It was Carnival time in Rio, and I was horny as hell. Hot, sweaty Brazilians were fucking gorgeous women in tropical parks all over town. I had even seen them humping on fabulous Copacabana Beach. It was sometimes more than I could bear because it seemed that every great-looking guy I saw on the beach or the street openly scratched his crotch. In Brazil that meant crabs, crabs, crabs of a tropical strain hard to eradicate once they took hold. I pined for a crab-free dip between the buttocks of a good ol' American guy - same language, same culture, a couple of home boys making it together in a foreign land.

In my position as an Army full-bird colonel attached to the Embassy for a short tour of duty in Brazil, I had to be damned careful where I dipped my wick. In those days, if caught, you got a "Section Eight," meaning you were labeled a mentally deficient pervert to be relieved of duty no matter how glorious your military record. You were court-martialed and dishonorably discharged - sometimes with a prison sentence as a bonus - all of which generally rendered you unemployable ad infinitum in civilian life. You always had to be sure the other guy wasn't setting you up for a helluva fall. Instinct had to be your guide.

My instinct told me the Marine was a "go" when I caught the glint in his eyes. With the same kind of caution I took in looking him up and down, he surveilled me as I entered the Embassy from the street, headed for the elevators. Wearing summer khakis in the tropical Rio heat, I had the advantage of loose trousers at the crotch, but the Marine's tightly tailored dress uniform could not hide the erection rising as I walked by. A quick glance in his direction led to the electric connection. We were instantly plugged into each other's minds.

I stopped at the Coke machine and fiddled in my pocket for change. I faced him while I fumbled, pulling back the fabric so he could see I was just as hot to trot as he. The glimmer of a grin wrinkled his lips. He nodded slightly toward the elevator doors and stepped away from his post, signaling another Marine nearby to cover while he was away. He went over to speak to a young American woman at the Information Desk, then, with an almost imperceptible glance toward me, he walked briskly to an elevator and stepped inside with me on his heels. The doors closed. Our gazes locked over the head of the Brazilian man who stood between us. The Marine's thumb hit the button for the top floor. The Brazilian exited on the second. We were alone.

"That's my girlfriend on the desk," he said. He spoke in a drawl as thick as molasses, a sexy southern boy. "She lives up top with the other Embassy secretaries and such. Got her own private room and bath. She lets me in there sometimes to shower or take a shit. It turns her on to think of me rubbin' my dick with her soap, or takin' a dump in her pot. Women sure are strange. Hey, we can't take too long, sir. Is that O.K.?"

I smiled to show I understood. I didn't like a lot of talking during a quickie like this. It took the edge off. I enjoyed the mystery of a hot new man. It wore off fast enough if you had sex with him a second time.

He was stripped within seconds of entering the room, So was I. Stretching out on the bed, he lifted himself on his elbows to look me up and down. His expression indicated he liked what he saw, as did I. "You got a swingin' dick for an old guy, Colonel," he drawled.

He gave me a slow, sly grin. "Hell, Colonel, back on the farm in Georgia, I grew up usin' corncobs for a lot more than wipin' my ass! But you better use a rubber. I don't want to make no mess on my girlfriend's spread, and I can only get off if I take it from the front jackin' off while I'm on my back. I don't cotton to gettin' it like a hound dog, on my knees. And I don't got crabs like the Brazilians do."

He was my kind of Marine. I pulled a lubricated condom out of my wallet. I never picked up a guy unprepared.

He lifted his sturdy legs when I knelt between them. I grabbed his ankles and spread them wide, pushing his knees down toward his chest while his fingers guided my dick into his ass. He winced. "Beats a corncob any day," he groaned. "Hey, Colonel baby, give it to me good!"

"Oh, yes," I murmured.

Excited beyond belief at the sight of his yielding young body completely at my command, I rammed my cock up his backside in swift, powerful strokes like a barbarian battering at the gates of Rome. The harder I drove, the harder he jerked himself off, so fast toward the end that his fist was almost a blur. His other hand pressed against the cum cord beneath his silky balls. Little cries of ecstasy emitted from his throat until they congealed in a strangled whisper: "Jesus, Colonel! I'm fixin' to cum!"

He popped like firecrackers, his sphincter twitching and squeezing while his semen spurted all over his chest. I watched the expression on his face change from intense pleasure to a semblance of pain. His asshole's sensitivity to my vigorous thrusts had increased tenfold after his orgasm, and his once yielding body now sought instinctively to eject me from his ass, yet nothing could bridle the frenzy brought on by his explosion and the pungent smell of masculine sex. Two men cumming together provided a heady aphrodisiac to the senses. I went wild when the semen pumped up from my balls. The flood of hot fluid caught by the condom made me feel as if I had pissed in his bowels.

Spent, my dick slipped out. We fell away from each other. Our bellies heaved with gasps.

"Off it and on 'em, Marine!" I ordered, springing out of bed. "Gotta get going. We already took too long. I guess you've shot your load for the day!" I was halfway into my clothes.

He, too, was dressing fast. "Hell, no, Colonel! I'll be sneakin' in here to fuck my girlfriend half the night! I'll prob'ly cum in her pussy till she floats off the bed!"

Startled, I stopped short of putting on my hat. "You're kidding! At my age, I'm done for after only once a day!"

He goosed me in the crotch before opening the door. "A guy my age has got a kettle full of cum! You see, an old man's poker up my ass sort of stokes up the fire and brings me to the boil," he said with a grin. "Got to maintain my reputation as a ladies' man. If I'm fuckin' women, the other guys will think I'm straight, but I can't get it up for the ladies unless I've already had a man. That's how it works for me. Can we meet again tomorrow, sir? I sure do want some more of your stuff!"

The Colonel's Stuff

I chuckled. "Sure can, Marine. We'll work something out while I'm on assignment here."

I left and took the elevator alone. I could really enjoy Rio's Carnival now because no matter how horny I got, I'd landed myself a U. S. Marine!
