Jorge's penis throbbed with excitement inside Alex's ass. He could perfectly feel how a firm and elastic wall embraced him and the heat of his slave's insides radiating towards his glans. He had inserted himself completely, up to the balls. They were both lying face down on the bed, Jorge on top of Alex. The slave's body was the best support, hard, flexible, elastic; ready to rise, turn, twist with a contortion always in the service of his master's pleasure.

"Lift your ass a little, slave. Slowly."

"Yes, Master."

Jorge noticed that Alex started to raise his butt, but he not only didn't move a muscle in response, but began to press his pelvis to bury his cock even further into him. The slave, in pain, stopped the upward movement.

"Keep going up slowly, slave!"

"Aaah! Yes, Master!"

Alex increased his own agony.

"Stay there, slave!"

"Yes, Master."

Jorge was very excited, but he didn't want to climax yet. He waited a minute, and dared to slowly withdraw his penis millimeter by millimeter backwards. He was glad he hadn't used any lubricant, although Alex was secreting a kind of viscous mucus that saturated the penetration. The slave felt a painful burning when his master moved backwards because his anal sphincter hurt a lot, but he stoically endured it, and with the skills of an athlete, he maintained the position that caused him so much pain. When Jorge noticed that the penis was almost completely out, he gave a bodily thrust with all his might, trying to drill his slave in the most surprising, brutal, and painful way.

"Aaaaaaaaaaaaaaaah!" cried the slave, who immediately stifled the scream as best he could, but couldn't help but cry from pain, helplessness, and humiliation.

Jorge now withdrew his penis more quickly and repeated the thrust.

"Ammmm!"

Jorge's penis was deeply buried, hitting a wall that also caused pain to his slave. He didn't climax yet, but he searched for Alex's nipples and pinched them twisting them viciously. His slave knew he had to continue providing pleasure.

"I am your slave."

Another thrust.

"I am your slave."

Another.

"I am your slave."

Jorge couldn't hold out much longer. They rested again, with the master's penis firmly embedded inside the slave.

"Yes, you are my fucking slave. Tell me, slave, and I order you to tell the truth, did you enjoy fucking your girlfriend Sonia?"

"My Master... there is no Sonia, I don't have a girlfriend. But I do enjoy fucking women a lot."

Even Sonia was a lie. And he had almost imagined a sweet girl, blonde like him and with rosy cheeks.

"Tell me you want me to fuck you from now on, that's what you desire the most."

"I beg you to fuck me, Master, it's my greatest wish."

"Does it hurt when I fuck you, slave? Does it humiliate you?"

"Yes, Master, it hurts a lot, and...
