This was a simple game that they played often in the family. There were very little rules, really, and those that existed were shady; merely lines, drawn in the sand. A gently breeze, a fierce fire, and the rules were gone.
For instance, there was the Christmas of 74', where they were too many relatives and too much alcohol, and so much cheer. Naturally, the younger children even managed to sneak a couple of shots, and from that, they were tipsy enough to wander off into the garden, where they had gathered. The five of them sat in a circle, staring at each other, before the eldest boy stood up, mumbling vaguely about getting more alcohol, and bolting out. The middle girl, uncomfortable with the heat, dragged her younger sister with her as they went back in, ready to brave the relatives in return for a few moments of comfort.
Awkwardly, he shifted from side to side before stammering to her. "I…I need to go back in!" before scrambling up, cursing the fact that he could never get the easy elegance that the rest of his cousins were born with. Unfortunately, judging by the sly smile on Bellatrix's face, there was no way he was leaving for a very long while. Gulping, he wondered what the older girl wanted. Perhaps she would leave him alone after a few hexes? Or would she give him a black eye?
Stalking towards him with an unnerving, feline grace, Regulus stared warily at her. What did she want? Her fey, dark eyes drilled holes into his mind, and she smiled, leaning forward to whisper, her hot breath caressing his ear, a seductive trail of words worming its way into his mind.
"Want to play a game?"
