"Now I'm asking for a volunteer for the last show!" announced the world-famous magician.
Eleven-year-old Michael jumped up from his chair and raised his hand. His father, sitting next to him, tried to pull him back, but the boy was too eager.
The magician's eyes scanned the audience, then held out his hand.
"The boy in the blue shirt in the fifth row! Please come on stage!" he told.
Michael couldn't believe how lucky he was. He grabbed his father's hand and pulled him up to the podium.
"Hello! What's your name?" asked the magician.
"Michael"
"Well, Michael… Do you know that a painful death awaits you?
"Yes!"
"A kind, brave and very enthusiastic boy! Won't you miss him?" the magician asked the father.
"He will be missed, but his greatest wish was to stand here on the stage. I can't do anything about it."
"Then let's not waste time! Ladies and gentlemen! Among the botched magic tricks are…. Table of Death!"
Michael's heart skipped a beat as the helpers pushed the device onto the stage. The boy's body was covered in cold sweat and he was briefly seized with fear. But the fear quickly gave way to some strange excitement. He felt a tingle in his groin and his penis began to harden.
"Do you have a last wish?" asked the magician.
The boy thought, then answered:
"I would like dad to undress me and help tie me down to the table!"
"As you wish!"
The boy raised his arms. His father stepped behind him and took off his shirt. Micheal sighed as he felt the cool air on his hard nipples. He unbuttoned his pants and let his father pull them down to his ankles. His erect penis lifted his underpants. His father also pulled it off and the thin young cock sprang up.
The audience gasped at the sight of the exposed and excited virgin body. The father stood proudly behind him and reached forward to caress his son's nipples.
"Aaahhh" moaned the boy and blushed.
He closed his eyes and leaned back against his father, enjoying the sensual feeling he had never experienced before. But it was time to move on.
Michael took a big swallow and voluntarily went to his doom. He walked over to the device and stopped in front of it. He eyed the wickedly glistening spikes that would pierce his skinny body. There was no doubt that it would hurt a lot, but his death throes might be short. The magician sensed his hesitation. He stroked the boy's bare back encouragingly.
"We can blindfold you if that makes you feel better!"
"I do not need it." Michael replied.
He quickly sat down on the table and lay on his back. His penis was pointing straight up. The magician cuffed his ankles. His father chained his arms to the table. Michael looked up at him.
"Promise that you won't look away, no matter how bloody it gets!" asked the boy.
"I promise!" answered the man sadly.
"I love you dad! Can I have a kiss goodbye?"
The man leaned down and kissed his son's forehead.
"Not like that! A real french kiss!"
The father was surprised at the request. If he had known earlier that the boy had such desires, he certainly would not have allowed him on stage. It would have been a wonderful feeling to penetrate his tight ass or enjoy his mouth. But it was too late for that. Their mouths stuck together and their tongues intertwined in front of everyone. Sighs were heard from the audience. Then the father stepped back. The magician performed the usual show and then lit the rope holding the spikes. "Oh my God! I'm so scared!" - thought Michael. He involuntarily tried to free himself. His struggling body was a sexy sight but he quickly got over his weakness. He forced his body to relax. He threw his head back and looked for the gaze of his father standing behind him. He calmed down a bit when he saw that he was looking at him, true to his promise.
The rope broke and the spikes began to fall.
