crossdressing boy

When I was 14, I was sick and off school for a month. Both my parents worked, so I was left at home alone.
I had seen porn mags and had learned to jerk off from a couple of friends at school. I loved it and would jerk off every time possible.
My mom left for work later than my dad and I saw her often in just panties and bra coming out of the bathroom before she would dress and leave or work. She was about 5’5″, just a little chubby with big breasts and big nipples. I had noticed her hard nipples when she was in a bathing suit. My mom was often in my mind when I jerked off. Not only did I think of her but so did my friends, the ones that taught me to jerk off. We all had pics of our moms in bathing suits and when we got together we would put them on a coffee table, cover them with a piece of transparent plastic to protect them and jerk off on them. We would see who would cum the fastest and the most. We even licked off the cum pretending we were licking our moms clean after we fucked them. One time the rule was that the guy who came the last had to lick all of our cum alone off the pics. I lost on purpose just to taste their cum. They laughed as I licked but I did enjoy the taste.
One day she asked me if I could do the laundry to help out. Having little to do I said that I would. After she left, I went to start the laundry and noticed some skimpy panties and bra that I had never seen her wearing.
I picked them up and got a hard-on right away.
