Tender trampling

My boyfriend gets off on rough stuff, and today I brought my heels to the party. Black straps, sharp points, the whole nine yards. I step right over him and let that stiletto kiss the tip of his cock. Slow, steady push. No stomping, just weight and a smile while I watch him twitch. He thickens fast, trying to lift against the heel like he wants more. Pressure builds. My sole flattens him to the floor, balls pressed, shaft pinned, every vein standing out. The harder he gets, the tighter it feels under my arch. He throbs. I grind just enough to make him gasp, then ease off so the heel can trace the whole length again. Nice and tender, just how he likes it when he's desperate. He leaks at the tip and I smear it with my sole, heel still digging light warning circles over his balls.
