After all that, I think it's fair with a cage check.

Lastly, if anyone is a nerd like me and curious about the numbers, here’s a chart from my tracking sheet.
I realised quite early on that I was screwed!
I sometimes say I have a fetish for spreadsheets, but this is the first one to actually give me a boner 😂
End of my acceptance speech.

Just having a chill evening at home 💁🏻♂️
That chastity challenge is not taking it easy, though... The current figures suggest I will be locked until at least 7 June, and there are still 4 days to go 😳

It feels good to be back in chastity, so let's do a #chastitychallenge!
After all, measurable goals and accountability are how to get things done!
Let's see how long I'll stay locked for! 😬

Will I regret using my cleaning break to change into the belt?
Possibly, but not a whole lot I can do about it now 🤣

It felt great to be back in rubber and restraints last night. It's been far too long since the last time!

Since the keys are locked away in the lockbox for a couple of hours, I'm pretty sure it will stay that way... 😈

I'm trying out a size S cage instead of my N+ for a few days to see if it helps me wake up less often.
It hasn't really helped, though. And I don't really manage to fill it during daytime 🤣
I think I will need to revert to my normal one.

I'm craving getting properly locked up again but am reluctant to go to the US at the moment 😢
Anywhere in Europe where I can get a realistic jail experience? The place I've heard of has somewhat mixed reviews.

With the holiday behind me, I’m back to being locked until further notice.
Today, I’m in proper diapers instead of pull-ups so here’s a quick cage and diaper check 🫣
I could get used to this… 😝

I've got just five more days to go now, but with the end in sight, I suddenly don't entirely oppose the idea of getting bullied into remaining locked until further notice 😰

Having a quiet night in. Still locked and constantly in pull-ups.

Q: What's the longest you have been in diapers?
A: Oh, I don't know, actually. In proper diapers, not very long. Just a few days at a time. I do fantasise about going 247, though 🫣

A quick cage check, 3 weeks in
I’m honestly living a better version of my life when I’m locked 😇
Almost a shame I will need to be unlocked in two weeks’ time for my xmas and new year’s travel.

I love those kink jars and whatever people use to show their kinks, so I decided to take it one step further and get a custom illustration from the talented @spacepupsilver.com to show mine.
I’m super happy how it turned out! 🤩

I dribble a bit when I’m locked, so I’ve accepted that being locked also means wearing pull-ups 24/7. It’s been 11 days so far and it’s already feeling completely normal.
Btw, any recommendations for which are the best ones?

Q (via NGL): Can we see face pics of you in your jail scrubs?
A: I used to post my face. I enjoyed the risk, and if people found me, it'd be because they were looking at kink themselves, so no big deal.
However, AI and face recognition have changed the odds too much, so no more face pics for me.

Question (via NGL): Do you do something specific to prepare for drinking a lot of piss?
A: Lol, I’ve never thought of any special prep ever being needed! 🤔
I think I may need to drink more to find out! 😋

I haven’t been locked nearly as much as I should have this year, only a few days here and there. I just haven’t been feeling it 😢
That’s finally changing, though! I’m 8 days into a stint that won’t end until the xmas break at the earliest.
Feels good to be back where I belong at last! 🔒

Question (via NGL): Are you looking to meet others for a gunging?
A: That would have been a lot of fun! However, I don't play apart from my husband, so no. Not unless we relax that at some point.
I am seriously considering going on one of those gunge experiences, though, like Goop Quest or Splat.
