I’m sixty years old and employed as a night watchman. For the past month I’ve been working the four-to-midnight shift at a small suburban shopping mall. I’ve been in the security business all my life, and for the most part it’s been pretty routine. Oh, I did catch a burglar in the act one time, and early in my career I apprehended a purse-snatching office messenger, chasing the guy half a dozen blocks before corralling him with a flying tackle, but basically I put in my time and go home. Last Friday night, however, I had more excitement in twenty minutes than I’ve have in all my years in the business.

Little did I know what was in store for me when Stella, my favorite tenant in the mall, informed me that she’d be working late that night and asked would I check in with her periodically, just to be sure everything was okay. I could understand her apprehension, as her travel-agency business is located in the lower concourse, underground, and while the area is well lit, it certainly is desolate late at night. I told Stella I’d be glad to keep an eye out for her.

Now, I’d do the same for any tenant, but I especially like the idea of providing a little extra security for Stella. For one thing, she’s a real nice person, always there with a smile and a friendly wave. For another. she’s one good-looking woman. I’m no spring chicken, for sure, but Stella, with her curly brown hair, big eyes and neat, compact little figure, never failed to bring my old cock to attention. Yeah, I can still get it up, a fact my lady friend Louise can attest to, but the old boy usually requires some manual attention before he’ll rise to the occasion. Now, with Stella, all I had to do was glimpse her smile or wiggling little bottom, and presto! my cock was swelling and pressing hard against my trousers.

Anyway, it was about nine o’clock, right after the mall had closed for the day, that I decided to see how Stella was doing. I rode the escalator downstairs and walked down the hall to her travel agency, checking the doors of the other businesses along the way. When I got to her place and looked inside, I saw her working at her secretary’s desk. Glancing up, she saw me and smiled.

I unlocked and opened the door and asked if everything was all right.

“I’m fine, Charlie, thanks,” Stella said. “But I’m going to have to stay later than I thought. Maybe you’ll check back in an hour, okay?”

“You got it,” I said. “No problem.” I thought I detected a mischievous gleam in Stella’s eyes as I closed the door and started down the hall, but I didn’t think much of it at the time.

I was sipping coffee at a security station when I checked my watch and saw that it was ten o’clock. Back downstairs I went, but this time when I looked through the window of the travel agency, I didn’t see Stella. In fact, the outer office was dark. Assuming that she was working in her office in back, I unlocked the door and went inside. As I switched on my flashlight and started toward her office, I heard a woman moaning.

For a second I froze, and then, instinctively, my hand went down to my gun holster. Drawing my gun, I moved stealthily toward Stella’s office and saw that the door was ajar. I knew I would never forgive myself if somehow, some way, someone had gotten into the lower concourse and found Stella alone down there. With my heart pounding in my chest, I peered around the door.

I gasped in total surprise. I don’t know what exactly I expected to see, but it sure as hell wasn’t Stella bent over her desk with a guy fucking the bejeebers out of her from behind. I ducked back behind the door, swallowing hard as I heard Stella ask the guy to slow down and make it last.

What to do? A voice in the back of my head was telling me to leave, for surely Stella was in no danger. But it was a tiny voice, to be sure. Making much more of an impact on me was the intense excitement spiraling through me, as evidenced by the rapid swelling of my cock in my trousers. Stella’s moans and groans were singeing my brain.

I switched off the flashlight and returned it to its place on my belt. I put my gun away, too. I peeked around the door and this time allowed myself to savor the scene. Stella’s yellow blouse had been undone, and her bra-encased tits were mashed against the glass-topped desk. She was holding tightly to a small desk lamp and her eyes were closed, her face flushed with excitement. Her pleated skirt had been thrown up over her back, and her lovely taut ass was absorbing the shock of her friend’s repeated thrusts. On the floor at her feet were a pair of white panties. The guy, whoever he was, looked almost comical standing there with his briefs and pants down around his ankles, but he was a good-looking dude, around thirty, and there was nothing funny about the big cock he kept banging into Stella.

By now I was so hard I hurt. Again I ducked out of sight, but only long enough to unzip my trousers and haul out Old Faithful. I hadn’t been this hard in twenty years. Once again I peeked around the door, my whole body alert to the moment, alive with excitement.

“Let me finish in your ass,” the guy said suddenly, his voice raspy with passion. “I want your hot ass.” He started to withdraw from Stella’s pussy, but she stopped him.

“No, not there,” she barked. “In my mouth. I want to taste you tonight.”

The guy seemed disappointed, but he pushed back inside Stella’s pussy and resumed fucking it with steady, measured strokes. I, too, was disappointed, for it would have been a sight to see Stella’s tight little bottom swallow up her friend’s big cock, to hear her moans of delight as he sheathed his sword in the dark confines of her rear-passage.

I continued to stroke my cock, but carefully, wanting to prolong this totally unexpected thrill for as long as possible. My eyes remained glued to the fucking couple, and I tried not to blink for fear of missing even a split second of the action. The man, with his hands locked on Stella’s hips, continued fucking her, picking up the pace now on her orders.

“Yes, like that,” Stella crooned. “I’m close. Harder, harder!”

The guy reacted immediately, and within seconds he was banging away for all he was worth. Stella started yelping and then, a moment later, let out a wail of pleasure as she exploded in orgasm. I had to stifle a groan as I squeezed the base of my cock hard. And then the guy was stepping back, his cock leaping up in the air as it exited Stella’s pussy.

Stella, pushing herself up off the desk, spun around and dropped to her knees, her hungry mouth quickly engulfing that ready-to-tire pistol. The guy came-in buckets, judging from the semen that spilled out of Stella’s mouth and ran in tiny rivulets down her chin. Yet she managed to take down most of it, and when, after a final swallow, she smiled up at her friend while rubbing his come-coated cock all over her face, I choked back a moan and smeared my seed all over the office door.

I couldn’t remember the last time I had come so hard. As I stood there on rubbery legs behind the door, clutching my heart with one hand and my ejaculating cock with the other, I entered another world. Then, still breathing hard, I stuffed my cock back into my trousers and this time heeded the voice in my head that told me to leave, and quickly.

I was still trying to compose myself several minutes later at the security station. I figured the guy with Stella must have entered her office during mall hours, certainly before nine, and remained there when the mall closed. There was no way he could have sneaked downstairs after nine without me seeing him. But what I couldn’t understand was why they would fuck in Stella’s office instead of his or her apartment. Or if that wasn’t feasible, a motel. And why, if Stella expected company, had she asked me to check on her periodically? I was puzzled.

I saw Stella riding up the escalator, and I suddenly remembered coming all over her office door.

“Thanks, Charlie, I appreciate it,” she said when she was standing in front of the desk. To look at her, you’d never guess she’d just been soundly screwed. And where was her friend, anyway?

“Will you let me out?” Stella asked. “Sure,” I said, casting a glance in the direction of the escalator. I walked Stella to the main entrance of the mall and opened the door for her.

“Oh, by the way, Charlie,” Stella said, “I’ll be working late again next Wednesday night. Do you think you can check in on me once in a while?”

I smiled. “Anything for a pretty lady.”

Stella chuckled softly. Standing on her toes, she gave me a kiss on the cheek. “You’re a doll, Charlie.” She paused and then said, “This job must really get to you at times. I mean, it’s got to be awfully boring. Maybe we can think of a way to make it more exciting.”

I didn’t know what to say.

“Why don’t you come into my office sometime. I’m sure I can work up something special for you. For your next vacation, I mean.”

“That’ll be nice,” I managed to say.

Stella thought for a moment. “Maybe Greece. Do you like Greek culture, Charlie?”

I swallowed hard. “Sure, Greek, I mean, Greece is good.”

Stella chuckled. “It sure is, Charlie.”

A few minutes later she was in her car and driving out of the parking lot. I hurried to the lower concourse and went directly to the travel-agency office. There was nobody there.

Well, here it is early Wednesday morning, and I still can’t figure out what the hell’s going on. One things for sure, though. Tonight I’ll be checking on Stella every half hour or so. And something tells me I’m going to watch her take it up the ass.
