It's a pose of secret talk, but it's the kind of pose that women who have a meeting at the well often do. It's like catching the other person and talking half-forcefully. Please make fine adjustments according to the situation. 内緒話のポーズですが、井戸端会議をする女性が良くするようなポーズですね。相手を捕まえて半ば強引に話す、といったような。状況に応じて微調整をしてお使いください。
