Fraternal love

My fraternal twin sister Mia and I had always loved each other very much and supported each other in good times and bad. We did everything together. I acted like her protective “big bro” (even though I was born just a few minutes before her), and she was my sweet, whimsical “lil sis” who’d always prank me to make me laugh. The love between siblings is purely platonic; we had never ever thought of each other in a sexual way.
