Blowjob Roulette with a Twist. MFF.
 

This is for two ladies and one gentleman. The women will start by taking turns giving the man oral, switching every two minutes. The one who makes him climax loses and must swallow and keep going. Meanwhile the winner climbs on to the man's face until she climaxes. Afterwards the girls switch until the loser climaxes as well. Finally if he can, the ladies work together to get another load out of him.
