Your girlfriend's younger sister is a 10-episode Candy Shorts triangle told from Mila's side, and its two free episodes get her from a private admission to a spoken one. I watched both on Premium.
A journal, a remark about the relationship and a car
Episode 1 opens in Mila's voice. She admits the thing she can't say aloud, and she says her sister trusts her with him, which is exactly the problem. Some thoughts are too dangerous to speak, so she writes them down instead.
The journal becomes a point of tension. One of them wants to read it, the other says don't, and the sparring ends in an admission that putting thoughts on paper is oddly intimate. Then he tells Mila that things with her sister have been strange and that the couple talked about opening the relationship. He adds that no line was crossed, and Mila asks why he's telling her. The episode ends on his answer: there is someone he can't stop thinking about.
Episode 2 is the confession itself. One of them begs the other not to say it aloud, since both already know. Reminders of whose boyfriend he is collide with his admission that he's crazy about her, and with a protest that they were only meant to be friends.
Someone suggests moving to the car, where it's quiet. There the exchange loops through how wrong this is and how neither of them can stop thinking about the other. The episode ends on a dare: one asks the other to say stop, and bets they won't.
Why the open-relationship remark matters
That remark is the hinge of this Candy AI setup. It gives the temptation a kind of permission, and it makes the guilt harder to shake. Mila's sister is the third corner of the triangle, present through what is said about her, and the story has to decide how much weight that permission carries.
A run of ten episodes leaves room to do that slowly. I don't describe anything past episode 2, because the confession is the part you can judge for free.
Keep the secret or close the journal: my verdict
Open the first two episodes on Candy Shorts if you're drawn to confession-driven stories, where the tension sits in what people won't say. Fast action isn't on offer here: the opening episodes are talk, a journal and a car.
Caught Between Sisters is a louder sibling triangle with a blackmail twist. My Girlfriend's Step-Sister Caught Me Staring is a five-episode cousin of this one, and My Girlfriend's Stepsister is a Spicy series on a nearby theme.
Your girlfriend's younger sister on Candy Shorts after episode 2
My explicitness score here is 4 out of 5, and it reflects the paid run. The two free episodes are confession and guilt, with no real nudity or sex scenes. My level-by-level porn scale shows what that number means.
The eight paid episodes cost 96 tokens in all, just under the 100 that Premium includes each month. The episode map on this page marks each step, and what a month of Premium covers lists the plan details.
Mila, her sister and the boyfriend
Mila is the lead, and she narrates her own secret. Her sister and the boyfriend complete the triangle. Candy AI built them as original characters, not a creator series, and they are all adults. Mila is an adult woman with a journal and a conflict.
