Think about what has been done already. (Start here to skip previous chapters)

The deal he had made with his colleage had been to not alter the brain of his property after the girl had been marked as his own.

He hadn't really thought making her IQ drop just a bit lower than was reccomended would have such a big impact on the toy. The physical modding had been fun, mut it make her look even more retarded than she already was.

He had added some permanent tanning spray on her naked skin. Her hair was bleached as close as he could get to white and the lips had been filled up with some of the fat he had extracted from her belly. He had lasered them candypink and here eyelids were inked with thick black lines. It wasn't that original, so he had tightened her cunt and throat a bit and intensified her salviaproduction. It made the picture of a dumb fucktoy complete.

But now with the new chip... He had promised the father not to use any chips on the female. Could he keep that promise?
