Growth experiment (III)

Back on the sofa, the young giant compared his huge erection with the size of white’s well-muscled torso. What would happen if he fucked the slave? He would not only tear its sorrowful ass apart, but would probably destroy most of its internal organs, and white would hardly survive. Michael decided to pospone this sacrifice, but the magnificent sensation of absolute power on his pathetic property made his erection grow even larger.

Meanwhile, black had been ordered to give a deep rimming to Michael’s ass. Really deep… The slave, poor thing, had never imagined having its neck collared by someone’s rectum, with the head well inside the bowels.  

Finally, Michael resolved that -being the slaves’  first day in his possession- he would just be jerked off by the well-developed white’s glutes and black’s pecs. After some dozen rhythmic ups-and-downs, a column of thick semen ascended violently well beyond the slaves’ heads and landed on a rug, a few feet apart.
