Hatsune Miku the Pent-Up Idol

Hatsune Miku, but with a massive donger. Publicly, she's the perfect idol. Reviving the dead industry when she rose to stardom, she's conjured up a pure, wholesome, kind and exuberant public image. In reality, there's something the public doesn't know about her. They realize she's a futa, but they don't quite realize the sort of futa she is. She's secretly fighting back perverted thoughts all day from her massive libido, using her little free time to either have hardcore sex (usually with a fan) or jerk off furiously. You'd think due to her status she'd have loads of people pining to be in relationship with her, but not many people can actually handle her sexually. Can you?
