Unfortunate Update:

Gumroad, the storefront host for all of our audiobooks, has just updated it's TOS so that it no longer accepts NSFW content. This includes most of our stories, and we will very likely have downtime where stories are unavailable to purchase. We will be working to find an alternative host for these stories.

Our apologies for the inconvenience in the meantime.

Her chef bots are selling well, though you doubt anyone else has three actively cooking at all times to keep them fed. Let alone developing a weight gain pill on top of that.
