A/n I just could not get this one-shot out of my head, since I heard about Dumbledore being gay. And also just to clear this up I don't think that in canon Dumbledore had a sexual relationship with Grindlewald, but merely and intellectual one with him. But this was too good of an opportunity to pass up. By the way this features canon Deathly Hallows except that Snape was bad and was two timing Dumbledore all along.
He was perfect, the dark tall form of his man. Gellert Grindlewald had beautiful black greasy hair, but he had the most darling eyes. Those perfect red eyes. "Oh he is so perfect, and he is all mine." That is what Dumbledore thought of as he danced with grindlewald.
The music suddenly stopped and they were nose to nose. They both said I love you and kissed. Then Grindlewald pushed Albus onto the bed and tore off his clothes. Grindlewald jumped on top of albus and started to pull his trousers off with a mischievous grin on his face.
Suddenly Albus woke up. For the rest of the night all Albus could think of was, "I wish that dream had continued for another minute." For you see Albus had never seen his lovely Grindlewald completely unclothed, and he relished the thought of when that day came.
"Ill make sure to have sex with him tomorrow." Albus reasoned with himself. But he never got to because the next day right before he was going to ask Grindlewald if he wanted to do it, they got into a fight and Ariana died. For the rest of his life Dumbledore's biggest regret was not going to see him the night before. In fact when Dumbledore said, "Severus please." On the astronomy tower the night he died he meant, "Severus please let me live until I go to Nurmengard and have sex with Grindlewald, and then I will let you kill me." But he could not because Harry was under the invisibility cloak, and he did not want Harry to be exposed to that part of the human life yet.
