I loved Yellow (not the new episodes) and I like Blue Sheep, Makoto Tateno is a pretty good yaoi author. His latest A Bloody Kiss Tonight was about vampires.
There are three vampires, each alone, the oldest Keito is obsessed with a certain man, every 50 years or so this human is reincarnated and Keito finds him, then ultimately ends up being killed because of him, I guess you would call him a slight masochist. This current reincarnation is different though.
The second story is about a dhampir and the vampire who can't stop himself from taking the little dhampir. But dhampir blood and fluids is poison to vampires and soon he grows weak.
The third isn't really a story but a brief glimpse of what could be a second volume, the third and youngest vampire (who usually goes for women) sees a young boy dying from a lung disease and saves him, it's only a few pages, but is sweet.
This yaoi was a little different then what I'm used to with Tateno. Usually he spends all volume building up the relationships, but in this one the humans are sort of thrust in a captive/sub type position and the vampires are a little heartless. Granted they don't have human emotions but still I would have liked to see actual fondness first. I'm also not too sure why they can suck blood and eat roses, but perhaps that's a legend I'm not familiar with. The scenes between the couple are slightly rushed but very nice in true Tateno style. All in all worth the 8.73 Amazon price and I'll be looking for a sequel.
