How do I grind with a girl?

If I'm at homecoming or something, and a girl is grinding on me, what am I supposed to do? Grab her hips, and move with her or what? I don't just want to stand there like a dumb @$$ while she's doing it, so there must be some movement from me involved. And, I'm going to get a *****, while she's doing it of course, do girls like that? I mean, I think any girl should expect a dude to get hard with there booty all on his d!ck, but idk?How do I grind with a girl?
