Women's Prison - Sara's training (second part) (Pixiv Fanbox)

Sara is an argumentative prisoner, so the guards have decided she needs to learn how to keep her mouth shut. Having filled up Sara's mouth (in the previous part), the guards place her in the standing cell where she will remain overnight. Dialogue: Remember, we want to see your mouth still full when we get back. Otherwise, you'll have to try again tomorrow night. Before closing the lid, one of the guards gives Sara some extra encouragement.
