[Salt choc (Nana G)] Goddess of Iron Fist vs Licentious Sea Demon (Fate/Grand Order) [=CKC=]

Saint Martha's iron fist has felled dragons and purified seas, but against a licentious sea demon she discovers the limits of holy muscle—slick coils wrap her wrists, her waist, her heaving chest, peeling away her dignity one helpless moan at a time. The demon's 'assimilation' proves thorough: her nipples, her throat, both her lower holes stuffed and stretched simultaneously until the proud servant is drooling and begging to be destroyed. By the final page she lies drenched and mind-broken, a conquered trophy the triumphant sea demon intends to make useful indeed.
