Pauline, my step-sister, surprises me by being unphased by my size and initiates sexual contact

As I settled into my dorm room, a familiar face caught my attention. Pauline, my step-sister, was visiting from college. What she did next left me in awe - she didn't flinch at the sight of my impressive manhood. In fact, she initiated contact, her hands exploring every inch of my throbbing desire. The sight of her curvy frame and ample ass only fueled my lust. As she skillfully stroked me, her ample booty swayed seductively, drawing my attention to her round, firm cheeks. I couldn't resist indulging in some ass worship, my lips tracing every curve of her tantalizing ass. But the real fun began when she mounted me, her tight grip on my massive shaft driving her wild. The sight of this innocent teen riding my colossal cock was a sight to behold. As she bounced up and down, her luscious ass shook with each thrust, leaving me breathless. This was one college break I'd never forget.
