Oh, all the inanimate things I've forced myself on in my days. The list of fruits and vegetables is long and varied; bananas, pears, eggplants, melons you name it. If I ate half as much fruit as I fucked I'd be quite healthy. Well at least physically, lol. ...Various pasta(in cans), pasteries, I actually tried fucking dough once, I made it myself for the purpose of experiment. Huge failure.
Balloons, condoms/bubble-warps, clay, the list goes on. About the only thing I haven't fucked is an actual woman.
