(Herohero Tom) Debuneko ni Aisarete [Adored by Chubby Catgirls]

This is the English translation. What happens when a boy wants to adopt three very cute little lost kittens? They grow up to be 450 pounds each of SSBBW unruly nymphomaniacs that do whatever they want anywhere in the house! And you thought your litterbox was smelly!!
