Being Watched

Although I am in my 50's, I still masturbate often.  I usually masturbate a couple of times a day, and sometimes, up to 5 times in a day.  I have found that, if I withold that pleasure for a day, I am so aroused the next day, I will be hard almost all day. It was one of those kind of days.  I work alone in a small store front with an office in the back portion.  It is not a large space and my office has a window to see when people enter the strore.  That day, I was in the office reading Solotouch and slowly stroking my cock when I heard the door open.  I look up and see a young woman come in.  I quickly stuff my cock back in my pants, zip up and go out to greet her. As I entered the room, I notice the girl is lovely, somewhere in the 19 to 22 range, slim, with long, flowing red hair, that creamy skin and small breasts.  I greeted her and she asked about something left to be sent off for repair.  I asked a couple of questions and noticed that her eyes had dropped to my crotch and her mouth had formed a large O.  I glanced down and yep, sure enough, my cock had not pushed down far enouth and it was sticking straight out having caught in my pants.   Thoughts raced through my head, I could reach down and push it down hoping it would stay or go down, or I could just leave it be.  My pants were tented out quite nicely.  I continued to ask her questions and she woulld briefly look up at my face but then, as if by some force, her eyes would return to my cock. I was so turned on as I watched her face begin to flush looking at me, so I made a decision.  I told her I needed to look up her information and to give me a few minutes.  I turned and walked back to my office and as I did, I unzipped my pants.  I know she heard it. I walked in my office and leaned against the corner of my desk.  From the outer room, I cannot be seen.  I am hidden between the glass and the wall between it and the door.  The only way she can see me is to walk to the far left of the store. I take my cock out and begin to stroke it, picturing the way she looked at my cock and the flush in her face.  After just a moment, I saw movement out of the corner of my eye.  I looked and sure enough, she had moved to be able to see into my office.  I kept on stroking and with my other hand I reached in and pulled my balls out of my pants too.  I held my hand so that she could see as much of my cock as possible.  Soon, my breathing quickened and the head of my cock began to turn purple.  I risked a look and saw her standing stock still, her eyes big, her face red.  One of her hands had moved to her left breast and was barely moving, barely squeezing, while her other hand had moved to her crotch.  Her hand was cupped and it looked like three fingers were between her legs and were flexing, pushing at her pussy in time to the stroking of my cock.  I boldly continued to look at her, feeling that swelling tide as my cock expanded and that deep pulsing began.  I came in a torrid rush and my cum shot up a foot in the air until looping back down to land on my cock and hand.  Another spasm and again as more cum shot out upon my hand.  Her eyes never left my cock and then I watched her eyes close and I saw her shudder.  When she opened her eyes, I smiled and reached for some tissue and wiped my cum.  Then I took my finger and wiped the last drop off the head of my cock and looking at her, I brought it to my mouth and licked it clean.  I swear, she licked her lips and her eyes were as big as saucers. I put my cock away, zipped up and looked and she was gone.  I walked out and she was standing at the counter.  I told her the item she needed would be back in a couple of days.  I held out my hand, smiled and said, "If I can do anything else for you, let me know".  She took my hand, and perhaps held it a beat too long, and said, "I will keep it in mind".   Her face was still blotched and red, her eyes still big and from the rise and fall of her chest, her breathing not back to normal.  She turned and I watched her cute, little butt sashay away.  Oh, to be young again. If she does come back.  If she seems interested.  My mind is filled with possibilities.  From her reactions, I do not think she has much experience at all.  And maybe, just maybe, this old dog could teach her a few new things?
