Does she like me or does she just want to use me?

So me and this girl was hanging out with my cousins friends and she just started bitting me in a playful way. Then she started flirting and acting like a cute kid. But out of nowhere she pretended that I was giving a bj so I pretended she was giving a bj and then I sprayed water all over her to make it look like she got wet. She also opened her mouth happily and willingly when I sprayed the water all over her. After all that is over she bit me again and I dunked her but I guess I went down to low before I dunked her because her butt banged into my penis accidently and my hand slipped onto her boob but she wanted more. And as I left to go home she said bye and stuck her toungue out at me. Everything I did would get another person killed by her so can you tell me if she likes, probably just want to use me for sex, or is she just doing that for fun.
