This is basically a deconstruction of NTR. Instead of being a chad who's a god of sex and can rule everything in the world through the power of his Infinity +1 God Cock, he's a pathetic nobody who becomes entrapped by it and can't get out.
Cliched perhaps but IMHO accurate comment: "The story you have just read or are about to read is true ... the names have been changed to protect the innocent."
