I have an idea. Ever have Dangos? I have eaten them and thought to myself the rice cake reminds me of skin. Put rice cake over top of chicken somehow and use some roleplay and imagination? You can use meat from the store and pretend, and it could be pretty arousing/fulfilling. maybe get some gorey prosthetics/makeup after halloween when it all goes on sale, and incorporate that. Maybe fill a prosthetic wound with some rice covered chicken so its like biting a peice off
