"Oh really? What did you think I would say? You were only just saying how immature I was, I wanted to prove you wrong..."

Mari can't see Dia's face, but, she can absolutely imagine it. All she has to do is press and prod a little bit, and Dia will be eating out of her hands in no time. She could take her sweet time and simply wait it out, but, if that goes on for too long, it may get a bit boring...and, if she has her like this already, she needs to keep that hot streak going. She's pouring the tea when all of a sudden, an idea hits her; she knows it's playing a bit dirty, but...

"Here, just the way you like it~"

She crosses over to the front of the table, to hand Dia her tea from the other side...but Dia may be more focused on the fact that Mari's robe is hanging quite a bit more loosely on her body; the knot is still there, but her chest is only barely still contained in the white garment. When she bends over in a position like this, the view of her cleavage is (Mari's hoping) just short of perfect.

If Mari notices this, though (and she definitely does; this is a calculated attack, after all!), she makes no effort to adjust herself. Why would she? It's just the two of them...

"So many pamphlets...we're going to go through all of them, right?"
