Maia the Mermaid GTS Page 26 (Patreon)

Just this one human, and then I'm done, I swear!

I'm half joking, I think Maia just wants to taste the human, not eat him. As long as nobody gets hurt this should be absolutely fine. The inside of her mouth is  nice, soft and warm, and the human doesn't have to keep swimming and exhausing himself to keep his head above water, it's a win-win.
