Gale/F!Tav - Auntie Ethel Needs a Baby (Fuck or Die/Breeding Kink)
This might sound insane, but I'd love to see a fic where things go REALLY awry with rescuing Mayrina and Auntie Ethel still needs a baby or else. So she holds the party hostage, intent on using Tav as her broodmare for the baby she needs. Maybe Tav is involved with Astarion, but since he's dead he can't help procreate, so Gale gets enlisted.
- Tav forcibly bred until Auntie Ethel can confirm it took ++ Tav/Gale do have feelings for each other, they just haven't progressed +++ Astarion is forced to watch the act ++++ Gale is lowkey into the idea of procreating +++++ Your choice if they enjoy it at all or if it's just horrible delicious dub-con/fuck or die
