Red Son wanted the connection. He wanted the claim. He wanted to be close with MK, and he wanted to give in to him, especially in this dangerous form that hit his every instinct. The power, the strength, the edge of danger, how much the other could hurt him if he wanted, if he hadn't wanted Red Son.

He feels the other push in, claws digging into his back, head falling back with a gasp, eyelids fluttering closed as the pleasure of being filled hits him. Fire flaring from the candles brightly as a deep, loud moan spills past his lips. The sound turning to a keening whine as he pressed in and in and in, as pleasure made her tighten around him. "Fuck, MK~"

Red Son half opened her eyes to look at him, sees his exposed neck, growling with need before moving up to kiss and nip sharply over his neck. "Yours-all yours-feel so good~" She panted against his neck, hips angling to help him push in easier.
