Warnings: Yaoi, mpreg and Yuri if don't like then don't read. Multiple pairings inside... A collection of one shots so complete yet will still have updates.

Every year, the Kiryuus and their twin sons Ichiru and Zero go to visit their old work friends, the Kurans. The Kurans have two children, Yuuki and Kaname. Ichiru and Yuuki quickly fall in love, and Zero and Kaname, lets just say, take a little longer. But they get there eventually. Story only revolves around Kaname and Zero though, so hardly any Ichiru and Yuuki.
