@Cookie For now I just use mine as a standard stroker. I tease the front mouth/tongue part at first to warm up and heighten the realism then go to town on the Deep throating. In reality a real woman would never be able to DT me for as long as I use the onahole without several breaks so I'm getting a somewhat unrealistic BJ there but it feels so damn good. I have considered what it would be like to use it hands free in my meiki plush torso but I think the teeth would ruin it/throw me off. Maybe without the teeth... hm. But it would still be weird. I have also considered make-shifting one of my spare wig-heads (made from styrofoam), carve out the mouth area to be insertable for the onahole, Set it up an a nightstand or couch arm, plop a female wig on it and use it hands free that way as though I'm face fucking a girl. But... a lot of work for minimal payoff to me. I can see the appeal of what Bond Pony writes below. Never thought of using one of those motorized sec toys but that would do the trick to really capture the feeling of a girl having control and doing her thing to you with her mouth while you just sit/stand there.

I shove my oral sleeve into electric powered sex toys. You can adjust the speed settings slow to fast. The thrusting motion only moves about 3 inches up and down but it beats using your hands to hold the sleeve. There are a bunch on amazon around $50-80. I own 3 and got them all for free. Many of the chinese companies give them away for free in return for 5 star reviews with photos.
