|How about Spice and Wolf by HASEKURA Isuna? The plot might be economy-driven but the main couple's unresolved sexual tension fuels the undeniably best banter I have seen so far - in both manga and anime.
Another one with great dialogues and lots of teasing is Prunus Girl by MATSUMOTO Tomoki. I really loved this manga for its episodic and hilarious storytelling.
Spoiler (mouse over to view)
The premise is a bit unconventional - Aikawa's true gender is actually never clarified - but seeing as you don't mind different sexual orientations, you should give it a try.
My last recommendation would be KAJI Eiri's Keishichou Tokuhanka 007. The story is very light-hearted, and the main characters' interactions with each other are enjoyable to follow but I'm not sure if it is because of their flirting or just because of their chemistry.
Apart from these, you could also try searching for tags like "Flirting" or "Character Who Bullies The One They Love" (I remember a tag called "Character Who Teases The One They Love" which might have just been what you're looking for, but unfortunately, it seems to have disappeared somehow).
