Lust at First Sight

The Sex Workout

For reasons he’d kept to himself, despite the gleaming equipment laid out around the perimeter of the gym, Leo had recently taken to making use of the stairs during our workout sessions. As I bent over, with my head and elbows resting on the fourth step up and my toes on the edge of the bottom one, he would sit straddling my back and count each time I succeeded in pushing him up into the air by flexing my calves.

Maybe he had got off on the intimacy involved in having my body sandwiched tightly between his thighs as I struggled to raise his weight, coupled with the indignity involved in him riding me as if I were a pony? I certainly had! And the first time he had introduced this exercise into our routine, I had immediately sprouted an erection! It now transpired that the exercise’s SM potential had fired up my gym instructor’s imagination as much as it had my own.

“Up on the bottom step and bend over!” Master demanded.

This time round, I guessed the satisfaction he derived from it would be that much greater, with me being naked and him fully clothed accentuating our respective roles. My humiliation reached a new low, however, when he gripped my midriff tightly between his legs, placed his hands on my shoulders to bring his full weight to bear on my naked back and rode me with the enthusiasm of a five-year-old encountering a rocking horse in a department store.

The first twenty were soon followed by a second, and then a third set, until I could raise up my rider no more. When I finally ground to a halt, he turned around and added to my humiliation by slapping me on my reddened ass with the flat of his hand, rodeo style.

“Come on, you can manage six more…” he insisted giving me a more realistic target to aim for and another whack on the ass.

After summoning up all my remaining strength to raise him one more time in response to his latest chastisement, I then collapsed in a heap on the stairs beneath him.

“Pathetic!” Master pronounced in disgust, stepping down onto the floor to retrieve the folded belt from the rack, then insisting I resume the start position so he could take aim at my upturned arse.

After awarding me half a dozen more blows, Master tugged me onto my feet by the ear and had me stand facing the wall again with my hands on my head, displaying my reddened ass.

“Let’s have a look!” he chortled, holding up a candle so he could examine the damage he had inflicted on me more closely.

Clearly relishing the additional crimson stripes that now adorned my butt, he paused to fondle my buttocks, then reached around to check out the state of my dick, which unsurprisingly after the kicking and spanking I’d received, had shrunk to the size of that of a prepubescent boy.

While I prayed that that would be the last spanking I received that night, Master crossed the room to prepare for our next exercise by dragging a workout mat to the centre of the room and laying it down on the floor.

“Now time for some sit-ups!” he chuckled, dragging me across to the mat by the ear, where I assumed the usual position I adopted for this exercise, by lying down on my back with my knees bent.

“But this time you’re going to kiss my ass while you do ‘em!” Master added with a snigger.

With that, he turned his back to me, slid his shorts down over his thighs and stepped out of them, but to my disappointment left in place the jockstrap, I’d always suspected he wore.

“Hands behind your head!” he commanded, squatting down astride my waist with his hands on my kneecaps, flaunting his gorgeous butt in my face.

“Count ‘em out!” he then added, prompting me to begin.

Tightening my abs, I strained to raise my torso up from the mat and, despite my throbbing buttocks, managed to hold it there long enough to plant a kiss on my instructor’s ebony backside.

“One!” I called out after carrying out his bidding, before falling back to repeat the process, until, after reaching twenty, Master brought me to halt.

As I lay back to recover at the end of the set, Master demonstrated his gymnastic flexibility to me by squatting down even lower, until the crack of his arse was located directly above my face.

“Now lick it!” he demanded.

Already fired up by the sight of his bubble-butt bared to me for the first time, I needed no second asking.

I reached out to grasp hold of his thighs and hug them closer still as I prised my snout between his parted buttocks and ran my tongue along the whole length of their divide before turning my attentions to his tightly puckered hole. After running its tip around its perimeter, I eventually succeeded in prising it inside him for the first time.

“Good boy!” he murmured letting out a sigh, pulling apart his ass cheeks to encourage me to sink my tongue still deeper.

“That a boy! Get it all the way in there!” he added wiggling his ass from side to side when I eagerly complied.

Such was Master’s pleasure and joy at my debasement, that this particular exercise did not progress beyond a single set! The rest of it was replaced by me enthusiastically exercising my tongue and lips, rather than my abs, by sliding it repeatedly in and out of his tight hole, interspersed with placing a series of grateful kisses on the taut cheeks of his ass, whenever I paused to take a breath.

*  *  *  *  *  *

“On your knees, slave! Time for you to suck Master’s dick!”  Leo announced a few minutes later.

Finally, the moment I had been pining for, had at last arrived!

Despite being only inches from Leo’s crotch on a twice-weekly basis, for years, my instructor had managed to keep the size of his dick a mystery to me. I had no idea of what lay hidden beneath the rugger shorts or gym sweatpants that he would habitually wear, as his equipment was always tightly tucked away, giving me little indication of its true dimensions.

I’d begun to suspect that maybe he had something to hide. But I guess like many Black guys, he was irritated by others’ assumption that he would be well-endowed and thus be disappointed when his dick turned out to be smaller than they’d hoped.

But any worries he might have had were needless as far as I was concerned, as large or small, fat or thin, given the opportunity to do what I’d been longing to do for so long, I would willingly wrap my lips around it without a second’s hesitation!

Clearly aware of my long-standing frustration, Master teased me by making me wait a little longer, by turning his back toward me as he pulled off his gym vest to reveal his muscular shoulders and slender waist, before slowly easing down his jockstrap and letting it fall to the floor.

Given a picture of the back of Leo’s bare torso as he’d hoisted a dumbbell above his head, had been sufficient to set my pulse racing when I’d seen it displayed amidst the gay personal ads, unsurprisingly, the sight of the entire rear of his stunning gymnast’s body, first hand, left me struggling to contain my lust!

So, when he then turned around to face me, displaying his perfectly proportioned member, fully erect, with a huge grin on his stunningly handsome face, I eagerly rose from my supine position and clambered toward him on my hands and knees. Overcome by emotion at having my fantasies finally fulfilled, rather than immediately envelop his cock in my mouth, I chose instead to demonstrate my gratitude to him by covering the tops of his feet with grateful kisses.

For his part, Master looked down on my display of submission indulgently and patted me on the head as I slowly licked my way up his legs until I began to smell traces of the manly aroma emanating from his groin.

With my passion heightened by the smell of testosterone and the salty taste of his sweat, I briefly paused to sample the insides of his smooth-skinned thighs before anointing each of his, almost hairless balls with my saliva.

Pleased by my ministrations, Master beamed down at me and lay a hand on my head to convey his approval as I lovingly ran the flat of my tongue over both sides of his scrotal sack. As his excitement grew, he wrapped his fist around his shaft and began tugging on it, encouraging me to envelop his testicles in my mouth to enhance his pleasure still further as he did so.

Unable to hold himself back a second longer, soon afterwards, Master extracted his balls from between my jaws and slid his dick between my parted my lips, prompting me to commence licking clean its exposed head with gusto.

As I gorged myself on Leo’s silky-skinned shaft, I recalled how, after our first meeting, I had renamed him LAO and congratulated myself on persuading the personal trainer, I had lusted after for so long, to finally permit me to pay homage to his masculine beauty by licking him from the pallid soles of his feet to the purple tip of his penis. Not to mention, awarding me the unanticipated additional delight of rimming his arse en-route!

In response to my adulation, my athletic mentor breathed in deeply and showed his appreciation of my total surrender to him by heaving satisfied sigh, then, as his excitement mounted, thrust his dick all the way to the back of my throat.

Willingly, I opened up my gullet to take as much of his manhood inside me as I could, but when I paused to take a breath, Master quickly took control away from me by grasping the back of my head and thrusting his cock back inside me until my nose was rubbed up against the stubble of his curly black pubic hair.

Aroused as much by his dominance as his muscular splendour, in a further display of my submission, I locked my arms together behind my back to voluntarily render myself helpless and encourage him to fuck my face as rapidly, and as deeply, as he pleased.

But to my surprise, Master chose not to cum this way, and after just a few minutes of thrusting his shaft down my throat, withdrew his cock from my mouth and led me by the ear across to another of the exercise machines instead.

*  *  *  *  *  *

In addition to doing calf-raisers on the stairs, Leo had clearly identified another exercise with a potentially erotic side to it, which he was keen to try out on me before he reached his climax. It seemed the innocuous triceps’ pull-down, an exercise he regularly had me perform toward the end of our sessions, had stirred his passions, as much as it had my own.

With my hands curled around the ends of the short bar, standing facing the pulley and the stack of weights it was attached to by a wire, I was expected to pull it down below the horizontal, with my back straight and knees bent, then release the pressure and repeat it a dozen or more times, until I had completed a set of four.

However, to prevent my arms from sticking out to the side and ensure I was exercising the right muscles, my instructor would invariably position himself behind me with his hands pressing my elbows inwards to make certain I maintained the correct form. The intimacy this process involved had often made me wonder if Leo was as turned on as I was when he encompassed me – but, due to the jockstrap, I had never felt anything untoward pressing up against my backside – at least not until now!

This time, I stood before him completely naked with my hands occupied clutching the bar, with my taut backside stuck out, crying out to be fucked!

As I commenced the first set of twenty, rather than taking hold of my elbows as I began to press the bar downwards, he opted instead to slot his erect cock into the cleft beneath my buttocks and reach around me to cup my pecs in his hands to fondle them as he thrust his steely shaft back and forth to enhance his excitement. 

As one set followed hard on another, Master’s thrusts gathered pace and whilst squeezing my tits, and pinching the tips of my nipples between his hardened fingers, he sank his teeth into the back of my straining neck, one side after the other, to imprint a pair of matching hickeys on my trapezius muscles and brand me as the slut he knew me to be!

“Fuck me!” I pleaded shamelessly, as I felt the heat of his body and the strength of his arms wrapped around me, abandoning my attempts to push down the bar one more time, in favour of holding my thighs tight together and thrusting my ass back to meet his forward lunges.

“Please fuck me Sir!” I then added more respectfully, fearful he might interpret my words as a demand rather than the further mark of my submission I’d intended.

“Okay, since you ask so nicely!” Master chuckled, breaking off to drag me across the room, with his primed dick swaying from side to side between his wide thighs.

“Up you get!” he instructed, when we arrived back at the workout bench, “On yer back, with your legs in the air!”

While I eagerly positioned myself as he had demanded, Leo tore open sachets containing condom and lube and after donning the former, quickly coated his dick and my hole with the latter, and wiped his hands clean on a sweat-towel. He then pulled my ass forward until it hung over the edge of the bench, hooked my legs over his shoulders and whilst folding my body beneath him, aligned the bulbous end of his ebony dick with the pink lips of my anal ring. Standing astride the bench with my torso resting on its padded surface, he then eased his thighs forward to sink his dick inside me for the first time. 

With our faces now mere inches apart, I was able to witness his handsome features break into a sadistic smile as he thrust his shaft ever deeper, until its whole length was fully embedded.  After which, he encompassed my whole body in his powerful arms and commenced thrusting it in and out of my ass at an increasingly rapid rate.

As his passion grew, he gazed into my eyes with a triumphal grin on his face and pressed his mouth against my own, forcing his tongue between my lips so he could kiss me as he continued to fuck me.

Eager to please him in every way I could, I raised my flailing arms to fondle his chest as he kissed me and caress the tips of his perfectly formed nipples between my fingertips. But when a few minutes later, I moved on to massage his shaved scalp, he broke off from kissing me, to place my hands firmly back on his tits, after which he wrapped his sinuous hands around the back of my neck to provide him greater leverage so he could fuck me deeper still.

As the pace of his thrusts began to accelerate once again, I brought to mind the array of humiliations my instructor had imposed on me that evening – from the surprise public dressing down he had given me on my arrival, to having me perform my workout naked and belting my ass should I fail to achieve the targets he set for me. The indignity of having to get down on all fours like a dog to kiss and lick his trainers, then breathe in their pungent odour as he fingered my exposed ass and fondled and kicked my genitals at will, only to then be ridden like a bucking bronco and belted on the ass as he shouted out “Yee-haw!”

But alongside these recollections of my debasement by my long-suffering personal trainer and the tests of my obedience and submission he had imposed on me, there also came the rewards I had dreamt about experiencing for so long - the pleasure of seeing Leo’s gym-toned body naked for the first time, kissing him on the lips and being permitted to sink my face between his perfect buttocks to lick out his ass, before finally being allowed to worship his stunningly beautiful dick!

Independently of these arousing thoughts, my body also seemed set on achieving its own release, after being teased and tormented for so long, as the pounding my sphincter and prostate were receiving from my Master’s hard dick, combined with the pressure from my aching bladder, to leave me uncertain whether I was about to piss or come!

Feeling my ass-muscles tighten around his shaft as my orgasm began to kick in, Leo parted his lips from my own to utter a triumphant cry of satisfaction as we both reached climax as one man.

No longer in control of my bodily functions, without need of touching myself, I found myself hurtling toward the most tremendous of orgasms and ejecting wave after wave of hot spunk across both my own and my Master’s neck and chest. Whilst deep inside me, I felt my master’s cock erupting in unison, in a series of ground shaking, cathartic spurts.

Once both of us were fully spent, we remained with our two bodies melded together, until a grinning Leo finally extracted his cock from my rear and permitted my cramping legs to fall to the floor.

Thinking our encounter over, I was about to dash to the loo to empty my bladder, only for my Master to take me by surprise by issuing a further command.

“Hold on, slave boy! I’m not finished with you yet!”

“I’m taking you out for a run!”
