god i love your magridalcest omegaverse concept i am invested in the luisa isabela mirabel plotline, *especially* with the idea of isabela and mirabel mking certain that luisa is being cared for.
isabela making luisa *ask* for what she wants so that they can treat her as she deserves and just. going until luisa fully can't speak anymore and is just a whining mess.
Yes!! They're so gentle with her but so firm at the same time, making sure that she knows that it's their turn to take control and that all she needs to do is lie back and tell them what she wants.
Luisa has her head in Isabela's lap while her big sister is whispering compliments to her (telling her that she's so sweet and kind and funny and beautiful and does she even know how incredible she is to them? that she's more than just her strength?) and Mirabel buried between her thighs, and she's in tears from the overwhelming pleasure and relief of just giving someone else the reins.
Has she ever felt this loved before?
And when it's all over, and she's a boneless heap of tears on the bed and her head is filled with clouds, Luisa still tries to get up onto shaky legs to take of her sisters. Only for Isabela to very firmly push her back down, reassuring her that they've got this, and then she and Mirabel just spend hours gently pampering their sweet alpha sister with food, water, gentle touches, and soft kisses :)
