My Own Science (Dr Stone Senku x reader)

Back to the plot!

[Actually nah, I don't wanna write smut. It is within my abilities, it just feels weird to write Senku having sex so yeah]

You woke up to the sunlight peeking through the porthole, you rubbed your eyes before slowly opening them. Not seeing Senku lying beside you, you looked around and saw him standing by the door (you both slept in the training room), leaning on the wall with his arms folded. He still had no shirt on. You kinda insisted that he took it off last night because you felt weird being the only one with no clothes on.
"Morning."
"Hey." you said with a tired voice. "What are you doing?"
"Just wait."
"Okay...?"

You rolled back to look at the ceiling, bringing the blanket under your arms to cover your exposed chest. You didn't mind waiting, you still needed some time to process what happened.
Last night was...something. Boy was it something!

You flinched when the door started to open, but just as you gasped and sat up, Senku put his hand on the door, preventing it from opening further and stood in front of the opening, hiding you from whoever was at the door.
"Yeah?" he said.
"Senku?" you heard Tsukasa said and you cursed yourself for forgetting about him. "Does (Y/n) know you're still in the training room?"
"I don't know." Senku glanced at you. "(Y/n), do you know I'm still in the training room?"
"Oh my fuckin god!" you covered your face, red from embarrassment.
"Ah, I see." Tsukasa said. "I'll leave you to it then."
"Thank you." Senku smiled before closing the door.

You threw his pillow at his face.
"I cannot believe you!" you exclaimed. "What happened to you?!"
"You don't like it?"
"I mean...I didn't say that."
'It was a cool line.' you thought before speaking again.
"But that's too much change coming from you! You get jealous, you take the lead and you just gave a jealous-boyfriend-one-liner."
"Kukuku, don't worry." he smiled. "That was a one-time-only thing. When it'll happen again, it'll be because you wanted it."
You heart skipped a beat.

"After that, I'm good for the next, maybe three years."
"Cool." he smiled, putting his shirt back on. "Now can we please go? You have your training, and I have a whole ship to manage. Or is this a thing people do after sex? Lying in bed all morning like they have nothing better to do?"
You smiled.
'There he is~, that's the Senku I know and love!'
"Give me a second." you said before quickly getting dressed.

Before having breakfast, you went to Tsukasa, too embarrassed to look him in the eyes.
"Um, Tsukasa?" you said. "About this morning...Well first of all I am so sorry."
"It's alright." he smiled. "I understand how Senku would feel about his first session."
"His what now?" you looked directly at him.
"It's common for people to workout in private at first. I just hope he'll feel comfortable enough to not do it in secret one day. Maybe even join us!" he seemed to get enthusiastic at the idea.
'Oh Tsukasa, you and your pure heart!!!'
"Well actually," you gladly followed him on this. "he told me he'd try training once. So we did and he said he wasn't that into it."
"Oh, shame." he looked down, a bit disappointed. "But I understand, it's Senku after all."
"We'll get him next time."
He chuckled before you walked away to get breakfast.

As soon as you turned, you saw Gen smiling at you. He must've heard your conversation.
'Oh boy.' you thought.
You knew Gen and you knew that smile! It was the smile that said 'I know what you did and now I want the details!' You sighed and gestured him to walk with you. It was tea time.
After getting your food, you both sat down at a table which was at a certain distance from the other. Leaning towards each-other and speaking quietly. You told him what happened (leaving out the act itself of course!) and he nodded along.

"So did he also...?" he asked.
"Nah, nah he's asexual."
"I knew it." he smiled to himself.
"But weirdly enough, I feel like he still got a kick out of it, but in his own way...? I don't know how to explain it."
"Well of course it'd get a reaction out of  anyone. That's not just a step in your relationship, it's a whole staircase."
"It sure felt like it yeah."
"And how was it?"
"That-no!" you leaned back and held up your index, blushing. "Those information are classified."
