Bad

Lisa stomps her way up to you in a pair of 4 inch heels, and you can't help but shuffle away from her into the corner of your little cell. She stands over you with her hands behind her back, not-so-subtly hinting that she is hiding something from you. After a long awkward silence, she speaks.

"You were given an assignment the last time she was here." She nods towards your master, who is still waiting patiently at the door. "Did you complete it?"

You sigh, knowing that you have no choice but to willingly incriminate yourself. Lying would no doubt incur worse punishment. "No," You manage to say, in a smaller voice than you intended. "I did not."

She smiles and nods again "And what exactly did she ask you to do?"

"She wanted me to practice swallowing."

"Swallowing what?"

"Cum."

Her cock pulses visibly in front of you as you say the word. Your heart begins to race.

"Now why would you go and disobey your master, Slave?" Her voice is laughably innocent in its questioning,"Do you know how good you've had it so far?"

That makes you blink. It hasn't exactly been a walk in the park till now, but it could no doubt be worse. Before you can answer, she continues.

"Do you know what lesson I'm going to teach you today, Slave?"

"How to swallow?" You take an educated guess.

"Yes!" She exclaims, in mock astonishment."You will learn to swallow."

She pulls her arms from behind her back, revealing a 20oz glass bottle. You can guess what is inside, and you almost gag at the sheer thought of it.

"I can't swallow all of that!" You burst out.

"But you can! And you will learn!" She grins, unscrewing the cap. "I have an interesting method for this lesson. I guarantee it will help you swallow from now on."

She tilts the bottle and dribbles a splash of cum onto her raging hard on, then quickly uses her free hand to distribute it across the length of her shaft. You don't want to admit it, but you know what she's going to ask of you.

"Come on then," She adds, pointing to her cum-covered cock."Clean it with your mouth before I lose my patience. I know a quicker way to do this."

You don't want to know the quicker way, so you move yourself close enough to get the job done. It's unbelievable that you're being forced to do this, but you've still go your arms free. You stick your tongue out and lick the base of her shaft, where the least of the cum is. It's salty and goopy, just like the "meals" you get from the mannequins. Looking up to the bottle in her hand, you shudder, wondering how you'll ever get this done. You also notice that your instructor is getting very impatient indeed. You quickly try to rectify your stalling by diving in, licking the whole length of her shaft from base to tip. This gets you a significant amount of jizz that you struggle to swallow. After another 3 licks, you have made considerable progress cleaning her cock.

"Admirable," You are startled to see your master, now standing next to Lisa. "But far too slow. You have 10 minutes to finish this bottle, or I will make you finish it."

The two women take a step back, in order to stand side-by-side. Your master takes the bottle and slathers a generous amount of cum onto her own cock before handing it back over. Now faced with two cocks to clean, you double your resolve to take these quicker, smaller, doses to avoid shotgunning a whole bottle. Despite yourself, the second time feels worse somehow. Each mouthful is thicker, more goopy, and you are in much more of a rush. You hoped that you could turn your brain off and just go to town, but now all you can do is focus on the texture, the taste, and the amount of it building up in your gut.

After cleaning both of their cocks 3 times you look to see how much is left in the bottle. Your heart sinks as you find the bottle not even half empty. Then you notice that you have no sense of time, or how long it's taken to get this far. You begin to panic as you notice neither of the women are covering their cocks with the cum.

"Open your mouth." your master commands.

You frantically beg her to continue as she was before, but she ignores you and repeats the command. Suddenly, Lisa grabs your head and forces your jaw open while holding your nose shut. Before you can struggle, your master places the bottle in your mouth and closes your mouth around it. The thick fluid fills your mouth and you gag horribly. After a few seconds of frantic resistance, your master speaks.

"Either swallow it, or breathe it. Your choice."

The two women have an iron grip on your nose and jaw, you have no choice. In spite your gag-reflex, you begin to chug the salty thick fluid for sheer survival. You barely contain yourself to avoid swallowing it all over again, but worse. Within moments it is over, and you are released. The two women quickly leave the room without saying a word, and you are left full of cum.

After your door closes, you inadvertently burp. This causes your gag-reflex to come back full force. You rush to your now infinitely useful toilet and vomit violently. By the end of it you are spent, weak, and exhausted.

You consider following your master's orders next time.
