I went from using a 2 1/2" diameter Dildo to a 3" diameter Dildo about 1 1/2 years ago. I got to where I went for the 3 incher every time and the 2 1/2" sat in the drawer. I was interested in desensitizing myself a little bit deeper. I looked at various porn stores, and even looked online. I couldn't find the toy I was thinking of. I wanted a 10" deep Dildo that could squirt. Not only that, I wanted one that could also squirt Anal Ease. So I took the 2 1/2" Dildo to the garage and put it on the work bench. I went upstairs and grabbed a bit of that thin tubing from a fish aquarium set-up that failed. I went back to the garage. I looked and found a piece of 3/8" soft copper tubing about 15" long. I used my Cutting Torch to heat the piece of copper tubing. I shoved it into the center area of the Dildo, on the top side, just above the nut sack. I had to heat it up a few times to get it all the way to the head of the Dildo. I pulled it back out, cleaned it, heated it, and shoved it back through, all the way. I let it cool down. I shoved the piece of the plastic tubing through the copper tubing, with extra hanging out. I removed the copper tubing, and left the plastic tubing in the Dildo. I cut the tubing off, just inside the head of the Dildo. I left about 24" or so hanging out the back part. I brought a tube of anal ease to the work bench. I removed the cap and drilled a hole in it slightly smaller than the plastic tubing. I forced the tubing into the cap. I screwed the cap back on to the tube of anal ease. After getting both of my Dildo's set up in my private outside area, I gave myself an enema. After a few minutes on the toilet, I opened a new tube of anal ease. I inserted it into my hole, and used my butt cheeks to empty it in to what I call my canal, just inside the butt hole. After about 5 minutes, I went out to the back yard with my camera on a tripod to get some good pictures. I mounted the 2 1/2" Dildo and squeezed on the tube until it was empty. I worked the 2 1/2 incher for a few minutes. I changed to the 3 incher and worked it for about an hour, hopping off and on, and taking pictures. I love looking at pictures of me having this huge Dildo being shoved up my ass. The modified Dildo worked well. After I was done abusing myself, I cleaned up my toys and put them away.
The next time I got the 2 1/2 incher out, I noticed that it had a bit of an off smell to it. I didn't realize that there was a bit of excrement in the end of it. It is definitely not a good idea to have a toy that is not THOROUGHLY cleaned, to be put inside me. From now on, I make sure that the tube is well cleaned before using the modified Dildo. It's a nice tool though. I still don't use it that much, since I fell in love with my 3" diameter Dildo. After I get done with Mr. Huge, and get him cleaned up, I give him a kiss on his head, tell him I love him, and put him away until next time.
Oh. back to the modified Dildo. I still use it on occasion. I keep in mind that there's a bend in the road, about 9" inward though. So even though I have the modified toy, it concerns me to use a desensitizing lube that far inward, because I'm afraid of hurting myself and not being able to tell of it until the stuff wears off. Although it's a good idea, and although the toy works as I desired, I'm still not totally sold on it. Thanks for reading my post on my modified Dildo fabrication and experience.
