King Philip V of Spain (1683-1746) and his court liked to play a game called El Impávido (The Imperturbable). Basically, a bunch of men bottom-naked were sitting around a table, which was covered by a cloth. A lady was under the table and sucked one of the men's cock. The rest of the players should guess who was being sucked. If their guess was correct, the other
player had to leave the game. If it was wrong, he would leave. The game was won by the
player who would
cum in the lady's mouth without the rest of the players noticing.
Apparently the game was very
popular among the French nobility in 18th century.
