When I was a teen/early-early 20s I tried all kinds of things... of course a pringles can with sponges etc. stuffed around the edges. I can only imagine how many boys have tried this! My favorite was in my first apartment. Back then those "pringle sized" water bottles were popular. They were better than a pringles can due to the fact that if someone found one in a bedroom they would think nothing of it. Anyhow... I had several sponges that I used specifically for this purpose. I would sandwhich the sponges on the inside, and then take a dishwashing glove, the kind that had the long cuff... and push it in between the sponges all the way in except for about an inch which I would tightly place over the rim. It was as if they were designed to do so... fit perfect. And then of course put some kind of lube in the glove.
Watermelon & Cantaloupe Many years back, I read about it & decided to try it. The first time, I cut a hole into a watermelon with a knife. I tried to get it rounded & the correct size. It worked kinda,but not the best. Then I experimented with different sizes of drills until I found the best one. Drill the hole. Then chamfer the edges. I discovered that the melon also needed a vent hole in it so that you could push into it without the pressure building up & splitting the melon. When I did get in without a vent hole & managed to not split the melon, there would be a lot of suction when pulling back out. The small vent hole really made things better. A room temp melon would have a nice wet sloppy feeling, like a real pussy too.
Set the cantaloupe out in the sun for a couple of hours. Or heat it at low power for a short time in the microwave. Really nice when it's above room temperature.
I've used the orbital sander without sandpaper,of course. Also years ago rigged up a baggie cum catch system in the shop vac. Fastened a dildo to the workbench while I fucked the shop vac Awesome feelings
I’ve used one of those sanders with the small triangular head on it. I made a little sheepskin cover for it where the sandpaper attaches. It worked great for balls and cock. I might have to try it again.
I used to have the odd good time with a watermelon. They were warmed to the right temperature by t afternoon sun. .Cut a hole in the end of it a take a stick and mash a tunnel in it for your cock to fit just right. Set it on the tailgate of the truck and fuck away.
+1 for the triangular "mouse sander" So intense I had to do it while keeping my jeans on. Noisey though
+1 for the vacuum cleaner. The tube you are putting your cock into needs to be a little bit bigger than the girth of your cock head when fully erect. If you are too big use a short length of plumbers plastic pipe that fits you. It's not as much the sucking sensation as the way it vibrates the head of your cock. If you blow a raspberry, the vibration sensation you get on your lips is what you will get on your cock. It is really intense and instant. In the past I've come without even getting erect.
Back of an electric toothbrush head, on the backside of my cock right under the head. Sent little shockwaves down my legs and when I came, I came a lot, very intense.
I've used so many things as lube, all the usual baby oil, vaseline, ky jelly. But I've also used shampoo, nappy rash cream, coconut oil and my wife's cum. Used a rubber mould for chess pieces with lube, like a rubber pussy, easy to clean the spunk after as well.
