There are indeed some stories in ancient cultures that might fall into this category. In ancient Inca mythology, there were offerings and sacrifices which sometimes involved young, unmarried women. These were seen as a way to communicate with the deities and ensure the well - being of the community. But it's important to note that these were not told for 'erotic' purposes as we might think today. They were a significant part of their religious practices and cultural heritage.
Well, in Greek mythology, there were some stories that could be related. For instance, the story of Iphigenia. She was to be sacrificed, though the circumstances were more about the wrath of the gods and the needs of the military expedition. It's not really an 'erotica' story in the pure sense, but it shows how virgin sacrifice was a concept in some ancient tales. These stories also tell us a lot about the values and power structures in those ancient societies.
