The Urielites shifted nervously. They were a young class of relievers and newly-Fledged or created, about to be sent to Earth for the very first time. They'd taken many classes, but of all, this promised to be the strangest, Laurence thought, toying nervously with his hair. Human sexuality.

/Why do we need to learn about that, anyway?/ Laurence thought. /We're not human./

Of coure, he'd been in several other 'human-something' courses - Human Warfare, for example, or Human Armaments, or Human Morals. But this *sexuality* - the word sent an uncomfortable shiver down his spine to settle awkwardly in his stomach - was something he was half afraid of.

"All right," the grizzled old Cherub teaching the class began, "Who here knows the basics of human sexuality?"

A hand shot up from one of the Mercurians. The Cherub pointed at him and scowled. "YOU! Unpure! Go report to the Clensing Room for purification!"

The Mercurian lowered his hand. "...Yessir."

They all watched him trudge out.

"All right," the Cherub said, grimly. "Now to learn about the most *forbidden* acts - though I dare not say too much, for risk of corrupting your young minds."

Laurence gulped. This was clearly going to be a LONG class.
