These might make fun stories:

Did the boy feel confused as his mother and father led him into their bed and aroused him with gentle caresses as they stripped off his clothes and moved him between his mother's splayed fat thighs, his mother clasping him tightly within her arms and legs and vagina as his father murmured words of encouragement that ended only with the boy's shattering orgasm? What did the boy feel as, the moment after his orgasm, his father began to rip his balls off with powerful hands as his mother continued to grip him between her arms and legs, masturbating against her son's thrashing body? What did the boy feel as, still immobilized by his mother after his balls had been torn out, his father's huge erection penetrated his ass and, as he bled to death from his wound, he heard his parents's moans of sexual delight at what they were doing to their son?

Did the boy want to be castrated by his father, who came into the boy's bedroom one night, and, without saying a word, or even smiling, caressed the boy's thighs and penis and testicles until the boy erupted in the most ecstatic orgasm of his life, only to hear his father's teeth click together as he bit off his son's tender balls?
