Playground love.

A metaphor for naive love, like the first time you had a crush on someone or kissed a girl. The excitement of a person whose thrall makes you feel helpless in their presence. The kind of love where you have no reservations, you believe in it, you're not afraid of being hurt, just living in the moment.

Alternatively, playground, as in, a place to act out without care. A sandbox within which your actions will remain confined. A woman you keep on the side, a fling, some sort of passionate but probably short lived romance. Think Las Vegas.
