This Evil Dragon Is No Defeated, Captured Princess

There's a saying among dragons:

To become a dragon who can stand on her own, you have to capture a human girl and lock her in a dungeon, then force her to love you.

This rumor has been driving me crazy.

In the end, I made a decision that would shock all dragons.

I would personally turn into a beautiful girl and pretend that I'd forced myself on me. That way, I could show off my glorious achievements!

But as soon as I transformed into a beautiful girl, another dragon captured me.

[Hey, little girl, you're adorable. Be my prisoner!]

[Wait, I'm an evil dragon! An evil dragon!]

But the fire dragon big sister didn't give me a chance to explain.

She even wants to take me to a tea party and show the other dragons her darling little wife?

How could a dignified evil dragon like me be conquered by a fire dragon?

But I can't reveal my identity, or I'll be humiliated for life!

Maybe I should use my evil dragon identity to cuckold this bad big sister? I could say I've been with the evil dragon big sister for ages. It's still me either way, so I can make up whatever I want, right?
