Slave Locked In Gam Scissors

Princess Serena holds the slave vulnerably in gam scissors. His head is held tightly in position. With this the slave is totally exposed. He can only site there and wait to see what his mistress does with him. While the superior princess presses her gams together she holds his mouth and nose closed. What is going on? Is he running out of air?! Well, bad luck, because breathing is no longer permitted! The pressure on his skull and the complete loss of control is just what this slave needs. Princess Serena has him in her grip and continues to torture him mercilessly.
