[Demon Slayer] Manga where Shinobu Kocho is trapped and corrupted by a weak demon due to her huge breasts

Shinobu Kocho, the Insect Hashira, discovers her lethal focus shattered when a weak demon latches onto her, drawn to the massive swell of her breasts that now interferes with combat; she whispers, "It's strange... I can tell my body is getting heavier as they've grown even larger recently, my poison shouldn't have this kind of effect," and resolves to calm herself, yet the demon's aphrodisiac lure makes resistance impossible, leaving her breathless as the creature taunts her with promises of pleasure and an overwhelming, throbbing sensation.
