This is based on an idea I once had about a brother and sister who have the same taste in women and often team up so at least one (though preferably both) gets laid.
Essentially, their dad gets married and his new wife brings her daughter with her. The siblings warm up to her right away and barely get through the reception without making an overt pass at her. The siblings don't see anything inherently wrong with what they're doing though they try to keep it on low, so their dad can enjoy his honeymoon.
I figured it could go several ways with a big division being whether the kids (18 or 19) go along on the honeymoon or stay at home without any supervision and another being whether their stepsister feels the relationship is still taboo or is just inappropriate.
1. For the first time, the brother and sister start fighting each other's efforts and don't want to share or be left out. It could end with their stepsister getting fed up and convincing them to either join her in a three way or with them getting so steamed that they end up breaking their vow to never fuck each other and hate-fuck until it's out of their system
2. Stepsister realizes what they're doing early on and instead of immediately being disgusted, tries to see how far they're willing to go, either as a lark or because she has a brother sister fetish.
3. Stepsister is seduced by them and they have a tender session with the three of them deciding to make a relationship out of it. Then one day they are sat down and their parents reveal that their stepsister is actually their half-sister. Turns out the siblings dad and mom had a three way with the stepsister's mom after she had a fight with her husband. Nobody thought to check until recently.
4. Similar to 2, the stepsister sees the two of them as possible outlet for her kinks (I figured it would be funny if all of her ideas on sex came from reading erotica) and agrees to sleep with them if they indulge her. Which leads to the three of them having increasingly more wild sexcapades while keeping it a secret from their parents.
