The year is 2354. It’s been a month since Osa and her dog, Kaabo, dropped off her brother, Adunbi, back on Earth, and the two are now cruising in her shuttle. Her data cylinder is in one of the computer ports on the twin pilot control panels, and everything is powered up, on automatic, and traveling at speeds of 67061662 mph, or 0.1 light speed of light.
She has two biosuits designed to fit like a second skin but are still comfortable. They can recycle air and body fluids and allow for the removal of solid waste. They are resistant to low-force impacts and punctures, and they help regulate body temperature in warm and cool environments. The suits open and close from the side, and the seam is completely undetectable when sealed.
The shuttle has one inertial compensator but no real artificial gravity. She expects the trip to take about 180 hours, give or take a few minutes, so Osa has stripped out of her bio-suit and is spending the majority of the trip naked. With only one bed on the shuttle and an open shower, things get pretty cozy with Osa and Kaabo.
Osa is face down and ass up on the bed, with Kaabo mounting her from behind. His cock is 22 cm deep in her cunny, pressing against her A-spot and into her cervix a couple of millimeters, and his knot is stuck just inside the opening to her cunny, pressing on her G-spot. Her vagina is contracting and massaging his cock as he fucks her and pumps her womb full of his sperm.
Then warning lights and alarms start flashing. Unable to pull herself free from the massive dog knot wedged in her cunny, Osa is only able to press the emergency button next to the bed that encloses the bed in a safety bubble that expands and wraps around all those inside, locking them in place for the impact. Every shudder of the ship sends ripples through the bed that shakes Osa and Kaabo, causing the tip of Kaabo’s cock to slip several more millimeters into Osa, causing her to climax continuously, squeezing the dog cock lodged in her cunny and causing him to keep pumping close to 400 ml of canine sperm into her womb.
After the shuttle comes to a stop and the protective bubble recedes from the bed, Kaabo can dismount and withdraw from Osa. Osa’s uterus is so full of dog sperm that her stomach has the slight swell of a 14-week pregnancy.
Putting on one of her biosuits, Osa takes a hand sensor and goes outside to figure out how much damage was done and what kind of planet she’s on.
Around the crashed shuttle are nothing but tall grass-like plants as far as Osa can see. Suit sensors indicate multiple outer hull breaches, but the inner hull remains intact. The shuttle crashed after being hit by a micrometeor swarm. Scans indicate a missing communications antenna and a damaged navigational array. The antenna is detected 14 kilometers from the ship. Osa says to herself, “Fuck me. No, that’s what got me into this mess. Damn it.” And finally, the atmosphere is close to Earth’s, with less nitrogen, less oxygen, more carbon dioxide, more hydrogen dioxide, and a higher atmospheric pressure and gravity. The planet would be classified as a terrestrial/ocean super-Earth. The computer suggests that Osa can survive in the atmosphere for approximately 75 minutes before falling unconscious and recommends a time of less than 45 minutes to be safe.
Osa attempts to repair the ship with guidance from the computer. She begins by patching the holes in the outer hull. That takes the better part of an hour. Then Osa goes inside, peels her biosuit halfway down, and uses parts from the damaged primary navigation system to get the auxiliary navigation system working.
Tired, Osa rummages through her strewn-about supplies, straightening up a bit as she goes, until she finds a packaged food ration. She shares half the ration with Kaabo. After that brief rest and meal, Osa feels refreshed and is ready to go collect the missing communications antenna.
Preparing for the long walk, Osa fastened up her bio-suite and swapped out her tank of contained oxygen for a bio-scrubber that filters O₂ out of the atmosphere and CO₂ from inside the suit. She equips a 45 cm blade to cut through the tall grass and a taser pistol in case she encounters any aggressive life forms. She programs her directional locator and heads out.
It’s a long walk; it takes Osa over 3 hours to reach the location. However, when she reaches the designated marker point, the antenna is not there. She scans again and finds that it is 3 kilometers to the right of her location. Looking in that direction, she sees thicker, taller plants in the distance. Not like trees, but more like softer woody stalks.
As Osa follows the signal, she notices drag marks on the ground. And that the stocks are roughly 10 meters tall and covered in mossy growth and vines. She pauses a few meters away from the cluster of shoots and pulls out her taser. Osa says to herself, “Hell no, I’m not going in there. Computer! Do you read?” “Affirmative.” “Scan my location, and set autopilot to come to me.” “Affirmative.”
As Osa takes a few steps back to increase her safety zone. Several vine-like objects shoot out of the cluster of vegetation, wrapping around Osa’s legs, arms, waist, and neck. Osa tries to escape the grappling tendrils but only succeeds in falling on her back.
The vines start pulling Osa towards the cluster of stalks, and despite her struggles, Osa’s resistance only caused the tendrils to grip tighter around her and pull her faster towards the thicket.
As she reaches the thick growth of plants, Osa can grab onto one of the sturdier shoots that rise from the ground, but she’s unable to hold on for long as the tendrils pull her into the dark shrouded grove.
Near what she thinks is the center of the overgrowth, Osa is held immobile. Looking around, she can barely make out the silhouette of her missing communications antenna.
Then Osa feels something touching the outside of her biosuit, like it’s exploring her, trying to figure out what she is. Maybe trying to figure out if she’s food or something else. As the feeler is exploring her wrist controls, it flips the switch that turns on the lights on the top and sides of her helmet, illuminating the thicket patch and exposing the creature that lives in it.
What she sees is a mass of plant matter that resembles a jellyfish suspended from the surrounding stalks. Inside the central area, Osa can see small creatures, probably this planet’s equivalent to insects, that are in various stages of digestion.
Then, suddenly, a bright light, a loud roaring of engines, and a strong gust of wind come from above the thicket. The creature reacts by releasing Osa and taking cover. Scrambling to her feet, Osa grabs the antenna and dashes back the way she came until she’s back in the light of this planet’s sun and locates her taser she dropped. She orders the ship to lower its entry ramp and hover over her. She climbs on, dragging the antenna with her.
Once Osa has secured the hatch and made her way to the control pit, she finds a rocky clearing to land on and continues her repair work after she gets a quick shower and changes her bio-suite.
Several hours later, it’s dark outside. Osa is using the ship’s running lights as well as her helmet lights to work with. There are all sorts of strange noises in the distance. Curious creatures that are investigating the strange light but cautious not to get too close. As soon as she can, Osa gets in her craft. She takes a 6-hour nap, awakened several times by the sound of something walking on the surface of the shuttle.
When she wakes, she eats and feeds Kaabo, freshens up, and cleans up after her dog. Osa puts a special fitted bio-helmet on Kaabo and takes him for a short walk. Then Osa puts out a general distress signal. It will be a couple of days before her call is received, so she decides to explore and get readings.
Osa can use the short-range sensors to detect things that humans would label as plants, fungi, invertebrates, and insects. Some new types of predatory plants that are mobile and generate animal-level temperatures.
Osa decides to go out again. Taking a hand sensor, a taser, a flare gun, and a machete on the outside of her bio-suite. She also takes a canteen of water and a pair of ration packs.
On her survey, Osa discovers a shallow stream. Scans indicate it’s H₂O, has a mineral content similar to Earth water, and has no contaminants that are harmful to humans. Osa decides that this is a good place to take a short break and test the environment. She sets a 45-minute timer on her wrist controls, then strips out of her bio-suite. The air smells heavy with the aroma of plant decay and humidity. Osa opens a pack of rations and eats a little. Then she steps into the cooler water, giving herself a proper bath.
While rinsing her hair, Osa hears a noise from behind her. Spinning around, she sees a four-eyed, six-legged creature sniffing at the crotch area of her biosuit. Then she remembered that she’s still probably leaking Kaabo’s sperm, and this creature is smelling it mixed with her pheromones.
Her guess is quickly proven correct when she sees what she can only guess is the creature’s penis extended from between its rear legs, and it raises its head to look at her. The penis on this creature has got to be nearly the size of an Earth horse. Osa says to herself, more than to the creature, “I hope all you want to do is fuck me with that massive cock and not eat me for food.”
Osa slowly crawls out of the stream and presents her naked body to the creature in a way that she believes is both sexual and submissive. The creature moves around behind her before approaching cautiously. It sniffs the air, then steps closer. It sniffs at Osa from a short distance before moving close enough to lick her cunny. A couple of tentative licks, and then it seriously begins licking Osa’s cunny with what feels like a 20 cm tongue. Lapping her leaking juices and probing inside her canal. Then, without warning, the creature mounts her.
The creature’s 40 cm cock plows 20 cm into her cunny on the first push. The next thrust fills Osa with 25 cm of alien beast cock, causing her to climax. Each thrust after that has Osa taking a millimeter after millimeter until Osa has 30 cm of alien beast cock deep inside. Becoming orgasmic is becoming more frequent. As it rams in and out of Osa’s cunny, the tip of its cock swells like a dog’s knot until it’s the size of two men’s fists on the end of a woman’s forearm. Her climaxes are peaking before the previous one ends. The creature keeps pounding away at Osa for several more minutes, then it thrusts in one last time and holds its place. Osa feels something rubbing on her cervix, followed by a sharp poke as something pushes into her womb. Osa has one last climax, the most intense she’s had with this creature. Then the heart starts to beat as the creature floods her womb with nearly 1000 milliliters of alien beast sperm. Osa’s uterus is stretched, and her stomach is swollen like she’s 10 months pregnant. She thinks it probably doesn’t even have proper DNA, much less matching chromosomes.
Eventually, the creature’s cock deflates and slides out of Osa, causing her to drop to one side. It sniffs at Osa’s cunny, then lies down nearby. Osa is on the verge of passing out when she hears her alarm activate. With all her energy, she crawls back to her bio-suite and gets dressed. Able to breathe once again, she’s lying on her back, her stomach rising above her, as hard as a rock.
Sometime later, Osa wakes up, and the creature is gone. The swelling of her stomach has reduced a bit, and the hardness is gone. She stands with a bit of effort and makes the hike back to her ship.
On her shuttle, she powers up the robo-doc, initiates the gynecology program, gets naked, lays on the exam bed, and has her uterus drained of the alien semen. The robo-doc informs Osa that she is free of foreign bodies, clean of any possible infections, and not pregnant by the alien. Osa shuts the auto-doc down and goes to find Kaabo. He is lying on the bed; without even getting dressed, Osa takes Kaabo out for a 20-minute walk around the ship.
The next morning Osa wakes up and realizes she slept through the entire night. Karabo is next to the door, looking at her. Without getting dressed, Osa opens the hatch, and Kaabo runs past her; she walks down the ramp to the bottom and watches for dangers as her dog goes about his business. Off in the distance, Osa sees a cloud in the distance. Then she realizes that is not a cloud but a swarm of small flying creatures headed in their direction, fast. “Kaabo,” Osa shouts, “Come in, boy! Kaabo, come in!” Kaabo perks up sensing the urgency in Osa’s voice, but he’s in the middle of relieving himself. As soon as he finished having his movement, he also noticed the cloud of swarming creatures. Kaabo runs towards Osa as fast as he can, but the cloud is closing in on their location. Osa continues to call to Kaabo, and he runs as fast as he can. As soon as he hits the ramp, Osa steps into the ship and hits the door close button. Kaabo leaps through the closing upper and lower catches, landing on the bed and tumbling into the wall unharmed.
Before the door is shut, Osa is running to the control station, where she attempts to retract protrusions (antennae, sensors, and landing gear), shut protective window shutters, and raise energy shields. The energy shields fail to come online, the ship tilts to an off angle when the landing gear is fully retracted, and the distress signal stops broadcasting when the antenna is stowed. She thinks to herself that a rescue ship should be there sometime in the next 8 to 18 hours.
Then she heard the first clank on the hull of the ship, then another, and another. then dozens, then an uncountable number. The swarm has arrived. Osa and Kaabo cuddle on the bed and listen to the sounds of the swarm climbing on the hull. The next thing Osa knows, Kaabo is nudging her to roll over onto her hands and knees. She looks at him and notices his pink cock is halfway out of his sheath. “You want some sex?” she asks him. His tail wags rapidly. “Fine, I guess there’s nothing else to pass the time. Besides, you already got me pregnant.” Osa gets on her hands and knees, wiggles her butt, and says, “Kaabo, fuck.” Kaabo mounts Osa and, with practiced skill, guides his 20cm of hard dog cock into her waiting cunny hole. Kaabo fucks Osa for 11 minutes before his swollen knot finally gets lodged inside Osa’s cunny, and he starts flooding her womb with his hot dog sperm, causing her to climax with him.
Osa wakes up to a pounding on the side of the shuttle. It’s not the swarm; it must have passed after she fell asleep. She doesn’t remember when she fell asleep. Then she hears the banging again. Three bangs and a pause, two bangs and a pause, three bangs, then it stops. The rescue party! She hops out of bed and runs to the door, pressing the ramp and door buttons at the same time; she anxiously waits to greet her rescuers. Kaabo moves over and stands next to her.
Outside she sees three human men in heavy-duty mining EVA suits. They all seem surprised to see her naked body, then one guy notices the runny liquid oozing out of her cunny and the dog standing next to her. One of the other guys says to her, “Pardon, ma’am. But might you want to get dressed?”
Realizing that she’s naked, Osa runs out of sight of the three men and puts on a biosuit. When she returns, she invites them in to inspect her shuttle. The three men take about 20 minutes to evaluate her ship. Henry tells her, “You’ve done a decent job with what little you have, but it’s far from space worthy. We estimate that you’ll last between 2 and 3 hours,” Haoyu injects, “or the first time you attempt to use a jump gate.” Henry continues, “before your ship ruptures and decompresses.”
Jack looks at the others. “Mandal could tractor her shuttle to our cargo bay and conduct more extensive repairs on it there. I know we don’t have the extra bunk space, but she can sleep in her shuttle. What do you think?” The other two men ponder the idea for a moment but eventually agree. Then they all look at Osa.
Osa looks at them and asks, “How long do you think it will take?”
They all look at each other, then back at her, and in unison they say, “70 hours.”
Osa smiles at them and says, “Sounds good.”
Osa packs her belongings, gets Kaabo, and follows the three men to their landing pod, which is about 1/3 the size of her shuttle.
Three hours later, Osa’s shuttle is in the cargo bay of the large asteroid mining ship. The whole thing is mostly automated with a small complement of cleaning, maintenance, and repair robots, plus the three miners (Sergeant First Class Henry Andersson of Sweden [Mining Mission Commander], Sergeant Haoyu Wu of China [Mining Mission Specialist], and Specialist Jack O’Malley of Ireland [Robotic Engineer]) and one pilot (2Lt Mandal Zuma of South Africa [Ship Commander]).
Jack and Osa are working on Osa’s Shuttle, making repairs to some external equipment that the mining ship had several extra spare parts worth. When Jack asks Osa, “What are you doing out here? Some secret Earth-Gov mission or what not?”
Osa tells him, “I’m a private explorer of new experiences.”
Jack asks, “What does that mean?”
“I cruise the galaxy looking for new places to explore and new experiences to partake in.”
“What kind of ‘experiences’?” Jack asks.
“New cultures, new species, new civilizations, new food, new sights, and new sensations of any kind,” she tells him.
“Well, what have you ‘experienced’?”
Last month, my brother and I went to a fun planet. We tried alien foods, met alien scientists, and took classes on sex between species. We also had sex with a few different alien species.
“Wait, you said your brother went with you? Did you and he...?”
“Fuck? It was a long journey. It took nearly 3 weeks and 7 jumps to get there. So, to answer your question ... Yeah, my brother fucked me. Fucked me a dozen times. He fucked me hard with his massive black cock. Flooded my pussy with massive torrents of his sperm every time. Tried getting me pregnant again.”
“I see your brother’s not with you, now?”
“He went back to Earth to be with his wife and our son.”
“Again?”
“He and I, and his wife, had threesomes for him to get me pregnant so they can have a child.”
“Ah, so you have been getting sex from your dog in your brother’s absence.”
“I have. It’s no different than having sex with an alien, except I trust my dog more than I would most aliens.”
