Shouto shuts his eyes and waits for the judgment to wash over him. But it doesn’t come. A gentle hand traces over his cheek and a thumb brushes over his eyelids in a featherlight touch. As soon as the hand moves, Shouto opens his eyes to look up at Inasa.
“There’s nothing to be ashamed of, love.”
“I know,” Shouto says, and he almost believes it. “But I don’t want you to hate it. I want you to enjoy it.”
Inasa sighs quietly, and leans against him until they fall back onto the bed together with Inasa weighing heavily on Shouto’s chest. Inasa’s chin painfully pokes into Shouto’s sternum, but he doesn’t want to lose the comfort of that pressure on him by pushing away.
“Okay,” Inasa says quietly. “So you want to call me daddy, right? I can—”
“No,” Shouto swiftly cuts him off. “I want you to call me daddy.”
Inasa freezes. Shouto holds his breath while his boyfriend seems to rewire his brain. It takes a while but Shouto’s always patient for him. Shouto waits, lifting Inasa’s hand to kiss the palm. Inasa reflexively softens under the gesture, like it brings him back to the present.
“I still want you to fuck me though.”
Inasa twitches and stops moving again. Shouto looks away, not wanting to see confusion distort Inasa’s face. He had worried about coming to Inasa with this, but he was promised they could do whatever Shouto wanted.
“Your birthday, your choice,” Inasa had told him, though Shouto’s sure the expectation had been a favorite restaurant and a day out together, not a request for daddy kink in their sex life.
Now, Shouto waits, kissing Inasa’s thoughtful face to soothe him while he ponders. Eventually he feels hands on his hips, thumbs tracing patterns into the sliver of skin exposed between his waistband and the hem of his shirt. When Shouto kisses him on the mouth, Inasa responds immediately, almost painfully slow.
“Whatever you want,” Inasa whispers against his lips. “I’m happy to do whatever you want, daddy.”
There’s a pause before the last word, a hesitance, but Shouto rewards him with a kiss. Inasa pulls his weight off to pin Shouto between his legs with a knee on either side of him.
“I want to take care you,” Inasa continues on. “Let me take care of you, daddy. Please.”
Shouto groans and lets his legs slide open. When Inasa reaches out to grab lube, Shouto uses the momentum against him and pushes him onto his back and climbs on top of him. He tears off his own clothes while Inasa just stares as him.
“I thought you wanted to make me happy?” Shouto asks, his pout exaggerated as he gestures at the pants Inasa’s still wearing. “Do you need daddy to help you?”
He doesn’t wait for an answer, just starts tugging everything off as quickly as possible, before straddling Inasa’s hips. Inasa pulls his knees upright until his thighs touch Shouto’s back.
“You’ll let me take what I want?”
Inasa nods, and his dick twitches against Shouto’s hand. He squeezes, maybe a bit too hard, just to watch him squirm.
“Yes, daddy. Please take—” he gasps when Shouto runs his thumb over the slit of his cock. “Take everything you want. Daddy.”
Shouto sighs at the word, leans back against Inasa’s thighs, while he casually tugs at Inasa’s dick and listens to his every little noise whenever Shouto changes his grip.
“Please, baby,” Shouto says, eliciting a groan. “Want you inside me.”
Shouto only slides lube over Inasa's cock before tossing the bottle away. Inasa makes to sit up and protest, but Shouto covers his mouth with a hand, and presses his knees tighter to Inasa's waist.
"I have been getting myself ready for you all day," Shouto tells him a low voice. He can feel Inasa shiver against him and it makes him feel powerful. "I was alone all day and I need you. Right now."
Inasa moans, and he reaches toward his dick, grabbing at it clumsily. Shouto pushes his hand away and guides it where he wants it.
"You need your daddy as much as he needs you," Shouto murmurs.
He hovers over Inasa, their bodies barely touching. He finds he needs to wait until the time is right, until Inasa practically whimpers underneath him.
"Daddy." His voice breaks the word into two drawn out, desperate syllables. "Please, daddy, you're always right. I need you."
Shouto smiles at him in one moment and sinks down on him easily in the next. Inasa's so big, and Shouto wishes they could stay connected like this forever. Instead, he draws it out as long as he can. He rests a hand on Inasa's chest; not forcefully, but to ask him to stay put. And he does. He's so good at listening to everything Shouto tells him, even without words.
So Shouto moves at his own speed, as slow as he can make it, wants to make Inasa absolutely beg for him. When Inasa's switches from gently petting Shouto's sides to pulling at his hips, Shouto pushes his hands away. Inasa whines out a pathetic, needy sound.
"Shouto, I can't wait any longer—"
The sentence is cut off with a yelp when Shouto pinches a nipple.
"Shouto, I—" Shouto does it again to the other nipple and Inasa yells louder and Shouto feels the dick inside him pulse.
"I'm sorry. Daddy. Please, I need to come, daddy."
While Shouto worries that he knows nothing about being a good daddy, he can do this. He can give his boy exactly what he needs.
"Of course, baby," Shouto whispers, quieter and more breathy than he intends. He's closer than he thought he was.
Shouto's legs quiver and he drops to his hands and knees. The shift in position makes Inasa's dick feel deeper than before, and Shouto gasps at the sensation. He feels so full and so grateful for the man below him. His face comes level with Inasa's throat and he leaves wet kisses there as he thrusts against him. Harsher and more erratic now that he's so close, but neither of them mind.
When Inasa comes inside him, Shouto bites down, overwhelmed and filled in every glorious way he needs. He doesn't want this to be over but every touch feels like fire on his skin. Inasa hardly does more than touch his cock before he finds his climax, and he stays there for a long time, pressing open mouth kisses everywhere he can reach without moving. Inasa's hands smooth up and down his back, and he hums. Shouto smiles into the crook of his neck.
"Shouto?" Inasa calls to him, his voice tentative.
"Hmm?" Shouto can't be bothered to talk if there's no need, too sated and comfortable on top of Inasa.
"I wouldn't mind doing that again."
Shouto's laugh comes unbidden, but gently.
"Yeah, baby. I'd like that."
He closes his eyes and lets himself enjoy the warmth of Inasa's body around him. Inasa wraps his arms around him tightly, holding him close.
"Happy birthday, daddy."
Shouto laughs again, and kisses underneath his chin.
