Summary
Saiki wakes up with a problem he's never dealt with before. Morning wood. His decision on what to do about it leads to several mortifying interactions he would much rather pretend never happened, and the fallout uncovers burdens he's tried to keep hidden from everyone - including himself.
Like I mentioned in the tags I'm not completely sure how graphic something needs to be to earn the "graphic depictions of violence" warning (I'm very new to AO3) but towards the end of the story I did write a couple somewhat violent scenes. While I don't think I wrote anything that you couldn't find in a shonen anime, I did show a bit more mature content than the Saiki K. anime ever does and at times I used much more candid language to discuss things. See the notes before each chapter for more specific warnings wherever they apply.

Summary
He shook his head. He didn’t regret it, not really. It had felt good, and Aiura was exactly the best person to experience this with. She wasn’t ashamed, she was happy to take the lead, she understood Saiki’s reservations, and she had been so, so patient with him, even while she attempted to convince him to do this in the first place.

When the final bell rang, he could hear her thoughts settling on which coupon she was going to cash in. She strode to his desk before he stood up to leave and dropped a crumpled sheet of paper on his desk as she walked by and out the door.
See you tomorrow, babe, she thought without a single word escaping her lips.
Saiki picked up the little shred of paper and unfurled it, even though he already knew what it said. One beach day.
