I finally thought I was alone. The house was quiet, my door was locked, and I’d slipped into my room for some much-needed relief. My hand was already between my legs, computer set up, when the door suddenly opened.There stood my step-son, frozen in the doorway, eyes wide as he caught me masturbating to step-mommy and step-son porn.I should’ve been mortified. I tried to pretend it never happened. But instead, a dark little thrill ran through me.I’d told myself it was just a harmless fantasy… something that had grown stronger because my husband hasn’t touched me in so long. But the way my step-son’s gaze lingered... This isn’t just a fantasy anymore.I think I want my step-son.
