Taboo Encounter: Stepdaddy Watches Stepdaughter Fuck Herself

I lay back on my couch, my heart racing with anticipation. StepMom had bought me a special gift - a thick, veiny dildo shaped just like StepDad's cock. She said it was time I learned how to please myself properly. My hands trembled slightly as I tore open the package, revealing the impressive silicone shaft. I couldn't wait to feel it stretching me open. Spreading my legs wide, I brought the tip to my already dripping entrance. Slowly, I began to sink down onto it, biting my lip to stifle a moan. It felt so big, so much bigger than my small fingers. Inch by inch, I took more of it inside until I was fully seated. "Oh fuck," Lost in bliss, I barely noticed when the door creaked open. Suddenly, I heard a sharp intake of breath behind me. Freezing mid-bounce, I glanced over my shoulder to see StepDad standing there, eyes wide with shock...and undisguised lust as he took in the lewd sight of his stepdaughter sitting on a huge dildo, tits bouncing with each movement.
