"It's all good, Ex. You can come out now."

The keeper of dimensions wasn't sure if he was ready for this. Maybe should've thought this through. "Zed… I need a second.", he called out.

"Take as much time as you need.", the robot comforted. "I want you to be ok as much as I do the rest of the crew.", Zed could not show it, but he would be smiling if he had a mouth.

As Ex stepped out into Zed's line of vision, he thought about how the hell he ended up in this situation: He had talked with the robot a few days ago, in another desperate attempt to reclaim Zed's role as his daughter's father, in her eyes. Zed was his creation: his solution to take care of his son and daughter as he left the life he had spent years cultivating to live at the edge of spacetime and fulfill his duty. Upon his return from his isolation when the Tetra Crew and their new friends rediscovered his existence, he had learned Zed had worked… a little too well.

When he went to talk to Ess one on one, she acted like she didn't recognize him, and was overjoyed when Zed came into the room, calling out "Papa!!!" and rushing over for a hug. It broke Ex's heart into a thousand pieces, even if he didn't show it to anyone on the ship. When the Tetra Crew would come to visit his home, he would try to talk to Ess, only for there to be no fruits of his labor, and to still be at square one. Attempt after attempt, it seemed like a lost cause to rekindle his fatherhood with Ess.

And that's where this dumb idea came from.

He wasn't sure exactly what compelled him in the first place, but that's when he came to Zed with a proposition during a late night visit, before Zed had to go and recharge. He explained it the best he possibly could without sounding insane. If he and Zed got into any form of a relationship, by technicality Ess would have to admit she has two fathers. He was surprised that Zed actually agreed to the idea of tying the knot in this fashion, but thanked him graciously and set up a time for this moment to occur. The fact there wasn't really a private area on the ship to copulate, but Ex was able to convince Tee to take a nap and give the cockpit to him (he had put the ship on autopilot, remembering exactly where the button was from when he manned the ship), and now it was just the two of them, ready to enjoy each other's company.

Ex had kept on his frilled shirt, bowtie and gloves, but ditched his suspenders, boxers and boots, pushing them to a corner in the room. His face was flushed red with embarrassment, his cock flaccid. "We need to make this quick.", he states firmly. "I have no idea when Tee will wake up from his nap, if he's even napping."

Zed nodded. "Of course I know. I just want to make sure you're going to be ok with this.", unusually, his speech trailed off as the sentence went on, something Ex never heard him do. He looked him from top to bottom, gasping at his nether region. "When did you—!?"

"Oh, this?", Zed looks down as well. Ex was sure he hadn't designed him with the intention of also having a penis of his own. For gods sake, he was meant to take care of children! "I'm… not exactly sure myself. But rest assured, when we finish, you can help take it off.", his reassuring tone made Ex's dick twitch in anticipation. "But first, I just need to ask some questions."

"Go right ahead…"

"First, I must ask… is this your first time doing this?"

Ex hesitated, even more embarrassed. The answer was yes; when he was way more youthful and brash, freshly 18, he and someone he was once friends with experimented with sodomy a few times, from that age to their mid twenties. (The last time they ever engaged in such an act was after a falling out, filled with such rage Ex found himself incapacitated for a few hours after his ex-friend quite literally fucked the wind out of him. But that was another story for another day.) After all that, he was never on the "receiving end" of penetration, he was the one doing it before his wife disappeared. After enough hesitation, he answered Zed. "A long, long time ago."

"Did you bring any lubricant, and did you clean yourself? I don't want this to hurt."

Ex sheepishly had to return back to the discarded clothes pile to fetch it out of his suspenders. It was too small for Zed to properly open, but Ex popped open the cap once he grabbed it as well. "I got it, and don't worry, I'm all clean."

"Lastly… are you sure you want to do this? I'm fine with calling it quits before we begin, Ex. I can see it in your face that you're embarrassed."

"… I'll be fine, Zed.", Ex sighed, accidentally emptying half of the bottle on one of Zed's prongs, dropping it on the floor soon after. "Shit- my bad- let's just get this over with quickly, ok?"

Ex quickly got on his knees for Zed, shuddering at the cold floor pressing against his nether region in this position. He also buried his face in the floor, just to muffle any potential moans or obscenities that would come out of his mouth. He shifted up a bit, making sure Zed could reach his asshole. Zed crouched down a bit, pushing the prong with the lube on it on his ass.

This quickly gets a gasp out of Ex, both at the pushing feeling and the coldness making him shudder. "Brace yourself.", Zed warned, before pushing in further, parting his asshole open for him to rest inside. Ex quivered under the feeling, his dick getting harder. "Holy shit, Zed…", he gasped, breath heavy. "Farther.", he commanded

Zed nodded and continued on further, pushing in as deep as his hand could go. Ex put one hand over his mouth to suppress the loud groan that came out of his mouth. "You enjoying yourself?", Zed asked. "You want me to move now?"

"Please.", Ex begged. He had forgotten how good being fingered like this was. "I…", he started with shaky breath. "I need it."

He moaned loudly feeling it go in and out, a lovely rhythmic pace to it all. Now Ex was no longer regretting the choice that lead to this, silently thanking himself for his desperation. He tries to grip onto the cold floor beneath him when he feels Zed's hand hook around his prostate, a powerful wave of ecstasy and arousal flooding through his body and his cock becoming completely rock hard. "Zed… my god, Zed.", Ex cried. "I think I'm gonna—"

Before he could finish the sentence, he cried out in pleasure, cumming over the floor. Zed removed his hand from Ex's anus, it now being properly open for what was going to happen next. Ex staggered back up once he was done, shaky legs and breath. "You look very happy, Ex.", Zed remarked, kneeling down to clean up the puddle. "I… I am.", he admitted wholeheartedly, a smile on his face.

He picked up the half-empty bottle of lube, quickly walking over to Zed once he had finished the clean up, pressing his body against the cold metal of his chest. "I'm ready.", it's a matter-of-fact statement this time around, as he empties the rest of the bottle on Zed's cock.

Zed responded by lifting Ex up with one of his hands (which made Ex yelp slightly, but he tried to brush past the shock), beginning to bring him down. Feeling the tip of Zed's cock brush against his open hole made him quiver with excitement. He was so, so ready.

The push in felt odd. Ex, in his lust filled haze, didn't stop to think about what it would feel like inside of him. Before he entered this state, he thought it would be cold as the rest of his body and generally unpleasant to deal with. He was pleasantly surprised to discover that it actually seemed to have a silicone casing around it, like a dildo. "Oh, yes.", Ex whispered to himself.

After that first push, Zed quickly found a nice, gentle pace for Ex, going in and out as the keeper kept babbling to himself in silence. Zed had never seen Ex get worked up like this, only ever being exposed to the strong, yet kind keeper. It was actually… kind of cute, he had to admit. Ex eventually let one of his hands slip and grab his own cock, stroking at a faster pace than the motions inside him, smiling like an idiot every time Zed manages to hit his prostate.

It didn't last as long as Ex would've liked, but he eventually groaned and came all over the floor once more. Zed seemed to follow, but it was more of his cock simulating the feeling of being filled up than it actually happening (Though to be fair, Ex preferred this. It's better than the potential of an ass full of oil, after all.), slowing down to help Ex ride out his second orgasm. Truly, this turned out to be all worth it…

"What the—!?"

Ex looked up only to see the sight of a horrified Tee, mouth agape as he walked into the cockpit. It was only then did Ex realize that one, he didn't find a way to make sure nobody walked in on his and Zed's rendezvous, and two, Tee caught them in the act. "Ex!? What are you doing in here?"

His face became extremely flushed as Zed let him go, Tee walking over. "… You enjoy that nap?", Ex tried to brush past discussing what he was just doing to the captain.

"…… You know what? I don't think I wanna know what you two were doing.", Tee shudders, looking down at the cum in the floor. "Don't do this again here. Please.", he began to leave, looking extremely disappointed.

Reasonable… Ex thought, grabbing Tee's shoulder before he could leave entirely. "Just… don't tell Ess me and Zed did this, ok?", his face was now as red as a tomato once more. Now that the post-nut clarity had hit, it actually was definitely best that Ess never knows what happened here.

"I guess your secret's safe with me…", was the last thing he said before walking out.

With Tee gone, Ex and Zed quickly cleaned up the mess, and Ex put the clothes he discarded back on. "I'll get the tools to get it off of you. Just wait here.", he said, before leaving the cockpit and getting ready to spend the rest of the night getting rid of that damn dick.

Once he got back home from it all, and Zed was back to normal, Ex promptly went to sleep, only waken up from the slumber to see a new status report from Tee. Oh boy. This wasn't gonna go well.

When he listened to it, he got what he expected:

Status report… Ex, what the fuck.

I don't know what else to say, really. Like… why do that? In the cockpit of the ship??? You are genuinely so lucky I was the one to see you and Zed, and not Ess or the twins. I didn't want to see that either. How did Zed get a dick? I don't want to know. I won't be able to see him the same way for… a long, long time.

I have to repeat myself… what the fuck. I'm gonna keep saying it until it stops affecting me. What the fuck.

Ex sighed, going to respond himself. "Tee, I'm sorry. It was a moment of weakness in a way. I thought we would be fine… I guess not. I promise you, I won't try it again in the Tetra."

Once he sent it, he went back to his duties.

Hey, at least he had more fun than he had in a long, long while.
