Zenith and Sam have known each other for awhile now, five years to be exact, they'd met each other when Sam was only on his 5th mission in space and Zenith had decided to stowe away on the odd space craft he didn't recognize in an attempt to get away from his planet and he's species feral mating habits, when Sam first found the large alien he'd practically screamed like a little girl as he grabbed a fire extinguisher and chucked that shit at him, he ended up being extremely embarrassed when he realized the alien was absolutely no threat to him.. Though at the time Zenith was just glad that the small human had allowed him to stay when he explained his situation, humans and their empathy.. It was a nice change to Zenith in all honesty.

Though now, a whole 5 years later and the two men were in a committed relationship, it was almost hard to believe that Zenith fell for the man who threw a metal fire extinguisher at his head but it also.. Wasn't all that surprising at the same time, he won't ever admit it but it was actually incredibly hot that he could stand up to him, though threw out their relationship there has always been a few things that they were glaringly aware of- the first thing being Zenith himself, ever sense Sam brought him on board he made it very clear that no one could know at his work that he had an alien on board, other aliens? Completely fine, but none of Sam bosses or other Astronaut's could be aware that he was here or on board, for a multitude of reasons but mostly for Zenith's safety and Sam's job, that only became more important when they started dating, so any calls or other Astronaut's that they came across Zenith would hide, and the second thing.. Well, was that they would likely never go all the way.

Not because Zenith was to much for a human to take, no Zenith is big but manageable, the real problem is that neither of them are very keen on taking it up the ass- every time either of them talked about the prospect of one of them bending over they found themselves uncomfortable with the idea, it wasn't like it was a horrible thing though, it allowed them to explore other ways of getting each other off without any penetration- a lot of things worked for them, some didn't, it was a learning experience but both were determined to do whatever they could to keep each other comfortable during their time together, and despite Sam's attempts at keeping a third issue hidden from Zenith it's finally all come to a head a few weeks ago..

Sense Sam had to keep Zenith's existence a secret from everyone back on earth NASA had been pretty insistent that they send another Astronaut up there to keep Sam company and sane while he's up in space, though of course a turquoise space lizard is living with him so he's declined over and over again, not thinking much about it sense he always looked and acted just fine so why would they send someone up? Well apparently he was incredibly wrong because they decided he couldn't keep living in space alone, especially sense they eventually wanted him to go further, so they did it anyway and told Sam that he'd simply have to deal, pretty quickly Sam had to spill what was happening to Zenith- thankfully he wasn't to angry.. Still decently angry but at the end of the day he knew it wasn't Sam's fault.

What neither of them anticipated however was that the Astronaut was going to be such an appealing man- I mean the second Sam saw him he was practically stumbling over his words as he showed him to the bedroom on the space ship, he didn't even have to explain anything to Zenith either because Zenith found him incredibly sexy, they were both just on their bed giggling and kicking their feet at the thought of him, not actually but they thought about it.. Which is why when Sam left to do some night time gating of samples on a small planet they landed on earlier that day Zenith couldn't help but decide to dust off his old mating style in an attempt to woo the man, so he went as quietly as he could to the Astronaut's bedroom and moved to get on the bed and over his sleeping form, before he could fully do something to the smaller man however Sam had come back and nearly had a damn heart attack when he saw Zenith over his very asleep body..

"Zenith- what the fuck are you- get off of him-!"Sam whisper yelled incomplete sentences as he got closer to try and grab Zenith by the shoulder, he was utterly panicked because fuck what was Zenith thinking?! Climbing on top of him while he was asleep- though Zenith only used one of his hands to swat Sam away

"No shush I know what I'm doing"Zenith shushed him as he tried to get Sam to let him be, he knew what he was doing! He could.. Woo the much smaller human, humans like men who take charge right? That's what all the movies say.. Movies haven't led him astray yet, yet being the key word..

"No you don't! Get off of him you horny reptile!"Sam whisper yelled as he demanded Zenith get the fuck off of the other Astronaut, he loves Zenith but he can promise that he absolutely dose not know what he's doing when it comes to impressing humans, he vaguely understands what he's species customs are so he definitely understands this isn't correct..

Sam and Zenith continued their whisper argument as Zenith stubbornly stayed over his sleeping body, determined to try and woo him despite going about it in the oddest, possibly creepiest way ever, at some point Sam grabbed a hold of Zenith's tail to try and pull him off, one foot was planted firmly on the ground while the other was on the bed frame to try and get leverage on the bigger alien but.. Zenith is just to big, and Zenith sure as hell knew it so he only huffed in amusement, he loved he's silly little human.. Though as he looked down at him again he froze up upon seeing that he was also looking at him, Sam upon feeling and seeing him tense up moved to let go of his tail and move closer to the side of the bed thinking he had accidentally hurt him, he almost wish he had when he saw him looking between the two of them..

"...What's cookin good lookin?"Zenith stated after 5 minutes of tense silence, trying to make this look better then it actually was.. Sam groaned loudly from beside him, having to cover his face from utter disappointment at his boyfriends words, Zenith has to stop watching those horrible romcoms..
