Ever since I came out of the closet, for whatever reason, my mother has been more open with walking around the house in various states undress. Perhaps it was just because my mom had always wanted a daughter, one that would be able to inherit her innate power, since my mother's type of magic would lie dormant in males and only awaken in females. Though, despite her seeming slightly worried for a second the first time I told her, it seemed she finally felt more of a kinship with me when she discovered that we played for the same team to an extent, having at least that similarity. So we could at least talk about guys, if not magic. But, ever since I turned 18 and came out to my mom, I noticed she began caring very little about being properly dressed while I was around. I guess part of it might also have been that she didn't want her son to be getting inappropriate and lustful thoughts about her, so she stayed modestly dressed most of the time.
I mean, she is an objectively beautiful woman, with long brunette hair, rather large breasts, fairly tan skin, blue eyes, and a warm smile. I knew growing up that plenty of guys had a crush on my mom, but I never returned the favor with their mothers, since I just never was interested in girls like that. I bet some of those guys would have killed to be in my position, though. Some days, I'd come downstairs in the morning to see her making coffee completely naked. She'd get dressed later when it was time for her to go to work, but sometimes, on her days off, she'd stay naked all day. So, since my mom was enjoying the freedom, I just thought it would be alright if I did the same. And luckily, when she saw me come down the stairs one morning completely naked, she didn't mind at all, giving me her usual smile as she finished making the coffee.
With our small household basically becoming basically nudist, it just seemed like the a rather unnatural, yet nature step forward when my mother came home from work announcing a new spell from work that she was going to help test. A few months before my 19th birthday, I had just came home from a camping weekend with my boyfriend and his family (the two of us had intended on getting intimate for the first time, but due to his family's crazy schedule, we never got the chance), when my mother began explaining what she had done to the house. See, my mother... well, she knows magic. My mother came from a very long line of witches, who used magic outside the public's eye for their own goals. And as her job, while my mother claimed that she worked in an office building, even intentionally living in a very common house as to not arouse suspicion, my mother's truly well paying job revolved around using her magic to forward her group's research into the arcane, inventing new spells and other practical applications of their magical power. So, when I got home, she was waiting for me, actually modestly dressed in a her work clothes.
She sat me down on the couch and explained the situation to me. Basically, every single surface in the house was now enchanted with a new type of magic. The way she explained it, this type of spell would lie dormant, only coming active when human bodily fluids or waste came in contact with it. It would then glow slightly, then cause that fluid or waste to absorb into whatever surface it was touching, taking every trace of it's existence away. My mother had already gone to the lengths of enchanting the whole house with it, including the walls, the tables and chairs, this couch and the floors, both of our beds, and even the electronics for some reason. She also added that she would be testing the spell's longevity and durability and I was welcome to do the same. She also added that it seemed to work, since she had wet her bed that morning and it was completely dry seconds after she had finished going. And, even though she only mentioned testing pee, she assured me that it would work with poop as well. She figured that, since we both hang around naked and don't make a big deal out of it, seeing each other relieving ourselves wouldn't be that much of a step up, so I was free to go as I pleased. She then got up and kissed me on the cheek, then headed off to work, saying that while she's gone, I could get used to using the enchanted objects, but I could still go in the toilets if I wished. I was under no obligation to test the spell, but my mother would be using it openly.
