"Bend and spread"

A slave isn't allowed to feel modesty or shame!

Slaves aren't allowed the luxury of feeling emotions such as shame or humiliation. If, in fact, if they do have these feelings, they soon learn to suppress them, or at the very least, to keep them hidden from their masters..

Of course, they are kept slave naked - they are after all just another domesticated animal - and their naked bodies are open to scrutiny at all times. And they are subject to "close quarter" examinations - colloquially called fingerings - when no parts of their bodies are exempt from hands-on inspections even of the most invasive type.

In time, a slave becomes immune to being fingered and will pose his body in the positions demanded of him. He'll flex his muscles and stress his body to highlight his physique and he'll even suggestively stroke his cock to erection and, if ordered, he will masturbate.

However, there is one display position that is universally hated by all slaves and they dread the command to "bend and spread" to display their arse-holes for public scrutiny. Whenever, a slave is being fingered, he inevitably knows that order will be given to him and any hesitation or defiance on his part will result in a whipping.

Therefore, he immediately shuffles his feet apart, bends at the waist and reaches behind to spread his buttocks as far apart as is anatomically possible. As he waits to be violated by an intrusive finger, he burns crimson with shame but nevertheless, he cooperates by wriggling his arse backwards to make it more accessible. 

Then he waits as a finger teases the puckering, tender flesh of his anus before forcing itself through his tight sphincter to probe the depths of the most intimate and innermost recesses of his body. 

As the heading to this post states - a slave isn't allowed to feel modesty or shame. That is a lesson all slaves learn very quickly!
