Help Me, Teacher
Threesome situation between a late-bloomer omega and two alphas. The alphas basically try to one-up each other when it comes to "ownership" over him, only for it to eventually dissolve into a sharing situation. It's fun; all the characters have chemistry with each other, even though the alphas aren't involved with each other.

Just chapter 1, skimming around. Interesting portrayal of ABO---pheromones seem much more uncontrollable, more...animalistic. - Omega son gets incorporated into primarily Alpha household, with only a beta butler as accommodation. He's determined to work hard under the family and become a great butler. Unfortunately, with uncontrollable pheromones, things get... awry.
Oblivious Mr.B
Beta MC's just a good guy all around. Does the work, gets shit done. Bumps into ML who's apparently in heat, they fuck, and then MC takes responsibility for him. Not much else, rather low stacks, honestly. spoilers --- oh right, turns out the Omega is actually an Alpha (and I think his boss/superior?)
Takatora-kun to Omegatachi
Chapter 6. A bit hard to read---veiled allusions to feminism are heavy, almost too on the nose---but I find the discussion refreshing. Not entirely sure where this'll go. On hold.
