Alpha competition

Mello and Near who are the alphas of Whammy's house wolf pack. But when a new orphan threatens Near's role as an alpha what will they do? What will happen to Near? How will the pack react to this? Warning: Lots of yaoi which means two guys together so don't like don't read. There will also be Mpreg as in male pregnancy so again don't like don't read. Rated M for obvious reasons.
