After finding out what happened to White Tiger, the beautiful Emma Frost prepared herself by transforming into her diamond form and entered Setsuna's tuff.
Hopefully the tall blonde knew what she was doing.~
Four days. Four days of demon cock and cum. Every hole of her used, and every inch of her filled. She gagged on Setsuna's cock in the middle of a ritual circle. If there was one thing her studies taught her, it was to not reject any power, or at least consider it. The demon cum had changed her, and while she hadn't lost her mind, she wanted more. Her mate needed more.
She moaned hard as the circle glowed. Red lines on her body flowed with power, and she could feel how she was being changed. Her powers being amplified, and her baby changing. Her breeding was thorough, and her moans around Setsuna's cock only excited her.
Her eyes rolled back, and wings ripped out of her back. Pain and power hit her, and she came from the sheer assault. Cum filled her throat, and she used her powers to encourage Setsuna, to break her harder. Her tits and ass grew even bigger, waist just a hint smaller. She was a beauty, and his cum only sped up her transformation.
'Bond me. Make me your queen.' She was no longer the white queen. She was the succubus queen, and as he picked her up and slammed his cock into her, she wrapped her arms and legs around him. Her moans fulled the room, and Setsuna's cock felt even better. Horns and a tail sprouted from her back, and Setsuna looked into her eyes.
"My demon queen~." He fucked her harder, and as the transformation finished, she let out a primal call, cumming just as he filled her womb. This was a new world, and she had so many more slaves for her husband and her to play with.
