I combined few self bondage scenarios that i found on this site and draw them together just for fun. Feel free to change them how ever you want. Also there is no second backup release method in drawing so you can use what ever you want. You can add additional games in it if you want im probably not gonna draw another one cause this one got out of hands with complexity but its great for fictional use.
All copyright rights belong to their respected owners, this drawing is just for fun.
This scenario is not completed or tested in real world thus for you do it at your own risk!!!
EDIT 1: I just got a new idea for automated deepthroat training session and ill add it in attach so you can check it out. Its pretty interesting but also not tested!
EDIT 2: I added profile picture in description (original version is on boundanna.com gallery but i refresh it a little bit)
PS: if someone want to post this pictures on boundanna gallery feel free to do so i can help you with text part so that can be easier for others to translate.
Also ill update this post every time when i get some new ideas (feel free to put some recommendation or ideas in comment section).
