A/N: It was bound to happen sooner or later. Only, it is something that could destroy them both.
One thing leads to another, like they usually do.
In the end, it's all very exciting and passionate and Alfred feels that if his heart was still beating, it would burst; he wouldn't have expected to find such fire in the older vampire. There's desperation about the way Krolock touches him and Alfred isn't sure what it all means, but it's almost like it was the last night of their unlives and he is trying hard to make it all count.
He wonders how his blood tastes to Krolock, and if it's as pleasurable for him as it was for Alfred. At least he thinks that the low groans are sounds of delight, and the deep rumble of them is somehow very exciting and makes him yearn for more. After Sarah, this all is very strange yet thrilling, and not only because it's not a woman who is with him; and he can now see where she learned all those tricks that used to drive him to the point of madness in the beginning of their relationship.
The experience is everything and nothing he would have expected, and he's glad to have it, even if in the end it overwhelms him for some reason and he ends up curled in the Count's embrace, sobbing against the older vampire's neck. He's not sure why he's crying and it's not probably something one should do after being loved so completely, but Krolock seems to understand as he strokes Alfred's hair and hums quietly.
After some time, he calms down and just lays his head down on the Count's chest – there's really not that much space in the sarcophagus. He knows it might be the only time he ever will, even with how he loves the Count and wants to see him smile, but maybe that's the point of it: he loves Krolock too much to allow it. For what else can it do for them than to destroy them both? Alfred fears their melancholies will only fuel each other until they are completely devoured... He knows how the Count sometimes yearns for the final release, how he would consider it a long-needed rest, but Alfred still doesn't want to be the one to cause it.
Nevertheless, tonight belongs to them, tonight he loves the Count more than anything, and when Alfred curls up against the older vampire and finally feels the death coming to claim him, he experiences a curious sense of peace he hasn't had in some time.
