Oh man, you've no idea how excited I am that this might be filled!! :D To be totally honest I didn't really have high hopes for a response because I thought it might be too "out there"... SO thrilled you're taking on the challenge! This anon isn't too fickle at all about courier appearances or personalities, I love 'em all! And however much shame/embarrassment you would be comfortable with is totally fine, I'm not easily squicked. :P As far as relationships and the like again, I'd be completely ok with wherever the prompt takes you.. although I'd be lying if I said that I didn't prefer some sort of relationship, established or otherwise, to gen~ But either is ok by me!
