I touched this girls butt..

So, earlier today I had grabbed this girls butt. And me and her are really good friends. She calls me names and I call her names. She has a really good butt, so I couldn't resist. But when I did, she laughed and smiled at me countless times and told me to stop in a flirtatious tone. It sounded like she actually liked it. But she didn't get mad at me and or told me she doesn't like me doing that, or she got annoyed. And she has already said she likes me, and I like her. She has also grabbed my butt countless times. Does she like when I do this? She never got mad at me, and I done it a couple times more.
