The Customer Demands Tits

Actually, the slave should make money. Unluckily, he misses something for that. The customer wants to fuck a slave, who also has something to grab. My slave is fat and well-fed but his tits are not big enough. But for this case, I have a very special device. It deep-throats on the slave nips rigidly and deep throats the nips out. The pressure makes the tits erect. A very funny device and I indeed enjoy it. But why does my slave complain so badly? It really does not hurt. Oh, dear, I totally forgot that months ago, or years ago, I had given him a chastity device with spikes. Apparently, the pervert likes my treatment so much that his disgusting cock started to grow. Which, of course, is extremely painful at the moment, and he cries out as if I had pushed a hot chop in his ass. His torments amuse me. Does he blame himself for his situation? I continue with my treatment and have fun sucking his cheeks too. My laugh attack also brings him some distraction from the pain. I make fun of his red cheeks and wonder if I should let him go to the customer later, so he has something to laugh too. Well, the tits have grown a bit and his cock got holes as well. But I have done a good job, I think. My outfit in transparent leggings and a very tight latex top had certainly done the rest, so that his cock is hard. Was it perhaps a nasty calculation not to take off his device for this treatment?
