My slave also needs regular training so he can be fisted. Here you can see part of his usual training routine. Any volunteers? #rubber #plug #fisting

Bondage bags can be used for flying setups too. Sub can think about what he could do better and master has some time to prepare the next setup. #leather #bondage #estim

Looks like rubber drone was covered in too much rubber and is overheating @folsomeurope.bsky.social 😉😅. Joke aside - it was too much so helped him to remove some of it. But the effect with the modified gas mask connector is really 🔥. #rubber #forcedsmoking #breathcontrol

Could someone give the drone a helping hand, please? The droolhound is making a mess and can't see anything. #drone #rubber #droolhound #cum #slippery

He's a good boy but I think he is missing something in his mouth... maybe that 🍆 could help but a gag will also do the job #rubber #drone #siliconemask @furrjoi.com

Always good to spend some time tightly wrapped in a leather bondage bag, sub can think about what he could do better and master has some time to prepare the next setup. #leather #bondage #estim

There are so many options to use such a good mask. Slave loves to get masters piss directly from the tap 😋🤤 Enjoy to see him struggle and I recommend sound on, especially at the end 😈 #pissplay #piss #yellow #rubber #BC

Slave could enjoy the new silicone mask basic with mouth and eyes, it’s super comfy and you see in other posts how it’s used 🤤 - great work @furrjoi.com

Playtime with Coyote 3 estim box, two sensor set to reaction game. Slave and Sub had sensor in hand and needed to press it when lights turn on. If it’s not pressed in time the other gets shocked till it’s pressed. It happend what I thought… have fun

Estim, rubber and breathcontrol is a great combination - but sub needs more intense treatment

Masterdo77 @masterdo77.bsky.social · 29/06/2026

Massage wand and neon wand combined, neon wand could be more intense but is a good way to start. #chastity #edging #pain

„Bondage starts when you want out“ it says but you need a lot of restraints for that. What’s your favorite restrainment? #bondage #bdsm

Masterdo77 @masterdo77.bsky.social · 22/02/2026

I did another inventory and my slave asked, "Should we have a flea market?" What's wrong with him? You can never have too much of it. What’s your favorite „normal“ restrainment? And what is still missing that I need to get but doesn’t know it yet? 😉 #bondage #bdsm

Slave tried his new cage size, so his large balls are nicely visible and he is also leaking. #chastity #leaking
