Hands free dick vibrator?

So for context my gf pegs me, and i love having my hands held behind my back while she does it, which makes stroking a challenge obviously lol. Also have been really loving the idea of cumming hands free, kind of an “out of my control” type of thing.
I’m wanting to find some sort of hands free vibrator that attached to my dick. Something that really gives that sort of “edging” feeling. Preferably something that also targets vibrating around the head and extra sensitive areas of my dick. Anyone have any thoughts?
