Jess settles on the duck vial. Ducklings were always so cute! The way they looked, the way they waddles around. It was just something she had to try.
"OK", Jess says, "Let's try the...duck vial!" She blushes a little, but doesn't back down.
"Sounds good!" Mary answers. "Something different. This'll be fun!" Mary looks over the box of vials and pulls out the duck vial. It's colored faintly yellow. "Since we're sharing, only drink half." Mary waited for Jess's nod before gulping down half the liquid and handing it to Jess who drinks the rest of it.
Mary begins to feel the sensation of the transformation and smiles knowingly at Jess. "Here it comes!" And sure enough, the transformation begins. Mary starts sprouting small yellow feathers, followed shortly by Jess. The two giggle and run their hands through each other's growing feathers.
The feathers soon start to fill up their clothing. Their shirts look like they've been stuffed with cotton filling. Soft, downy yellow feathers protrude around the neck lines and sleeves. Their breasts were hidden by the massive amount of feathers, so that now, they had only a small rise to show where they were.
As the feathers kept filling in, the two girls' arms began to transform into a wing. Their hands and fingers lengthened and were covered by slightly longer feathers than on their bodies. They still had mobility, but their arms now resembled wings.
Near to the same time, the two changing girls' pressed their hands to their bottoms as tails started growing. The mass of flesh and feathers stretched tight their pants and with a loud rip, they pants fall off and expose the tail behind. The tails stopped about a foot and a half out, and completely covered in feathers. Jess stood up to look around at her tail which forced her to arch her back slightly. Mary giggled, and Jess turned to look at her. "Look at us, we're almost ducks!" Jess could only nod before the next change came.
Jess felt herself seeming to shrink, at least the bed was coming closer. But, she wasn't shrinking, her legs were shortening and turning bright orange. They quickly thinned and Jess and Mary watched as their once human feet sprouted into a three toed webbed foot. Jess's legs were so short now that as she turned around and walked a bit, she waddled comically, her duck bottom swinging back and forth behind her.
The last changes came to the girls' faces and heads. Their lips stiffened and grew straight out. Mary looked down cross-eyed at her new beak. Jess held onto hers, marveling at the odd feeling of the hard beak on her.
Jess and Mary had now become half-ducks, with soft yellow feathers. They almost looked like the cartoon ducks from Disney, like Donald.
Mary asked, "Well, what, d'ya think?" Jess nodded happily, "This is amazing. I'm a duck!" Mary could only giggle and nod herself.
