[Kaguya] Futanari Adventurer Miyu (2D Comic Magazine Yari-houdai! Hame-houdai Niku Onaho Joutai no Kabe Shiri Heroine Vol. 1) [desudesu]

Solo adventurer Miyu marches into a dungeon rumored impregnable to rescue a missing comrade, only to find her quarry very much alive—fused halfway into a living wall with her bare rear left helplessly on display. The plucky futanari swordswoman's noble rescue attempt melts into a marathon session with the trapped elf, leaving both girls glazed and spiral-eyed beneath a crowd of eager partners. The final twist stings sweetest: the freed elf saunters off with a wicked grin while Miyu takes her place in the stone as the dungeon's newest lewd wall, destined to lure in plenty of futanari thrill-seekers.
