The Warrior of Light (F!Raen or Hyur, probably) has always had an affinity for the Namazu of their homeland, even if it’s tempered by a sort of fond exasperation at their antics. The Namazu, for their part, greatly appreciate the Warrior’s said in other matters, but require just one more thing of her before she leaves for Eorzea once more…

OP wants the WOL to get (mostly consensually but incredibly unsatisfyingly and embarrassingly) gangbanged by dumbass fish people, anons. I don’t need it to be sexy, I need it to be fucking ridiculous. I need this for reasons.

Male WOL is gay. Lyse is a lesbian. They’re both grieving Papalymo, at least a little drunk, and decide to shag. It is the absolute worst sex either of them has had in their lives.

Feel free to write the terrible sex, the aftermath, or both! I would prefer the story ends with them still friends and (eventually) able to laugh about it, but so long as the bad idea is mutual (no noncon/dubcon), go where your muse takes you!
