Big Bro is, as the kids say, “down bad,” and I think he should get bred. I think he would love it. I think he would be reserved and SUPER embarrassed about how much he wants it while it happens but by now he’s had character development so he can’t pretend not to anymore, especially to his beloved Lamaty’i.

Okay so Honey B. Lovely’s power is basically sex pollen, right? Let’s get on this. Two combatants go up against her at once and wind up fucking in the arena while she and the announcer offering teasing, lewd commentary and the crowd cheers for more.

…And while totally optional, incest fans could have the combatants be a Black Cat/Wicked Thunder pair. :3

Spoilers up to the end of the first half of DT

beware of spoilers! Level 92

Kuzuku is fed up with how much time his little brother has been wasting with the old chef after he warned him not to and decides to fuck out his frustrations with the man over it.

Weird Au’Ra dicks welcome and encouraged and bonus if Esugen gets one of his breathing episodes during the fuckery and Kuzuku doesn’t stop

Emmanellian is a known flirt, but not a particularly successful one. Haurchefant is incredibly popular with both men and women. When they’re both younger and Haurchefant is staying in his father’s home, Emmanellain is trying to woo some pretty thing, but Haurchefant manages to charm them first. Emmanellain discovers them in some corner of the estate, and knows he shouldn’t be watching, but can’t seem to tear his eyes away.

An alternate take on that part of Stormblood where Asahi attempts to draw out “Tsuyu’s” traumatic memories where things get taken to more of an extreme.

Before they left Sharlayan with their grandfather, Alphinaud was definitely a mama’s boy. Whenever he’s having a stressful time, or being ‘bullied’ by his sister or the other kids at the Studium, he comes to his mother for comfort.

[…]

Bitching is when a character who was previously an alpha (or sometimes a beta) becomes an omega, either because there are too many alphas in the area, or because they’ve been regularly submitting to another alpha (sexually or non-sexually), or they’ve ingested or been exposed to enough of another alpha’s pheromones or bodily fluids that their biology starts to change around it. There’s a lot of variation and the mechanism that triggers the bitching can really be anything you want.

In order to satisfy the elementals, the padjal must make ritual offerings of life-giving aether… or something like that. The excuse you come up with to facilitate it is up to you, OP doesn’t care much as long as the seedseer siblings fuck in weird, ritualistic ways. Bonus points if the incest isn’t normalised and both older sisters are initially uncomfortable with the idea of taking dick from their little brother. Maybe a now deceased padjal like A-Towa-Cant used to fill A-Ruhn’s place in the ritual?

TLDR, Kan-E and Raya fuck the shota.

Erichthonios, pre-Pandaemonium, dreams about a version of his mother that does not exist. He dreams of being held tenderly, of being praised and loved and valued by at least one of his parents, but eventually, his dreams take on a more lurid aspect. Basically: Eric dreams about breastfeeding from Athena while she jerks him off.

Alphinaud and Alisaie are in an incestuous relationship, but not necessarily an exclusive one. Alphinaud’s crush on Estinien is embarrassingly obvious. Alisaie teases him about it, but she’s a bit curious despite herself, and makes Alphinaud tell her all about this handsome, rugged dragoon and every single sordid fantasy Alphinaud has about him while they’re fucking, but ends up getting surprisingly into it herself and starts thinking about bringing him in as a third.

Bonus points if Estinien treats Alphinaud like a younger brother more than anything, but, given the whole incest angle, that just gets the twins off more.

AU where Athena decides Erich is a failed experiment, so, using whatever means the writer prefers, she restrains Erichthonios and non-cons him into impregnating her a second time (since obviously Lahabrea isn’t up to the task)

Bonus points for Erich being absolutely terrified by the idea that it might work and trying to hold back his orgasm for as long as possible but Athena forcing it out of of him anyway.

Erichthonios is attracted to Themis but projects a bit of his mommy issues with (and fucked up attraction to) Athena onto him. Lahabrea fucks Themis in front of him to try and break him out of the mindset, but is also obsessing over Athena so he’s WAY too into fucking her proxy. Erichthonios feels guilty and aroused and isn’t sure if he’s more jealous of Lahabrea fucking Themis or Themis getting fucked by Lahabrea. Athena may or may not be actually present, but she’s important enough to be a Presence in there, you know? Erichthonios is definitely also thinkin’ about mom while he jerks off to his dad fucking his boyfriend. What a mess.

Either during Endwalker (during their time as hostages) or post-Endwalker, Jullus either:

1. jerks off while imagining having both the twins at once
2. jerks off while watching the twins have sex, either just on the visual or imagining himself in the middle of it

He’s very ashamed of it, but he can’t help himself. Up to you whether the twins know what he’s up to. Big emphasis on the conflict between the semi-unrealistic/outrageous fantasizing of a young man and the guilt he feels because, well.

I’d love to see Athena commanding the memory!Erich to have sex and Erich complying.

(I’d love love love it if she also forced Lahabrea to watch, but that’s completely optional and maybe another prompt altogether?)

We know the first brood don’t care about incest, because Bahamut/Tiamat is canonical and Midgardsomr has nothing bad to say about it. We know that Nidhogg first started his vengeful crusade against Ishgard after Ratatoskr was killed by Thordan and his knights. We know relationships between humans and dragons are possible, because of Shiva and Hraesvelgr.

[…]

They’ve come a long way thanks to being forcibly thrown together like two angsty, drenched cats in Abyssos, but more or less a decade of avoidance and festering loathing doesn’t just vanish overnight. Making up for lost time turns into the two of them bickering as ever, and Lahabrea is forced to face the harsh reality that he doesn’t quite know his son at all, always insisting on treating him as a weak, dependent child, even as he stands before him now as a man. Mutually wounded and raw from all that’s happened with Pandaemonium, the two knock horns perhaps even harder than they had before - and to make matters worse, Lahabrea finds it all the harder to see his son’s eyes narrowed in anger, glowing their fulgent red, and not be reminded of the same passion that had filled his mother’s.

[…]

AU where Aymeric is given to the clergy and raised as an altar boy, rather than the Borels taking him in.

[…]

We know Lucia and Livia are sisters. We know that Lucia was a Garlean spy when she first came to Ishgard. We know Gaius took them in (or at least, Livia in) when their parents were killed. Livia takes to their new foster father rather too quickly. Lucia has her doubts, and her relationship with her sister is becoming increasingly strained as a result.

Gaius wants to bring Lucia into the fold.

Livia has her own ideas about what that means.

Lucia wants her family back, but this isn’t her family.
