After about a week from getting my aneros, I've finally experienced it. I was focusing on the feeling of my muscles gripping and moving the thing around until I reached the point of no return. I found the first orgasm somewhat lackluster but then another one hit me and another until I was moaning and grunting and howling. I started humping the air and my cock felt so sensitive to everything. This went on for about 40 minutes or so. I was soaked in precum by the end of my session.
Honestly, though, what really threw over the edge was letting go and being relaxed. I just went with every feeling. I'm dead silent usually but that feeling will reduce you to an animal and I love it. Worth every penny.
(P.S. Is it normal to still feel tremors after you've finished?)Source: http://www.reddit.com/r/aneros/comments/3evfb0/i_just_had_a_super_o/
