お姉さんと一緒

You are attending a one-on-one fan meeting with a downer Vtuber older sister.

She seems to like you very much, and you end up spending the night at a hotel.

Let's captivate her body and soul with your extraordinary play!

The controls are simple.

Just drag the smoothly animated character with your mouse using Live2D.

As the game progresses, her heart will soften, and she will surrender herself to pleasure.

Game System

Full animation with Live2D! You can drag various parts of her body, such as her head, chest, and thighs. By dragging different parts and moving the mouse in various ways, you can provide different kinds of stimulation.

The speed of the strokes and the combination of vertical and horizontal movements will change how she feels, so try out different combinations.

She will react in real time to every operation, and erotic animations will play.

Her reactions, breathing, and sound effects are fully synchronized with mouse operations.

Emotion Engine

Expressions change automatically based on three parameters: teasing, pleasure, and intensity.

Sudden intense movements will cause her to feel more stimulation than pleasure, making her moan even more.

Start gently at first, and as she gets used to it, she should be able to enjoy more intense play.

Customization

You can freely adjust expressions and outfits. Try customizing her expressions to your liking. Additionally, you can set steam, chest and genital size, and male transparency.

Recording function

You can export play videos as MP4 video files.

By transferring the video to a smartphone, you can enjoy it anywhere.
