Fell in love with my inflatable plug
I recently got into self-bondage (fun with 3D printed ice locks) of course with something inserted in my backdoor.
I thought something electrical like a vibrating thing or a pulsating plug would be the most fun, but I was wrong. While my hands were tied behind my back and only being able to make my plug inflate squeeze by squeeze, I noticed how sensational it is to just move my hips like I would ride something while tensing the Kegel muscle. It felt like I was getting penetrated by something big without the pain of too much friction.
I did it for like 30 minutes, and because of the bondage part, I was really able to focus on the feeling. After a while, I felt that I needed to pee (the one I always read about). A little while later, I actually came hands-free for the first time. It felt phenomenal, and I want to do it again soon.
