A couple of very Ballardian passages from The Moviegoer, which came out eight years before The Atrocity Exhibition:

After a car crash:

The traffic has slowed, to feast their eyes on us. A Negro sprinkling a steep lawn under a summer house puts his hose down altogether and stands gaping. By virtue of our misfortune we have become a thing to look at and witnesses gaze at us with heavy-lidded almost seductive expressions. But almost at once they are past and those who follow see nothing untoward. The Negro picks up his hose. We are restored to the anonymity of our little car-space.

A married couple who have written a sex manual:

It is impossible not to imagine them at their researches, as solemn as a pair of brontosauruses, their heavy old freckled limbs twined about each other, hands probing skillfully for sensitive zones, pigmented areolas, out-of-the-way mucous glands, dormant vascular nexuses.

And a bit that made me laugh:

As for Sharon: she finds nothing amiss in sitting in the little bucket seat with her knees doubled up in the sunshine, dress tucked under. An amber droplet of Coca-Cola meanders along her thigh, touches a blond hair, distributes itself around the tiny fossa.

"Aaauugh," I groan aloud.

"What's the matter?"

"It is a stitch in the side." It is a sword in the heart.
