I'm approaching 60 and have had a fetish for female sanitary protection since I was about 13 or so. My mother, sister and I were staying at my aunt and uncle's for a couple of weeks. I was about 14 or 15 at the time and wanked off 2 or 3 times a day.
My mother, sister and aunt had gone shopping and my uncle was at work. I stayed at home and amused myself with this and that. Soon I became horny and decided to have a look in my aunt and uncle's bedroom. I soon found something that made me extremely horny. It was several boxes of very large size sanitary towels (this was before plastic packaging). There were also a number of sanitary belts, but what nearly made me cum was a number of pairs of panties with a rubber lining in the crutch. I then noticed that there were several pairs of rubber pants and a rubber sheet. My cock was so hard. I was gently rubbing it as I looked at all this exiting stuff. Then much to my horror, a voice said hello. I was kneeling down at the side of the bed as I looked up in shock and saw it was my uncle standing in the doorway.
He said 'don't panic, they have that effect on me as well' and as I rose up on my knees I could see that he had his cock out and it was as hard as a rock and huge. He said that he had some things in his study I may like to see. We went along the landing where he opened a cupboard and took out a box. It was full of sanitary pants, belts and pads. Some of the pants were new, some were used. Same for the belts. All the pads were new.
He went on to explain that he did the same as me and asked if I had looked at my mothers and sisters stuff. For some inexplicable reason I never had, maybe the opportunity had just not presented itself. As he showed me all the pants we were both rubbing our cocks. He said that the reason he had come home was to have a look at my mother and sisters cases etc as he suspected one or both of them were on their period. He told me he had wanked off while looking at my mother's sanitary stuff a number of times in the past.
Although all the pads and pants were turning me on more and more, I was taken by the size of my uncle's cock. I had to keep looking at it. I asked him about my aunt's stuff and he explained that she had very heavy periods and the full rubber pants were mainly for wearing at night and the rubber sheet was to protect the bed. He said that my mother (her sister) also had heavy periods. We then went into the room being used by mum and sister, and he opened a suitcase. 'Bingo' he said as he looked at my mothers clothes and sure enough there was a part used packet of towels.
He said excitedly he had found some sanitary pants that had a stain on them and some clean ones. I was nearly cuming which he noticed. He asked if I had ever been wanked by another man. I said I had done it with some lads from school. He said he would do me if I liked. I nodded in approval. He said we should look in my sister's case, to see if she had any sanitary products with her. We opened it she had a pack of pads which excited my uncle a lot. He soon found a thing that looked like a jock strap except that the pocket part was made of plastic. He said that a lot of young girls were wearing these as they were a fairly new idea.
He said he had to cum and asked if I would like to do him. I took hold of his monster cock and started to pump him. After about a minute he started to buck and jerk and shot a huge load. At the same time he jerked me harder and I shot all over him. More stories to come.
