Nagito whistled to himself as he walked down the beach. Unfortunately, he wasn't very good at whistling so while to him, it sounded fine, to anyone else, it would've sounded obnoxious.

As he walked, he noticed Mahiru taking pictures of her surroundings, which was understandable. The ocean was absolutely gorgeous at any time of the day, but particularly around right now, at the eve of sunset. Nagito smiled as he walked up to her, and prepared to say hello. However, as he raised his hand and opened his mouth, his foot fell into a small sinkhole, and he fell forward. His hand naturally attempted to grab purchase onto something, and he did, however he simply took that thing down with him.

After striking the ground, he looked up, hoping he hadn't hit the girl by accident since he'd been pretty close to her, and was shocked to see what was clasped in his hand: a skirt and panties. Slowly, the boy looked up, and the sight above him was heavenly.

Mahiru's ass and pussy, on full display for him to see, thanks to the fact that she'd been standing with her legs slightly spread, allowing him to see her lips in full view. On top of that, her peach-shaped ass was gorgeous as the dimming light shone off her smooth cheeks. Mahiru stood frozen in shock, seemingly trying to comprehend what had just happened. Nagito's cheeks flushed as a painful boner sprouted in his pants, unable to look away from the girl's beautiful bits. It was true he'd always thought she was attractive, but now seeing her like this, it was…magical.

"KYAAAAAAAAAAAAAAAAA!" She finally screamed. Her asscheeks bounced as she jumped, and she quickly turned to try and fling herself away from Nagito. Instead, that only caused her to get twisted up in her underwear, and she fell back, the articles of clothing sliding off her body until she was left bottomless. She fell onto her ass, legs spread, wincing. Nagito now had an even better view of her pussy, and he could see it was completely unobstructed by hair. It was absolutely gorgeous, and the straining in his pants grew stronger. It took the girl a moment, but she was eventually able to recover, and realize what position she was in. Her hands shot between her legs as her face was as red as her hair. "NAGITO! WHAT THE FUCK?!"

"S-sorry, Mahiru, it was an accident, let me-" he started, before as he tried to get up to help her up, he slipped and fell back on top of her. This time, his head landed between her legs, her hands having slid up to reflexively catch him. This meant his nose and mouth were now directly touching her most sensitive bits. Mahiru trembled in shock, and she was about to scream again when Nagito spoke. "Again, sorry." He said, his voice sounding calm even if he was freaking out on the inside. His muffled voice vibrated her pussy, and she gasped in pure hot arousal as she grabbed his head by the hair. "M-Mahiru?"

"A-AH! G-get off of me!" Mahiru cried as his question shocked her out of her stupor. He tried to push himself up, but he slid back down on the sand, and now only did his face once again go between her legs, but his hand, in an attempt to grab onto something again, slid over her stomach and pushed up her shirt and bra. Her breast popped out free as he grabbed onto it, and another loud gasp escaped her. Her thighs clenched together as she moaned, which only further pushed her face between her legs. "F-fuck!" She screamed, and another moan got out when Nagito's hand squeezed, his warm fingers pressing against the soft skin of her breast.

Nagito then felt something wet on his face. It was clear the girl was becoming aroused, and the boy wasn't sure how to feel about it. Not knowing what else to do, he shot out his tongue to try and lick the stuff away, only for it to touch Mahiru, and she gasped again, grabbing his hair even more tightly.

Fuck, it felt so good. Why did it feel so good?! Mahiru asked herself these questions as she practically had to force herself to push him away, gasping her air as she felt dizzy. As Nagito pulled away, he found himself looking at a new, beautiful sight. Her blushing, sweating face, her completely exposed and wet pussy, her single exposed breast. It all was so…

"Hot." He said aloud.

"H-huh?!" Mahiru cried. It was then that she noticed the tent in his pants. Not only that, but how…big it was. Enough that she shuddered, and bit her lip as she sat herself up. "N-Nagito…"

"I'm sorry. Truly. You know how it is, my stupid luck. The universe deemed that this was what was considered lucky for me, even though I'm sure you're about to beat my face in and tell everyone how sick I am, which is deserved." He said as he braced himself.

"N-no, what's…" She took a deep breath. Normally, yes, she would've beat him until he passed out for what he just did, but…apparently she was much more pent up than she realized, and having Hiyoko almost constantly doting on her had given her barely any free time to take care of her…urges. She looked the boy up and down. Nagito was, surprisingly, somewhat attractive, actually. Despite his…insane personality, he at least looked nice.

She couldn't believe she was actually considering this, but as she stared at that tent, she sighed. She grabbed the hem of her shirt and pulled it off, along with her bra, leaving her completely naked, besides her socks and shoes.

"Mahiru?" Nagito questioned.

"I won't tell the others…if you'll…um…" Her face burned as she tried to say it. "I've been…feeling…pent up lately, and…what you did felt…good, so…"

"You want me to-"

"Do more of it, yes." She said. "And…take that out, p-please." She said it super formally as he looked down to where she pointed.

"Ah…" he said, and looked back up at her. "You sure you want that…from me?"

"No, not really." She answered honestly. "But…I don't think my rational brain is exactly at the helm right now, so…if you want this, you better say yes before I change my mind." She said, annoyed at how much her desire to see that cock was growing.

"Then…yes." He said, and without another thought, he unbuttoned, unzipped, and lowered his pants. His rock hard cock bounced free, and the girl gasped. Somehow, it was even bigger than she thought seeing it all hard and everything, and to be honest, even before she saw it in his pants, she thought it would be…small.

Not that she was complaining.

"How do you want me to-?"

"Don't care. Just so it, please." She practically begged. So Nagito did. He pleasured her as best he possibly could. He did everything, he worshipped her body like he knew he should, which definitely made Mahiru feel better once she was buttered up. He played with her breasts, her ass, and when he actually pushed himself into her, he did everything he could to prioritize her over him, which she appreciated. He even made sure not to cum inside her, and jerked off onto the sand to finish once she had cum herself for the fourth time in their little session.

After that, she thanked him, got dressed, and they both promised to never speak of what had just happened ever again.
