彼女はシャワーを浴びながら、もっとオマンコを指で弄るのをやめたのでしょう。

I bet she's thinking whether she should just continue rubbing her clits to wherever it might lead. Checkout my girlfriend showering in the bathtub and touching her firm titties and pussy seductively. She's horny, I'm surprised this didn't escalate to a full-blown masturbation.
