The prisoners are helpless to the pirates advancements. The cells slamming open and the hairy sailors stomping inside. One by one the men are taken by the crew. Some locking lips with a deckhand as their hair turns grey and their body fit the sailors build. Others claimed by the quartermaster, forced against stinking pits and hirsute chest as they too assimilate into the captain's ranks. Nate wondering when his own ordeal is going to begin, trying to plot a route out of these cells. He could maybe overpower whoever opens it if they're a lankier sailor. Then just charge out before someone gets their cock in his ass. But of all the pirates that could open his cell, it's the captain himself that greets Nate.
"Count yerself lucky, lad. Yer captain's having his fun!"
"You're not going to be my captain!"
"Aye? That so?"
Nate gulps, running to the captain and trying to squeeze past him and through the door. Not even getting to the mans side before the pirate wraps an arm around the prisoners stomach. Nate letting out a gasp as he is pushed back, slamming into the stone wall and collapsing to his rear.
"Ye a defiant rat? Darin' to run from his captain?"
Nate can't muster a response. The captain undoing his clothing. Dropping jacket to the floor then adding his hat to the pile. The prisoner refusing to look at his captor, just seeing more clothes be discarded. Pants sitting at the top of the stack, as the pirate finishes undressing. Nate still refusing to look, and the pirate growing irritated.
"Look at ye! Barely a man! Barely loyal! Not worth the muscle on ye chest."
The captain brings a hand to the prisoners shoulder. Gripping onto him tightly, Nate finally looking up to the pirate. Looking past his meaty legs. Looking past his honed abs. Looking past his bright red beard and menacing grin. Staring him dead in the eyes as he starts to feel weak.
"I'll be taking me share, cabin boy."
Nate can't defy the pirate anymore. Suddenly exhausted, only able to move his eyes to find out what's going on. A foreign arousal being mixed with the fatigue. Glancing down to his throbbing dick, then back to the captain. Seeing the older man's torso broaden. A mix of more red and grey hairs lining the sailors chest. More muscle compacting into his pecs and abs.
Nate's groans grow louder, his eyes looking down to his dick which leaks pre, then to his own stomach. Nate's well muscled body shrinking before his gaze. Pecs deflating to a smooth chest. Stomach becoming thin and youthful. Hairs receding into his torso.
With everything he loses, the captain grows. The pirates arms ballooning in size, veins bulging under the skin. While Nate further drains in strength. Pits becoming shorter and arms spindly. His pre now dripping down his leg, as the prisoner follows the liquids travel. Seeing the lasts sign of his muscle fade away. Legs reforming into an almost petite state. While the captain's grows, his own lower half swelling with muscle.
"Ye found yer use, matey."
Nate looks the captain back in the eyes. A few more wrinkles on the pirates brow. More grey hairs taking over the red on his chin and scalp. The intensity of his changes forcing the captive to look away from the sailor and to his cock once more. Spurts of pre leaking from the tip, desperate for full release. The captain releasing a grip on his subordinate. Nate quickly bringing his hands to his dick and stroking as fast as he can. Shooting spurts of cum over himself and the floor, while the sailor who changed him nonchalantly changes back into his clothes.
When his balls are finally emptied, Nate rests against the walls. Panting harder than ever before, and covered in sweat and cum.
"Ye better clean these cells, boy. Then report to me quarters. Else you'll be finding yerself a full part of me body!"
Nate looks to the pirate captain. The man even older now, looking like someone's muscular dad with built body covered in a mix of red and grey hairs. The sailor walking out of the hallway, as Nate rushes to the thankfully clean bars. Able to see his own reflection, the stern warrior now a smooth cabin boy. Boyish and thin, hair cut short and beard cleanly shaved. He had to be barely an adult now, and barely able to mimic even a fraction of his former strength. His hands roaming his body, stopping at his new bubble butt and giving it a grasp. This isn't going to be fun to have around pirates...
Past the bars. The hall and cell was stained in spunk, and completely empty. None of the other prisoners able to resist the crews influence, and becoming older pirates, eager to please their captain and spread his curse. While Nate at least managed to retain his mind, fighting off lingering thoughts as he wonders what he should do.
The captain has commanded him to clean every inch of this room. he knows he'll be punished if he doesn't do it, and he doubts there's any hope of escape if he just runs out of this prison. But can he really obey the captain? Cleaning this room is one thing, but who knows what he plans to do when he's alone again with Nate.
