I entice my bookish stepsibling during his reading session and mount his erect shaft until he ejaculates

I was lounging on the couch, enjoying my favorite book, when I noticed my stepsibling engrossed in his own reading material. His nerdy demeanor piqued my curiosity, and I decided to play a little game with him. I sauntered over to him, my lips tracing a path down his neck, leaving him breathless and eager for more. As I unzipped his pants, I could feel his excitement building, his hands trembling with anticipation. I took him in my mouth, savoring every inch of his hardening shaft. His moans filled the room as I continued to pleasure him, my own arousal growing with each passing moment. Finally, I straddled him, riding his throbbing cock with wild abandon. His intense climax left me satisfied, and I knew that this was just the beginning of our erotic escapade.
