[Konnyaku Nabe (Magifuro Konnyaku)] Nuke! Sentei no Futanari Seiken

A reluctant heroine discovers her summoned holy sword has a mind of its own, forcing her hand into relentless solo play and calling out her hidden futanari desires. Her thick, throbbing futanari shaft swells wider and larger with each involuntary stroke while her soft, heaving breasts and quivering thighs betray the intense pleasure building inside her. Now perfectly attuned to her colossal new longsword, she must hoist it high and unleash a massive, explosive release powerful enough to annihilate the Demon Lord Castle in one shot.
