Mission 6: Epilogue 

"Excellent work," Savas said, bowing his head and placing one hand on his chest. 

"Thank you, sir, " Unsal replied, bowing in turn.

"That concludes your mission. You may return to your quarters until we return home. We are scheduled to depart once the last team reports back. We are expecting them any solar day now." 

"Understood," Unsal stepped toward the door of the meeting room, but stopped just before reaching it. His heart was pounding heavily. "Savas?" He said, getting the commander's attention. May I make an informal request?" 

Savas relaxed his posture and walked over to him. With the mission concluded their formal chain of command was less necessary for which both of them were relieved. "Of course, old friend." 

"Could you…meet me in my quarters once you finish with today's work?"

"You're personal quarters?" Savas asked, confused. While all life aboard their mothership was monitored, the personal quarters for each crewmember was not. Privacy was taken very seriously for all personnel, civilian or military alike. Though not forbidden, for any Xipen to visit another’s quarters was highly irregular.

"As long as you have time, I understand you are very busy." Unsal maintained an innocent tone in his voice. He didn't want to scare Savas away with a more forward request." 

"I…should be able to before the day ends. It will be after the evening meal." 

Unsal smiled and nodded. "I shall wait for you then. Thank you." Bowing once more Unsal turned around and exited the room. He could barely contain his excitement as he returned to the residential wing. His friend and commander would soon become his mate. Just thinking about the potential of their activities to come caused his cock to twitch and his cloaca to become wet. 
"Soon, " he thought, calming his nerves. "Soon."

… … 

A chime rang through the comms system in Unsal's quarters. Each of the scientists had a respectable few rooms to themselves including a sitting area, a small bathroom, and a bed wide enough for 2 or 3 Xipen to share in case of an emergency. Unsal opened his chamber door to find Savas out of his formal attire and (like himself) wearing the single piece casual jumpsuit given to each of the crewmembers. It was similar to the everyday attire which Unsal wore on missions, except the fabric stopped at the ankles leaving their feet exposed. 

Unsal was quick to notice Savas' dick pressed tightly against his body. Their casual suits didn't leave much up to the imagination. He invited his commander inside and shut the door behind him. Even from behind, he could see every curve of Savas' body. Ever since returning from the planet, Unsal took every opportunity to admire his form. Though before mating with the various creatures he never thought of his friend's body like that, it was now all he could focus on.

"So…what made you invite me here of all places?" Savas asked, curiously. 

"Have you considered what you will do when we return home?" Unsal asked. "I know it's expected that we find a partner once our service ends, but have you considered anyone in particular." 

Savas closed his eyes and folded his arms. "To be honest I haven't given it much thought. Things are so busy around here it's hard to find the time." Opening one eye he glanced at Unsal. "Why did you have someone in mind?" 

Unsal smiled and stepped closer to him. "I actually did." Savas relaxed his arms and opened his other eye, feeling Unsal step into his space. "I always thought it would be someone who appeared at the right time, but there's also someone who has been here from the beginning." 

"U…Unsal are you asking me to…?" Savas stuttered nervously as he saw the hunger in his friend's eyes. 

Unsal nodded and placed his hands on Savas' shoulders. "Savas…will you be my mate?" 

The commander blushed and his dick involuntarily twitched. He couldn't believe that his long-time friend had changed so much from his missions. The once shy Xipen was asking to be his partner, and the confidence in his voice was extremely arousing. 
"I…I'm not sure what to say, Unsal. This is all so sudden. Plus I've never actually…ah!" Savas gasped as Unsal ran his right fingertips down from his shoulders to his dick. Savas was stunned as Unsal traced the outline on his suit. The light touch of another Xipen's fingers sent a tingling sensation through his whole body.

"Say yes, old friend," Unsal said seductively, "and let me show you what our species has been missing out on for centuries." 

Savas nodded, mesmerized by Unsal's gaze. "What do I need to do?"

"Hmmmm," Unsal hummed, running his left hand to Savas zipper and sliding his right to the base of the Xipen's dick. "Just relax for now." Unsal slowly pulled his commander's zipper down revealing his grey chest. Again grazing lightly with his fingertips, he eased the suit off of Savas' shoulders revealing his stiff Xipen cock. Just like his own, Savas' member was nearly the length of his entire torso. It stood proudly, parallel with his body. 
"Beautiful," Unsal whispered, and he grasped the length with both hands. "Pull off your suit the rest of the way for me. I'll get you ready while you do." 

"Ready?" Savas asked, letting his suit fall to the floor. "For wh…aaaaah!" He let out a long moan as Unsal began pumping his hands up and down. Savas stepped out of the leg holes as Unsal stroked him. The Xipen was surprised how eager his friend was. It seemed his missions had freed up any inhibitions he once had. Savas himself was still unfamiliar with any kind of contact beyond self gratification, but knew Unsal could guide him. 
"Ah, that feels…so good Unsal," Savas said, his breathing increasing.

Unsal stepped closer pressing Savas' cock against his own (which was still covered by his suit). Releasing his right hand, Unsal unzipped his suit and pulled it off of his body. His dripping cock slapped against Savas' chest, painting him with precum. 
"We're really lucky, you know. Our bodies were designed to feel the best pleasures in the universe." 

"U…Unsal?" Savas stuttered, as their long members pressed together. The pleasure he was feeling was rising exponentially every second. He had no idea that the touch of another Xipen's body could feel so good. He quickly let go of any remaining hesitation, and accepted his friend as his mate. 
"Unsal, I…"

"Shhhh," Unsal hushed him, raising one finger to his commander's lips. He then stepped back and took Savas by the hand. Unsal led him to his bed. Laying on his back Unsal raised his legs presenting his cloaca to Savas. 
"Come explore me, sir," he said, inviting Savas over. 

Savas' cock twitched instinctively, shooting out a stream of precum onto Unsal's chest. Unsal chuckled as his commander approached him and grabbed his hips. Lifting him upward slightly, the Xipen rubbed his long shaft back and forth on Unsal's hole. Savas was fixated on Unsal's cloaca. His mouth gaped open. He was mesmerized but moved almost instinctively. Something dormant in his subconscious was driving his body to move on its own, despite his brain only being able to think of how strange it was to be seeing his friend's nude form for the first time. 
"Are we really doing this, Unsal?"

Unsal nodded and smiled looking into Savas' eyes. "Don't be afraid, old friend. It's going to feel amazing."

"O…ok," Savas replied, and pushed his tip into Unsal.

"AH!" they both gasped. 
It was like a light switch turned on in Savas' brain, and he followed up the initial penetration with a firm and aggressive thrust. Unsal gasped louder as his cloaca stretched to accommodate his first Xipen cock. His body quivered, feeling the smooth skin side in and out of him. Like a piston, Savas began pumping in and out, his breathing became heavy. 
Unsal couldn't believe how perfect Savas' cock felt. He had mated with so many different creatures on his missions, but none were so perfectly made for his cloaca. Like his own, Savas' cock was long, but not too thick. The way his own cloaca was able to clasp around it, made sure they both gave and received huge amounts of pleasure. He could feel every inch of it, and every drop of precum that hit his insides. 

"Oh, Xipas! Yes! Breed me, Savas!" Unsal grunted.

Savas was intoxicated by the pleasures he was feeling. No amount of self gratification had ever felt this good! Having his entire length squeezed by his friend's cloaca sent continuous waves of pleasure through his whole body. His own cloaca began dripping down his legs, with each passing moment. The combination of his own heat beginning to commence paired with the thrusts in and out of Unsal, was quickly pushing him closer to climax. 
"U…Unsal…I'm getting close." 

"Breed me, Savas! Fill me with your seed!" 

"Aargh!" Savas grunted and slammed his hips hard against Unsal. His cock throbbed, releasing a monstrous load of cum into his fellow Xipen. Unsal clenched his cloaca tightly, holding his partner in place as cum splashed deep inside of him. With eyes wide, he took in every last drop of Savas' precious cum. Flexing his internal muscles, he allowed himself to absorb the cum and begin the process of reproduction in his body for the first time. 

With Savas milked dry, Unsal relaxed his cloaca, letting his partner pull out. 
SHLOOOP! 
"AH!" Unsal gasped as Savas' cock slipped out. A slight dribble of residual cum and his own cloacal fluids ran onto the bed. Savas collapsed forward onto him in exhaustion. 

"Oh Xipas!" Savas gasped, catching his breath. "That was unreal! Why did our species ever stop doing this!?"

"Who knows," Unsal replied with a long exhale. "But I'm so glad we did it." 

"Me too old friend," Savas said, snuggling up with Unsal. "Thanks for choosing me as your mate." 

The two laid together for what seemed like ages, both fully satisfied by each other's bodies. Though he wanted to return the favor and breed Savas (especially considering how much juice was still leaking out of his virgin cloaca), Unsal was more than happy to have been the one who received it. After being filled over and over again by all sorts of alien creatures, he finally had found the best mate of all. Unsal and Savas would continue mating nightly until their return. Their bond grew from childhood friends, into lovers on the long journey home. 

Once the two Xipen found themselves on familiar soil, they continued mating almost daily. Armed with new genetic information, the two would create a wave of new offspring pure enough to save their dying race. Even after their offspring grew up, they continued breeding each other as much as possible and their dedication to one another became legendary.
