I thought it was an urban legend, but it actually exists. At the Mibiruoka Driving School, there's a rumor about an instructor named Sano (pseudonym) who uses male students with a virgin vibe as an outlet for her sexual frustrations during on-road lessons. However, just having a virgin vibe isn't enough—apparently, cleanliness, purity, and a dick size that's somewhat noticeable even through pants are also required. It was tough to arrange, but it was worth it, as she gave me some incredibly slutty, top-tier sex.
