I didn't remember doing it, but I clearly must have. I looked down and realized that I had my cock out of my pants and was slowly stroking it in time with her rocking hips, my own level of pleasure growing more intense by the moment. I felt my hand sliding along my under-used cock, much as it did when I relieved myself to some internet porn, only this time I was imagining my cock sliding in and out of her pussy instead of some random porn star showing off for me. I saw her hand moving and knew she was pushing her fingers in and out of her pussy, teasing herself closer to climax and, inadvertently, me along with her.

I saw her lips mouth 'oh god' as she arched her back, her legs suddenly trembling and shaking in orgasm, my own climax suddenly springing upon me at the thought of her climaxing around my fat cock.

Her full, round lips were puffed up and glistening with her own moisture, a significant amount of sexy, soft inner lip protruding and sticking down between the gap in her legs. I opened and closed my mouth several times, trying to make my words come out. "Um. Uh. Yeah. Um. In the hall closet," I finally got out.

"Okay. Thank you!" she said cheerfully, turning and walking from my office, leaving me with a short look at her completely bare, firm, round ass.

"Oh lord." I groaned to myself as I sat there, listening to her rummage in the hall linen closet.

"Oh, here it is!" She called down the hall. I heard the closet door close and a few moments later the door to the deck open and close.

"Wow," I said to myself, shaking my head at what I had just seen. I didn't have long to consider what she'd shown me when a whole new view presented itself or, should I say, herself. Sam walked out to the chair and, facing away from me, bent over to spread the white cream on her legs, ...
