I use to always get a hardon as a kid looking at the drugstore displays. They were hot. One even had a manikin holding a bag and the nozzle drooping from the hand. It was in the front window display of the old drug store. I think maybe someone might have done it as a joke. My bf and I use to walk by the store front and laugh.
The old Sears & Roebuck catalogue was fun too! I use to get such huge hardons looking at the enema gear. I had to keep it centered on my hard dick as I looked through the catalogue in my parent's living room, with my finger in the car and tool stuff so I could do a quick page flip if someone walked into the living room.
I also use to look in there in anticipation of them being away the next day and what fun I was planning for my asshole and my mother's enema gear, which I always removed and replaced ever so carefully. I became an expert in laying the hose back on the top shelf exactly as I had found it!
Oh, I use to plug that old toilet up so much with my expulsions and toilet paper. It was a slow flusher.
I still stroll past whatever enema gear there might be in stores today, but not much. I still start to get a hardon. In my youth I had to be sure I had my dick down and secured in my briefs in stores where I might see enema gear, it was instant hardon for me, like really hard, surprised my dick did not rip out through the front of my underwear and pants. I loved enemas, anytime I was alone I got the enema bag out, and they were large! I use to fill the big old red bag up twice, I must have been getting at least 3 qts. as I got older. It all felt so good, and then when I was able to cum it was quite an explosion and exhilarating feeling.
My cum seemed to shoot out about 3 feet! And my expulsions were also incredible, LOL, felt so good! I held it in as long as I could, slowly stroking my super hard dick all soaped up over the washbowl right in front of the toilet, with a washcloth pressed over my asshole so I did not blast out all over the place. I did slip once with the washcloth I was so excited, a huge huge mess all over the toilet and walls. I was lucky I had lots of time to clean it up before my parents got back home! Fortunately all of the walls were ceramic tile and not paint that might have stained easily.
