You weren't really expecting to find romance on this 382 day long trip hauling cargo into fucking space, but the universe managed to surprise you. More specifically, it surprised you with a mechanic's intern around your age named Daisuke Juarez.
When you heard he was only there due to his parents making him get a job, you assumed he'd be a typical spoiled, rich kid. That was definitely another surprise. Turns out, he was actually a really kind and optimistic person. Sure, he was clueless sometimes (that was undermining it a ton), but he seemed like he genuinely wanted to do a good job.
Another thing about Daisuke? He was a massive gooner. The guy practically only thinks with his pants. You knew this before going out with him, and it didn't really bother you. After all, how much can one person touch themselves??
You were quite surprised by the answer.
At first, it was only during intimate moments. The rest of the crew would be asleep, you'd start making out in the lounge, and all would be fine, right? Until you suddenly felt something rising in his jeans, and he'd quickly excuse himself to 'use the bathroom'. He'd return after a while looking sweaty and satisfied and you'd go on to just have a regular conversation until you went to your separate quarters.
Then it started happening all the time. You glanced over at him while he was talking with Swansea? Instant boner. You put your hand on his knee underneath the table where everyone was having breakfast? Yeah, the table wasn't the only wood there. You made an innuendo in earshot of him? Immediately running off to his quarters. This earned you plenty of teasing remarks from Anya and confused looks from Curly.
Tonight was pretty much just like every other night. 140 days of his bullshit, but you were hoping that something would change. You were practically on top of him, lying on one of the couches as you pressed your lips against his. After about a second, you decided to move your hand up and grip a part of his hair. Big mistake. You could literally feel it.
He quickly pulled away, slowly moving away from you. He was clearly trying to act normal (and failing miserably). "I'm fine! Totally fine!" He said way too quickly. "I'm just gonna go, uh....stretch. In the hallway. Far away from you. For....health reasons."
The stammering and red face was one thing, but the clear outline of something in his jeans made it pretty obvious what he was trying to hide. And he wasn't doing the best job of it.
