Marinette wakes up to find herself having been turned into a futa.

Marinette Dupain-Cheng woke up abruptly to the sound of her alarm clock. She winced as she felt the joint in her neck pop and crack as she wiped droll off of her face. She had fallen asleep on her desk. Again.

Marinette spent half a sleepless night (the rest she slept) working on her newest design, a purse with a specialized pocket to hide her kwami Tikki, complete with a small light, a little compartment to hide cookies for her and a little bed and blanket. Tikki was her friend. She would not be the first half of Paris' heroic duo - Ladybug, holder of the Ladybug Miraculous - without her. It was the least Marinette could do for her.

Marinette wandered to her bathroom like a zombie, rubbing her eyes trying to wake herself up. She had a nightmarishly bad bed-head. She turned on the shower-head. The mirror fogged up as she robotically undid her clothes and stripped before climbing into the tub, letting the water run in her hair and down her back.

She felt the tension in her shoulders drain as the steaming water beat against her. She washed her hair with Strawberry shampoo, reaching for a towel when some accidentally got into her eyes.

When she felt that she was fully clean, Marinette walked out of the shower and dried herself off. She wiped the steam off of the mirror, getting a better look at herself. She grabbed her day clothes off from the toilet seat. She slid her panties up, but something felt off. She looked at herself and noticed something shocking.

There was a lump in her private area. She pulled the front of her panties opened to see what it was.

Tikki jumped out from her little bed at the sound of Marinette screaming in the bathroom.
