Смокчи свою власну сперму

I work on the slave normally without him having the slightest idea of what I intend to do with him. The nipples are played with nicely and he has to suck and suck a thick rubber cock very deeply. At some point he has to show that he's good at it on a real cock. At some point he gets a rubber on his tail which I then vigorously anwichse until he squirts. All the sperm was caught and the slave still has no idea that he now has to suck the entire load out of the rubber. In addition there is a lot of snot in my face, what a delicious mix for the slave.
