>>40139317i didn't, but i'm about to
here, how does this look? (should i put it in the thread now, or should i refine it?):
bonnie gets curious about serena's more developed body and somehow convinces serena to let her see it; serena could be embarrassed or reluctant because of wanting to "save" her body for ash or some other silly thing (maybe bonnie could comment on serena's underwear, breasts, etc.)
bonnie or miette "doms" serena (again, maybe because of the topic of ash)
story about serena and miette where both girls have their competitive sides go into overdrive; they try to humiliate each other
(addendum):
they each start by being super embarrassed to do anything lewd; miette's lack of her usual smugness could be brought up here
by the end, competitive drive leads both to blow out all their holes, indulge in bizarre fetishes, and devalue themselves for the pleasure of others, all while ash has literally no idea what's going on
(sorry if it's garbage)
