Due to reasons, I had to unlock 110 days into my 329-day chastity challenge back in April. As of 5 Aug, I am locking up again but only during my waking hours. I promised you all to stay locked every hour you gave me, so at the current pace, it seems I will be doing this until August next year 🤣 🔐

Where do I sign up for your version of pride? 🥺

Q (from NGL): Have you lost any continence wearing nappies? A: I wear pullups 24/7 but still mainly use the loo, so I haven't had a chance of any actual incontinence. I know it's wrong to wish for it, but needing to wear proper nappies all the time would sure be a nice permission to do so 🥺

Q (from NGL): Do you 1 or 2 or both in your diaper? Chances are I'm doing one or the other in this pic! 🙈 I don't mess very often. As nice as it feels while doing it, the clean-up is just disgusting. Unless I'm bullied into it... In terms of peeing, I am a firm believer in maxing out my diapers!

Q (from NGL): What got you into diapers? A: My other kinks have always been there, but this is relatively new. I think it's a humiliation thing for me. It's the ultimate embarrassment. But once I started, I realised how comfy it is too! I love the weight of a well-filled diaper between my legs! 😅

Just having a lazy Wednesday evening 😊

It's been a while since I posted here. I had a bit of a health scare which could have been serious, but seems to have worked out fine. I'm definitely having kinky thoughts again, so I will be posting soon, once I unpack my boxes of gear (I've moved house as well). An old pic in the meantime

For me, the laziest kink night possible is to just put on a diaper. In fact, it's easier than not doing anything at all 😅

I, for one, don't mind April showers 💦

I'm too lazy for rubber tonight but I found this pic in my library.

In cases where no padded cell is available, padding may be applied directly to the inmate instead. (Tbh, I wish I could have both 🥺)

Q: In a prison, would you prefer having your own cell or sharing with a cellmate? Sharing a cell is a great way to get to know someone, and it definitely makes time pass more quickly. But my big craving is for solitary confinement. I want it to be tough. It's not prison until I want to get out.

🗓️ Chastity Pig's log, day 31: I've reached the point where it feels totally natural to be locked. It's just how it is. But it's also a source of happiness every day. No matter what else the day brings, I'm constantly engaged in something that feels true to who I am. Bring on the next 9 months!

It seems every Wednesday night is turning into a diaper night these days 🐽 It's nice to get an upgrade from my 24/7 pull-ups, but for some reason I can't bring my legs any closer together than this at the moment...

Actually, I should post an up-to-date cage check, since I've started week 3 of my challenge! 🔒 Day 21/302 ... or day 48 since locking up Btw, if you're unimpressed by the lazy mirror selfie, I'm becoming increasingly susceptible to suggestions for how to do the next check... Just saying 🤷🏻‍♂️

MattySub @mattysub.bsky.social · 22/02/2026
Here's one from the other week. I know a collar is just a necklace when one has the key, but would it count if I put it in the lockbox that's holding the key for my cage? 🤔

MattySub @mattysub.bsky.social · 12/02/2026
🔒 Cage check on day 10/302 of my sentence ... or day 38 since I locked up I'm doing quite well so far, if I may say so myself, and I think a bit of bullying in the comments is deserved 🙇🏻‍♂️

Doing your finances doesn't have to be boring 🤓 Pro tip: Add 3 boosters and you can keep going until you're done 👍🏻

MattySub @mattysub.bsky.social · 01/02/2026
After all that, I think it's fair with a cage check. Day 1/302 of my challenge 😳 (and it's day 27 since I locked up)

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. (5/5)
Line chart counting up total number of days each day of the challenge: 45.5, 113, 179.25, 208.25, 248.25, 301.5 days

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! 😬 💛 Like = 12h 💬 Comment = 6h 🔄 Repost = 24h Deadline: Sunday at 12:00 UTC

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

MattySub @mattysub.bsky.social · 22/01/2026
It felt great to be back in rubber and restraints last night. It's been far too long since the last time!

MattySub @mattysub.bsky.social · 21/01/2026
I'm just having a quiet night in tonight. Since the keys are locked away in the lockbox for a couple of hours, I'm pretty sure it will stay that way... 😈

MattySub @mattysub.bsky.social · 17/01/2026
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.

MattySub @mattysub.bsky.social · 10/01/2026
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.

I can’t argue with that. Four hours later… 🫣

MattySub @mattysub.bsky.social · 09/01/2026
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… 😝 Day 5/?

MattySub @mattysub.bsky.social · 14/12/2025
Day 29 cage check 🔒 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 😰

MattySub @mattysub.bsky.social · 10/12/2025
Having a quiet night in. Still locked and constantly in pull-ups. It's been 23 days so far.

MattySub @mattysub.bsky.social · 10/12/2025
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 🫣

Q: Is orange the new black? A: As an inmate, I wouldn't have any say on what colour my uniform is anyway 😛

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! 🤩

MattySub @mattysub.bsky.social · 27/11/2025
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?

MattySub @mattysub.bsky.social · 25/11/2025
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.

MattySub @mattysub.bsky.social · 24/11/2025
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! 😋

MattySub @mattysub.bsky.social · 24/11/2025
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! 🔒

MattySub @mattysub.bsky.social · 24/11/2025
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.

Which toilet do you choose - left or right?

Question (via NGL): Hi Matty! What is your favourite chastity device? A: My Behind Barz 🥰 It's so secure. Solid. No way out. And it's surprisingly comfortable. Sadly, it does start chafing after a couple of days. The Cobra is the more realistic option for when I get back to being locked long-term.

Anyone else excited for puffer season? 😝

If I were only allowed one piece of rubber, I would choose my diaper suit. Amazing design, feels great to wear and exposes my diaps and stops them from leaking. What more could anyone want? 🖤💦 What piece of rubber would you choose? (suit from @regulation.store)
