How about Aiko eating or cooking herself?

for example
Aiko is standing near to the stove or plain table where one of her breasts is being cooked in the frying pan while Aiko is holding fork and knife in her hands.
Also the breast which is still on her body is skewered with long carving knife.

Or alternatively simpler version to draw, romantic proposal:
Aiko is offering plate with her severed breast while her another breast is skevered with burning candle. Of course she is in good mood and smiling.
