Nyara-nyara... (Patreon)

A guy is dared by his friends to check out a mysterious newly-opened shop, rumors saying that it has a magical elixir that promises anyone to drink it to "get into a hot girl's pants." The shopkeep looks over the new customer with a knowing eye, and sells him a set of those elixirs. When the guys drink their potions, the transformation occurs; but it turns out that our hero is really into mature women - and catgirls!

The newly transformed feliform woman finds out that not only is she a curvaceous catgirl in her late thirties, but her friends have now become her adult daughters!  Looks like mama kitty has a lot of work ahead of her; at least she gets a family discount on future purchases!
