Sampling from the Source

AJ showed up in a very good mood for her morning milking. Her mood went even higher when she saw Emily. She wore a cute little white crop top, and a pair of black leggings that stuck to her skinny legs. Mistress was bent down over her with one hand on her shoulder, whispering next to her ear.

Emily spotted AJ, and gave her a joyful but timid little wave. Mistress turned to face her, sporting a predatory grin.

“And here’s our product. Everything is ready.”

She pointed to the milking contraption with her pen, and AJ went to it without hesitation. J wore a mini skirt with nothing beneath, making her ass easily accessible. While Mistress closed the restraints, Emily walked up to AJ’s front, looking thoroughly confused.

“Good morning Emily.”

Emily looked puzzled. AJ, all tied up with straps on a weird looking chair surrounded by tubes and empty glass jars, looked as comfortable as if she was all cozy in her bed. AJ had not only grown used to the milking contraption, it just felt right. She enjoyed the feel of being a tied up cattle, **** and shown off for anyone to look at.

“Good morning AJ,” the slim girl replied. She obviously had a ton of questions running through her head, but was too timid to ask them.

“Emily!” Mistress called out. “Come here girl.”

Emily obeyed the Doctor just as easily as she had obeyed AJ and Jun the day before.

“Get on your knees.”

“On my knees?”

“Yes, right behind AJ. Get your face right in her butt.”

“Oh-Okay.”

AJ had suspicions before, but now her doubts were being cleared away. Emily would sample some prime Peach Elixir directly from the source.

AJ’s tummy gurgled. She could feel the product pushing against her sphincter, a pavlovian response to being tied up on the milking chair.

“Here’s the thing, Emily. When I said that AJ produces the Peach Elixir, I meant it literally. Her body metabolizes sugar and fat, and turns it into…” She pushed a finger in AJ’s ass, and when she pulled it out, it was covered in peach-colored juice. “... Peach Elixir.”

Emily let out the loudest gasp AJ had ever heard. Aj could only guess at what her face looked like. Horrified? Aroused? Flabbergasted? All of the above?

“She shits out Elixir?” Her voice trembled. “And that’s what you sell people!?”

“Indeed. And you’re going to help us test the product so that we can monitor if there are any day-to-day changes in its effect.”

“This is-! This is-! I- I- I don’t- It’s- Oh, oh God.”

“The effects of Peach Elixir are stronger when taken as an enema, but we haven’t finished setting up the butt-to-butt pump upgrade for the milking contraption. For today you’ll have to test it orally.”

“You want me to EAT out of her ass!?!?”

“More like drink, but yeah, that’s the spirit.”

AJ could hear Emily’s mouth gaping in shock.

“Come on, Emily, we don’t have all day.”

“You cannot be serious.”

“Put your lips around her pucker, and swallow like a good girl. Do I need to remind you of the contract you signed?”

There was a moment of silence as Emily deliberated with herself. AJ had no idea what kind of contract that girl had gotten into, but she knew how ruthless and efficient the Emporium was.

Four liters of Peach Elixir were trying to get out of AJ, so she hoped Emily wouldn’t take too long to make her decision.

“And, it’s all Peach Elixir, right?”

“Hundred percent. AJ’s butt doesn’t produce any… waste, in the traditional sense. She exclusively produces clean, sanitary Peach Elixir.”

Emily gulped down loudly, and then let out a long breath. She was obviously psyching herself up.

When Emily’s lips finally met AJ’s asshole, Mistress spanked her fat ass, causing AJ to fart out a huge load of Elixir directly in Emily’s mouth.

Mistress grabbed the brunette by the back of the head and shoved her forward, keeping her lips firmly stuck to AJ’s ass.

To her credit, once Emily had accepted her fate as a butt-juice chugger, she took it like a champ. She drank and drank, her hands grabbing AJ’s thick thighs with a terribly strong grip. Getting milked by the machine was fun, but getting milked by mouth? AJ couldn’t stop moaning and shaking her hips. With each of Emily’s gulp, AJ got one step closer to an orgasm.

Before AJ could cum, Emily reached a point when she couldn’t swallow anymore, and frantically tapped AJ’s leg, wordlessly begging for a break.

Mistress pulled her out, and in that same movement, pushed the Elixir pump against AJ’s butthole. The pump instantly took over, sucking her ass and stimulating her. The machine made her cum halfway through the milking. The orgasm caused her hole to twitch furiously, speeding up the collecting process.

AJ spent the second half of the milking in a blur, her sensitive backside constantly stimulated by the machine. When Mistress eventually unhooked and untied her, AJ just stayed put, taking a moment to rest in the milking chair.

When she got up, she first looked at the collection jars. Three point twenty-five liters. That meant Emily had swallowed nearly a liter of Elixir. AJ wondered how fast the product acted. She had her answer when she looked back and saw Emily. Or, rather, when she saw the woman Emily had become.
