AITA?

I, 27M, live with my partner, 16F. Two days ago, we were in bed, when she moved and shifted, and she described how her pussy flaps just opened, and got an air bubble trapped in there, so she made a statement saying 'i got an air bubble trapped in there'. So i went out to my garage, got my dad's old windscreen wiper he left me before he died, came back to the bedroom and shoved that thing inside her damn pussy. I held her, attempting to get it out, but she screamed 'WHAT ARE YOU DOING?' I assumed she preferred a different way, and so i stuck my hand inside. i wanted to help, but she yelled 'NO' at the top of her lungs and forcefully pushed me off, and she got upset with me. She told me things like 'You didn't ask", but i thought that her telling me that meant she wanted my help?

She's still angry at me, and it's the next day. AITA?
