New FanFic...I don't know if this is any good.
Sebastian had never really thought his life was dull. Everyone lived the same way, until they met their soul mate, the world simply coloured in black and white and shades of grey. He remembered growing up, wondering about colours, what the sky looked like or the grass and the trees, the water in the pond on his family's property. He had asked question after question about what happened when you met the one and your world lit up, he knew that the colours faded if you weren't touching, or you spent a lot of time apart.
Sebastian spent years touching everyone, every girl he found attractive, every boy, and when he discovered sex he found that whether your partner was your soul mate or not the world bloomed with colour even if only for a moment. It wasn't difficult to find lovers, not really even at Eton he was constantly propositioned by the other boys, prefects and even house dames. He took them constantly, aching for that bloom of colour, for the sense that just for a moment he was with the person he was meant to spend his life with.
