The first and third weekend of every month was what we called "Milking Day", because each master milked the semen from their slaves, but this day was very special...

I arrived with my slaves (Alfonso, Luis, and Miguel) at Julio's house, where the meetings of masters and slaves always took place, I was always one of the first to arrive on Friday afternoon; we entered the house and the slaves began to prepare dinner with great care and wait for orders from their masters, time passed between conversation and all the other masters arrived with their slaves, at the time of serving dinner, the slaves ate from dog plates, and the masters, seated at the table chatting about the milking and the weekend activities, when we finished, the slaves picked up and cleaned the table while we moved on to the session room to proceed with the milking.

The slaves arrived on all fours in the session room, each one with their chastity device and corresponding collar, they formed a circle around the multi-tube milking machine, while each master removed the chastity devices from their slaves and provoked their erection, securing it with a cock ring, and introduced a vibrating dildo into the ass of each slave to stimulate the prostate, once their hands were tied, with a 5 cm ball-gag in their mouth (a real torture) and everything ready, the milking tubes were connected to the erections of each one, adjusted and sealed around them, and Cristhian activated the machine in "Maximum Suction".

"These slaves really have milk," commented Cristhian, after hearing, 10 minutes later, the second ejaculation.

"I believe it, Cris," I replied - "They have been in total chastity for 2 weeks, we will have all kinds of desserts based on slave milk."

"There they go again," said Mauricio, upon hearing the beep that preceded the ejaculation - "I'll go see how the container is doing."

30 seconds later, he returned with a look of amazement:

"It's almost completely full, it's 3/4 full, one more ejaculation and it will be full," he said with a perverse smile on his face and a sadistic gaze.

Another 30 minutes passed and the alarm began to sound, immediately Omar stopped the mach...
