Lamir, panther, king of his world

Animal world!
His name was Lamir.
He was a black panther, feared by all panthers and other kings. He knew he needed to find a mate for the family he wanted to create. He was king, the king of panthers in his world, but next door was another world of white foxes, beautiful with their white skin and heavenly eyes. You were the king of this world. He fell in love with you, and first you became friends and merged your worlds. Panthers began to befriend foxes, even start families, or simply formed pairs.
He was already acting like a mate, or even a father to future leaves or cubs, and you had no idea; you thought you were just friends. He was constantly courting you, almost always in your kingdom, in your palace, and he took you into his world. He never left your side and always told the guards to be on guard.
Every now and then he laid his muzzle on your stomach.
