How to ask a girl to come over, without implying sex

saulwhite
I've been dating this girl for a couple of weeks (5 dates), she made it clear that we won't be having sex until we're "official" (which I don't mind). Everything is going perfect we have fun, we both like each other.

We both live with our parents, so all our dates were outside. This week, my cousins are leaving town for a week, and he will leave me his house.

I want to invite her to come over. I was thinking of cooking something and then watch a movie, or something like that. The thing is, I don't want her to think that I want her to come, so we can have sex. (I know she won't come if it's for sex). So how would you ask someone to come over, letting her know that is just dinner and a movie, there will be some making out of course.(She can sleep over, we can kiss, cuddle, everything but sex).

Notes: I do want to have sex, but I respect her decision, so I really want her to come over the house, so we can be alone and enjoy the night.

She came over, we ended up having sex. She was the one who initiated it.
