Mary was a 16 year old girl, livng with her single father Gabriel. Her mother had abandoned the two of them when she was 5. Outside of these traits she wasn't very ordinary. She was a genuis, she could have skipped grades, but refused to. She is madly in love with her father, however her love is different then just wanting to fuck him. She wanted to turn her father into a sexy woman and then have sex with the new woman, hopefully driving her father mad with lust and pleasure of the female form. She is Bi but leans toward being more Lesbian then anything.
Mary's father is everything to her and she wanted nothing more then to make them closer to each other, then by making her father a woman so that they could have more things in common to bond over.
Mary had a science fair project coming up. She knew her father was more then willing to help her. She plans on using the fair to turn her father into a woman and change the school while she is at it. Her main issue at the moment was to find an idea to pursue.
She could do a projet on plants and turn her father into a sexy alraune queen and the girls of her class into fairy servants.
She could do a project on robots and turn her father into a silver liquid shapeshifting robot, and her class into drones.
She could also do the classic baking powder volcanoe and turn her father into a sexy lava slime queen, to make real magma appear instead of the baking powder.
Mary had many other options she could think of but right now she needed to choose one to dedicate her time to, in order to make the nescessary transformitive liquid/nanobots/mutation juice, which ever one she needs.
