Just use lots of euphemism. Like, in a draft of my work - I was like: "The car was parked forwards as a testament to last night when he was in a rush to get home to a needy wife, who had required him urgently for a certain matter. It seems she had lost something, and that is an observation I make by recursion - as that night, they lost some sense of tradition (after all, the car was always parked backwards - except this once), they lost their inhibitions... and their clothes. And they lost the opportunity to watch something on TV (not that big a loss, they recorded it anyway), to opt for more... carnal and fundamental behaviours that night."
I really liked that scene. Because it said nothing. But it said everything.
Teacher didn't like it, I took it out... regrettably.
