OK friends, I need your help.

I read a snippet of a Hannigram ABO story and I was intrigued. I’ve never been in to ABO before but I want to give it an honest shot.

So here’s what I need:

1. A good place to go to get a good rundown on how the ABO dynamics work.

2. Good recs that do not involve mpreg. That is definitely not on the menu. They can be any pairing and I go for Top Both so that part does not matter.

Thanks in advance.
