Still smiling sensually at the boy, the Sentinel chuckled playfully. "Mm, yeah, I like it real rough. That big cock of yours was just what I needed. If only that girl hadn't interfered. But it doesn't matter now! We're all alone and free to do what we want." She pushed her right hand into her thong and pulled on it, and then let it go so it snapped back into place. She ran her tongue slowly over her lips, adding to the seductive look. "Oh, yeah! I can already feel your penis inside of me again! Oh! I can't wait to feel it!" But then she paused, and her grin widened. "Ah, but first..." She took a few steps back as she spoke. "I've got something special for you. Why don't you turn around and take off your pants while I get your surprise ready. I guarantee that you'll love it."
