Rolling on Roll's Soles [Sketch] (Patreon)

Here is the sketch for an upcoming new drawing! I've been seeing some Megaman feet tickle pieces from other artists and had the need to make some machine tickling to Roll. I couldn't decide a specific design of her so I made my own one based on the most recent version of her (I also made her grow up hehe). 

I'm still thinking about a context for this, I have a couple of ideas so I think that's good for a poll owo
