After a grueling day at work, I unwound with a soothing shower. Little did I know, my stepsister was lurking behind the curtain, her eyes glued to my every move. The audacity! But let's face it, voyeurism is a classic pastime. So, instead of getting mad, I decided to seize the moment and give her a show she'd never forget. As she watched, I began to pleasure myself, my hand moving rhythmically up and down my throbbing member. The sight of me self-indulging seemed to excite her, and before I knew it, she was on her knees, taking me into her mouth. The taste of her was intoxicating, and I lost all sense of reason as I plunged into her, our bodies entwined in a fiery embrace. The forbidden thrill only added to the intensity of our encounter. As we continued our passionate rendezvous, I couldn't help but marvel at the audacious brunette, her eyes filled with a mix of fear and desire. This was just the beginning of our steamy, post-bath escapade.
