So I had idea for a story, but I am not sure If I will ever write it so you can use it as inspiration. Please, feel free to use what you want and leave the rest.
Imagine guy being sold as clever accessory with luxurious panties. His body is augmented with high-tech (possibly nanobots) and can merge with the panties in various ways, but he can also be released to walk freely. Beside being commanded by his owner, he can also be controlled by phone app. Phone app has many functions like: put asleep, wake up, mute, read thoughts, force to crawl to vagina, force crawling to asshole, inflict agony, inflict euphoria, change mood, deprive senses and alter body shape. (I imagine him being turned into octopuss-like tongue organism at some point) He is very durable and quickly regenerates. He does not need to eat and breath but perhaps can still feel hunger for owners cum and can feel suffocating and longing for owners odors. Perhaps he may even be tasked with absorbing owners bodily waste so the owner does never need to use toilet. (Yet I would not personally enjoy explicit description of him absorbing the waste)
The story may observe his abuse and struggle for freedom and his successful escape. But as he lives on his own he starts to regret his decision to leave his owner, and he gets to life-threatening danger. He may later be grateful that his owner finds him, saves his life and still wants him, so he accepts and welcomes his role as her panties accessory.
The owner could be rich and powerful public person or some sexy celebrity (Grande, Johanson, Alba, Fox, Robbie...). The panty slave may have lived some life as normal human before being turned into panties accessory but could have his memory erased by the shady company that produces iPanties. He may later find out he offered himself to be transformed into panty slave voluntarily as he was the owners biggest fanboy. It would be cool if the owner gets iPanties as birthday present by other friends who have theirs.
