🤣 I can promise that this was a cleaning toothbrush that I bought specifically for cage cleaning 🤣

Rule number 1: there are no rules except those you mutually agree to! And rule 2: no chaffing, lots of lube! 😂 Enjoy!

This is supposed to be fun, challenging yourself in a new way, and hopefully feeling sexy while doing it. You come first.

Nathan Grefseng @grefsengboy.bsky.social · 01/10/2026
You can still be dominant and want to lock up. You can use this to focus or build connection or just be slutty.

Nathan Grefseng @grefsengboy.bsky.social · 01/10/2026
You are still a good sub if you have to take it off for work or to sleep. You are still a good sub, even if you can't cage at all or don't own one yet. Remember, this is all about fun and pushing yourself.

Nathan Grefseng @grefsengboy.bsky.social · 01/10/2026
You are still a good sub, even if you don't have a chastity cage. You are still a good sub whether you make it 1 day or go all the way through November. You are still a good sub, even if you don't have someone holding your keys.

Nathan Grefseng @grefsengboy.bsky.social · 01/10/2026
Lots of lube to use your cage, listen to your body, and take care of yourself! This month can feel like a gauntlet so take the necessary steps

It's officially Locktober! Some reminders for everyone as we begin. Whether you are participating or wish or were
