Mój pasierb mnie obserwuje

I always feel his gaze on my butt. In the shower or when I relax in bed while his stepdaddy is not around. He thinks I don't notice him, but to be honest, it turns me on somehow. I chose the moment when his stepdaddy is at work and we are home alone to take a shower. I knew he would be nearby again, but this time I will give him what he has long desired.
