The important thing was that they never kissed.
That was Rei’s boundary. She could handle it when Minako flicked her tongue in her inner ear and pretended she was telling secrets. She could handle it when Minako sank her teeth into Rei’s pale flesh and left marks that had to be explained by flying sparks and heavy concealer. She could handle it when they would be out with the girls and suddenly Minako’s hand was stroking her inner thigh while she gossiped about the cute waiter with Makoto. She could handle it when Minako followed her into the bathroom, pushed her into a stall, and covered Rei’s mouth with her hand to silence the cries that followed.
But Rei couldn’t bear the thought of ever kissing Minako. That would mean that she felt something, and even if Minako wasn’t a boy, Rei couldn’t bear the thought of being in love.
