Caught my hand in the cookie jar behind my stepsister's enticing rear. Her OK signal ignited a steamy POV session, complete with Spanish subtitles for added flavor.
I was casually chilling behind my stepsister's house, indulging in some self-pleasure when all of a sudden, I spotted her big, juicy ass. It was a sight that was just too damn irresistible! I couldn't help but be drawn to it, and before I knew it, I was right up close, getting a front row view of that amazing ass. The sight was so fucking hot, it sent me over the edge! I was completely lost in the moment, my hand moving faster and faster as I stroked myself to orgasm right there, in front of her. The whole time, she had no clue, oblivious to the steamy show I was putting on for her. The thrill of almost getting caught made it all the more exciting. Afterwards, I kept my cool, acting like nothing happened. But deep down, the thought of almost getting busted while jacking off behind her big ass was enough to get me rock hard all over again.
