“I only want you, Theia. Always have always will and this shall never change. How could I ever want another when I possess the one I solely exist for?”“Phobos,” I call his name fondly a need to hug him and breathe in his calming scent surfaces.“I do not wish to treat you like you are made of glass because you aren't. Your body was made for me and it can handle everything I choose to give it. And this I will prove it to you.”“When?” I ask breathlessly as he ultimately turns around to meet my curious eyes. Golden rings outline his irises his beast announcing his presence and they stand as one before me. A wicked smile paints his face with a flash of canine displayed to me. A promise he gives that I will be ruthlessly devoured.“When I fuck you senseless.”~~~After years of excruciating loneliness, Phobos approached me. A frightening beast, my soulmate who emerged from within the bounds of a ruthless thundering storm. The male I yearned for. He caught me off guard and I was under the spell he cast through his ocean eyes. A spell I couldn't defeat and that very moment I knew I was in trouble. The second our eyes met I knew he would bring me endless heartache.We were childhood friends, him and I. Phobos the gentle and playful juvenile I grew up with and looked up to as a pup vanished and was replaced by a cold-hearted barbarian, he terrified me as he killed many with a blink of his eyes. No regret, no concern his beast often in control surging forward consuming his senses. They were equals.How can I connect with a beast like him? How could I make him call me his? How can I love my childhood friend who has become a merciless monster?
