"Miss Davis informs me that she does not think your bowel movements are regular enough, Miller," Miss Dawson stated, smiling broadly as she gathered some equipment together noisily.
"But I go every day, Miss Dawson," Hannah muttered, face reddening at having such a private matter discussed.
"So you are saying that I am lying, are you, Miller?" hissed Davis and Hannah squealed as the heavy leather strap whipped down across her arse cheeks several times.
"No, no, of course not, Miss Davis," Hannah hurriedly replied but the strap kept on lashing her bare bottom for another few seconds, driving bitter pain deep into her flesh.
"I am glad to hear it, Miller. Now stay in position for the doctor to administer some treatment to you."
Hannah wondered what was happening as hands pulled her smarting arse cheeks wide apart and then came a dollop of something cold slithering down her anal crack before a finger rubbed it into her dark hole. Hannah jerked a little as something began to slide inside her bottom, squirming further and further up as she hung her head in shame. Miss Dawson pushed the rubber tube deeper, making sure that it was snugly ensconced before she stood and connected the other end to a large glass bottle that was resting on a metal stand. A twist of the tap at the bottom of the glass vessel and then she watched in amusement as cold water started to slither down the tube and into Hannah's bottom.
"How much is in there then?" inquired Davis, tapping the bottle with her fingers.
"Nearly a gallon but she'll explode if we give her all of it!"
Hannah felt coldness creep into her bowels as the tube dripped water steadily into her darkness. The sensation was strange and became more and more uncomfortable as the seconds ticked slowly by and more water forced her stomach to swell. She began to moan softly as the pressure intensified but Davis knelt down by her side and snapped at her to control herself, threatening to whip her breasts and thighs if she expelled any of the liquid without permission.
"In fact," added the guard, "you can make yourself useful by licking my pussy until I come and then I might think about getting the doctor to turn the tap off...unless she wants your tongue as well?"
"That sounds like a good idea, Miss Davis," murmured the doctor, watching with interest as the guard slid under Hannah's head and lifted her skirt up to reveal her pale thighs.
Hannah eagerly licked away at the scented slit in between, keen to make the guard orgasm so that she could escape from the dripping torment of the water filling her bottom up. She tongued the puffy folds then eased the tip onto Davis' clit and teased it gently. She licked along the length then fastened her lips onto the tiny bud, sucking it hard and making it swell in response. Little groans and hisses seeped out of the guard's lips as her clit was teased and tantalised constantly. Arousal spread swiftly up through her flesh until she cried out, thighs shivering with desire as rapture flooded into her body.
Miss Dawson replaced Davis a few seconds later and Hannah sucked on the pink folds of flesh, lapping away afterwards at the slickness even as she squeezed her buttocks together tightly to prevent any seepage. Davis noticed and turned the tap on the glass jar further open, making the liquid slither faster into the prisoner's anus. Hannah groaned into the moistness in front of her and redoubled her efforts, licking fervently around the tiny bud and feeling the doctor begin to respond. Warmth bathed her face along with the woman's intimate scent as she tongued the nub desperately, knowing that she could not hold on for much longer without disgracing herself. Dawson started to sigh and then moan before wave after wave of pleasure shook her body whilst a rush of sweet love juice soaked Hannah's face. She licked it up eagerly then concentrated on squeezing her bottom cheeks together as hard as she could as the doctor slowly rolled out from under her and went to turn off the tap.
"That's most of that gallon gone, I see," Miss Dawson stated, raising one eyebrow as she realised that Davis had fiddled with the tap. "Better let her get on the bucket quickly or there will be a hell of a mess to clear up!"
"Shift yourself, Miller. Squat over the bucket but don't let go until I tell you!" ordered the guard as soon as Miss Dawson had pulled the rubber tube out of Hannah's anal hole. Hannah moved as quickly as she could, cradling her bulging stomach in one hand as if she was pregnant. Her buttocks touched the cold rim of the metal pail and she waited, body quivering with the effort of holding the water inside and then, relief merged with shame, as Miss Davis finally told her that she could go. Instantly, Hannah relaxed her muscles and began to cry as the water flooded out of her in a great torrent, cascading down into the bucket noisily. Some splashed up with the force it had been evacuated with and struck her bottom cheeks but most gushed out and settled in the bottom of the pail, swilling around as more was added. It felt like a never-ending stream was pouring out of her bowels to Hannah and tears trickled down her cheeks as the doctor and guard observed her with interest.
"I wonder how much more she could hold?" mused Miss Dawson thoughtfully.
"Perhaps we should try both holes next time? A tube into each one and see how she likes that," responded Davis with a sly smile spreading slowly across her face as she saw Hannah look up in shock at the thought.
"An excellent idea although I think that she has had enough for now. You better return her to her dormitory because we don't want her getting damaged before Friday's entertainment, do we? Miss Stern would not approve!"
