I was at my friends house one summer just hanging around, bored with nothing to do. He told me that he wanted to show me something but first he made me promise not to tell anyone. I quickly said yes and he led me into his parents bedroom.
I watched him as he pullled out a pair of his moms panties. He dropped his shorts and began rubbing his cock with the panties. I couldn't take my eyes away from his cock as he masturbated with his Mom's panties telling me how good it felt. Then he pulled out another pair and handed them to me. The silky feel of the nylon panties felt increadable in my hands.
I quickly dropped my pants and for the first time in my young life I began masturbating. The nylon panties really felt good sliding up and down on my cock. We stood there for a few minutes then lied down on his parents bed next to each other. Next thing I know he reaches over and starts masturbating me and I did the same for him.
We did this most of the day being too young to cum we could last all day till it was almost time for his parents to come home from work. We made the bed and put his moms panties back promising to do it again the next day.
