Biggest thing you've had in your rectum?

My largest sextoy is Doc johnsson ACE of Spades

Its 7,5 cm in diameter.

I also use a small inflated pvc ball that is not inflated so hard

So I can squeeze it a bit to get a bit smaller and not complete round when I insert it.

Then it became round again inside my ass.

Its such a wonderful feeling to be filled up with that

And slowly work up bit by bit to press it out again.

The ball Is a bit over 8 cm in diameter.

For now it's canine-type dildo: 17 cm long, and 4.7 cm knot.

It's not the end though - I'm working up bit by bit)

@stiknclikit I used to do the same with the handle end of the bat. Sometimes I would use a condom and sometimes I would use plastic wrap. Once that knob and handle were inside me I would put the head of the bat on the floor and then move my body so as to fuck myself in the ass with the bat. The way the knob at the end of the handle would hit my prostate would give me extremely intense hands free orgasms. I would worry my legs would give out and I would collapse and impale myself on the bat, it was so intense.

I've had many very pleasurable experiences with the handle end of a baseball bat. The knob drives my ass crazy!

My wife’s four fingers up to her knuckles!

My friend's just over 8 inch, rather thick, cock full length. Otherwise, the "silver stallion" rigid sigmoidoscope.

2" diameter double-headed dildo. It was a little too big.

Much like @Rigel , my wife's four fingers and thumb to the palm. Couldn't get past that point (yet).

@timberwolf421.............'yet' 👍

.

My wife's hand past her four knuckles and just past her wrist.

Longest? Dildo that is 14 inches (35.6 cm) long and 2 inches (5.1 cm) in diameter

.

I have this all glass toy that has a ball on the end; it's about 10 inches long with a handle. The ball at the end is the largest part, once it's past though, it really opens you up! Feels great.

My wife likes to insert various objects into my rectum as part of our play treatment. The largest to date is a silicon butt plug 2.5" in diameter. Also, a 2.75" plug made from a softer material. Have a 2.8" glass plug that I hope to be able to take some time. Wish I could get wife to insert her hand into my rectum but have not been able to get her to try yet.

Still using a 8 oz water bottle made smaller so it’s not as long covered top with wax shape like a suppository and use

It feels amazing as it goes in deeper use lots of lube ( J or K) and practice and it could be the best suppository you ever had

Many things but i inserted 2 family size ivory soap bars after a hot enema. Took alot of stretching pegging my ass then i forced one bar in and the second was soo hard i kept expelling my enema so i pushed hard and It hurt but went completely In past the spincter. I left it in 20 mins till my ass loostened and was an open hole for all to see

It was a really big cucumber, about 25cm long and 7 or 8 cm in diameter. It was really hard to insert and my hole was really stretched that day.

I originally had a medium Doc Johnson butt plug, many years ago. I really want to be able to gape enough for a glass bottle

I like length. The longest toys I get into me are 18" plus. I recently got a 16 " king cock thick double dildo which completely disappeared into me. I was popping it in & out just using my ass muscles, just the tip. My ass lips were really sensitive. Till I had the most wonderful anal orgasms. I also used to have a Dick Rambone which I sank down to the balls on. I've got to get another Rambone one of these days.

A large plug. The feeling when it finally slides in is wonderful. Takes time to get there though.

I've had a !0" dick in me and it made me forget about all the other things that I have put up me.

Rambone dildo. 2.5 inches wide and I get it about 10 inches deep.

Hmmm... a lover's hand, to her elbow? And I believe her reply would be the same.

I had never measured until I started reading this thread.

I am currently holding a 4litre coffee enema and will stretching my hole with an eggplant.

It is 26 cm ,around 12 inches in circumference.

I have had a number of hands ,but it's taken decades to get here

Four inch diameter butt plug and dildos. Wife gave me hard fistings in the past. Lost her not too long ago. Was working up to 4.5 inch diameter. In soul mate loss recovery now.

I really admire all you guys' dedication to this! lol

After training with the Square Pegs 3xl Egg Plug (10.4 in circumference/3.3 diameter) for 2 years I finally got the Square Pegs Trainer all the way in. It has a circumference of 11 inches, which is 3.5 inch diameter. It was not easy, but patience, daily training and lube make a difference. https://www.squarepegtoys.com/product/trainer/

I just reached my new largest capacity today. My new Hismuth dildo arrived & I couldn't wait to try it. I really expected it to take me quite a while (numerous sessions) to work up to getting it in. Before today, my largest toy has been only 2.75" diameter. This new dildo is 3.21" at its widest point. I washed it up, connected it to my Hismith machine & lubed it with J-Lube after injecting some lube into myself. Then I positioned myself in front of the dildo & slid little way onto it. I had the machine set for a fairly short stroke because I didn't want it to be too aggressive & tear me. Surprisingly, I seemed to relax & open up quite quickly. It didn't even take me five minutes to have the machine pumping that dildo all the way to it's flange at the bottom. 🤩😍 After a while I adjusted the stroke longer & started trying different positions. By the time I was done, I had that machine pounding me at a good pace! I tried something brand new to me too. I adjusted the machine for full length strokes & stood it up so that the dildo was pointing straight up. I straddled the dildo & lowered enough for it to start entering me, then turned the machine on. Wow, that was the most comfortable way that I tried & I took a great ride that way!

3.21" as deep as it will go! I have a new favorite way to get fucked. 😁

I got some video of the machine doing it's thing on me, but I haven't found a way to add video here. I did add some pictures in my Toys album though.

Princess Spreadums is your medium-phase fantasy plug:

• Insertable length: 4.45 inches

• Width / diameter: 2.25 inches

• Stem width: 1.62 inches

But I’m working on

Queen Petalbloomer (large plug, Phase 3) has these dimensions:

• Insertable length: 6.69 inches

• Diameter (widest): 2.6 inches

• Stem width: 1.93 inches

I did get all the way up to a 3" diameter once, and only once. I was able to do 2.5" on the regular, now I struggle with 2" butt it's getting easier. I'm sure I'll be back where I was in no time. Just takes practice 😉

I got my 3" plug after hours of stretching. Only done it once though.

DIameter: About 8", about the same width as a soda/beer can IIRC

Length: This went technically way past my rectum, but I've put numerous double-dildoes inside me before, the biggest being 3'
