First-time anal adventure with my step-sibling

After a heated discussion, my step-sibling and I decided to take our relationship to a whole new level. I had been yearning for her for a long time, and now that she was finally ready, I was eager to explore uncharted territories. I suggested we try anal play, a first for both of us. She was game, and I was thrilled to be the one to guide her through this new experience.I positioned her on all fours, her lithe, hairless body arching before me. I teased her tight hole with my fingers, prepping her for the main event. Then, with a firm push, I slid my throbbing member into her, eliciting a gasp of pleasure from her. I began to thrust, each movement deeper than the last, driving me wild with desire.Her moans grew louder, a testament to the pleasure coursing through her. I continued to ravish her, my rhythm growing more frenzied until I reached the precipice, my hot release filling her. This was just the beginning of our wild journey together.
