Jackie and Sydney's relationship was great. They loved each other, never lied and were willing to experiment. When Breath of the Wild came out, they played through it and loved two characters. Mipha and Urbosa. Two beautiful girls for the lesbian couple to fawn over. They knew it was only a matter of time before the witches of Costume in a can would come thought for them. One night while checking their emails, they saw a newsletter for the store with new stock that just so happened to be on their wishlist.
Jackie and Sydney returned from the store with the two cans. "Who gets what can and who goes transforms first?" Sydney asked. They thought about if for a while until Jackie said "How about Rock, Paper, Scissors? Winner gets first choice while loser must change first." "Sure, two out of three?" Sydney asked. "Alright." Jackie replied. Jackie took the first round while Sydney won the second one. "This is for all the marbles." Jackie said. "Rock, Paper, Scissors, Shoot!" Jackie shot out paper while Sydney shot out rock. "Yes! I call Urbosa!" Jackie called out triumphantly. "I knew you'd pick her. You just wanna be taller than me!" Sydney said smirking, picking up her can. "Guilty as charged. Now, spray yourself." Jackie said sitting down.
Sydney sprayed herself and got ready. Her eyes turned yellow while some of her skin started turn bright red while some lost of it lost its color and turned pale white. Her nose shrank into her face as her forehead started growing out. Her blonde hair fell out and faded into nothingness as something was growing out of the back of her head. It slowly got longer and longer when two fins grew to the sides. Her teeth started growing sharper and sharper. She smiled, showing them off. Her ears disappeared as long fins draped of where they'd be.
The changes continued down her body as her breasts shrank to nothing. "How do you think I feel all the time?" Jackie said. Sydney's changes continued as her shoulders grew out and her muscules built up a little. Down near her rear two more fin-like appendages grew out while her womanhood changed into Mipha's. Down at her feet, her toes merged into two long fins built for swimming. She started shrinking down until she was only 5 feet tall. Just a couple inches shorter than Jackie. "Enjoy it while is lasts." Sydney said, noticing the change in voice.
Finally, Her transformation ended with her jewelry and sash adorning her. "Mipha's grace is now ready." she said kissing Jackie. "Now pop that can and get ready to be 6 feet tall." She said sitting down, adjusting her head fin so it wouldn't ram against the couch.
Jackie sprayed herself and sprayed and sprayed. She sprayed so much that she emptied the can. "Jackie! You won't change back for two months now!" Sdyney said standing up. "What? It's not like we need to be anywhere. Besides, are you saying you wouldn't want Urbosa to be your girlfriend for a couple months?" Jackie said smirking to her. Sydney turned as red as parts of her skin. "I never said that..." she said trailing off.
Suddenly, Jackie started getting shorter and shorter. "Why didn't your transformation stop?" Jackie asked. "It did, you're really tall now." Sydney said looking up at her. Jackie's Hair started getting longer and longer until it touched the floor, it also turned an even brighter red that the girls thought wasn't possible. Her ears started stretching to a point and her nose grew out a little as well.
Her normally chubby body started flattening out showing off an impressive six pack. Muscles started replacing the fat in Jackie's body as it all migrated to two areas. The sudden growth had caused her clothes to rip showing of every inch of her new body. "Excited?" Jackie said, finding that she now sounded like Urbosa. Sydney then found out that her head fin could move on its own and was currently wagging at the site of her naked lover.
Her skin started taking a darker tone as it spread around her body. She flexed her muscles for Sydney who was blushing really hard. Finally, her clothes started changing and started putting itself back on her body. Her hair lifted itself up, being locked into place with two rings making it into the ponytail Urbosa normally wore.
When both transformations finished, Jackie swept up Sydney and took them to her room.
