The world is occupied by futanari dickgirls, who are voluptous women with both a large penis and vagina, as well as large asses and massive tits. A futanari dickgirl succubus, the warlock of darkness, is summoned to the entrance of a church that worships the goddess of futanari and sex and breeding. She travels through the church, meeting a follower of the goddess, who is also a dickgirl futanari. The succubus convinces the follower to give the succubus a deepthroat blowjob, and afterwards the succubus finishes, cumming in her throat and subjugating her to the succubus's will with the power of her cum. As she continues through the church, she continues to suck and fuck all of the church followers. She reaches the end of the church, and encounters the Head Bishop, an exceptionally powerful and well-endowed dickgirl futanari, the champion of light. The succubus and the bishop begin to have hardcore sex, their dicks swinging wildly. The bishop commands her followers to assist her, and they begin to gangbang the succubus, but this is all a part of the succubus's plan, as she sucks and fucks them all to completion, draining them of their cum, and therefore their power. The other followers then begin to suck and fuck their fellow sisters, railing them with full loads of cum, which provides them with the energy needed to continue the massive dickgirl orgy. The story ends with the bishop destroying the succubus by cumming in all of her holes, but the bishop eventually becomes corrupted by succubus's power, and the church ends up worshipping the succubus, and descends into a massive nonstop futanari orgy.
