WHAT COULD I SAY TO HIM ABOUT THE SUMMER?

...met 2 months ago...asks me to hang out w/ him and have lunch...never got to go anywhere bec. of school work and time constraints in the way...just kissed me for the first time last week (i'm uming he's interested so we're off to a good start) sooo how could i hint towards spending time w/ him over the summer? how could i ask indirectly?
