Chapter Text
Yushi loves eating. Not because he eats a lot, but because he genuinely enjoys food. Sion always says he eats well. Whenever Yushi gets full, he has a habit of rubbing his own belly. Once they grew comfortable with each other, that little gesture became his quiet way of telling Sion he was full.
Somewhere along the way, Sion's hand joined his.
Sometimes he rubs slow circles over Yushi's belly with the palm of his hand. Sometimes it's only the back of his fingers brushing lightly across it. Other times, his hand simply rests there as if that's where it naturally belongs.
It doesn't seem to matter whether Yushi is full, hungry, standing beside him while cooking, waiting in line at the grocery store, lying beside him before bed, or simply sitting next to him. Sion's hand always finds its way there.
Even in their most intimate moments, Sion still finds himself reaching for Yushi's belly, making Yushi flush every single time.
“Feel it?” Sion murmurs, his hand resting on the slight bulge of Yushi’s belly every time he thrust back in. Yushi can only let out a louder moan in response.
During Yushi's pregnancy with the twins, the habit only grew stronger. Sion rubbed his belly every chance he got. He never walked past without kissing it. Every evening, he carefully applied lotion and oil over the stretching skin. When Yushi's belly became too heavy, Sion would slip both hands underneath it to help support the weight.
At first, Yushi would grow shy whenever Sion did it. He never stopped him, though.
He liked it.
Years later, neither of them notices it anymore. It has become as natural as holding hands.

One afternoon, they're having lunch with a few friends and their partners. Sion sits beside Yushi as always, one arm draped over the back of his chair while his other hand rests naturally on Yushi's belly, idly rubbing slow circles over it as they listen to everyone talk.
Halfway through the meal, Sion stands. "I'm going to get our drinks." His hand naturally slips away from Yushi's belly as he walks toward the counter.
One of the partners leans over slightly.
"Can I ask something?"
Yushi looks up.
"Are you... perhaps pregnant?"
Yushi blinks. "...No."
The man scratches the back of his neck with an embarrassed laugh. "Oh. Sorry. I just thought..." He gestures vaguely toward Yushi's belly. "Sion kept his hand there the whole time, so I thought maybe..."
"...Oh." Before Yushi can explain, one of their friends laughs.
"Don't worry. He isn't."
Another nods knowingly.
"Sion's just like that."
"One of his hands is always on Yushi somewhere." someone else adds. "We stopped questioning it years ago."
"They're probably the clingiest couple I know."
Yushi lowers his head, his ears warming. "...I don't think we're that clingy."
"You are," everyone says at once.
Just then, Sion returns with the drinks.
"What did I miss?"
"Nothing," Yushi answers a little too quickly.
The conversation moves on.
A few seconds later, Sion's hand is back on Yushi's belly.
No one comments on it this time.
♡
Somehow, the twins pick up the habit too.
They're spending a quiet afternoon in the living room when two little hands suddenly find their way to Yushi's belly. Ryo stands on one side, Saku on the other, both gently rubbing small circles over it with complete seriousness.
Yushi looks down at them, amused.
"What are you two doing?"
The twins look up at him and blink.
"Daddy always does this," Ryo says simply. Saku nods in agreement.
"And why do you think Daddy does that?"
The twins shrug. They don't really know. Daddy does it, so they do it too. Yushi lets out a soft laugh. Trust Sion to influence the twins with even the smallest gestures of affection.
"What's up, babies?" Sion walks into the living room carrying two plates of snacks, setting them down on the coffee table.
"They said you always do this," Yushi says, glancing down at the twins, whose hands are still resting on his belly.
Sion lets out a small laugh. "Right." He walks over, leans down, and presses a quick kiss to Yushi's belly before burying his face against it. The twins immediately stop rubbing.
"Daddy," they complain in unison. Sion laughs again before straightening up.
"You know," he says, "Dada likes rubbing this part of my body too." Yushi rolls his eyes, though the corners of his lips still lift into a small smile. Sion places a hand over his stomach, right above his abs.
Curious, the twins switch targets. Tiny hands begin rubbing Sion's stomach through his shirt. Ryo's brows knit together.
"...It's different."
"Hmm?"
"Dada’s belly is soft," Ryo says, still rubbing Sion's stomach. "Daddy’s is hard... and has little bumps."
Saku nods seriously as if confirming Ryo's findings.
Sion can't help but laugh.
♡
Sometimes, though, Sion gets distracted. On those rare occasions, Yushi finds himself rubbing his own belly while quietly waiting for Sion to notice.
Every now and then, he glances at Sion.
Then at his own hand.
Then back at Sion again.
It never takes long. Sion kisses his cheek before gently replacing Yushi's hand with his own. Yushi withdraws his hand, completely satisfied.
♡
And without realizing it, Yushi has developed his own way of telling Sion how he's feeling. If he lets Sion's hand stay, everything is fine. If he quietly shifts away before Sion's hand can reach him, Sion knows something is wrong. Sion knows Yushi is upset.
♡
It's just one of Sion's many habits.
Yushi can't really say Sion loves his belly in particular.
Sion simply loves Yushi. Every part of him just happens to receive its fair share.
His belly is only lucky enough to be within reach most of the time.
