I saw Sawasa13's pic of Asuna in her elf outfit from SAO being tickled, and it only made me wanna make something with her too, as I forgot how cute that elf outfit of hers was, and how vulnerable her tummy was in it~ Small story behind this is simply that Asuna never managed to escape her captor, and so she became his little toy to mess with for days on end... What Asuna didn't realise, was that her character was programmed to be 100x more sensitive than her IRL counterpart, meaning something like tickling was absolutely torturous, especially on her belly and navel, which she was already incredibly ticklish at IRL... It's game over for Asuna, as she spends her days as a tummy tickle toy~
