The "bullets" were tiny electrical pulses that showed dull red in the dark.

The tiny pulses in his temple were beginning to throb again.

He felt the tiny pulses spread out and upwards through his body.

I could see the slow, steady beat of a tiny pulse in her throat.

A tiny pulse of his hips gave her a fraction more.

A tiny pulse was throbbing in the hollow where her neck emerged from the open shirt.

He watched a tiny pulse in her temple increase its speed.

One straight thrust; check just before contact, and a tiny pulse of the jets to move the two crafts together.

Yet within him a tiny pulse of warning was pounding.

I had touched it, felt the tiny pulse throbbing there, just under the skin.
