No one knowing about something can feel strange. The more it goes on. Ethereal and dreamlike can become just plain weird. But it was hard to reveal something that was just for them. And so many others would be hurt by the pleasure they shared.
So they chose to keep it safe for now, although it meant there was so much they couldn’t do together. The simple normalities. A morning. Brushing teeth. Even a supermarket shop somehow held a tantalising tug of desire.
We always want what we haven’t got, they had each other, but neither liked having to share.
