Gece vardiyası nastiness

Two blonde prison guards sit and complain to each other about the terribly boring graveyard shift they have to work tonight until they decide to use the two pitiful prisoners in a cell behind them for their own entertainment and sadistic pleasure. The jailbirds are strapped very, very hard on their bums and the back of their thighs, while the women laugh like witches on an evil mission in the night. They next move on to the men's nipples, pinching them excruciatingly hard, twisting them and pulling hair from around them. The women finally feel satisfied after chasing the prisoners around the A-frame. They pinch them, grab at them, and hurt them when they can... the men scurry around like petrified, hysterically giggling mice.
