I can imagine Mycroft leaning over and whispering in the curve of Greg's ear, "You only know what I want you to." He's broken hearted that he can't tell his lover everything. He wants to open his heart and self to this amazing man, but his whole life has been constructed on secret keeping. He would risk the sanctity of the whole world for the love of this man.

Then Greg looks up into Mycroft's warm eyes and leans forward, mouthing into his skin, "I know everything you don't want me to." Because he can read Mycroft's life in the creases around his eyes and the way he rubs his forehead at the end of each day. He understands the need for private thought, but their minds have been melded so close he can hear him breathe when he's on the other side of the world.

Mycroft kisses Greg's lips, sweet and gentle. These lips that could pry the last bit of resolve away from him, but choose only to love him. He breathes against Greg's mouth and out escape the words, "Your mouth is poison, your mouth is wine." Wine to drink and forget the world around and poison to kill the man he used to be.

Greg can only respond, "You think your dreams are the same as mine" and he's right. He knows he'd rather spend the rest of his days here in the arms of this amazing man, this great, adventurous love, than anywhere else in the universe.

And lying there, they both try to insist the words are true, "Oh I don't love you, I always will." But that's a lie. Never has there been a love full of so much abandon as this, a love that would risk health and safety and the sanity of the world because nothing is as precious as that next kiss. And nothing ever will be.

And Mycroft knows that he leaves, every time it's him who will run away and he holds Greg to his chest and cries into his hair, "I wish you'd hold me when I turn my back." And he knows he will. He knows Greg will always wait for him, whether it be for a moment or a thousand years.

"The less I give," Greg speaks against Mycroft's warm chest, "the more I get back." He's afraid that he's the one who's gone. that he's the one distracted and forgetful and he may not be the first to act, but he loves Mycroft with all his heart. He wraps his arms around him, pulling his body close and listening to his heart and thanking God or fate or Love, what ever brought this man into his life.

Mycroft pulls Greg's hands off from around his body and holds them together between his own, pressing them to his chest and looking into Greg's eyes. He says, "Oh your hands can heal, your hands can bruise" but they are always a blessing to me. There's violence in Greg's life, Mycroft knows, but he's never felt safer—not surrounded by an army or a thousand body guards—than he does when he's touched by these two hands.

Greg will close his eyes and breathe deeply as a tear rolls down his cheek. Mycroft closes the distance between them to kiss the water off his lover's skin. In that moment, Greg will open his mouth and in a voice just louder than the rustle of a bed sheet, he will say, "I don't have a choice but I still choose you."

And both men sing into the future and all the times they will spend just like this, lying in each other's arms and whisper, "I always will."
