I had grown used to the dynamic between my stepmother and my father since my mother had moved on when I was 16. My dad's slave-status meant that he could not simply be divorced, but instead had to be sold, and my mother had carefully picked a new owner for him through a series of interviews and even some psychological tests. I'd attended his collaring ceremony - it was a clothed event - but not the more private ceremonies they'd had to celebrate afterwards.
My mother explained that I had reached the age where I'd soon need a new kind of female guidance, and that she wasn't best placed to give it. She had left me in the care of a 32-year-old woman named Sofia, whose house rules meant my father and I only wore tight shorts around the apartment where we lived, in one of the 'family' zones of our planet-spanning nation. That meant it was somewhere that sex happened only in private, and public nudity, while allowed, could not include a wide range of things considered sex acts.
That was fine, as things went. I continued my studies, and while Sofia encouraged me to meet girls and boys my own age and explore things with them, I made little progress with that side of life. She told me to take things at my own pace, and confidently predicted that when I turned 18, things would be very different, and much better, for me. At her urging, I took one of those personality tests with full body scanning, and it told me my fetish quotient scores, but I decided not to let anyone else know them for the time being.
The first big change that happened when I turned 18 was that Sofia moved us immediately to an adults-only area of the planet. When we got to our new apartment, while the drones unpacked our crates, Sofia took me and my dad into the main bedroom, and I sat down on the bed there, while she and my father stood.
Sofia clicked her fingers and my dad pulled down his shorts to expose a chastity cage and a shock ring that nestled around his balls. Sofia pointed to the floor and he knelt, then she took out his wedding collar, the one he had only worn with her in private since their wedding, and locked it around his neck. He kissed her feet reverently.
"James, your father and I plan to live like this, all the time, now - he won't be wearing clothes anymore now you're 18, and I'll be much more open in the way I treat him as my property. You know, of course, that your father is legally my property, yes?" said Sofia.
I took a few moments to get over the shock of seeing my father act that way - he had always taken Sofia's lead and done what she'd said, but here in front of me was a man acting as a slave rather than as a sub-husband, and that was somehow different. Nonetheless, I accepted them for who they were - that was, after all, the guiding principle of our whole culture.
"I know that, Sofia, sure - I've known that since you had your wedding ceremony, and we talked about it a lot when my mum sold him to you and I came under your care. It's great that you two can live the way you want - though there are limits on what I want to see," I replied.
"Everything we do is completely natural and normal, but we hear you," said my dad.
"Are you going to start dating anyone now you're in an adults area? You could upload your fetish quotients to the net and an AI could match you up with someone - it would be so good for you," said Sofia.
"I dunno..." I said, then trailed off.
"No?"
"No."
"Well, plenty of time for that."
"Is that all?" I asked.
"No, James, not quite," said Sofia, "you know I run a female-led household and you've told me before that you're perfectly happy with me being in charge - you have your father's submissive genetics, as I'm certain you're aware."
"Yes..." I said, with a sinking feeling.
"I won't have a clothed male in my household, James, now you're 18."
"Right. But-"
"No ifs, no buts, take your shorts off and give them to me please."
"I don't know, Sofia, it's a bit much for me."
"It's perfectly natural for you to be naked in front of your superiors. Strip, immediately, please."
I knew it was natural but I could feel a hardon coming at the thought of being naked in front of a beautiful woman. Sofia smiled and nodded and made a motion at me: stand up and get them off. I thought quickly about my options: I could walk out of the apartment and submit a request for re-housing, but given I had always accepted Sofia as head of household, and given that the AI would want a good reason, I wasn't likely to get it. That meant I'd either have to walk the streets, go to some kind of hostel, or strip.
"You know, James, it's totally normal to be aroused by Sofia - she's not your mother, and as head of household she has a position of power that men like us respond naturally to. I can see you're getting hard, and that's OK - just take them off," said my dad.
With an enormous blush spreading across my face, I got up off the bed and put my fingers through my underwear. Sofia nodded and smiled, my father did the same, and I pulled down my shorts and stepped out of them. A semi-erection bounced around, and I was acutely conscious that my well-kept pubic hair was in stark contrast to my dad's smooth cock and balls. Sofia tossed my shorts into the recycler.
"Do you acknowledge me as head of household honey?" she asked me.
"I do," I replied evenly.
"Say it fully please."
"Sofia, I acknowledge you as head of household."
"That's great - give me your left wrist a moment please. OK, this just snaps on like this, and now you're tagged - the house sensors won't let you leave unless I authorise it, and I can track your location wherever you go, and call you on this if I need to. It's a big change entering the adults-only zones for the first time, and this just lets me know where you are and what you're doing. Now, why don't you go finish unpacking - but I want you to unpack your clothes into the lockable wardrobe next to the door. Good boy, off you go."
*****
Life settled into a rhythm of normality for a few days. I was allowed to leave the house a lot, and I went on a lot of long walks while Sofia and my dad played together in the apartment. I made some friends through a matching service, boys and girls, and we hung out together (I was clothed, they were mostly not).
As a few weeks passed, I got used to Sofia seeing me naked all the time, and my erections began to subside. She commented disapprovingly on my pubes, telling me that genetically submissive men like me usually shaved them off, and I'd be sending out mixed signals to anyone I met by having any kind of bush there, and would I consider getting rid of them?
My new friends agreed when I asked them - they were surprised I had pubes at all, as all the subs in the group were bare - and after I thought about it for a day I decided to try it. I went to Sofia and told her, and she hugged me tight then got straight on the net and booked us an appointment at a sub-salon for the same day.
When we arrived, I was ushered into a little white-tiled treatment room, windowless and private, with a calming spicy scent in the air. We were attended by a slavegirl in her twenties, nude except for a utility belt and a pair of slippers, and she took me by one arm while Sofia took me by another. Together they pushed me firmly into a metal frame that projected out from one wall, and when the frame's sensors found my hands, metal bars unfolded and then locked cuffs around my wrists.
"Frame: secure fully," said the slavegirl.
I yelped as the frame pulled me by the wrist back towards the wall. More metal arms unfolded and my ankles were shackled in place too, then a linking arm emerged and the ankle shackles were connected together. Another metal strap uncoiled around my waist, then a collar shot out and clamped itself around my neck; for completion, one more strap bound me beneath the shoulders, and two more cuffs attached themselves to my upper arms.
"Just one moment, my feed needs a new before pictures of him like this for my girlfriends to see," said Sofia.
"Sure thing, miss," said the slavegirl, and stood back.
Sofia snapped a few pictures of me from different angles, including some closeups of my cock and balls, and she reviewed them with a critical eye, then took a few more. I saw her holo display, and I cringed as I watched her upload them into her feed, and the reacts came in suspiciously fast, almost as if she had forewarned people to watch out for them.
"Ready, miss?" said the cute sub girl.
"I'm almost ready, slavegirl," replied Sofia, "but first, show me your pussy up close - I'll just bend down. So smooth, so bare! Tell me, do you have to have it treated often to keep it like that?"
"Thank you, miss. My owner-wife has had me permanently depilated - it's done through a combination of laser treatments and chemical application, with a final layer of self-renewing nanotech that penetrates the skin and prevents the formation of new follicles."
"Oh - how marvellous - and what a shame I only booked him in for temporary removal..."
"Let me just query the system, miss - one moment please - hmmm, it looks like we're not fully booked, so if we move my next appointment to someone else, I can spend the extra time with your property here and we can get him properly bare forever. It's your choice, miss."
"Good girl - do it."
"Please, Sofia-" I said.
