Saintess Eruna and the Lustful Book of Corruption ~Busty Sister’s H Services~

Dive headfirst into a world of temptation and duty in the quaint Urunka village, where Eruna, a voluptuous and devoted sister, finds herself caught in a supernatural struggle. After answering calls for help from neighboring villages, Eruna arrives at Adus Village with a solemn mission: to watch over the "Succubus Rhaenys," a seductive demon locked away deep within a cave since time immemorial. Venturing into the shadowy depths of the cave, Eruna discovers an old tome that pulses with an eerie glow, unleashing the trapped succubus in a flash of otherworldly light. Despite her fierce resistance, the succubus invades Eruna’s body, threatening to consume her entirely until her fellow sister, Aela, intervenes to save her. Yet the battle isn’t over — the succubus remains within Eruna, its influence stirring dangerous desires she must suppress. To keep the demonic force at bay, Eruna must drink a rare love potion designed to suppress the succubus, though it comes with a fiery side effect — seven grueling days of heightened horniness. Meanwhile, the lecherous men of Adus Village are eager to exploit her vulnerability, making Eruna’s path anything but easy. Eruna’s seven days of carnal endurance begin now — will she survive the relentless waves of temptation and reclaim her soul? This short RPG delves deep into the lives of two sisters — Eruna and Aela — bound by duty and desire as they confront the succubus’s dark influence. The game features a cast of eccentric villagers: a homeless middle-aged man who persistently shadows Eruna, a peculiar alchemist brewing provocative potions, a young bartender insisting she drink beyond her limits, and an elderly village chief demanding payment in flesh. Original moaning sounds recorded by the talented voice actress Kotoka bring Eruna and Aela’s intimate moments to life, enhancing the immersive experience during H events. Beyond multiple endings, including virgin clears and bad outcomes, a Memory Room allows you to revisit unlocked scenes, while quality-of-life features like objective markers and heart icons streamline your adventure. The game also includes provocative illustrations depicting childhood playmates’ sexual harassment and encounters with main male characters and random NPCs, adding layers of adult intrigue. Customize your experience with a pubic hair toggle that applies across all basic CGs and illustrations, allowing you to tailor the game’s aesthetic to your preference. As the story unfolds, unlock an ending room dedicated to main male NPCs where you can explore their locations, engage in post-corruption dialogues, and savor additional H events. Gameplay centers on exploration and strategic decision-making, especially regarding whether Eruna drinks the love potion each day to manage her lust and avoid full possession by the succubus. Lust and Corruption stats evolve dynamically — as Lust rises over time, it raises the ceiling for Corruption, gradually transforming Eruna from pure to increasingly lustful. You can also step into the role of Sister Aela to witness events unfolding without Eruna, where her own experiences remain unaffected unless she engages in H events. Unique costumes, including a cow outfit worn by a childhood playmate, and specially designed attire for male characters, enrich the visual storytelling and tie into the H events. Prepare yourself for a captivating blend of sensual storytelling, strategic gameplay, and vivid characters that promise an unforgettable seven-day journey through lust, resistance, and fate.
