I'd recommend anything "soft" i.e ice cream, or anything that doesn't run risk of falling off. Also, don't forget: the vagina! what you could do is shove a cucumber into the girl's pussy, really deep into it I mean, and then just leave it there for a few days. Then, later take it out and eat it like that; by that time,it will have turned into a pickle! It's what I call, "deep pickling".
