Pet Me Once

After constantly being told that he'd die alone with just a cat to mourn him, Natsu wasn't exactly surprised when his friends left one on his doorstep as a stupid joke. It's only when the cat suddenly transformed into a really hot, busty blonde who couldn't seem to understand the concept of personal space that Natsu had to do a double-take. "Nyaatsu, pet me once" God help him! [AU]
