“Hey, baby,” James murmurs, coming up from behind and wrapping his arms around Regulus’ waist. He presses his face into the other man’s curls with a deep inhale.

Regulus turns around and meets James’ waiting mouth with his own. He can taste pomegranate juice on his lips.

It’s been a long day for the both of them. Despite being new Hogwarts alumni, their collective fortunes make it so that they don’t need to work, but James insisted on enlisting into the Auror program anyway. He’s gone for hours at a time, sometimes at night, to complete his training, and every day, he comes back dead on his feet.

Regulus, on the other hand, does no work at all. Waiting for James is work enough. They might be a bit codependent, but he couldn’t care less, honestly. His world spins when James is with him, and it stops when he’s gone. That’s all that matters to him.

“How was training?” Regulus asks between kisses. James is always extra touchy after work, always cuddling and kissing like his life depends on it. Tonight though, he’s practically lifting Regulus up off his feet with his arms as his mouth travels up and down his neck.

“Good. Fine. Tiring,” James replies, the words rushed like he can’t get them out fast enough. Regulus pulls back for a moment, raising a brow.

“Are you alright?”

“Very,” James mumbles. Regulus sucks in a breath as the other man’s teeth capture the soft skin of his neck. “A little tense though. Missed you a lot.” He runs his hands up Regulus’ body until they’re cupping his face and kisses him fiercely.

There’s something different about the way James is touching him tonight. They’re usually very intense, sure, but they’ve never…he’s touching Regulus like this time, he wants something more.

They’ve talked about it. Sex. Talked about what they’d like and wouldn’t like. However, Regulus neglected to mention a very crucial detail that seemed pathetic to say in the presence of James Potter at the time, and he’s been too prideful to bring it up ever since. Now though, with James touching him more and more insistently, a question burning between his palms against Regulus’ hips, he knows he has to.

“Baby…” James whispers below his ear. Regulus shudders and leans into his chest. That same unspoken question wraps around them like a blanket.

Instead of answering verbally, Regulus loops his arms around James’ neck and hides his face in the man’s shoulder, hopping to allow James to press his hands to his thighs and hoist him up. James carries him through the flat to their bedroom despite his obvious exhaustion from Auror training. He sets him on his back on their bed and props himself up over him, barely letting him breathe before going in for another deep kiss.

“James,” Regulus half-gasps as James’ hands begin working Regulus’ shirt off. “I haven’t — I’ve never —“

James stops immediately and falls to his side so that he’s laying beside him, concern in his eyes.

“What? Reg, are you…you know I don’t care that you’re trans, right? You know that, right? I promise, Regulus, I don’t —“

“It’s not about that.” Regulus shakes his head. He feels his cheeks flush hot and bright. “It’s not…it’s…James, I’m a virgin.”

James’ eyes go wide, and his perfect, perfect mouth drops in a way that makes Regulus want to crawl under the floorboards and never come out.

“Oh. Oh, Regulus, I’m sorry. I should have — Merlin, how did I not — I’m so stupid. I’m sorry, baby,” he rambles, frantically kissing Regulus’ face. “We don’t have to — shit, I’m so stupid —“

“You’re not stupid, James, I was just too embarrassed to tell you,” Regulus snaps in the firm tone he always uses whenever James starts to berate himself. “You’ve been with so many people before…I just thought…maybe you wouldn’t want me.”

James blinks furiously, looking wildly confused.

“Wouldn’t want you? Regulus, I want you more than anything. I don’t give a fuck about experience or — or whatever people told you the standard was,” he insists. Regulus shakes his head, but a smile tugs at his lips.

“Besides, “ James continues with a new spark in his eyes. “I’m a very good teacher.”

“Hm?” Regulus’ breath catches when he feels the pressure of James’ hand on his waist.

“If you’ll let me…” James kisses him again, more tender this time, and his hand snakes its way under Regulus’ pants.

“I’ll let you,” Regulus breathes. His heart pumps faster in agreement, let you, let you, let you.

“We’re not going to do everything all at once,” James says, which has Regulus feeling oddly disappointed. “You’ve touched yourself?”

“Yeah.”

“Good. We can go a bit further then.” James slides Regulus’ pants off, tossing them over his shoulder like they’ve offended him. Regulus’ legs are already shaking when James places his hands on his inner thighs and gently spreads them apart.

“Fuck, baby,” he groans.

Regulus’ fingers clench into a fist against the sheets as James attaches his mouth to his thighs, teasing at the skin with his tongue. James sucks dark hickeys into his pale skin, surrounded by bite marks that have Regulus swallowing back moans as they get closer and closer to the wetness between his legs.

“You still okay?” James lifts his head, and as he does, his glasses brush against Regulus’ folds. Regulus bites back a yelp, nodding feverishly.

“Yes,” he manages to get out. James doesn’t wait for further confirmation after that. He kisses Regulus’ hip, and then he lowers his head again, licking a slow line up between Regulus’ legs.

James goes at a leisurely pace, and Regulus feels every fucking second of it. James’ mouth sucks at the most tender of places, and when he bobs his head, the cool metal of his glasses teases Regulus’ clit with a shocking but welcome touch.

“D-daddy —“ Regulus whimpers the first time it happens, the word slipping out like it’s instinctual. He slaps a hand over his own mouth at this, thoroughly mortified, but James doesn’t miss a beat. He just hums happily, and his tongue takes on new enthusiasm as it flicks in and out of Regulus’ hole.

“Again,” he says lowly from somewhere deep within his throat. Regulus whines, his back arching when James licks at his hole again.

“Daddy,” Regulus whispers, “Daddy, please —“

“Good boy, baby,” James replies as he hooks his arms under Regulus’ thighs. Regulus can’t help the loud moan that he releases at James’ words. He wants to hear that over and over, wants to hear what a good boy he is, just for James.

“Fuck, Daddy —“ Regulus cries out much louder than he intended. James is properly sucking and licking at his clit now, swirling his tongue around it and lapping at it with quicker and quicker motions.

Regulus has no idea what an expert is actually like, but if he had to put a face to the word, it would be James. James and his masterful mouth and fucking excellent motions of his lips. The coil within Regulus’ stomach is so, so tight, squeezing and making him shake with need.

“Daddy, I’m — mm —“ Regulus’ voice breaks as James brushes his teeth against his clit, just enough to send a shock through him. “Coming,” he barely manages to gasp out before he’s rocked with the peak of his pleasure, his orgasm ripping through him in what feels like endless waves. James eats him out through the whole thing until Regulus tugs him away by the hair.

Tremors still spasm through Regulus’ body as he draws James up to his lips for a tired kiss. He can taste himself when their mouths meet.

“So, was I a good teacher?” James inquires with a smug smile. His lips are swollen, and Regulus suspects his might be as well.

“Teach me again tomorrow,” is all Regulus can breathlessly say in response.

James chuckles and pulls him closer, guiding him so that his head is against James’ chest.
