Sister Swap by Tgsquirtle

 

Fan cover made by Clavietika

Following the example of the main game, some authors started creating some scenarios with several stories and lore, and Sister Swap had big ambitions for what its story was going to be.

Based on the scenario thread, Sister Swap was one of the first scenarios to ever be made after Stuck and even had a general outline and even a big twist planned before the author dropped it completely.

There are several routes in this scenario raging a variety of concepts, not just a Sister Swap, which is only the event that starts things out. In this world, the protagonist is Riley and the swap starts with his sister Allison in a discussion Riley started while being picked up by his sister, it's easier being a girl.

Turns out that Riley comes from a family of mages that can change reality and saying "I wish" out loud triggered the first manifestation of his powers, a body swap with his sister.

The summary of the routes goes more or less like this:

-In one of the routes, Riley goes to his house neighbor Marty and due to their sexual desires they end up having sex, Marty and Riley (in Allison's body) swap again due to Riley's still unconscious powers, and they have to act like they other while they figure out what is happening.

In another route, is Allison (in Riley's body) that ends up having sex with her friend Cassie due to their own sexual desires, after that, Cassie and Allison go back to Riley's house and ask Riley to swap them so Cassie can fuck herself, they believe Riley has he power since when they try to swap between themselves, it does not work, Riley accepts with the condition of borrowing Allison's body for a little longer, Allison accepts saying that she wouldn't mind having Riley's body permanently.

In another route (ditto), Riley (in Allison's body) asks Yuuna, one of her Mom's friends to swap with him out of curiosity, Riley goes to her home and has sex with her husband Greg, the next day after waking up in her bed Riley goes back to his home to ask Yuuna to swap back, Yuuna doesn't remember anything, neither Allison in his body, he tries saying I wish out loud, it doesn't work, what happened? According to Tgsquirtle, what was planned for the route was revealing that Riley liked Yuuna's life so much that he unconsciously wished to stay as her and he affected the memories of other people as nothing had happened.

This is one of the first interesting ideas the scenario shows, an interesting approach in Reality Change based on a subconscious wish.

Another swap that happens is Riley (In Allison's body) swapping with his mom out of curiosity, her mother tells him about his power and she accepts, afterwards, her little sister, Olivia, asks her to get bathed together since she's used to it since she is still a kid, Riley first refuses but due to his sister's cries he accepts and does her hair showing the first glances of maternal instincts.

The last route shows Olivia growing up to an adult by accident due to Riley's words and ends up in Olivia morphing her mother into a kid while trying to trade places of mother and daughter so she doesn't have to be told to go to bed or being bossed around by her again, Olivia seems to have the same powers as Riley and be simply saying it, she can morph people, control their actions, and also their memories, this plants an interesting villain that has basically the mind of a child but also unlimited power. Unfortunately, morphs done in this route violates the TFGS rules due to the depiction of minors in sexual situations, which led to ST developers removing it. The option for the author to rerelease the scenario edited is still there, or even continuing it, but according to Tgsquirtle the project is now completely dead.

The main plot also depicts Yoshinori as a wise grandfather that Riley calls in for help, Yoshinori teaches him about how he will be able to control time and space in the future and how he will teach him to control his powers, he uses magic to make one of Riley's Mom's friends go into a vacation and he morphs into her so he can take care of the family in secret due to issues that happened with her mother.

All the routes end up there until I explained them, the scenario is no more than 30 minutes long so far, but Tgsquirtle mentioned a whole outline they had for the story in which (spoilers) it's explained that Riley's dad is actually Olivia, morphed by his brother, Riley's uncle, in undefined events, apparently, Riley's uncle had the same abilities as his father and developed a God complex, even then, his whereabouts were unknown in the final state of the scenario.

Riley's dad, Claus, lost all his memories and he would be able to recover them only as an adult, once he grows up as Olivia, making his own wife take care of after him.

Tgsquirtle mentioned being reading a lot of fictionmania stories at the time which inspired the routes in the scenario, even the story "where someone gets turned into a baby and loses their memories until they reach adulthood". 

In general, the execution of all these concepts was no better than your average TF doujin, characters act rapidly, nonsensically, thinking only about sex, the animation was very limited and poor, with static characters across the screen even in sex scenes, but bringing up all those TF concepts and ideas into a visual novel narrative was an interesting idea that was getting known at the time thanks to PS and ST, the whole family magic and lore of the scenario was vivid and interesting. Overall, even when not playable anymore, this scenario shows an important step for the ST community and TF in general.
