I'm not much into body switching or male to female, but what about a Jekyl and Hyde story where a woman by day is a feminist crusader for women's rights but at night she turns into a misogynist man who gets off on humiliating and degrading woman, maybe with mind control powers. Will the twain meet? Details would have to be ironed out like where the male character keeps clothes and such so that the female character doesn't find it and vice versa.
Is it a potion like in Jekyll and Hyde or is it some sort of curse? I suppose it might be interesting if the feminist had latent urges she was trying to control which winds up turning her into a man. Another variant might be if the girl was was just a shy, tomboy who wanted to get rid of her boyishness and takes the potion which causes her to become a man. Then you can do the humiliation/degradation dance if that's your thing. In that situation, the fact that she already has a masculine dress sense would cover up the transformations anyway. I don't see the need for mind control but you do you.
I could imagine an all-female Jekyll and Hyde situation without any mind control. It could even be a kind of realistic setting with her having some mental illness. Innocent girl at day, slut at night. It could start with J waking up in another man's bed, asking him what happened. He laughs and replies that she didn't drink enough alcohol to have a blackout but offers her to renew her memory while removing the duvet and pulling her head down to his naked crotch. J screams, accuses him of being a rapist, takes her clothes and runs away. (Maybe even report it to the police) After a few days of similar incidents, she could ask a good (female) friend of watching her as she goes to sleep. The next morning she wakes up, finding her friend butt naked and tied spread-eagled to her bed. Her embarrassed friend tells her what happened, that she tied her to bed, forcing her to have sex all night long while being completely different. She also tells her that she didn't call herself J but H. J feels pretty bad (and her jaw hurts), so the next evening, she tries to communicate with H. She ties herself with a combo lock and leaves H a note with the request to answer. The next morning she awakes in a stall of a men's public restroom, wearing a slutty skirt and feeling sore between her legs. There is some lipstick writing on the closed door, telling her to never lock herself up again, noting some souvenir pictures on her phone. With tears in her eyes, she opens her phone and looks at the selfies, showing her in front of a sink with cum oozing from her pussy and an ogling guy in the mirror in the background. Horrified, J takes the pill after and H isn't amused as she feels horrible that night. H could film herself while getting fucked by two guys, using condoms. At the end of the clip, she tells J to make a similar vid, blackmailing her into having anal with a man of J's choice without using a condom and taking his cum in her ass or sucking him off. If she doesn't do it, H promises to repeat the threesome without condoms (every day till the end of their life). (probably such a thing already exists ^^)
or a prudish, strident feminist by day, a total submissive bisexual slut at night, and during the day, people recognize the girl as the slut from the night before. The girl wakes up each morning like everything is normal: in her own bed, in her own clothes, etc. She feels like she got a good night's sleep. Maybe one day someone shows her photos or videos of a woman who looks exactly like her acting like a total slut. Can't be her, can it?
It could work. I'd suggest a third-person perspective; you can't really "keep" that information from the player, and I tend to find "inhabiting" someone who remains ignorant to information right in front of me is a source of frustration if it isn't done with extreme care. If you went the male/female route, I'd recommend against the mind-control unless the female half has some sort of compensatory power. I think it would probably be more interesting to see a character who was "just" a manipulative sadist than one who was empowered to do whatever he wants- and tricking, seducing or coercing women into obeying him would make a more interesting contrast to his female counterpart. If you went the prude/slut route, I think I would want some sort of explanation as to how that came about, even if it's buried in one of the threads. Some sort of trauma? A villain experimenting with a drug? Hypnosis? The fact that she's getting "exposed" as something her "public" half is ashamed of seems to suggest she's being manipulated towards her downfall in some way.
Why not a feminist that doesnt turn into a man but has a split personality where she acts like one and assaults women with strap ons as a way of satisfying her repressed desires as a sadist towards other women? No mind control or transformation involved.
I think this story could totally be done without including any supernatural elements, and it would be a stronger story for it. There's no need to involve any sort of mind-control; it's just someone with "split-personality" (there is some question among psychologists about whether that's even a real thing, but who cares, this is a story). Now, if I were to contribute a thread, I would make it rather less dark than the ideas I'm seeing here; I think I would rather write a story in which the two sides of the woman find a way to cooperate with each other. Let's say the daytime personality is "Janice" and the nighttime one is "Selina" - in my thread, Janice leaves a video message for Selina asking if they can come to some understanding, and Selina responds in the same way. Most of the ideas I see here involve Selina taking charge by threatening Janice, but let's be realistic here: she's threatening herself when she does this, and if Janice gets desperate enough then two can play at that game. Janice could simply inform Selina that if she goes too far, Janice will have herself committed or even down a bottle of sleeping pills. The way I see it, they would HAVE to come to terms somehow. And because I'm into it, I'd probably make Selina a lesbian, which is especially interesting if Janice is totally straight. Many of the directions this story could go would be rather outside my comfort zone, so I wouldn't want to be the editor, but I'll contribute if it appears on the site. I think a good title would be "Night and Day."
