Tattoo progress today! As expected, numbing cream does nothing at all on the back of one's head 😅
I'm so, so happy with how this looks - can't wait for the swelling to go down and for it to stop hurting!
A bit of shading to blend into the existing hexes to go.

It's important to make sure their rubber lined holes are actually properly rubber lined.

Absolutely speechless - @home4boys.bsky.social has only gone and included one of my pumps in their latest tattoo (and very nice it is too). Wow!

First outing of my new muzzle from @kbboy.bsky.social - it's so wonderfully restrictive.
Next up, attaching a funnel for some urinal play 😈
Thanks to @kinkybiologist.bsky.social for the pics :D

It's so pleasant to just relax and let the machines take over. No thoughts, no worries, just the warm, insistent embrace of rubber and the machines deciding when you can breathe 🥵
Thanks @kinkybiologist.bsky.social for making sure the conditioning went smoothly!

Something delightful just arrived from @kbboy.bsky.social - outstanding quality and service as usual. Fits beautifully ^_^
Suppose I'd better give it a thorough test now... anyone feeling well hydrated?

From earlier in the week: Mandatory hotel room mirror pic before I got my hole absolutely destroyed by a lovely gentleman ^_^

I've got to go up to Liverpool with work next week, so will be very bored on Tuesday (2nd December) evening.
Anyone want to do rubber/bum/throat destruction things with me?
Pic for attention 😅

Part two of my training from the other day. Absolutely cunting myself with my favourite toy - my @hankeystoys.bsky.social Dragon XL, being relentlessly forced inside by my @cyborgtop.bsky.social machine.
The state of my hole at the end is just 👌

One of my favourite toys - @twistedbeast.bsky.social Bael (large, I think?), being forced into my insides by my delightful @cyborgtop.bsky.social machine.
Deep (for me anyway!), slow, short thrusts with this thing feels so good 😈

A thing happened this evening - I finally actually set up a camera and filmed myself again! Can you imagine!
Suppose I should edit this and post a few bits, that is if you don't mind silly involuntary bottom noises?

After getting absolutely ruined by @sethmun69.bsky.social last night, it seems my hole just wasn't finished.
This was 10 minutes after finishing work today. No warmup, just straight onto that nice big ridged alien monstrosity for an hour or so
No, I've not got a problem. You've got a problem! 😅

So happy I've lost enough weight to get into my 1mm straitjacket suit again!
Thanks @sethmun69.bsky.social for absolutely rearranging my insides and ignoring my attempts at resisting the other day 😈
