We also wanted have rubbers on hand in case we ever got "lucky". (Yea, right!) Because we were too chicken to attempt to buy one, we decide that we could make some by making replicas of our dicks and then coating them with some kind of rubber. We came upon aquarium sealer and it seemed like it would be perfect for the job. We made tinfoil molds of our cocks and then poured wax into them. This worked alright but there wasn't much detail. It was still fun having it around though. We coated the wax copies with the aquarium sealer and waited for it to dry. We then peeled back the home-made rubber and tried to put them on... They ripped right off! Oh well...
This got me going about making a better detailed copy of my dick though. I had the idea to do it differently and decide I would do it the next time my parents went to the cabin. The following weekend they did just that and I got out the tools. I clipped and shaved all around my cock to be sure there wasn't any hair. I then mixed up a large batch of Plaster of Paris in an old gallon ice cream bucket. I then took a large piece of plastic and poked a hole in it to shove my dick through. Once I had my dick and balls through, I laid down on the floor and poured a small amount of plaster onto my stomach to the base of my cock. I was so hard by all of this that I had to have a layer of plaster down between by rock-hard cock and my stomach or I'd never get a cast of the top part of my dick. Once that amount of plaster was semi-hard, I poured the rest of the plaster all over my cock and balls. I forgot that plaster gets warm when hardening and this only made my cock get bigger and harder! I didn't think this would get so erotic but the tightness and warmth was getting to me. Of course at 16 my hormones had kicked in at such a heavy rate that I'd get horny just about every 10 minutes anyway! Fortunately I poured the plaster thick enough not to crack from my cock's straining to get bigger. Finally the plaster was hard enough that I decided to take it off. I didn't realize what a tight fit it would be. It felt like a super-suction blowjob! Every time I'd try to pull free, the cast would hang on tight and give me the best feeling. I could not get it off before I got off! And that happened after a couple more pulls. It was unbelievable, I just kept spasming over and over with warm flashes up and down my spine as I came and came. I finally removed the cast whole and in one piece and it looked perfect! I washed it out and let it dry for a day or so and then poured in the liquid latex moulding compound. It is carried at many hobby stores for people to
