The TP tube -- one thing I tried a few times, then found other / better ways.

The perfect-cylinder shape isn't as good a fit as a hand or a cunt even with a bag or lube (maybe it can be done better, dunno) and it was always either too loose or tight, plus some cardboard chafing.

Mostly it was the idea of penetrating something that size. A mind trip.

Just tried the toilet paper tube. Not even close to getting my cock head in. If I could get the head in it might be fun as it's about the same length as my cock.

The TP tube is probably the most common thing for boys to experience their first fuck. It certainly was for me. I remember putting my soft cock into the tube to rub it on the inside, then watching and feeling as it swelled up and filled the tube--so much so that I could not pull out until I was softer.

Had the same problem have you tried using a hollowed out cucumber? It's awesome a little messy but worth it.

That was something to play around with for me when I was younger. Go in soft and slide it around. It's smooth enough on the inside. The edges did grab a little which wasn't great until after you came and could feel all the chafing you did. It was interesting to get fully erect in it so my dickhead was sticking out and the shaft was encased. It kind of isolated my glans. Shit I want to try that again sometime soon. Be good with lots of lube on the head.

I remember sticking my soft cock into a TP tube, but when my cock started getting hard, I pulled it off, because MY cock has an upward curve when I get a hard-on and when that happened I was in a "bind" LOL, but it was fun while it lasted.

I think most guys have tried putting their cock in a toilet paper tube at one time or another, some with success and some without success! Blest are those without success!

I'm glad that I'm not the only guy to paractice fucking with a toilet roll tube pussy.
When I was about 12 or 13, I had a similar age girlfriend that lived in the little town where my grandparents lived. We hung out all the time when I was there in town. This was still in the days of no indoor bathrooms in my grand parents house, so we had to use the outhouse. We had a fairly nice two-holer and we often went in together. I liked to look at her 12 year old pussy and she liked looking at my as yet used, virgin cock, intreiged her too. I don't think either of us really expected to try actual fucking, but she asked me what it might feel if I stuck my cock into the toilet paper roll.
I have the feeling that a little bit older guy she knew had played with her little pussy and I think he talked her into playing with him or jerking him off. After I got my cock into the tube, she wanted to hold it through the tub and jerk me a while. I had not cum up to this time, but knew it sure felt pretty good. We finished wiping ourselves and went on out to play. Many times after that I used the paper roll again and have shot many loads. One time when my wife and I were camping and used an outhouse together, I showed her how I first jerked out a load using the paper roll. Her comment was that she sure had a better thing to have me cum into, that was a lot more fun.

Toilet paper tube would be way to small to try, but have used a warm banana peel and it is AMAZING!!!!

Some how I feel most guys have tried jerking off in a toilet paper tube and am convinced that more succeeded then have admitted to it here. Those that had success I have to commend you for being honest and for being conservation minded by not wasting the paper tube after using the last bit of toilet paper. No better way to help save a tree then to reuse it's material in a pleasurable manner.

Reminds me of when I was 12 and my GF and I would make out like crazy. Nothing below the waist, but I'd rub her tiny boobs and we'd make out till our lips were chapped.

One night on the phone were were talking sexually and she said she loved kissing me and asked how I got so good at it. I told her I just did want came natural. Then she said, "You need to practice for next time we're together". I asked how and she said, "Use a three liter Coke bottle". I thought she wanted to fuck, so I got a bottle, and tried to put my dick in it. I told her, "It won't fit" and she said it would so I kept trying. Finally I said, "My dick won't fit". She starts laughing and said, "No, practice sticking your tongue in it!" LOL!
