Under the scorching sun, I sprawl on my beach towel, my gaze locked on my stunning stepmother. She's a vision in her skimpy lingerie, her curves perfectly accentuated. I can't help but adjust my growing bulge as I watch her roll and stretch, her huge ass and massive tits on full display. She's oblivious to my voyeuristic gaze, her attention solely on her book. My cock throbs, aching for release, as I imagine her soft, hairy pussy and big clit. I stroke myself slowly, teasingly, my eyes never leaving her tantalizing form.
