I want all your attention on my ass
You can't pull your eyes away from that ass, round and bare and demanding every last bit of your attention.
You feel the want settle low in your gut, something immediate and physical, not subtle at all. You trace the curve with your gaze like your hands already know the shape. You notice how the light catches the softness there, making you lean closer to the screen without realizing it.
You were looking at something else a moment ago, but now that doesn't matter. You belong to this image completely, held there by the weight of pure, uncomplicated desire.
