After its feeding, the guard took the dildo, and ordered 143 to stand and grab his own ankles. Then the shoved the dildo up 143's ass.
"Release your ankles and stand up. There you go, keep it in there during exercise period. We don't want you having any accidents, do we?"
143 wasn't sure what the guard meant by accidents, but he didn't like it. He walked awkwardly over to the door that the other prisoners were filing out of into some sort of daylight. A courtyard or fenced area maybe? The dildo kept trying to work its way out, 143 clenched his muscles to keep it in place. It felt weird because it raise the butt flap on his loincloth to expose his bare ass cheeks. As he entered the blinding light of the "yard", another prisoner bumped into him and whispered, "Boss? That you? Don't worry, we'll get you out."
"Keep walking 143!" ordered a guard in the yard shoving 143 forward by pushing his dildo with his nightstick.
