Overview:
Aoi, the succubus who appears aimlessly in the dead of night. Whenever she finds an “otaku” struggling with his pent-up desires, she takes pleasure in slowly cornering him—tormenting him until she has drained every last drop of his essence. She is a true lewd demon who lives for the thrill of the “full squeeze.“

[2 Months of Intensive Overhaul] A complete ground-up reconstruction of the programming and animations.[Full Interactive Animation] Every movement is fully controllable at the player’s will.[Ultimate Seamless Experience] Experience overwhelming immersion with buttery-smooth transitions and fluid motion.
【A two-month complete overhaul 】Live2D is captivating, providing the ultimate in vividness. The program and animation are optimized from the ground up, and the fusion of multiple layers creates a "never-stopping" dynamic feel. From facial expressions to fingertips, melt-in-your-mouth movements will seduce you.
The action switching is incredibly seamless. All movements are at your fingertips. An overwhelming sense of subjective immersion, as if it were realistically disturbed in front of your eyes.
Full animation throughout. Swelling limbs, lewd expressions, overlapping panting――. The waves of pleasure surging in from the subjective perspective drag both the eyes and the senses to their limits.
Succubus Aoi Ya (Aoya) will serve you with his whole body to make you cum. Now, together... let's go crazy until reason disappears――.
Operation Description:
(1) Left click on the penis part to start/stop the action.
(2) Right-click on the penis part to switch between insertion and removal.
(3) You can toggle the intersection action with the button on the right side of the screen. During operation, you can adjust the intensity of the action with the mouse wheel. There are five sets of mating actions available, giving you a total of 32 different actions to enjoy.
(4) Some actions are released when the succubus' climax level reaches a certain value.
(5) The button on the left side of the screen allows you to switch between succubus climax ejaculation modes (no ejaculation/creampie/out).
(6) The mouse follows your gaze, causing your head and body to sway slightly, making it seem as if you are really staring at them. When you combine gaze following during intense pistons, the immersion soars in one fell swoop, with the physical tremors of your chest in particular becoming boldly bouncy, and the voluptuous eroticism is conveyed throughout your body――.
Immediately after the start of the game, the main character is a "weak ○ po" who gets scared even with the slightest provocation. Aoi Ya (Aoya) said, "Oh, it looks like you're going to come already? ...Weak (laughs)" it starts off lightly.
So, increase the strength of the chi○po by repeatedly stopping it during sex. As the intensity increases, the upper limit of the ejaculation gauge increases and the sensitivity decreases. The launch stock also increases, and gradually it grows into a "tolerable ○ po."
The more you make Aoi-ya cum, the higher her orgasm level will be. New positions and more erotic movements are released. The trick is to look at the situation and choose the moves, as each action has a different "how ejaculation builds up" and "Aoi Night's excitement level."
If you think you're nearing your limit, stop moving or pull out and run away. If you ejaculate even once, your stock will be 0. The game is over immediately.
But the more you train, the more you can make Aoi-ya cum over and over again. It's up to you to make her happy.
※Additional explanation
(1) During waiting, the ejaculation gauge and succubus' excitement level decrease more quickly when the body is in a state of withdrawal than when the body is in a state of penetration.
(2) When the excitability of a succubus drops below a certain value, the accumulated excitability stage up to that point is reset.
(3) When both penis strength level and succubus climax level are at their maximum,
Three locking functions are released: "Ejaculation Value Lock," "Excitement Value Lock," and "Excitement Stage Lock."
This allows you to play a variety of mating patterns in any combination.
(4) If you find it difficult, here are some tips. There are also "little jokes" (Easter eggs) hidden all over the place, so be sure to find them yourself.
This game uses the "Live2D Sex System" where all actions are fully dynamically linked. Switching positions and movements is incredibly seamless, and at any given time you'll naturally transition to your next action.
The animation is finely layered, with the lower body joining movements and the upper body movements and facial expressions acting independently without interference. No matter what position you use, you can freely combine a wide range of facial expressions.
Facial changes are not simply position-dependent, but are controlled in real time by internal state machines. Therefore, even the same action will give you a different reaction and sex appeal every time.
Furthermore, through gaze following and physical calculations, the chest shaking, body reactions, and mysterious gaze change subtly every time, allowing you to experience every moment as "living sex." Experience the immersive feeling of your body shaking finely or shaking wildly as the piston moves in and out.
If you are looking for a deeper immersion, we highly recommend using it in conjunction with a masturbator. They will snuggle up to your lonely night and make you feel good until the very end.
◆ Regarding future updates, the initial version will focus on the core of the "Stopping Sex Experience with Aoi Yoru." Even after the release, based on everyone's feedback, we will continue to actively consider updates that will enhance the feel of the game, such as enhancing motion and adding additional effects.
【From a new developer: Regarding future updates and voting】 I'm a new developer, so I've just opened accounts on various platforms and some are currently applying. Future free updates (including the addition of motions, costumes, accessories, and physical features) will be prioritized through user voting. We will be implementing each of the "things we need most right now," so please join us in the production.
