You thought you got summoned? No— it was your cock that got summoned! (Male POV)
You were summoned to another world to become the hero who would save it... That's how it was supposed to be, but the female priestess who summoned you lacked the ability, so in the end, only your penis was summoned to the other world. Velmaria is a medieval fantasy world inhabited only by women. In this world, reproduction is achieved through saliva-based conception, so the very concepts of "men" and "penises" are entirely unknown to its people. The human faction, known as the Radiant Dominion, is a coalition of humans, elves, dwarves, and demi-humans under siege by the Abyssal Covenant, a nation of demonic women and monster girls who seek to annihilate humanity. Desperate to save their crumbling world, the Radiant Dominion attempts a forbidden Hero Summoning ritual. However, due to the inexperience of the only priestess who knew the spell... only your cock was summoned.
