Mission 4.5 - Sweet Relief 

"Not a problem, you've more than earned the time off. We'll check back in two days."

"Thank you sir," Unsal replied. "Signing off."

Unsal sighed in relief as he sat back in his chair. He was barely able to sit through the video call without ripping his suit off. His whole body ached with desire. Even at night as he slept, he would dream of being bred by the creatures from his previous missions. He has been waking up to precum soaked sheets night after night, and he now needed some time to work off the pent up lust he was feeling. 
Despite needing the time to recuperate after his mission with the goat, he had decided to wait before asking for a break. After another 3 missions he just couldn't stand it anymore and decided it was time to request a pause before the last mission on his schedule. Two days was what he was given by central command and he planned on using every moment it to his advantage. Standing from his chair in front of the comms system, he made his way to the sleeping quarters. Quickly, Unsal unzipped his suit and tossed it to the side. His long Xipen cock was already hard, standing straight up against his body. His cloaca was also wet and leaking clear liquid down his thighs. His body had become conditioned from recent missions to expect penetration almost immediately after undressing. 

Laying on his bed he held his cock upright with his left hand and began stroking it slowly with his right. After so many missions he found that arousal was no longer a chore like it one was. He wasn’t sure if it was due to his previous inexperience or his race's genetic degradation that kept him from experiencing the pleasure from his body for so long. Whatever the reason those days were all in the past. Even the gentle rubbing he was doing was enough to drive him wild. Yet despite the spikes of pleasure for each stroke, he still found himself desiring something more…something inside of him. 

He reached his left hand down between his legs. With two fingers he rubbed across his cloaca spreading his natural juices around. His right hand moved up his shaft until he was squeezing his tip, matching rhythm with his left. 
"Ah," Unsal gasped. "That feels good." Increasing the pressure on his tip, he pressed two of his left fingers together and plunged them into his cloaca. 
"Oh, YES!" He exclaimed, as he pumped in and out of himself. Quickly he located his prostate and began pressing against it with each inward motion. "That's the spot!" 

As his breathing increased he also increased the speed of his movements. His cock twitched, shooting out long streams of precum which landed on his chest. 
"Oh Xipas, if only I could…" Suddenly he stopped and pulled out his fingers. He sat up and looked up and down the length of his shaft. "Wait, why couldn't I?" 

Turning over onto his chest, he lifted himself up to his hands and knees. His cock was still mostly hard, but the suddenmotor in self pleasure had caused it to soften just a little. It was enough for Unsal to be able to bend it around freely. 
"Alright now, nice and slow." With his right hand he began guiding his dick in a counterclockwise motion. Rotating it around little by little, he eventually managed to turn it so that it was pointing out behind him. Again working slowly, with the now semi-hard shaft, he bent it back until his tip touched against his cloaca. He gasped feeling his own cock at the entrance. 

"Oh wow! Why didn't I try this before? This is gonna be amazing."
Continuing to guide himself with one hand, Unsal's cock slipped inside of his own cloaca and immediately pulsed, shooting out a stream of precum. His eyes lit up as he felt his own juices splash to the back of his body. The sensation was incredible! A shiver trailed up his spine and he began pumping his shaft in and out with his hands. 

"Ah, ah," Unsal moaned, feeling pleasure both on his cock and inside his hole. The feeling combined the pleasures of masturbating and being bred at the same time. Quickly he increased his speed. His breathing increased further and his moans grew louder. 

"M…more! I gotta have more!" He reached to the base of his length and pushed harder, allowing his cock to slip further inside himself. "Ah, yes!" Unsal exclaimed, feeling his cloaca stretch. He now had half of his long Xipen cock buried inside. He couldn't believe he was making himself feel so good. 

His cock squirted out more and more precum as time went on. He could actually begin feeling himself becoming a little full from it. There was so much more than when he would just be on the receiving end. Is this what it was like to breed with another of his species? Would they leak as much as he was? Part of him wished Savas was there with him, being the one who was making him feel so good. 
"I…I bet he's just like me." Unsal grunted, thinking of his commander. "I think I want him…I…oh Xipas! I want him to breed me!" His cock throbbed releasing a monstrous load of cum deep inside himself. The hot Xipen seed splashed together with the precum filling him to the brim. His stomach bulged out, accommodating for the epic volume of thick liquid. Unsal shivered as the cum began leaking around his cock, unable to be held back inside. He could feel the hot liquid sliding down his legs as his cock began to soften. 

Eventually Unsal let himself relax and his dick flopped out. Collapsing onto his stomach he let himself rest with his shrinking member backwards between his legs. His cloaca gaped open, and his cum continued leaking out across his shaft and sheets. His body was wrecked from the pleasure of violating and breeding himself. With every part of his body now completely satisfied he found himself thinking about his commander. He was completely awestruck that his mind had gone to Savas as a potential lover. He wasn’t sure why, but suddenly he was no longer thinking about the creatures of his mission, but his friend and commander. 
"Do I really want him?" Unsal thought. "I mean with his tactical prowess and my research skills our offspring would be extremely valued. Yet, I don't think I care about that. I want…no…I NEED him. I need him to breed me. I need to feel him deep inside. I need to be filled." 

Reaching behind himself, Unsal grasped his soft dick and once again guided it to his cloaca. With Savas still on his mind, he pushed his length inside one more. Gasping he pumped his cock in and out until he was hard once more. The tension of his full erection stretched him open and once again shot waves of pleasure through his body. 
"Oh, Savas," he mumbled, "When this mission is over I'm gonna show you just how much fun breeding is."

Unsal continued pumping himself with cum over and over for the rest of that day. Each time he imagined Savas being the one who was breeding him, only adding to his lustful desires. Perhaps this was the real point of the mission. Not just to collect genetic material, but also to learn how to show affection and once again let their species remember how to make love.
