Eli could feel his fingers begin to cramp, but only dimly. He was lying on the floor, pinned there by dumbbells, one over each hand. The dumbbells had a mishmash of plates, but Eli guessed they were each about 50kg. The fingers were cramping because he had been clutching the dumbbells for over an hour, told not to let them go until he could move them. Every few minutes, Eli took a deep breath, shut his eyes, and made a heroic effort to shift the weights. As he did, the new muscles that had just begun to sprout from his body, and give him a masculine shape, flexed and bulged, veins standing to attention, with the effort. Attempt after attempt, the dumbbells remained entirely still, and Eli slumped again to catch his breath, the weights still dutifully in his grip.
Just outside of his vision, his imprisoner walked, naked, around the apartment. Eli's senses were so attuned to Adam's body that he could feel the slight vibration as his basketball pecs lifted and fell as he strode. He could tell how erect his cock was by the tenor of the slapping sound it made against his densely muscled thighs.
Eli's own penis stood tentpole straight, thickly veined and pulsing with lust. With every attempt he made to budge one of the weights, which Adam had picked up as if they were tissues, he felt the completeness of his weakness, and his erection got harder. Now, he could feel the first few drops of precum emerge from his cockhead, pool in the opening of his foreskin, overflow and dribble down his shaft to stickily moisten his tightly cropped pubes.
Ears straining for the sound of the muscle giant's activities, Eli heard him approach before he saw him. When Adam did come into view, standing above Eli's head, his flaccid penis, hanging heavily over mango sized balls, dominated his vision. It loomed closer in his vision as Adam brought his massive bulk to a kneel. One shovel-sized hand shifted his package so it lay atop Eli's face, his balls settling on either side of his throat. Feeling the weight of Adam's manhood sent a delicious thrill of emasculation through Eli, and he had to grit his teeth to stop himself from getting unstoppably excited.
"Why haven't you moved the weights, Eli?"
"I'm trying sir," Eli responded, "but they're too heavy for me."
"Why are they too heavy?"
"Because I'm weak, sir, and I need someone strong to look after me."
Eli felt a slight thickening in Adam's cock. Flaccid, it already completely covered his face. As it hardened, Eli could feel the heavy veins pulse and rise to the surface.
"Do you want me to lift the weights for you Eli?"
"No sir, not yet sir. I haven't learned my lesson yet."
"Correct. Every time you try and fail, you grow stronger. Keep trying, keep failing, and I will remove them... when I remember to."
"Yes sir, thank you sir."
As Adam pushed himself back to standing, the swell of his ass brushed, just slightly, against Eli's erection. A groan escaped Eli as he felt his cockhead, sticky with precum, leave a trail on Adam's rising ass. Eli closed his eyes and tried to keep his breath measured but, a second later, cum burst from his cock, spraying upward in a thick stream. A few seconds passed before Eli felt it drip on his stomach as the cum that had plastered Adam's ass dripped down its wide curve, succumbed to gravity, and fell.
For a long time, he didn't hear anything. His eyes screwed shut, he didn't see anything. He knew Adam was standing above him, at the very least by his bulk completely blocking out the light, and the occasional drip of cum landing on him. But aside from that, the giant did not betray his presence.
A minute passes until Adam says "Keep your eyes closed."
Eli hears him begin to shift his massive body, then stop. "And don't move," Adam adds.
Eli pressed dumbly against one of dumbbells locking him to the floor, knowing that Adam was watching. As Adam walked away, he could tell, by the loud slapping of his cock against his thighs, that he had stiffened to half-mast.
Eyes still closed, Eli heard Adam rummaging around, and felt his own cock stiffen again at the mere sound of the giant's heavy footsteps.
Eventually, Adam returned. Eli heard him position his gigantic body over him, felt the light dim beyond his shut lids as it was blocked out by Adam's colossal frame. He then heard, and smelled, the strike of a match, and the lighting of a candle.
"Open your eyes," Adam commanded.
Eli did as he was told, and opened his eyes, looking up at the spectacle of Adam above him. He never tired of looking at him, and would, if Adam allowed it, simply sit and stare at him for hours on end. Adam's thighs dominated Eli's vision, built wide with slab upon slab of straining, powerful muscle, emphasised by dark curls of hair that lead to Adam's jungle-thick bush. From this hair emerged Adam's cock, not yet fully hard, but hanging what seemed like a foot from his body, a weapon of man flesh, seated on his massive, low-hanging balls. Eli remembered the feeling of one of Adam's balls completely filling his palm, and he could feel the building of an orgasm start again.
Eli flicked his gaze higher, saw Adam looking down at him, over and through the valley of his jutting pecs. Adam's pecs, to Eli's mind, were still his best feature. Adam looked almost as if his chest had been inflated with air, his pecs hanging heavily from his body, both soft and rigid with muscle, crowned by thick nipples that, Eli had learned, were inflated and incredibly sensitive from years of muscle worship and nipple play.
Eli was not the first worshipper to enter Adam's sanctum, and his nipples were one of his favourite rituals of worship. When Eli was first brought to Adam's apartment, his challenge had been to suck, lick, and tease the muscle giant's nipples, without touching himself or cumming. Eli lasted three minutes before he was banished and made to walk home, his T-shirt visibly wet with his own cum. The second time, after weeks of training, he lasted 17 minutes, and had had the joy of feeling Adam's nipple in his mouth, red raw from his ministrations, plumpen with the giant's lust. Adam had rewarded his discipline by drenching Eli in hot cum. He even allowed Eli to spread his cum over his own penis, and bring himself to completion using it as lube.
Now, a small candle flickered in his hands, making the swell of his pecs seem even bigger. Not, not just a candle, but a stick of sealing wax. Guessing that they weren't about to start writing letters to each other, Eli reckoned that he was in for a different type of challenge.
"What," Adam asked, "is the point of pain?"
"To grow, sir."
"Are you ready to feel some pain, Eli?"
"I'm ready if you think I'm ready, sir."
With Eli's confirmation, Adam tilted the wax stick. It was burning quickly, and the movement caused a small, white stream of wax to slide down its length. Adam tilted it more, and the stream got thicker, until a single drop loosed itself. Eli braced himself for its hot impact, but felt nothing. His eyes darted upwards, and noticed that Adam was dribbling the wax on himself, over his right pec. The first few drops had slid over his nipple before they lost their heat and hardened. Adam's nipple was gloriously swollen, pink and erect, with its tangle of hair half coated in wax.
Adam continued his ritual, moving the candle to his other pec, and letting the wax drip slowly over its crest until that nipple too was swollen, and rigid with melted wax. For the first time, Adam turned his gaze to Eli, who, in response, traced his tongue around his lips, and tried, again, to move the dumbbell whose weight he was still pinned under.
Adam tilted the candle further, and the drips of wax bounced off the hardened whiteness on his pecs, and landed on Eli's stomach in quick flashes of heat. Adam continued, letting the increasingly hot wax run in streams over the mound of his pecs, before it landed, and became rigid on Eli.
Without breaking his concentration, Adam lowered himself, with a grace not expected from a man his size, so that he was kneeling over Adam, a mountain of chorded, bulging muscle straddling a pale twig.
