An 'astr sex story' might be a story that combines elements of the astral plane (a concept in some spiritual and esoteric beliefs) with themes of sex. However, it's not a common or widely known genre. It could be a very niche, perhaps even self - created, concept for a story that might involve interactions between astral beings and sexual undertones. But again, this is all speculation without more context.
There's not enough information to determine its widespread popularity. However, if it has received positive reviews from players and critics in the visual novel genre, it could be gaining popularity. Some factors that can contribute to its popularity are interesting characters, a well - written plot, and appealing art style. If it lacks in these areas, it may not be very popular.
Since 'astr sex story' is such an unusual concept, here's a possible example. In an astral realm, there were two energy forms that were attracted to each other. They began to interact in a way that was similar to sexual attraction on the physical plane. Their union created a new kind of energy that affected the astral environment around them, causing it to glow and pulsate in a way that was a result of their astral sexual encounter.
