Yes, this is yet another story wherein the son turns into his mother—but with a twist! I remember reading about the possibilities of teleportation booths many years ago, in a story by Larry Niven: “Flash Crowd“. Another antecedent was the classic Star Trek episode where a transporter accident splits Captain Kirk into a pair of not-quite-identical twins. From these disparate seeds sprang one of the stranger tales I’ve ever managed to conjure up. Enjoy!
I’ve written a fair number of son-to-mother transformation tales, so I’ll just direct you to the most recent one: “No Bodyswap Here“. There are lots more in the archives; feel free to browse.
