Flirting

Was she saying this to be sexual?

This girl and I tease each other a lot. Once she was humming a song at work. I told her to shut up because she was annoying ( but I was kind of lowkey flirting ) and she jokingly gasped and was like “I’m gonna come over. Come to your house late at night and sing you to sleep”.
I awkwardly said “oh my gosh” because I thought the joke felt sexual in that moment and she laughed.
We have numerous history with me teasing her about being tall and she teased me about being short and comparing me to this life size stuffed animal and saying it was the same size as me which I guess is it’s own hidden joke because I’m actually 5’6. Yet she had also expressed that she’s cared about me.
Did her saying this sound sexual? Im bi and I think she could be into me.
