on the couch. Then I started to think about going into my Aunt's room, and the thought made me go wild inside. So I grabbed my things and headed for her room. When I opened the door it was dark and it smelled like perfume. The whole vibe I got from going in there turned me on so much I was out of my mind.
I walked around her room naked with my hard on sticking straight out till I found my way to her dresser drawer. I opened one of them to find her panties. I pulled the first pair I found out. Just touching it made me want to cum. It felt so unreal and so naughty going through her panties.
So I lay on her bed and began to rub them all over my body, especially on my cock and balls. Caressing her panties against the underneath of my cock made it twitch so much. Pre-cum started oozing out like crazy. I don't know how long I was lying there but I could not take it much longer. I could feel the cum edging it's way to the top of my cock. So I placed her panty over my cock and wrapped my hand around it so the entire panty was covering my cock and began jerking hard and fast. Then I shot my hot load into her panties without even thinking.
When I opened them up it was filled with my cum. I was pretty freaked out so I just hid them at the bottom of her dirty clothes.
But just thinking about her panties is making me wanna get off right now.
