Summary
Ever since the scourge virus decimated their population, the Viltrum Empire has waited long to find a world suitable for breeding, for the goal of repopulating their species. Many of the Empire's most trusted officers have been sent across the universe to find a suitable world. Earth was identified. Many agents of the Empire were desperate to undertake this glorious burden. But Grand Regent Thragg believes in a different choice. The least obvious choice for the mission. The man deemed too unstable to even befriend one of his own kind. The man whose true name has been lost to time. Conquest. The Grand Regent believes that Conquest can take control of Earth in one swift stroke, and quickly create a significant number of offspring in order to ascertain the purity of the human species. But things never quite work out as one would expect...

Summary
Mark wished he could defend himself by saying he gave in to his desires for mere fear and not arousal and desire in response to power but he’d be a huge liar.
He blames it on presenting while getting beat up by his father to explain his taste for pain and humiliation.
Then it comes to him that he worded it as though he wanted to end their arrangement rather than offering the alternative he came up with. His mouth opens in a flash to defend his case but Conquest beats him to it.
“You want to be mine.” Conquest says confidently, mouth stretched in a grin.
Mark clicks his mouth shut right away.
Or… yeah, he could have been interpreted that way as well.
“That’s not what I meant.”
“Didn’t you?” Conquest nearly purrs.
“No! Are you even listening to me?”
or: Mark and Conquest's second encounter, this time Mark wants to try another alternative to prevent getting knocked up by the man his father wouldn't approve of. Anal sex.

Summary
After nearly dying at Conquest’s hands, Mark Grayson lies broken and unconscious on a desolate alien planet. With no food, no help, and no way out of deep Viltrumite territory, Nolan comes up with a very unorthodox solution to save his eldest son: his own cum.
What starts as pure survival quickly spirals into two months of raw, taboo depravity as Oliver discovers just how much his father is willing to give… and how much he’s willing to take. Now Mark is finally waking up, and the real complications are only beginning.
Incest has never been so lifesaving or so addictive.

Summary
Elena was taken from her home about two years ago, by her own estimations. Taken and gifted to a Viltrumite soldier who was known only as Conquest.
She didn't know her purpose. Not all of it, anyway. He was hardly there. Had no interest in her. It wasn't a bad life, exactly... she just wanted to go home. It wasn't the life she wanted.When her purpose is finally told to her, she does everything she can to try and not go as insane as he is. But there are worse things out there than a life with Conquest.
(I have not read the comics and I also have no real intention of seeing the show, but my partner showed me this old man and told me his lonely backstory. Next thing I knew, I blacked out and woke up to this on my desktop. Enjoy!)

Summary
The war spiraled out of control. Fists gave way to science, leading to viruses spreading beyond intent, containment, and any cures. Alone in his dead universe, Mark lived out his days in increasing ferality until a freak lightning storm teleported him back in time - to a Viltrum in the midst of its purge.
"Grand Regent," Kregg began, a rare note of uncertainty in his voice. "There is a... situation."
"Report," Thragg ordered.
"A rogue element has emerged on the planet. It's defying your will."
"How so?" the Grand Regent asked.
"It's protecting the wounded," Kregg said, "and has taken several children and a youth captive."
