On her skirt

I tried desperately to keep my rapid breathing quiet as I felt my orgasm approaching. The woman stood only a couple of foot from my naked body, oblivious to my presence. As she finished pulling on the jeans, she twisted this way and that, looking in the mirror. The tight arch of her ass was well outlined, as were her sexy legs.

As I felt my release approaching, I knew I had to find somewhere to cum that she wouldn't see. I was almost too late as I spotted her discarded skirt by my feet. Quickly crouching, I continued the quick pumping of my cock as I pressed the head into the soft material.

Looking at her, so close to me, I came. I had to bite my lip to avoid alerting her with a sound as I began to pump my spunk into the skirt. My world narrowed to the incredible release of emptying my balls.

With my attention diverted, I missed her removing the jeans and was nearly discovered as she reached to grab her blouse then skirt. I moved to the edge of the cubicle, attempting to breath quietly as she promptly redressed. Soon her clothing was back in place and she picked up the jeans as she turned to leave.

As she turned, my eyes studied her ass and a smile creased my lips. The back of her skirt now sported the sticky, white-ish shine of my cum across it. It formed a line across her toned bum, with several large spots lower down. As she reached for the curtain she pause for a split second, and seemed to sniff slightly as her brow wrinkled. As she dismissed her concerns, she opened the curtain and stepped out. Following her, I watched the cum covered ass saunter toward the dressing room exit.
