The first time Aoi got his heat, in the end did he do it with Jirou or not? I'm kinda confused..

Nope. Jirou actually snapped out of it before he could penetrate Aoi so...
Yeah. Their first time having sex together was after the engagement party :)
It's nice to see that the Alphas of the Saionji family have a lot of self-restraint to be able to snap out of their rut.
It was so fuckin' complicated and the whole cheating things I don't like it, well it realistic but I still hate it... well, good thing it ended with happy ending I guess...
