I was eager to get Shelly up onto the skyscraper’s observation deck after hours.

That would only be possible with the help of my pal Joe, who was in charge of the elevator that took tourists up to that spectacular view. Shelly was a super-hot blonde 20-year-old who I shared a biology class with at the university. I’d been asking her out for a week, but she’d only agreed to go with me on this sneaky adventure.

“I love heights,” she told me.

I was hoping she would love more than that when I got her up there alone. We showed up at the soaring downtown building at 8:55. The deck closed at nine. Joe brought down the last batch of sightseers. I slipped him a 20, and he smuggled me and Shelly onto the elevator car.

She wore a short skirt that showed off her taut legs. The rest of her body looked as limber and wiry. Her blonde hair framed her pretty features. The elevator rose and so did my sense of anticipation. I thought this a rather romantic idea, what with the panoramic view just for the two of us. Shelly gave me a smile.

The door opened at the top, and Joe mouthed “30 minutes” at me as Shelly and I stepped off. The elevator closed, and I heard its descending hum. We were alone now.

The deck was enclosed, with floor-to-ceiling windows. You could walk it all the way around, getting different views. Shelly approached the glass with a look of wonder on her face. The nighttime streets and buildings spread out below us. This was the tallest tower downtown, and the view seemed to go on forever. Some people got vertigo looking out, Joe had told me.

Not Shelly. She stepped right up to the window, pressed her nose to the glass and looked out and down. She’d never gotten around to coming up here before, she had said. I watched her soaking in the vista. City lights danced all the way out to the horizon.

I stood next to her and tentatively put my arm around her. You forget how big a deal that can seem when you haven’t gotten laid in a month. Besides, I really liked Shelly. She was intelligent and sweet. So when she snuggled against me, it made my heart go pitter-patter.

It also got my cock stirring in my jeans. Her body felt both firm and soft against me, and her scent made the hair rise on the back of my neck. Her fragrance was so enticing. She turned and tilted her head up toward me. I started to bend to kiss her, eager for my first taste of those delectable-looking lips.

A sound suddenly echoed from some other part of the observation deck. It was an animal-like grunt. It startled both of us, but of course I still tried to complete the kiss. Shelly slipped out of my embrace, however, wide-eyed and alert. “What was that?” she whispered.

I admitted I had no idea. It was more than a little spooky. We were supposed to be alone up there. The city’s glow threw eerie shadows up at us. The deck wrapped around a big central support. This segment was clear. Shelly started toward the nearest corner. I followed. Together, we peeked around, finding that long stretch of deck empty, as well.

But we heard the grunting sound again, echoing. It wasn’t quite an animal, I thought. Now it sounded like two voices. Shelly whispered, “I want to go see.” She took my hand, and we dashed silently down to the next corner.

I don’t know what I expected to find, but when we cautiously looked around this corner, my eyes popped. My cock also surged to full hardness. Against the window along this segment of the deck, two people were framed against the cityscape backdrop. They were a man and a woman. Both were naked. And they were groping and kissing.

I almost cried out in shock, but Shelly slapped her hand over my mouth. A new light danced in her eyes. She returned her attention to the couple. I gazed at them, too, totally stunned.

They were older than us, likely in their 30s. But both were in great shape—the babe a sizzling redhead with luscious tits and a gorgeous ass, the dude as muscled and agile as a boxer. Their clothing was scattered on the marble floor. The man had his hands on those sweet tits, and the woman was reaching around to knead his ass. Their mouths were glued together. They were grinding against one another, his hard cock rubbing on her flat belly.

They must have had the same idea we’d had (or I’d had anyway) of sneaking up for some private fooling around with a view. I didn’t think they’d bribed Joe, as well. They must have eluded him when he’d made the rounds to clear the floor.

The two were making the most of their opportunity. Shelly and I stayed in the shadows. I was glad she wasn’t disgusted by the sight, even though I’d rather have been doing than watching. But how often do you get to see two people fucking?

He dropped his mouth to her tits and sucked hard on her swollen nipples. She groaned. I consumed her body with my eyes. She was a real beauty. I envied the man as he feasted on her nips then knelt slowly, licking his way down her abdomen. She backed against the glass, spreading her legs. Her shaved pussy gleamed wetly, ready for him.

“Their mouths were glued together. They were grinding against one another.”

Her ass squealed against the window as he put his mouth on her pussy. I saw his tongue parting her damp folds, like a paddle cutting the water. She flung out her arms, fingers scrabbling on the glass. She thrust her crotch at his face. He stabbed his tongue deep into her.

I realized, belatedly, that this must be the ultimate case of exhibitionism. These two horny people were putting on a show for the whole city! They were deliberately displaying their naked selves to the hundreds of thousands of urban dwellers below, even if most of them would never notice the two tiny figures cavorting against the glass so many stories above the streets. Still, somebody had to be watching; they were being so flagrant about it.

In my darkest fantasies about tonight, I had never imagined doing anything like this with Shelly. Sure, I’d been hoping for a kiss and some groping, but it had never occurred to me to get her up against the window and eat out her pussy like this dude was so avidly doing to this hot babe. I understood the crazy thrill of it. To be exposed like that, to have sex out in the open that way...

Suddenly, I felt a hand on me. Shelly, still watching the couple, had reached back to touch my leg. Now her hand was sliding up onto my crotch, squeezing my prominent bulge. I bit my lip not to moan aloud.

I was standing behind her, watching over her head. I slipped a hand up under her blouse and closed it over her lush tit. The nipple twanged into hardness and I squeezed, relishing the firm feel of her.

At the window, the woman humped her pussy hard against her lover’s face. He was licking her crazily. She yelped orgasmically, and he kept his mouth in place to drink her juice. At the same time Shelly undid my fly and drew out my throbbing cock. I reached under her skirt, slipped aside her panties, and trailed my fingers along her silky groove. She jerked my meat, still facing away and watching the lovers.

He stood up, face smeared with her honey, and she eagerly knelt. She took his balls in one hand and licked his shaft up and down until it glistened before closing her mouth over his cockhead and sucking him down, inch by inch.

I pushed two fingers up into Shelly, feeling her body tremble. Her clit pulsed against my hand. She yanked harder on my aching meat. Pre-come dribbled onto her fingers.

The woman sucked her man with obvious relish. They stood silhouetted against the glowing background. He wound his fingers into her hair and started stroking into her mouth. She took every lunge of his cock, swallowing him whole. A string of spit hung from her chin.

Shelly backed up tighter against me. She pushed her ass toward my cock. I got the message. I peeled her panties off. My jeans fell down around my knees. That was enough to give clear access. She bent forward but didn’t seem to take her eyes off the others. I slipped my cockhead between her thighs and skated across her slick slit.

By the window the woman jumped up from her diligent cock-sucking. She faced the glass, putting her hands on it. She spread her fingers and thrust back her ass, primed for action. Like me, the man moved in behind his lady. She arched her back, and he slotted himself inside her shiny groove.

I drove myself up into Shelly’s welcoming pussy and held myself there. She clenched me with her slippery heat. I pulled her tight against me, groping her tits again and loving the feel of her taut ass pressed against me. She shivered with pleasure, letting out an almost inaudible sigh.

“I fucked Shelly with greater urgency, driving into her deepest parts.”

As the man started thrusting into his woman, I began stroking into Shelly. He held her ass between his hands. I did the same, savoring the firmness of Shelly’s backside. He increased his tempo, smacking into her harder and harder. The sound of his balls spanking her flesh echoed off the marble floor. I fucked Shelly with greater urgency, driving into her deepest parts. She bucked back against me, working in rhythm with me.

Pleasure flowed through me, making my balls buzz. I didn’t question what was happening. These two at the window had obviously wanted to exhibit themselves. Well, that’s what they were doing. They had two avid spectators just a dozen yards away and didn’t know it.

I wondered if I would ever have the guts to do what they were doing. I wondered if Shelly would go along with something like that.

Pulling me from my reverie, Shelly quaked, more violently than before. At the same moment, the woman at the window howled. The man pulled his cock out and sprayed his load all over her ass and back.

I came inside Shelly, jetting my spunk and gripping her close, feeling her come with me. It was the perfect shared climax. When the moment was over, she turned and we finally kissed.

Our half hour was almost up. I didn’t know what Joe would think when he found four of us up there, but that hardly seemed to matter.
