Autsuki Yuna, who cums instantly. Even just having regular sex makes her cum non-stop. I made her cum continuously without regard for her limits using multiple vibrators, thousand-handed electric massagers, drill vibrators, and multi-person play. "Stop! I'll never be human again!" She lost all reason, cumming so hard from muscle pain that she couldn't move. Yuna's pussy became too sensitive, causing her to cum non-stop.
