(Sorry changed the prompt a bit)

There's this....game that they play. Centered around a resort that gets enough rich bastards flowing through it that they've learned to turn a blind eye to quite nearly everything going on inside it. They found the place when they were still New, still getting used to the boredom that follows immortals around, hanging over them like a new form of death. They were loyal to each other, of course they were, but when you are promised eternity together, your eye begins to wander. The first time he brought a mortal into their bed she hadn't been angry, more contemplative. They'd left the resort that same night and took a good ten year break together in the countryside of France. Eventually though, they returned and with a new game in mind to spice up their ever lasting lives.

They'd spot out a mortal together, send in one of them to garner their attention before swooping in together. They'd play with the mortal for a while and then they'd let them go. Eventually, this too began to bore them. As is the case for immortals. So they found a new game. They took to arriving at the resort separately, individually taking a mortal and enjoying them for a while before returning to each other again. At first only a week, then a week grew into a month which turned into months and eventually a year. They'd always return to each other's arm though, ready to share all that they had done and learned. One year stretched into three and before he could blink they had been apart for near fifty years.

He'd already finished with his last fling, a paltry thing that didn't entertain him nearly as long as he thought it would. He had come down to the beaches of the resort to search for his next when he saw her. His love, his other half. The being he swore to spend eternity with and she looked just as beautiful as the day he'd first met her, all those thousands of years ago. A cunning grin grew on his face as he approached her. After all, absence makes the heart grow fonder.
