„Bondage starts when you want out“ it says but you need a lot of restraints for that. What’s your favorite „normal“ restrainment? And what is still missing that I need to get but doesn’t know it yet? 😉 #bondage #bdsm GimpAlex

Video 1 - Slave and GimpAlex could test the new pump plug machine. While one plug is filled the other was deflated and vice versa. Next adjustment is reduced loudness and more air in plugs. Enjoy. #cbt #plug #dildo #anal #rubber #slave #sub

First test round, slave said feels like being fucked and it’s a lot of fun 😈😂. Setup: instead of milking cylinder it’s a pump plug with hard core inflated and directly deflated.

Squeaky little rubber slave loves his ass being used 😎. The gloves are really nice and every finger has a different shape - sound on - these are the sounds of orgasm through anal stimulation.
