They promised to meet every year on their birthday in the spot where their birthday suits were all they wore for their first time together and every time since.
They'd met in that very spot on this beach ten years earlier, when life's currency was their innocence and when adults made the unbendable rules that they gleefully and wickedly broke.
Every summer they returned with their families then later by themselves, just the two of them.
They have no contact the rest of the year, just an annual date for a week of carnal bliss.
It was agreed they would meet no matter who was in their lives because this was separate and different, but if by chance one of them truly fell in love, they reserved the right to pull out.
This year, he didn't show up.
