Because if she was supposed to be interested in him and like I said the player chose to flirt with her, the fact that he didn't want a threesome with her and Deb should be an indication, that if she really wants something to happen between them, she shouldn't go with it! It's not rocket science... And saying that she did it to entice him, after Deb dumped her, (and that's exactly what she said when she gave him the ultimatum about banging Gary too!) makes the fact that she just went with it, even after it was clear he wasn't going to be involved even more weird. Especially when she keeps repeating that she sees him in a different way. If she was just horny she should go and play with herself. If I want to show someone I'm really interested in her I'm not gonna bang someone else and rub it in her face! Again, there should be a different outcome depending on the MC's interactions with her. If the player chose to be indifferent, sure, she should go and have a gangbang if she wanted, but if the player chooses to flirt with her (and she is flirting back, so it's not one sided) banging his sister makes zero sense and just makes her character look cheap.
I'm not gonna bother answering to anything else, since you seem very fond of assuming things about people you don't know and think that your way of viewing things is the only right way, while funny enough accusing them of doing the exact same thing. Have a good day.
