Synopsis
The Labyrinth of Milking
Deep within a frontier cave stands the Labyrinth’s Essence Cup. It is said that by filling it with magical energy, one can obtain immense power.
Inside this labyrinth, magic operates under a special law: the stronger your futanari member, the more powerful your magic; and the larger your breasts, the more spells you can unleash. Magical power dwells within sexual functions. In other words, filling the Essence Cup with magic means… continuously offering futanari fluids to the cup.
Filling this massive Essence Cup with fluids is no ordinary feat. However, by exploring the labyrinth, you can grow your futanari member to be stronger and more robust — and your breasts as well. But do not let your guard down; the monsters residing in the labyrinth will relentlessly attempt to make you waste your fluids through unauthorized ejaculation. Such fluids must be offered directly to the Essence Cup.
As a seeker challenging the cup, you must explore the labyrinth, train your futanari member and magic, kick aside the monster kin, and focus entirely on pleasuring your futanari member in front of the Essence Cup.

Offer Futanari Fluids to the Essence Cup
In Extraction Mode, you can stimulate your futanari member through various means to offer fluids to the Essence Cup. Other areas can be stimulated as well. By reaching a climax in a more pleasurable state, you can extract a large amount in a single session. Naturally, as the futanari member grows larger, the volume of the release increases further. Exploring the labyrinth will provide ways to increase its size.
Explore the Labyrinth to Strengthen Your Futanari Member
In Exploration Mode, you can challenge the dangerous labyrinth. Inside, you can obtain magic and items, and most importantly, increase the size of your futanari member. Your breasts can be enlarged as well. If you return safely before the day ends, you can enter Extraction Mode immediately.
Come to think of it, the original purpose of coming to this labyrinth was for magic, not the futanari member… well, no matter. Extraction is more important than that.
Beware of Monsters! Combat Ability is Crucial
Monster kin swarm inside the labyrinth. They relentlessly target the futanari member, seeking any opening to force a wasted ejaculation. If forced to release, you will lose the fluids intended for the Essence Cup. In this labyrinth, all physical damage is converted into pleasure for the futanari member. Returning safely means successfully enduring the urge to ejaculate.
To achieve this, you must learn magic and prepare for battle. Curiously, in this labyrinth, you can learn magic instantly just by opening a book. Utilize various items and spells to survive.
However, focusing only on extraction will leave you short on fluids, while focusing only on exploration defeats the purpose. A balance between extraction and exploration is vital.
A Labyrinth that Changes with Every Challenge
Even if you are kicked out of the labyrinth, you can challenge it from the beginning as many times as you like.
The terrain changes every time, but your knowledge will not betray you; you will surely begin to see a path forward.
The spells learned from grimoires change randomly each time. Whether it is a spell you are looking for or one you haven’t seen yet… it is always better to learn them. You can choose to use a variety of spells or master a single one. Try out different builds with every challenge.
Success! A treasure chest. You cannot carry many items, so deciding when and where to use them is important. Of course, you could leave them behind and come back for them later.
Abilities and specialties change depending on the explorer. Choose based on your playstyle or your preference for a specific futanari member. Regardless, everyone is still after the magic.
What awaits in the depths of the labyrinth…?
Some seek magical power, some follow a dream, and some challenge the labyrinth by chance. Without knowing that it is a lewd futanari modification dungeon crawling with monster kin —- What truly lurks in the depths, and will the seekers fulfill their ambitions? The Essence Cup simply stands there, waiting for futanari fluids.

Editorial Review
The Labyrinth of Milking plants itself squarely in the hybrid action-adult game space where dungeon crawling mechanics intersect with progressive sexual transformation. It’s a relatively uncommon approach: most futanari-focused adult games lean toward visual novel narratives or static CGs, while this work prioritizes mechanical progression tied directly to erotic stat-building.
What distinguishes this here is the core conceit that physical attributes function as gameplay systems rather than mere flavor. The rule that futanari member size correlates with offensive magic power and breast size determines spell capacity creates a feedback loop where sexual growth feels mechanically consequential—you’re not grinding for arousal’s sake, but to unlock tactical options. The secondary threat mechanic (monsters triggering unwanted ejaculation) introduces resource management into what could otherwise be passive content consumption. The animation and music tags suggest this isn’t a static visual novel; the production leans toward active, timed interaction. The Application tag indicates standalone executable software rather than a browser experience, which typically means smoother performance for animation-heavy sequences.
The English localization expands its potential audience beyond Japanese-only speaker communities, though the synopsis’s slightly awkward phrasing hints at possible translation compromises.
This appeals most to players who appreciate mechanical depth in adult games—specifically those who want their fantasy progression to feel systematically integrated rather than cosmetic. If you find the standard “collect CGs through stat checks” formula exhausting and prefer when sexual content drives actual gameplay decisions, this design philosophy should resonate.
A genuinely mechanically-minded take on futanari fantasy that refuses to treat body progression as purely narrative window dressing.
