But not before she and Chloe had finished their lunch. The blond with the heavy udder was lowing and mooing intermittently now, overcome with the pleasure that Jenny had dialed up to 10.
"I'm definitely going to keep you," she told the blond, who had her two friends and Chloe kneeling in front of her, now. Chloe was unaffected by the changes, though the blond's two friends were rapidly transforming with each swallow of milk. Their skin had turned white with black blotches, their hands and feet had become cloven hooves, and both had long, ropey, tufted tails. Their faces had pushed out, noses large and broad with their wide muzzles beneath.
Jenny kneeled down and took the fourth teat between her fingers, crushing her face in with the other three as she wrapped her lips around it and then started suckling and drinking, herself, savoring the warm milk. She used her free hand to tap at her phone, making a few quick changes.
Where there had been four girls suckling from a cowgirl's udder, there were only two, now, Jenny and Chloe. The other two girls had stopped suckling, both of them sitting back and tilting their heads towards the ceiling as their mouths opened further and further, their lower bodies merging first into single masses of flesh, then growing darker and darker as they became leather. Their facial features receded as they started to shrink down, their torsos becoming the shanks of knee-high boots. What had been hooves, and feet before then, in their kneeling pose, quickly became thick wedge heels as their knees became the toes of the knee-high boots.

She arched her foot and toes, then slid them into the open mouth of one boot, the red pair of stockings that had been Amber gliding effortlessly into them. She did the same thing with the other girl-boot, wiggling her toes in each before standing up.
"Alright, you two. Time to go play dress-up," Jenny encouraged lazily, tugging on Chloe's leash and grabbing one of the blond cowgirl's teats to pull her along.
As they entered the costume store, Jenny looked around, snapping her fingers and causing the security gate to fall down behind them, ensuring that nobody could leave. Her first victim was a middle-aged man that clattered the floor with a hollow clang, instantly becoming a wide leather collar with a heavy bell on it. Jenny wasn't sure what to call the blond cow-girl, yet.
"Go pick that up and put it on," she commanded, releasing her teasing, milking grip on the teat, before turning her attention to the woman behind the counter. "And as for you, well, I think you'll make a lovely..."
