Captain Mariska Holmes shuddered as she came for what seemed like the tenth time. She was sitting in the pillowy gel of her action couch, a thick rod of the translucent green substance gently fucking her sopping cunt. Two thin green tendrils were attached to her leaking nipples, sucking up the thick cream that was pouring from them. A long ago encounter with a Praxian Slobber Hound had thrown her hormones seriously out of whack, necessitating frequent milkings. Not that she minded. One of the first things she'd done upon taking command of the Astarte had been reprogramming her couch to take care of her more private needs. Adding a milking routine had been simple. Changing the parameters of an action couch was officially frowned upon, but the practice was rampant in the fleet.
She had rolled over and spread her ass cheeks, the gel cock just starting to push in to her rosebud, when the com set in her ear beeped.
"This is First Mate Yralla, requesting your presence on the bridge. Captain to the bridge please."
Mariska shook her head in frustration, and reached over to the control panel to turn off the stress relief subroutine. Her assfucking would have to wait. She caught a glimpse of herself in the mirror as she stood, and paused for a moment to admire what she saw. Thick black hair flowed in waves past her shoulders, framing a face that was both strong and sensual. She had a trim and athletic figure, with long legs, a flat muscular stomach, and a firm round ass. The mountainous globes of her breasts didn't seem to fit in with the rest of her slender form, gravity defying mounds that many assumed were fake, but that she could prove were not. Mariska smiled at her reflection, a thin sheen of sweat and the glow of many orgasms making her look alive and energetic. A thin trickle of milk still dripped from her dark nipples and ran down her olive skin. She swept some up with a fingertip and brought it to her lips, savoring it's sweet taste.
She glanced at the clock mounted on the wall of her private cabin and decided she better go and see what was happening. A gold chain encircled her waist, and Mariska reached down and touched one link in particular. Nanofabric began flowing from the chain like oil, painting her skin in the space black of a captain in the Galactic Council Fleet. In seconds the ship suit had coated her from feet to neck, covering everything but hiding nothing. The twin gold stars of a warship commander bloomed on her collar as she walked out of her cabin.
"Captain on deck!" First Mate Yralla came to attention as Mariska entered the room.
"Carry on." Mariska made her way to the captain's couch, the gel conforming to her shape. Unlike the one in her cabin, this couch didn't have any extra functions. It was simply there to protect her body during any hard maneuvering. "Yralla, what's the situation?"
She had to smile as her first mate approached. The GCF Astarte was rare in having an almost entirely female crew. The first mate was the only exception. Yralla was a Vollarian, a species from the Sirius system. From the waist up she looked exceptionally female, despite her blue skin, bald head, and purple eyes. Her face, lips, even her breasts would have been the envy of any human woman. But once you let your eyes drift a little lower you would see why she didn't quite qualify as female. The thick length of her cock swung between her legs, covered in the same nanofabric as the rest of the crew, this time in red. Vollarians were one of the rare species that were true hermaphrodites. At first glance, Vollarians resembled human pornstars, but a closer inspection would reveal that every Vollarian had both sets of genitals. It had been quite a shock when humans had first made contact. The Vollarian's complete lack of any nudity or sexual taboos had also taken some getting used to. Luckily, their attitudes towards sex seemed to rub off on most of the humans that they met, meaning that both species existed in general harmony.
Mariska took the time to admire Yralla's pussy-wrecker of a cock. It hung nearly to her knees, and the thin nanofabric did nothing to hide the pulsing veins running along it's length or the wide flat head at it's tip. One of her proudest moments had come during a drunken shore leave on some backwater planet, when she'd manage to stuff Yralla'a entire cock down her throat. Her jaw had been sore for days, but it was worth it. Mariska saw a twinkle in Yralla's eyes when she looked up. She was probably thinking of the same event.
But, there was work to be done. "Ma'am, we've received a distress call from the planet Lornu, in Sector B1a."
Mariska nodded. "Details?"
Yralla looked over at the duty com officer, Mika Taggart. She stood, breasts jiggling under her dark green ship suit. "Ma'am, apparently a convent has come under some sort of attack. The Holy Sisterhood of the Goddess Naira. We are the closest GCF asset. It's not a very developed planet, and the local authorities can't handle the problem."
Yralla snorted. "Nairans," she said, disdain in her voice.
Mariska raised an eyebrow. "What's wrong with Nairans?"
"They're prudes. Denying themselves in worship of their goddess of purity." Yralla shook her head. "It's unnatural."
"Well, unnatural or not we have a duty to go and investigate. Helm, how long to Lornu?"
Lydia Montrose, the fourth and final crew member on the bridge, consulted her console. "Approximately 2 hours by hyperdrive, Ma'am."
Mariska nodded. "Very good. Yralla, you have the bridge. I'll be in my cabin. Please alert me when we're fifteen minutes out." She stood and departed the bridge, her loins already tingling in anticipation of resuming her interrupted sodomy.
2 hours later she was back on the bridge, watching on the main screen as the blue and green orb of Lornu passed below them.
Mariska turned to her com officer. "Any further transmissions from the convent?"
Mika shook her head, tossing her blonde locks. "No Ma'am, we received the standard transmission from Orbital Traffic Control in the main settlement when we arrived, but nothing is being broadcast from the convent. However, our scanners are picking up an active receiver down there. If someone is on the other end we should be able to talk to them."
"Very well, patch us in."
Mika began working with her console. "We're connected. It should be coming on the main screen now."
The picture on the screen switched to a young women, a human. She was wearing some sort of robe. Her clothes were torn, but other than that she looked to be in good condition. Though she was obviously terrified. "Hello? Is someone there? I can't see you."
"This is Captain Mariska Holmes, of the GCF warship Astarte. We received a distress signal from this location. What is your situation?"
The girl's face brightened with relief. "Oh thank you blessed Naira! I didn't know if the signal had gone out. Please, you have to help. The other sisters, they've become...corrupted. Please!" Relief was starting to give way to panic.
