I'm not sure which specific 'bums in the attic' story you are referring to. There could be many stories with such a title or concept. It could be a local or personal story, or perhaps a story within a particular community. Without more context, it's difficult to provide the full story.
It could mean that something or someone is in a crumpled or unappealing state ('krum') and is just like the usual or typical ('same old story'). For example, if a person always complains about the same things day after day, you might say they are 'krum bums same old story'.
I'm not sure if it's widely known as such. There are many works in the gay fiction genre, and while some gain a certain level of popularity within their niche, it might not be a mainstream - known erotic fiction.
The term 'bums in the attic' is rather ambiguous. It could be a story with a social message, for example, highlighting the plight of the homeless (the bums) who are forced to seek refuge in an attic. Or it could be a comical or even a horror - related story about strange happenings in the attic with these so - called bums. Without more information, we can't really know the full story.
There's this old bus route in my town. The buses are always late, the seats are torn, and the drivers are grumpy. Every time you take the bus, it's the same bad experience. That's a real - life 'krum bums same old story'. It's just this ongoing cycle of a less - than - ideal situation that never seems to get better.
I don't know the exact main themes as I'm not familiar with this work. But generally in gay erotic fiction, themes of love, desire, and self - discovery might be present.

Vomit cartoons often have exaggerated and grotesque images. They might show people or characters vomiting in a very exaggerated way for comical or shock value.
