With how busy life has been lately, I’ve had no choice but to ignore him for weeks at a time. Haven’t been doing any trimming or upkeep either. He’s becoming quite neglected looking.

New jock style chastity restraint. This oughta keep the cage more firmly centered instead of pulling it upward.

Evening cage check! Anyone know of methods to empty a prostate without triggering an ejaculation or stimulating it anally? I’m on a no-orgasm diet so I’m trying to find new ways to drain its fluids; my system is six days pent so I’d like to get it emptied soon.

Tight thongs support cages perfectly.

Good morning! Another day, another cage check. Do you think I’ve earned a break from the cage today? Repost if you think I should take it off, or Like if you think it should stay on longer! I wonder what will happen…

Phew, safely locked again. Feels much safer when it’s covered in hard plastic.

It got let out briefly for some monitored edging! I’m lucky that there are wiser males out there who can administer controlled doses of edging to the penis so that I don’t get carried away and accidentally make it spray sperm all over the place.

Five days pent! I usually would’ve still been in bed edging for another two hours, but with a cage getting in the way of self pleasure, I’ve already had breakfast and showered. I can actually focus!

Yeah, my libido is way too worked up for me to be trusted with my cock out. Way safer to keep it in its cage so I can’t waste time and energy masturbating or ejaculating.

When I was a teen, it was way smaller and actually felt like it was a natural part of me. But as I've grown older and it has grown disproportionally larger, gotten way veinier, and turned red and raw, it has stopped feeling like it's mine and started feeling alien and unnatural.

Hot take: Bacterial cultures that thrive in untreated sweat are NOT musk. If you like that sour milk smell, it's not musk that you're into; it's bad hygiene. Real musk is what happens when the bacteria can't run rampant and your pits build up natural odors that aren't overrun with locker room funk.

Self pleasure makes me weak. Real pleasure is derived from servitude and compliance. Pursuing one’s own urges is selfish and demonstrates a lack of honor. 🔒

I feel different. Must be post-freedom clarity. 🔐

There’s something about flexing while wearing a cage that makes me feel even more masculine than I do without one. I feel more complete somehow.

Luka Buck @lukabuck.bsky.social · 07/07/2026
He’s a bit cramped in there, but this beats losing my entire morning to edging. The increased mental clarity that comes with caging is definitely a perk!

Good morning ^^

Phew~ I made it back home without uncaging! Time for a celebratory shower :3

Morning cage check! I’m starting to wonder if this is going to become a long term thing…

Road trip cage check!

Cage check for my last day at the con! I successfully failed to have sex or ejaculate the entire con. It feels a bit disappointing, but I’ve been told by multiple wiser males that this is healthier for me in the long run.

He kept getting fully rigid in my shorts so I had no choice but to cage up. Maybe I can let him back out after he’s stopped trying to flex so damn much. Or do you think the cage should stay on for the rest of the convention?

Bone was absolutely throbbing in my shorts earlier. Had to duck into a bathroom to let it breathe and pulse out in the open for a bit until it calmed down.

Do you like my shorts? They’re a little revealing, but I’ve been instructed to avoid underwear during the summer.

Eager buck penis is at AnthroCon! I wonder if my erection will get bullied by anyone… >w>

Look how red and raw it looks. Can’t believe I was entrusted with such a rigid babymaker- it just makes me feel overwhelmed and dumb as fuck. I don’t have a single top-urge in my subby buck brain. I’m squandering the hell out of this length.

Luka Buck @lukabuck.bsky.social · 28/06/2026
Do you ever feel overwhelmed by it? Like it’s too much?

Had a dream that for pride month I came out as asexual, but one of my followers didn’t approve of my continued sexual bond with my own male sex, so he used hypnosis to help extend my asexuality to my penis so that I’d stop masturbating it and become fully ace.

Just got back from a bike ride. My junk is hot, sweaty, and pent up. No time to give it attention though, I’ve got too much to do around the house!

It has no idea where to go. It’s totally trapped. I hope it gives up soon cause my balls are getting absolutely yanked.

Luka Buck @lukabuck.bsky.social · 20/06/2026
I used the long cage to get my erection contained, and then switched to my smallest cage after the rigidity decreased.

Luka Buck @lukabuck.bsky.social · 20/06/2026
Lapsed and forgot to cage before bed. Woke up unreasonably hard. When I’m pent like this, the only way I can stay asleep is if I’m locked. Nocturnal erections will keep me up for hours otherwise. Wish me luck falling back asleep.

Got some chores to do and it’s a little chilly out, so I’ve got sweatpants on today instead of my usual shorts. My junk looks heavy in that jock.

When he wakes you up in the middle of the night and demands to have his photo taken.

The weather is so nice I figured I should get some weight on my nuts to help them hang lower.

Some recent pics of my donkey shaft. It’s been more active lately because of the summer heat.

It would appear that this poor doberman had his underwear confiscated! Hopefully he calms down before he abstracts~ 👁️ YCH commission for @fahlmavitane.bsky.social 👟🩲

The number of dreams I’ve had where pants and underwear are entirely optional lmao. Sipping on a smoothie and walking through the mall and literally no one cares. Shirts and jackets are still cool, but everyone’s bits are out and nobody cares cause society is just used to it. ¯\_(ツ)_/¯

Got new undies for Christmas! They hold my cage and boy balls perfectly. If you didn’t know; grey happens to be my favorite color~ uwu

What do you think? Do I look better locked up?

This singlet feels so hot. Looks great with my cage on underneath too. Do you think anyone would notice if I showed up to wrestle like this?

Woof. That’s a tight fit. Almost didn’t get it inside.

Check out this new singlet @bair.slut.dog got me for Christmas! Hmm… should I point it up, down, or sideways? And who’s gonna wrestle me first!
