Finally gave this thing a few more tries. WOW. I surely opened the ring up too wide, it has been edging me for long periods of time. Two nights ago I intended to cum in it. But its so open and soft and the stroking inside the toy was good but a little weak. So for guys with larger than 5.3-5.5" girth, you're going to fit perfectly I think. It edged me for about 20 minutes, I was in it the whole time, lube was good I never applied more. I had to fuck the sleeve while the stroking pattern was going, which felt pretty crazy, and then stopped just before PONR to let it stroke me to orgasm. Fuck it was a long big one, it can do things my hand and brain can't connect to do. If you put it on the Masterstroke patterns, or the AI pattern, you'll get close and then back off, close then back off and you can't control it unless you change pattern or pull out of it. It doesn't weigh too much so I can hold it against myself while on my knees just fine. Or lay it on a mattress on the floor and lean into it. Laying down its good too, your pelvic bone and sides next to your cock take the weight of it and you just need a hand to leverage it to stay upright. Moving it around different angles makes the ring put more pressure and stimulation on different sides of your cock, which is fun for edging even more. As mentioned, my orgasm was very full and large deep inside the machine.
Last night I did a prostate session and when I was ready to cum brains I used the toy on my cock instead of my go to Fleshlight; on my back I pound it with an Aneros in me for a Super T and insane draining cum. The Autoblow got me pretty close, it edged me very good, and made me have several dry Os while being hard inside the toy, it felt fucking wild! I didn't want to wait for it to finish me off so I went for it with the F'light, and shot all over my chest.
Next time I use it I'll tighten the ring a little bit more for a slightly tighter grip. It needs more pressure, if its too light you'll just edge if you're used to the feeling like I am now. But its fun to have the option to loosen the inner ring so you can edge for a long time.
If you are 8" bone pressed you'll fit inside this thing. I'm 7.7" or so bone pressed and I jam the toy as far down on me as possible I have a minor fat pad, and I'm all the way inside it. Never has an automated toy taken my whole cock. This thing has depth! I think its worth it. I got it for $200 on the "daily special" they run which is every single day of the week.
