Ok folks. Strap on harness recommendations. Ideally based on use/experience.

I'm not going to be doing Locktober this year, mainly because of some recent irritation that means I'm going to be quite gentle with my PA for a bit. I'm not going to cum during October (of course!), but I'm wondering if anyone has ideas for alternative Locktober activities.

I hadn't been for a plugged run for a while, so when I felt like it this afternoon I made sure to choose an easy and comfy plug. I realised my mistake about 4k from home when it became clear I was getting progressively more relaxed and it wasn't going to stay in! 😬

I like the fact that my work has done a subtle "fuck you" to anti-trans guidance by now having a basket of tampons and pads in all toilets in the building rather than just the female and gender neutral ones.

And here's another view of the marks that @selonswitch.bsky.social switch gave me during my first night at @quaelgeist.bsky.social this year 😁
A man is kneeling on a bed in a hotel with his arms up above his head. There are two large purple splodges covering most of his butt cheeks, a sign of a good night!

@selonswitch.bsky.social certainly knows how to leave an impact! 🥰 I keep getting compliments on the marks (and they've been refreshed since this photo as well) 😁

After a bit of a delay thanks to Tuesday's travel shenanigans, I'm successfully in Berlin and comfortably settled in. I've got a few little plans lined up (catching up with friends 😏, trips to Quälgeist) but do get in touch if you're here and you think we'd get on 😁

I'm not really locking all that often while I wait to size up my PA, but tradition is tradition

Well, I should have been on my way to Berlin now, but the UK flight disruptions mean an extra 24 hours in Bristol. On the plus side, packing tomorrow will be straight forward!

It was kinda fun to do the US dialect quiz as someone who's never lived there. I was excited to see that "bubbler" exists outside Australia, but disappointed that neither "slater" (my term) nor "chucky pig" (my favourite SW English term) were offered as options for woodlouse.

Q for chastity peeps with PAs! I've been unlocked for the last little while while I let my PA heal and size up but I'm also really missing being locked. I've tried locking over the top of my PA (CBR, now 10g=2.4mm pierced at 12g) and it's just not comfy, especially for sleeping. (1/2)

Brutalising or tenderising? Either way, I certainly had fun 😁 Hopefully there will be opportunities for more beatings when I'm in Berlin next week! 👉👈

Just chatting to a friend about formative kink memories and it led me to reopen a book of Norse mythology that was a bit of a sexual awakening for me when I was a kid. Main highlight would be this illustration by Giovanni Caselli of Loki being punished after the death of Baldr.

This is the pre-Folsom Berlin crowd's reminder to order your home STI tests now, so you have ample time for return, any treatment and/or retests needed ahead of QueerSoupWeekend™️in a month

For anybody who follows me who engages in pup play, a journalist reached out and wants to interview a pup for their book exploring different aspects of pets (including pet play). Anyone interested, feel free to message me and I can pass on details :)

I'm starting to get distracted thinking about Folsom Europe - just over a month until I'm in Berlin again! Looking forward to reconnecting with people and making new friends 😏😁

A random musing: one of the things I really enjoy about kink is exploring what makes us both tick, with so many different kinds of human.

as the weather heats up, your friendly neighbourhood slut is here to remind you: - models/fitness influencers are literally paid to look like that - you can do someone else’s workout, eat their diet, ape them entirely, and your body will still look different - eat more ass 💅😌🍇☀️🍷

I sometimes fantasise about being sent to an isolated outdoor location where I strip, cuff myself, and wait, contemplating my situation before a dom comes to abuse me. I don't think it's something that I'd ever really do, but it's nice to have the time and space to imagine what it would feel like 🥵

I cycled past a cute guy earlier. He was giving off "indie rock" straight guy vibes - vintage clothes, cool demeanor etc. But he also had a massive red bandana hanging out of his right pocket and it made me wonder if he wanted to get fisted 🤔

Drooling and struggling in an arduous bondage position until I tortured him to a hands free orgasm, @asympmaso.bsky.social found the bondage didn’t stop after he came. Neither did the Deep Heat on his balls or the harsh clamps on his tits. But I did add the TENS machine to torture his ab muscles…
