The Starduster snaked its way through the small asteroid belt, carefully avoiding any collisions. The autopilot on the ship was doing a wonderful job not hitting any obstacles. If the two occupants were paying any attention to where they were they may marvel at their vessel's ability to change directions like this. But they were elsewhere, busy in the ship's exercise room. The master of the spaceship, a giant green alien man called Khorganak, was reaching the end of his intense morning workout. His giant muscles bulged as he was curling massive metal dumbbells that on the planet Earth would weigh over 5,000 pounds each! To him though, they were nothing. His naked green body was drenched in sweat and he was tired from his morning session. He was slowing down, feeling the burn everywhere and the soft pair of lips touching his huge alien cock.
In front of him, standing only about half his height, his traveling companion and lover Christine, the last human being in existence, stood sucking on his rock hard cock. In the time they had been traveling together, this had been a routine that the two had worked out. For Khorganak, his workouts were much more effective and he got much more energy and endurance if she was there to provide him with a release. For Christine, she was simply able to indulge her love for sucking the giant green alien's massive cock. While at first during their time together she had been nervous and a bit disturbed at sexual relations with Khorganak, she was now completely comfortable with it. To be honest, he was the best lover she had ever had and she had grown to love the idea that she got to fuck an alien, making the sex that much more intense for her.
As Khorganak pumped iron, his cock was throbbing inside Christine's mouth. He dripped the sweet-tasting precum she had grown practically addicted to in her mouth and she swallowed it all down. She knew that it would only be a few more pumps of the dumbbells before he would explode with a powerful orgasm and she prepared herself, wrapping one hand around the thick green shaft of his alien dick. Sure enough, he dropped his arms to his side as he came hard, quickly filling her mouth with his warm, pink cum. But he came faster than Christine could swallow, so she pulled the head of his cock out of her mouth and let him shoot his massive load all over her naked body. Soon she was drenched in it as Khorganak, spent from his workout, let the weights fall to the floor.
The two made their way to the ship's bathroom as Khorganak slipped into the tub full of warm, rejuvenating water that always healed his body after a long workout. Christine got into the shower, washing the sticky alien cum off her human body. She felt some of it had gotten into her long brown hair as well, so she began to lather it in shampoo since it had been a few days since she really washed it too. As she showered, Khorganak turned while soaking in the tub and began to talk to her.
"I'd say that's the longest one we've had babe, wouldn't you?"
"Probably. I mean this time you lasted over an hour and a half."
"Yeah and you didn't take a single break either, just sucking the whole time."
"Well honey, I guess you can say that I was... motivated."
The two of them laughed at Christine's remark, but she knew that there was some truth to it. She really loved pleasing Khorganak in that way. Plus it was remarkable that she had spent all that time giving him a blowjob and did not take a break. While motivation was a factor, she knew that in the time she had been on the Starduster, ever since she had left Earth, she had much more energy for activities like that. Maybe being out in space was doing her good. Or maybe Khorganak had been right that humans back on Earth had been limited by the confines of what the planet could give them. No way to tell that now since the Earth was gone, destroyed and Christine was the only survivor. But she didn't dwell on that thought much anymore. Instead, now all cleaned up, she got out of the shower and lowered herself into Khorganak's bath, sitting on his lap.
"Well," he told her, "your motivation is much appreciated." He bent down and the two shared a passionate kiss as they relaxed in the warm bath water. It had taken some time together before they shared a kiss (much longer than the couple hours of knowing each other before Khorganak first had sex with the Earth woman), but they both enjoyed the feeling of the other's tongue (or in his case tongues) in their mouth. They made out in the water for a while, their hands exploring the other's body.
"Do you think we have time to..." Christine started before being interrupted by an alert from the ship's computer.
"Afraid not," Khorganak told her as he rose from the tub. "Looks like we're getting ready to land on Loe." He took a couple seconds under the drying machine before heading to the ship's control room. Chrsitine sat in the bath for another minute before draining the tub and drying off, joining the giant alien man at the controls as he landed the ship on the planet Loe.
The Starduster touched down softly on the planet's surface. The protective shields that covered the windows during space travel and the main hatchway opened. Khroganak and Christine made their way out of the ship and down to the ground. Christine looked around at the shipyard they had landed in and would be their home for the next few days as they visited Loe. There was a celebration there that Khorgnank told her was a popular destination for many travelers. It only occurred once every 1,000 years on Loe, which converted to nearly 1,900 years back on Earth. He was right that it was popular, as every other space was occupied by other alien crafts of varying designs. Looks like she was in for meeting many new people from all sorts of planets.
The two left the Starduster for the time being and began to walk around the city of Loe, the seat of government on the planet. Christine had been to a few different planets in the time she had been traveling with Khorganak and found something interesting on each one. Here, the most interesting thing was that everything native to the planet was royal blue. All the buildings, signs, streets, plant life, even the people were all the color blue. She asked Khorganak about this and he confirmed that everything on Loe was blue. If something wasn't that color, then it was alien to the planet. The sea of blue being broken up by dots of many colors showed her the true number of visitors on Loe right now.
There were many different races of aliens that passed Khorganak and Christine as they walked the streets. But Christine noticed that they all shared one common characteristic: not one of them had on a stitch of clothing. She looked down at her own naked body and thought back to when she had first been taken aboard the Starduster and Khorganak had told her that humans were just about the only species out there that wore clothes. At first she thought he was maybe tricking her so he'd just get to look at her naked whenever he wanted but as he began taking her to different worlds, she saw he had been telling the truth. That had been the thing that took getting used to the most for her; being nude all the time in front of everyone else who also went naked. It didn't bother her anymore though, she was totally comfortable with it and actually found it free and relaxing to not wear clothes. She now proudly walked down the street with her tanned body on full display, her big breasts, perfect ass and gorgeous figure seen by everyone else they encountered.
The two entered a restaurant that wasn't too crowded and sat down to order. Khorganak ordered food and drinks for the two of them, as his universal translator implanted in his ear allowed him to be able to understand and be understood by anyone they encountered. Christine didn't have one yet, as he had been unsuccessful so far as creating one on a frequency that would work for her body. He could translate things for her though as he had learned to speak English from her during their travels and all the time the two would spend alone flying on the Starduster, and she had picked up some of his native language too and hoped to learn more soon. The two chatted as they waited for their food.
"You know," Christine began, "I think I would go crazy if I was on a world where everything and everyone was the same color."
"You make a point," Khorganak said, "but I guess they have no choice in it."
"Do you know why everything is blue?"
"The last time I was here, some of the people told me that it was something in their atmosphere. A compound unknown that pollutes everything and makes it this color."
"So you're saying if we stay here, we're gonna turn blue too?"
Khorganak laughed as he offered his reply. "No, we won't. They told me that the color change wouldn't be noticed on a non-native unless we stayed here at least ten years."
"Oh good. I'm happy just the way I am."
Their food was delivered by one of the people of Loe. Christine got a good look for the first time at one of the planet's natives. The waiter was blue like everything else on the world. They were a little shorter than Christine's own 5'1" but quite skinnier. They had four arms and four legs, all pretty skinny. Their bodies were completely hairless and free of any signs of gender like breasts and genitals. All three of their eyes were blue like everything else. The server left the two travelers to eat their meal.
Christine drank the blue cocktail that had been placed in front of her. It wasn't that bad but she wished it was a bit sweeter. She ate the plate of blue meat and veggies in front of her, finding that it was pretty good. As they ate, she asked more of the people from Khorganak.
