An amish dildo. Made out of natural materials that would be made out of things that the amish can use. (i.e. no modern materials: plastic, gellatin, any electricity, or other things.) A flim can be carved wood, yarn, sheep bone with(out) wool on outside, foot, or any other thing like that.
Robert took it hardcore up the ass with a flirm made of splintery wood. He liked it.
