A few days have passed, and now every day Estella demands breakfast in bed served with my milk. I also discovered what it was that she put in my ear apparently some kind of small slime was released into my brain to make me more "daring".
Basically, she wanted to test something that would make me more naughty and perverted, since she was curious about my brain and how it functions in regards to my personal control and personality.
This little thing is inside me, doing who knows what, while I can only serve Estella as a maid. She even forced me to wear maid outfits that don't fit well because I have too large of breasts.
Our relationship boils down to Estella using me sexually every day, but while she's having fun, I'm plotting. I've also tried my own milk, and it's delicious. The most important thing is that my magic seems to have temporarily become 3 times stronger.
