My stepsister's intense arousal forces me to penetrate her petite vagina

I've been harboring a secret desire for my stepsister ever since she moved in. Her voluptuous curves and luscious ass have been driving me wild. One day, I caught her pleasuring herself, her tight little pussy gaping in the most enticing way. I couldn't resist any longer and plunged my throbbing member into her. She moaned in pleasure as I stretched her petite vagina to the limit. But that wasn't enough. I needed more. I flipped her over and continued to drill her, her ass bouncing with each thrust. The sight of her fat, bouncing ass only fueled my desire further. I took her in cowgirl, my cock disappearing into her depths. Then, I had her bend over and fucked her hard, her ass clenching with each thrust. The sight of her gaping hole only served to drive me wilder. I continued to pound her, my lust only growing with each thrust. Finally, I released my load, filling her petite vagina with my hot cum.
