Emily makes the decision to leave her parents unaware of Kelly's new form.
"I'm sorry Kelly. I hate to just leave you here with the rest of the cattle, but I think you'll be okay. You seem happy with it" Emily informed her, ignoring the warm feeling that washed over her for a split second.
Kelly stood up on her hind legs and pulled Emily in towards her, and gave her a big lick across the face.
"Eww gross Kel!" Emily squirmed. It actually felt kind of nice though. She could feel Kelly's breasts pushing into the bottom of her head, and realised they were making her damp. She glanced down and they were leaking milk onto her baggy jumper.
Surprisingly, that didn't gross Emily out though. She actually kind of... wanted to taste it. '...Milk? That actually sounds kind of good right now...but no that would be weird. I can't drink from my cow sisters boob!'. A tingling sensation formed in her own breasts, almost as if they were urging her to do it, but she resisted.
Kelly seemed to have other ideas though, and shoved it right into Emily's face. She instinctively latched on, and started drinking from it. Kelly mooed happily.
'What the fuck am I doing?! This is weird. This is SO weird. But it also...tastes so good. Why can't I stop?!'
Kelly kept drinking, the feeling in her own breasts getting stronger and making her wet. She realised her hand was rubbing her pussy through her jeans, and she just couldn't stop herself. She pulled her jeans and pants down so she could get in there properly, when Kelly pulled her boob away. She crouched down, stuck her head through the gate and started lapping at Emily's juices.
Emily just stood there groping at her slightly swelling tits while her cow sister licked her out. Everything about this was wrong, but she couldn't stop until she came. Fortunately, that didn't take long, and she crumpled to the floor to recover.
After a few minutes, Emily got up and put her clothes back on. She felt ashamed and awkward at what just happened, and went off to find Marcus to take her home without saying bye to Kelly.
