John covers up, for now

"Fine" John sighed as he sat down, grabbing a tea towel from the counter behind him to cover his dick.

His mom grabbed the dice and rolled, the mist in the gem shifting to display a 6, her token began its journey, eventually settling on a black square. The mist shifted again "Our first game that includes you all, who will rise and who will fall? Pick an opponent you think you can defeat, the other two each other must beat"

Claire thought for a second "hmmm, who do I think I could beat? She looked around at her family "the game is clearly sexual in nature so I'll pick the least experienced, that might give me a shot at winning. John, you're my opponent"

With that a flash of light engulfed the table.

When it cleared John found himself standing in a small bedroom, in front of him was a large bed, on which sat his mother, still in her sexy underwear.

"The game is simple" a voice from nowhere proclaimed "you will each find yourselves able to orgasm repeatedly with no recovery time. The winner is the person who cums the least" with that a large clock appeared on the wall, displaying 45 mins. It began counting down.
