If I was a macro vixen, I would avoid the sky of course. Birds and bugs, yeah, I wouldn't want that up my nose. Also, flowers, of course, although my fursona does not have allergies. However, for the other question, I would love to step in side a male macro fox or wolf's nose. I would love crawling through the chambers; gently swishing my tail and long hair against the squishy, soft walls. I would put my hands on the walls and feel the vibrating tickle through his poor nose. I would crawl to the most sensitive spot, not giving him any mercy. Uhh...enough of that.
So ya, basically I would rather not be the macro, I would like to make the macros sneeze.
