>>30835881Think of it like this. Lillie and Sun love each other very much. They love each other, and want to be with each other. But what happens when they've loved each other to the max amount, where there love can no longer go higher? Say, they've reached the level cap?
They have a baby. They share their love with someone who they've created. And to make babies, you need to have sex. So in the end, sex is inevitable. If you can't avoid it, embrace it, and it'll feel good. Everyone likes feeling good.
