It'd been a week since the Matroviran slaves overthrew their Human captors on the way to a new star system. It happened swiftly and ended before the day was over. The ship they were all on fell under their control and the Matrovians imprisoned the Humans in their former cells. They separated the men and women, keeping the men in individual cells away from everyone else. Since the ship was part of a military expedition, there were few children. Those few were left with the women to care for them.
Kenn was shackled to the wall of his cell. It was small, but just big enough to have a bed designed for Matrovians. He wished he could lie down on it instead of being forced to stand naked. It could have been worse. The Matrovirans looked human but were larger and stronger in every way. They could've just executed him, but instead they kept him alive. Every day, a guard would come by and feed him stale bread and water that had a weird taste.
Today however, the guard didn't come with food. Instead, she came in with a shorter Matroviran. Well short for their kind. She was a couple centimeters taller than him. The guard grinned before leaving her alone with him.
"My name's Carla," she said, "nice to meet you."
They examined each other, her eyes mostly focusing between his legs. She wore a military uniform, though since they were designed for humans, it looked tight around her. Hugging her larger proportions and revealing a lot more than they were designed to. He knew she was his captor, but he couldn't deny how attractive she looked.
"I guess you like what you see?" She smiled down at him. He hadn't noticed he was getting hard. "I guess we are a bit curvier than you're used to."
She undid the top button of her uniform, allowing her large breasts to burst free. Kenn glanced away awkwardly. Finding her attractive was one thing, but he was also married. Carla stepped in close enough that her nipples gently rubbed against him.
"Looks like someone's a bit shy." Her hands reached up to play with his nipples as she gazed into his eyes. "Never been with a woman before?"
His breath caught as a hand went down and gripped his shaft. She gave it a few strokes until it was fully erect before dropping to her knees. Kenn was too shocked to speak. His shackles prevented him from stopping her. Carla slowly stroked his dick with one hand and fondled his balls with the other. He looked down to see her studying his genitals rather than trying to get him off. Though he swore he could see jealousy in her eyes as she touched him.
"I'm shocked honestly. With a cock this big, I'm sure you'd have any woman dropping to their knees to suck it. I know if mine was this big, I could bang anyone."
Softly, she kissed the tip of his dick before giving it a lick. She ran her tongue up and down it, lubricating every inch of it. When she was satisfied, she stuck the tip in. Her head bobbed on it, going deeper and deeper. The hand that fondled his balls moved down to rub between her legs. Her uniform was so tight that he could see the shape of her dick. It was small, even by human standards.
Kenn pulled against his shackles when he was far enough in to gag her. Carla stopped to look up at him. "I have been with a woman before."
Slowly, she pulled his dick out with a pop that made his knees weak. "Really? But you squirm so much it's like I'm sucking off a virgin."
He struggled to speak as she continued licking and stroking and kissing his length. "I'm m-married."
Carla smiled up at him smugly but didn't say anything. Instead, she started sucking with more fervor. This time using a hand to stroke whatever she couldn't fit in her mouth. She gagged a few times before he couldn't hold back anymore and came down her throat. It was an odd sensation.
"Mmm." It wasn't enough to satisfy her though. She backed off but stroked it with both hands to keep him hard. "I bet she just married you for this big guy. Don't run across cock this big too often."
Kenn moaned awkwardly as she started licking again. "I guess that was p-part of it. She's always been a b-bit of a size q-queen."
"Oh really now?" She smiled with a twisted grin before sucking again. This time getting him off in half the time. "I'll keep that in mind for later."
"What do y-" Kenn cut off when she started stroking again. She pouted when she couldn't keep it hard anymore. He felt drained after cumming twice so quickly. One of her hands moved up and forced two fingers into his mouth. She slid them in an out a few times, rubbing his tongue between them, until they were coated in spit.
"I need you to relax for a moment."
"What?"
She answered with one of those fingers up his ass. It wiggled around inside him, making him squirm. She started sliding it slowly in and out as her fingertip pressed against his prostate. Kenn moaned and his dick became hard again.
Carla grinned and sucked eagerly at it. She mirrored her sucking with her finger thrusting. When his dick went farther in, so did her finger. Kenn had never felt this kind of pleasure before. He only lasted a minute before blowing another load down her throat. She barely gave him a break before sliding another finger in, stretching him wide open. It made him immediately blow an unexpected load across her face.
"Guess you really liked that, huh?" She laughed and licked it off.
He couldn't speak. Every thrust of her fingers made him moan like an animal in heat. She suddenly spread her fingers apart, stretching his hole further. His dick twitched up at her, nearly cumming again. When he didn't, she used a lone finger to ever so gently rub the sensitive skin beneath the head. It made him shoot another load into her open mouth.
After that, Carla stood up. She seemed taller than when she first walked in the cell. At least a foot taller. As she watched him pant heavily, she started playing with his nipples again. "You know, I'm starting to think you liked me playing with your asshole more than sucking your cock."
"No, It's not like that."
"It's not?"
She sauntered her way behind him, her hands nonchalantly trailing around his waist to grope his ass cheeks. Something hard slipped between them and prodded his asshole. Her dick felt bigger than it had looked earlier. "But you came so much faster with my fingers."
"N-no." He lied.
Carla leaned against him; her large breasts pressed against his back. Her dick rubbed between his cheeks. It was definitely bigger now. "I don't believe you. I think you actually crave it."
His knees buckled as the pressure built against his little hole until it gave way to her dick. It was easier than he expected since she used her fingers to loosen him up. She slid it deeper and deeper, ignoring his desperate cries until she was as deep as she could go. Kenn's dick throbbed with pleasure as her dick pushed against his prostate. Some cum dribbled out.
