Milking the cows

As time unfroze, Mirajane knelt down in front of Lucy and Erza.

"Let's get you girls milked!" she said chipperly. She produced a bucket and placed it under Lucy's tits, then began to squeeze the nipples.

"Moo!" Lucy cried as a small amount of milk trickled down. "Moo! Moo!"

Mirajane filled up both buckets with Lucy and Erza's milk, and both women collapsed, exhausted.

"Now I-"

Mirajane once again didn't get to finish her sentence as Natsu froze time again.

He took his three frozen guildmates back to his house, then saw rhe milk buckets.

"No point in those going to waste," he said.

He drank both buckets. The milk was heavenly, but there was a clear winner. Erza.

Natsu went back home and got to work, stripping Erza naked and putting Lucy's breasts back in her shirt.

"Okay, here's what's gonna happen. Erza, you are no longer Erza Scarlet, S-class Fairy Tail wizard. You are Erza, my pet cow. Lucy and Mirajane, you believe she is my pet cow as well. You two have come to talk to me about a mission, however if I say 'Thirsty', you will both drink milk from Erzas tits. And Erza, when this happens you will go back to your human self but be unable to move!"

Natsu laughed at the chaos this could cause, and unfroze time.
