Samantha's paws were very feline in shape, but retained just enough human characteristics to still function like hands, if barely. Tricia let out a moo as Samantha started to milk Tricia, tugging and squeezing at the thick nipple until milk started to form, then began to squirt out.
"Oops -- let me make a bucket," Samantha said. A few presses on the remote, and she had a bucket ready to take the milk rather than having it spray all over the floor. She set the bucket by Tricia.
Tricia hesitated, but only for a moment before she bent over onto all fours, positioning her breasts, which now hung down heavily from her changed torso, over the bucket. The pressure she felt was definitely from needing to be milked, and she mooed again as Samantha resumed the process. Tricia knew she ought to feel embarrassed, being milked down on all fours like a cow, and she was definitely weirded out by the other changes done to her, but the feeling of relief she got from being milked was confusing her. It just felt good and relieved a need she had never known before -- she certainly did not want it to stop before she was drained.
It did not take long before Tricia was completely milked -- for which she was not sure if she was glad or faintly disappointed, or even both.
"So, how do you feel about that aspect of your body, or being a cow?" Samantha asked, pulling the bucket out from under Tricia. "Mmm... wow. This smells good." Samantha's nose twitched. Her tail lashed a moment, then she got down on all fours as well, and lowered her feline-touched head down to the bucket to begin to lap up the milk, purring like a cat.
