Yami no Matsuei, Souryuu/Touda, too many walls
Touda has never belonged to him. A fact he has grown thankful for in the centuries after the snake's imprisonment. Touda never bowed to him, never gave an inch to his power and passion in all the years they fought together. The lack makes him easier to forget, to relegate the discrepancies of his youth to a dark and dusty corner and let them rot.
Now, with Touda once more walking freely among them, the skeletons tried to stir. He had the Emperor to thank for silencing them. Sheering off the ebony locks locks to curb Touda's power, hiding the vibrant gold fire eyes behind the robotic visor, the Emperor took the hell serpent and pulled his fangs.
But the venom had already done it's damage.
He meets the serpent in the high mountain cave. It's a pretense to discretion and they both know it. Just as they know the chains binding Touda to the floor are a mockery, mere metal threads if he truly wanted free. Their whole relationship has been built on lies and fantasies.
Buried in Touda's heat, punishing him with pounding thrusts, he can lie to himself. He can almost believe it's nothing like before. That he does this for release, any body will do.
But when it's over there's the same bittersweet rush of a riptide in his blood. It feels exactly the same. The only difference, his saving grace, is that he can't see the fire in Touda's eyes.
