"Alright I'll do it this once, just to help you out." Mary walked over to the couch and sat down. She spread out her legs to make room for her swollen udder. Jess knelt on the ground in front of her and after making sure her own udder was comfortable she got ready to milk her friend. "Thanks soooo mmmmuch." said mary with a slight cowish lisp. "Whatever," replied Jess, "lets just get this over with."
She grabbed on of her friends leaking teats and stuck it in her mouth and began to suck. "That's perfect!" moaned mary in relief. She could feel the preasure begin to decrease from her udder and she leaned back against the couch.
As for Jess, she couldn't explain it but she had never tasted anything so wonderful in her entire life. She began to suck faster and faster on the teat. Soon that teat was empty and she hurried to the next one. "Yoooou don't seemmm to be commmplaining any mmmore." joked mary, "In fact it looks like yooour enjoying it as mmmmuch as I ammmm." Mary was indeed enjoying it. It felt like the satisfaction of urinating after holding it for hours, but greatly magnified. Jess merely glanced up at her friend, with milk dribbling down her face, as she focused on drinking the fabulous milk.
After a long time mary could tell that her udder had finally been emptied and she told Jess she could stop. But Jess was addicted and she kept sucking at mary's dry teats hoping to find something. "Alright you can stop it now Jess. Stop it!" and mary pushed away her friend with a hoof-hand. Jess fell back onto her tail with her udder sloshing between her legs.
"What has gotten intooo yooou Jess?"
"I don't know but I think the vials affected my taste too because your milk tasted amazing!"
"Well snap out of it! Yooour freaking me out."
"I'm sorry." but Jess still gazed longingly at mary's udder.
"Well, what now?"
