SCP-4913

so i don't know how to wright one of these stories but i have an idea for a scp. it is just a ordinary ballpoint pen but when people hold it their minds get flooded with great ideas but as they try to sketch the idea down the ink sinks into your hand and well, you know the scene from AKIRA where tetsuo explodes. pretty much their hand/arm just turns into a blobby flesh sack and is useless until the pen decides its done and falls off. the arm falls off with it but when it falls off the arm just seals into a stump so there is no bleeding. it is just really painful. tell me if this is a good idea because i don't know ya know.
