Notes

Written for fic_promptly on dreamwidth. The prompt was going to the beach.

Title is from 'Beaches' by beabadoobee.

“Hey Momo, let’s go to the beach.”

Momo turned his head to look at Yata, taking a slow drag from his cigarette where they stood next to each other on the balcony.

“The beach?”

Yata nodded, staring into the calendar on his phone, clearly planning things out. “We’ve still never been together, right? Wanna go this weekend?”

Momo felt his heart rate pick up, and he looked to the side, avoiding Yata’s eye. “I’unno, I promised to cover someone’s shift on Saturday.”

Suspicious eyes narrowed, Yata leaned in close. “Why’re you lying?” There was a worried glint in Yata’s eyes until they widened as if having come to a realisation.

“Momo, do you not know how to swim?”

Momo leaned his cheek on his arms where they were resting against the railing, and he turned his face away from Yata. His red ears were still visible in the light from the light posts lining the street. “...’s not like I had anyone to teach me,” he muttered.

“Don’t worry, I’ll teach you.”

When he peeked over at Yata again, the warmth of his smile made him feel mushy on the inside.

The sun was hot against Momo’s skin as he stared at the sprawling shoreline. Yata set down his bag on the ground, as Momo let the sand sink in between his toes.

His eyes caught on two children running by, shrieking with laughter. He quickly turned them toward Yata. “I’m not wearing those arm-thingies.”

Yata snorted in amusement, clearly finding the image funny. “I don’t know if they come in adult sizes. You’d be adorable in them though. Like a toddler.”

Sticking out his tongue in response hardly made Momo seem more mature.

“Okay, we’re gonna start with floating. Give me your hands.”

 

The water lapped at his waist, the surface colder than he would have expected. It made him shiver for a moment before giving Yata his hands. They grew warm as Yata’s hands swallowed his.

“Bend down so your face is right above the water, inhale and hold your breath, then lift your feet. I’ll hold you up.”

Momo put on a sly grin, even as he felt himself grow stiff with anxiety. “You know, if you wanted to get me dick-height, there are easier ways to do that.”

Yata’s cheeks flushed. “Hey, focus! It’s important to know how to swim!”

Momo gave a dismissive ‘yeah-yeah’, but he lowered himself into the water regardless. Every new centimetre that hit his skin made his nerves react to the cold refusing to let go of the surface.

After a moment of hesitation, he lifted his feet up, stretching his legs as Yata kept him from going under. Yata smiled brightly at him. “You’re doing great! Try to relax your body and it’ll be easier.”

Personally, Momo felt like his legs were barely above the sand. He opened his mouth to say as much, but as soon as he did, his feet met the ground again.

“I sank,” he groaned with a grimace, standing back up again..

Yata grinned down at him. “Well yeah, you breathed out all the air. If you want to stay buoyant you gotta keep it in.”

“If I wanna what?”

“Float. Wanna try doing it on your back instead?”

When he nodded Yata moved to stand behind him, moving his hands toward his back. When the touch strayed close to his armpits Momo let out a loud cackle. “Hey, that tickles!”

The smile on Yata’s face was wide. “I’ll hold on more tightly then.”

 

Letting himself be lowered into the water, Momo stared up into Yata’s face. His face was cast in shadow from the sun beating down on them, but he could still catch the happiness in his eyes. It made Momo avert his eyes, flustered.

He stared up into the sky, tiny clouds sparsely dotting the bright blue of it. Yata’s voice was muffled as he told him he was doing really well, and his eyes moved back to Yata for a moment. Every sound beneath the surface was amplified by the water, making it hard to hear what was happening above it.

Just as he was starting to relax more the wind picked up just enough to wash a wave right across his face.

In under a second he could hear his heart pounding in his ears, and it was a struggle not to gasp for air. He shot to his feet, coughing, stumbling forward. Yata’s hand grabbing his arm was the only thing that kept him from falling face-first into the water.

He didn’t see the sea anymore. It was like it disappeared right in front of him, leaving him unable to take it in at all.

He could only feel the water, the phantom hands holding him down underneath it even as he was choking with a cock down his throat, bubbles escaping the corners of his lips. Invisible hands squeezed around his neck, depriving him of oxygen.

“Momo! Momo, it’s okay, I’ve got you!”

 

He hadn’t noticed when Yata had gotten him out of the water, but it felt like out of nowhere when he found himself in Yata’s arms, only his toes grazing the surface of the water as Yata made quick strides toward the beach.

He was set down on top of his towel, Yata sitting down right on the sand in front of him. “You okay?” he asked, running his hand along Momo’s face to get his hair out of his eyes.

Momo’s smile was trained, and he rubbed the back of his neck with a hand. “Yeah. I dunno what happened. I’m fine.”

“I uh… I know you’ve never really gone swimming before and all, but have you almost drowned before? Your reaction was pretty strong.”

“Kinda. It was at an onsen though. This dude made me dress like a mermaid so he could fuck me with a fin on. Takes a lotta work sucking someone off underwater, you know. Especially when the heat gets to ya.” He rested his hands in the sand, feeling the grains stick to his still-wet hands. ”Made me stay down there til I passed out.”

The look in Yata’s eyes was gentle, and his thumb rubbed against the swell of his cheek. Trying to bypass the vulnerability of the moment, Momo laughed. “I was a pretty cute mermaid though.”

Yata’s smile stayed gentle. “I bet you were.”

Momo stared into Yata’s eyes for a long moment, before he shook the sand off his hands.

 

“Hey, let’s give it another go.”

Yata’s brows furrowed. “You sure?”

“Yeah, I trust you.”

The happy flush on Yata’s face made Momo laugh, and he grabbed Yata by the hand.

“Come on, I still wanna have time to have sex on the beach after!”

“You mean the drink, right?”

The grin on Momo’s lips was face-splitting. “You’ll find out later.”

 

Laughing even as he shook his head in exasperation, Yata let himself be dragged back to the sparkling blue sea.
