Added cowgirl position animations (two posture variations) and transitions between them.

Adjusted the weight settings(weight paint) for the breast and fur parts of the Christmas costume.

Breast bounce triggered when clothes come off.

I tweaked the auto mode to feel more powerful and added 4 types of auto motion paths to the cowgirl (leaning back) position, and implemented a feature that automatically switches between them.

In missionary, if tits are being grabbed during ejaculation, the grabbing motion will pause.

Motion speed slows down for 1 second after ejaculation.

Initial excitement  level has been adjusted to 3.（will be overridden if loading saved data）.

Adjusted scene lighting.

Set maximum volume to 20.
