Like really badly too! I don't know why, but slime hentai is best hentai to me always and I just really like some of the things they seems to be able to do, like changing shape and becoming as solid or liquid as I like.
And I'd feed off jello to gain biomass and my core or whatever it is that becomes my brain/heart will be able to move around in my body. I'd be immune to bullets, mostly, and can regenerate myself too!
And I think it would help out in bed as well ;) being able to stick slimy stuff up there and make my own vagaina into various textures that feel better... Free lube too, as I'd be made if the stuff basically
So if you had the choice, what kind of monster-person or creature would you become? I dunno why but I'm hoping one of you picks "gargoyles" because I dunno.
