Five nights in Anime

This is a hentai parody of the FNAF franchise, but it's lore has some differences [I.E: names] from the canon franchise, and will only focus on FNIA versions of the first, third, fourth and security breach games.
anyways plot:
Ian is the young son of Wendy Afton, the owner of the Freddy Fazbear anime convention with her friend Hayes Emily. while a friendly place for children, at night the animatronics soon unveil a secret of pure lust... they only want to 'play' at night...
Ian's best friends, and eventually even he, eventually end up entangled in his mother's own business, on one tragic night that happened to his mother...
and so begins a saga that spans across what seems as four parts....
and a future of a mega animeplex... or anime pizzaplex? idk.

[although there will be lemons, the appearance of the animatronics won't be as NSFW coded as the original fangame, but will still be gooner material]
