I started to realise when I was about 14 that I was getting nice sensations in my penis and that sometimes it was slightly harder than at other times. My parents were both very narrow-minded about everything and had told me nothing about sex or adolescence at all. I only had one brother who was a lot younger than I was so I couldn't discuss things with him.
I was aware when I was growing up that my Mother would sometimes refer to 'being ill' and would make a point of going shopping and telling me to wait outside when she went into a pharmacy every few weeks. She would always come out cluching a large brown paper bag containing boxes of things which she made a point of hiding in her wardrobe as soon as we got home.
After a while I noticed I was getting curious by her movements each month and her dashing to the bathroom at times with something clutched in her hand. A few minutes later, if I stood within close range of the bathroom door, I could hear the rustling of a paper bag as she appeared to be wrapping something up. I gathered by looking in a book in the library that she was having her period at these times and the purchases from the pharmacy was for sanitary towels (pads).
One day I was home alone and my curiosity got the better of me and I went into her bedroom and searched in her wardrobe. I found three packets of these looped towels and 2 sanitary belts and 3 pairs of sanitary knickers. I did no more than rush into the bathroom with them and got undressed. I put one of the belts around my waist and attached one of the towels to it. It felt so good and so soft between my legs. I then put a pair of the knickers on and pulled them up tight up against my rapidly growing penis. I was getting more and more aroused by the second. I slid one hand inside the knickers and rapidly rubbed my excited cock. Then I pulled another towel from the packet and wrapped it around my cock. The feeling was undescribable. Something I had never experienced before.
I continued rubbing for about ten minutes until I reached the point of no return. I looked down inside the front of the knickers and saw my cock shooting cum all over the sanitary towel. That was my first time and an experience that I will treasure forever.
