My sister wants to fuck ngl but feels like sibling love > lust

NY(O) <br><br>TL;DR: Sister says she wants to do it but is afraid it will change how we look at each other<br><br>We are both like 15 (she is the younger one) and have been the best ngl the past year (we weren't close when we were younger, joined a new family). We joined our family at the same time and share a room (it's not an issue as we sleep in our own bedrooms and I work from home). She ngl is the sexiest young girl I've ever seen tbh (I am a bit of a perv so apologies in advance) and for some reason, I think she feels the same about me. <br><br>This morning, as I was brushing my teeth with her in the bathroom I asked her why she never lets me see her naked and right as we were both almost naked, she said "I don't know, I just feel weird" and as I was like "me too" she said "fuck it" and took off all her clothes. A tad embarrassing ngl but I did the same and we both looked at each other and I asked her if we both looked ok. Uncomfortably, she said "yes, please stop looking ngl" and that was that. <br><br>Later in the day, we had a shower together and that was nice, we didn't even look at each other. However, at dinner she came up to me and said "I am actually really sorry for making you look at me. It was embarrassing" and that made me sad a bit but I said "it was nice" and she said "I just don't want us to make love or be a couple. I feel like that would change everything" and I was a bit annoyed but also happy. <br><br>Then I said "I also feel like that, I don't want to be a couple, I love you as my sister". She said "I also don't want to be a couple, that's why I do not want to be intimate with you. I just want to keep things as they are, I feel like they make love with love, it's what makes it special" and that kind of made me sad and also happy.<br><br>In the end, she said "I also don't want to be a couple, that's why I do not want to be intimate with you. I just want to keep things as they are, I feel like they make love with love, it's what makes it special" which I kind of agree with.
