I worked at a service station and one of my jobs was cleaning the bathrooms when we closed for the night, I had noticed four girls I think from the local Collage go into the girls bathroom and they were there for quite some time. When I went in to clean up I found out what had taken them so long, they must all have been on there menstrual cycle and wearing dirty pads, as I did find four blood soaked pads in the waste, but it was what they had done that got me so fired up. Seems they all wiped there pads all over the walls before throwing them in the trash. The smell was so strong and I got so hard I just had to take my cock out and I almost did not make it; I shot cum all over the place, figured that would be it, but it did not get soft, and I still seem to have this desire to masturbate.
I picked up one of the pads and held it up to my face and the smell was so good, I just had to lick the pad, even knowing they had wiped them on the walls. I held one up to my nose to smell and stuck one in my mouth to suck on, my cock was just sticking straight out and dripping pre cum for a little bit but then as I was smelling and sucking on the two bloodiest pads I ejaculated all over the floor. I actually came three different times, and made quite a mess on the floor. I finally had to stop and clean everything up as the owner had knocked on the door and said he was leaving and to make sure everything was locked up when I left.
After this I did not have much chance to repeat this, although I tried when ever I could to get my sister or my mothers pads when they used them, darn it my mother burned them in the stove so I did not get many until later on when I was visiting my soon to be step daughter. I was helping her put out the trash and happened to grab the waste basket from the bathroom, as I was dumping it into a trash bag I noticed the rolled up pads in there covers. I started to tremble all over and my cock was dripping pre cum and making my panties wet. I managed to grab five or six of the little rolls and stuck them into my car, I wasn't sure but thought she seen me do this, but she did not say a word. When I got home I took them out and unrolled them and it was just like before, I got so hard and pre cum was dripping, I smelt them and actually came without even jacking off.
