Intimate gaming session with petite stepsister turns steamy

After a long day at work, I was eager to unwind with some quality time with my girlfriend. However, she had other plans and was too absorbed in her favorite video game to even notice me. As I sat down next to her, I couldn't help but get turned on by the sight of her small, perky tits. In a moment of desperation, I found myself seducing my stepsister instead. The sight of her petite body and innocent face was too much to resist. As I guided her to the couch, I couldn't help but feel guilty, yet incredibly aroused. Despite my initial hesitation, I found myself thrusting into her from behind, her small tits pressed against my chest. The sight of her bent over, her small ass swaying with each thrust, was almost too much to handle. The intensity of our encounter left us both breathless, but satisfied. As we cleaned up, I couldn't help but wonder if my girlfriend would ever find out about our taboo encounter.
