There are seven mangas in this series, both spin-offs and sequels, that show a family of guys that turns out to be nearly all gay.
14+ series of manga focused on students from one school and their family members.
Any BL manga I've read that has less than 4 spin-offs based on it. If it has more I probably made a separate list for it.
