Niklaus point of view:
Cold showers became the norm of the night. Each time I closed my eyes, erotic dreams featuring Maya as my companion dominated my senses.
I knew it was my subconscious playing tricks on me. It was taking advantage of the memory of Maya in bed and replaying in my mind with its twist borrowed from my past imagination and I'm not going to lie, I enjoyed it but not when I had to relieve myself for the umpteenth time in the bathroom.
Seeing that sleeping was an unachievable feat, I stayed awake the rest of the night, using that opportunity to go about how to punish my daughter.
Isabella had inherited her mother's manipulative trait or rather her late mother inculcated it in her. She knew I was feeling guilty for her mother's death and tended to take advantage of that.
That was why I didn't have the heart to spank her instead resorted to giving her punishments but it seems the girl was now immune to them.
