A/N: Here is the NSFW sequel to the previous oneshot. I wrote this a couple days ago but I forgot to post it. I'm sorry.

I hope y'all can enjoy this even though it isn't Valentine's Day anymore :'3

"Mmm…we really should move…"

Twining their fingers, Chuuya holds Dazai's hands down to the ground, kissing him deeply and lovingly. He can taste his homemade chocolate on Dazai's tongue, and Dazai's sweet sounds are driving him crazy.

If only they weren't on the kitchen floor.

"Yeah…we should…" Dazai murmurs in agreement, although reluctant to have Chuuya get off of him. But they have no choice if they want a better place.

Chuuya rolls off of Dazai, standing up slowly, reaching his hands out to pull Dazai to his feet as well, then he pulls Dazai in close, practically able to hear his heartbeat. "You're so pretty, Osamu…mmm…"

Chuuya immediately puts his hands on Dazai's shoulders and pushes him down against the one spot on the kitchen counter that has no chocolate on it, laying Dazai down over it. Chuuya leans in and connects their lips again in another hungry kiss, this one even more hungry than the last. Their tongues intertwine and Dazai's noises are even louder.

"Want some chocolate…?"

"Yes please…"

Chuuya breaks away from the kiss and reaches for a piece of his homemade chocolate candy, placing it in Dazai's mouth, grinning at how red Dazai is. "Isn't it delicious?"

"Mmm…mhm…"

Chuuya retrieves the brownie Dazai gifted him. He takes one last look at the crude letters that say, "I LOVE THAT DICK ♡ " and rolls his eyes.

He places the brownie box on Dazai's stomach and grins at him. "Won't you feed me this delectable brownie you bought me?"

"Of course…" Dazai whispers. "And then…may I give you my second gift?"

"Absolutely."

Dazai sits up, holding the brownie. He takes pieces of brownie and feels his heart throb every time Chuuya sucks on his fingers when he takes the piece. He feels so warm today—although it's no mystery why.

"Alright, I think that's enough for now," Chuuya declares when he's eaten about a third of the large brownie. "I will say, despite the crude message on it, the brownie is delicious."

Dazai smiles at that, although not as wide as he normally would, due to the fact that his heart is pounding so hard that he can hear it.

"Now…I think I'm ready for this other gift you mentioned. Would you give it to me?"

"Oh…absolutely."

Dazai scurries off and goes up the stairs, Chuuya watching. He's eager to see what Dazai has in store. He has an inkling of an idea, but won't know until—

"I'm ready~" Dazai loudly cooes from the top of the stairs.

Chuuya's eyes widen a bit. How did Dazai get ready so fast? He decides to not dwell on it. 

Chuuya takes a step towards the stairs, but then gets an idea. He steps back and grabs the unfinished plate of chocolates, as well as the bowl of liquid chocolate with a spoon. He licks his lips, hoping his guess is right so he gets to use these in the fashion he has planned.

Chuuya removes his apron, leaving it puddled on the floor, not caring enough to properly hang it right now. He heads up the stairs and to the bedroom—

And sure enough, there Dazai lays, wearing very scanty pink and red lingerie. It was very lacy and had hearts that very poorly covered anything private. Of course, though, since the lingerie was not made to be worn by a man, the bottoms do a very poor job at concealing Dazai's arousal. So poor that it pushed the fabric aside (or Dazai very possibly pulled it aside), his dick sticking out of them.

"O-oh wow…you look…" Chuuya takes a deep breath, his pants suddenly getting tighter.

"I look amazing, right?" Dazai muses, tugging the elastic of his thigh-high stocking, letting it snap against his skin. "C'mere, Chuuya…I wanna prove to you what I had put on that brownie."

Without any further persuasion, Chuuya flocks over to the bed, placing the candies and liquid chocolate on the nightstand, immediately starting to undress.

"What's the chocolate for?"

Chuuya looks over at the chocolate, then back at Dazai, a slight smirk forming on his lips. "Oh, you'll see."

Soon enough, Chuuya is in nothing but boxers, and reaches over to the nightstand to open the drawer—when Dazai grabs his wrist. "N-no condom tonight, Chuuya…I wanna feel all of you in me."

Chuuya's heart throbs and his dick twitches. He could never refuse something like that. He looks at Dazai, eyes now sprinkled with concern. "Are you…sure?"

Dazai nods. "Never been more sure. Please, Chuuya…I want you to come inside me."

Chuuya bites his lip and sucks in a deep breath, feeling that statement turn him on even more. He only takes lube out of the drawer instead and then removes his boxers, Dazai's eyes immediately locking onto Chuuya's dick, as expected.

Chuuya opens the bottle and squirts some in his hand. He rubs it between his hands and fingers, warming up the viscous fluid to a more pleasant temperature. 

He starts by putting his hand around his dick, jerking it to lube himself up. He sucks in a deep breath, now realizing just how aroused he is. He falls back off of his knees and starts jerking himself off much more intensely and roughly. "F-fuck," he murmurs, eyes shutting. His other equally wet hand grips onto the sheet, staining it with lube, breathing heavily and hotly.

Normally, Dazai would whine about Chuuya doing such a thing and not fucking him instead, but Dazai is also too aroused to think of much else than the glorious sight before him. He puts a hand around his own dick, and starts jerking off as well.

Dazai's head falls back onto the pillow, moaning at the wonderful sensation. It's been awhile since he and Chuuya last jerked off together. Dazai can't recall a time of them doing that since after Dazai left Port Mafia.

Chuuya's eyes open and he starts feeling warm. Right as he does so, he sees Dazai was jerking off as well, and comes right then while moaning out Chuuya's name.

Chuuya takes a deep breath and decides that if Dazai got to come, so can he. "Osamu," he calls, voice soft and seductive. "Look at me."

Dazai slowly looks up, still basking in the delicious post-orgasmic haze. He moans at the sight of Chuuya getting off, clenching the sheets to keep himself from touching himself again. He wants to wait until they actually begin before he does that.

Chuuya leans back, releasing the tension in his body, thusly reaching his orgasm and coming as well, biting his lip hard to keep from moaning or falling onto his back.

He takes a few deep breaths, regathering his bravado, then rises back to his knees, putting his hands on Dazai's thighs, looking down at him, a ravenous look in his eye. As if he's ready to break Dazai.

"Alright, honey. After that detour, are you ready for the real games to begin?"

Dazai nods, more eager than he's ever been.

"Wonderful."

Chuuya promptly pushes into Dazai, pulling a large moan out of him, causing his back to arch even though Chuuya has done nearly nothing.

"Woah woah, relax, Osamu. I'm not fucking you just yet."

Dazai gives Chuuya big pouty eyes. "Then what are you gonna do?!" he whines.

"A wonderful thing called foreplay," he teases. He then reaches to the nightstand and grabs the bowl of liquid chocolate, stirring it carefully.

"What are you…gonna do with that, Chuuya?"

Chuuya takes a scoop of the chocolate and starts moving it to Dazai's face, grinning.

"W-wait, Chuuya, that'll—"

"Don't worry, Osamu, it's far from hot."

Chuuya puts the chocolate in Dazai's mouth, and it is indeed a nice temperature. Dazai closes his eyes and licks his lips.

"Is it sweet?"

Dazai nods slowly and happily. "Mmm…mhm…"

"Then I think I'll try it, too."

Chuuya takes a heaping spoonful of the liquid chocolate—but instead of putting it in his mouth, he lifts up Dazai's lingerie top to completely uncover his skin, he drizzles it all over Dazai. On his clavicle down to and including his nipples.

"Oops, looks like I spilled some chocolate," he cooes jokingly. "I should probably fix that."

Chuuya leans down and starts licking up the chocolate very slowly. It is very sweet, but even Chuuya's homemade chocolate isn't as delicious as the taste of Dazai. Chuuya's tongue travels along Dazai's clavicle, licking up all the chocolate in its path, traveling down Dazai's pectorals to his nipples.

Chuuya's tongue swirls around Dazai's nipple, licking up all the chocolate on it. Even after the chocolate is gone though, he doesn't move away. He starts kissing Dazai's nipple, then latches on and starts to suck on it.

"A-aah, Chuuya…" Dazai moans. "I think you got all the chocolate…"

"Mhm..."

Chuuya simply keeps on sucking for awhile, pulling many noises out of Dazai due to how sensitive his nipples are. He knows he got all the chocolate; he just wants to keep doing this whether or not chocolate is there. Chuuya loves seeing what such contact can reduce Dazai to. He loves seeing Dazai become mush, putty, pliant in his hands—and only for him. Chuuya. And nobody else.

After a blissful eternity, Chuuya switches to Dazai's other nipple, doing just as he'd done before. He starts licking up the chocolate all around it, then latches onto it as well and starts to suck on it. 

Dazai moans again, throwing his arms up above his head. Chuuya's hand then goes to Dazai's other nipple and he starts pulling and tweaking it, pulling an even louder moan out of Dazai. "O-oh, Chuuya…mmn…aaah…"

Chuuya chuckles against Dazai's chest, absolutely loving the sounds Dazai is making. He loves making Dazai feel good. He loves knowing he gets to do this, gets to see this side of Dazai that nobody else gets.

He pulls away from Dazai's chest and licks his lips, smiling down at Dazai. He reaches over to the nightstand again and grabs a tissue, wiping away the miniscule remnants of chocolate, leaving Dazai nice and clean.

"Such a good boy," he cooes sweetly. He takes one of the chocolates out of the plate and puts it against Dazai's lips. "Want it?"

Dazai quickly takes the chocolate in his mouth, eating it eagerly. "Mmm…Chuuya's chocolate is so good…"

Chuuya cups Dazai's cheeks, squishing them gently and sweetly. "I'm glad you like them so much. They are all for you, after all."

Chuuya leans in and kisses Dazai, quickly sliding his tongue into his mouth, tangling them together. Dazai's mouth tastes like exquisite chocolate, of course.

"Mmm…I love you…

Dazai kisses back eagerly, letting out soft whimpers of happiness and pleasure. "I l-love you too…now…please fuck me, Chuuya…wanna feel your big dick thrusting in me…wanna feel you come inside me…d-don't wanna walk tomorrow. Please…I love you…I love how good you feel, too. Please…want your huge dick…please…"

Chuuya pulls away from the kiss and cocks an eyebrow, feeling all those words turn him on even more.  "Goodness, Osamu. You're suck a size queen."

"Mmm…I blame you. I didn't care about big dicks until I met you. Now, I…I don't want anything else. Please, Chuuya…I'm already begging."

Chuuya chuckles darkly, the one that lets Dazai know something wonderful is coming. "Well, since it's Valentine's Day, and you asked so nicely."

Chuuya puts his hands on Dazai's shoulders and finally starts moving. He starts slow, but Dazai is already moaning loud.

"See why foreplay is so wonderful?" Chuuya purrs. "You're even more turned on now. Doesn't it feel so good?"

Dazai throws his legs up in the air, and throws his head back. "Y-yes! Amazing! Aaaah…so good, Chuuya…so good…I love you…!"

"I love you too, baby."

Slowly, Chuuya's thrusts get more aggressive and rough, causing Dazai to moan even louder. Chuuya's grin starts to falter as the unbridled pleasure starts taking ahold of him. He hadn't felt this amazing in a long time, not without aphrodisiacs.

"F-fuck—"

Chuuya starts moving more erratically, and can't hear anything but Dazai's moans.

"I'm…I'm gonna come inside you now, Osamu…okay?"

"O-okay! I'm g-gonna come, too!"

After that, Chuuya comes, filling Dazai to the brim, letting out a low moan. Dazai comes at almost the exact same time, eyes rolling back, moaning silently, back arching. Then they both fall flat, Dazai falling on the pillows and Chuuya falling on Dazai.

"Ah…oh…that was so good…" Dazai wraps his arms around Chuuya, holding him close. "Ch-Chuuya…came so much…"

Chuuya lifts his head to look at Dazai. "It was so good…mm…"

Chuuya kisses Dazai again, although it's less of a kiss and more just touching of tongues, as if they've been addicted to each other's taste all day.

"You know…this lingerie looks so good on you…you're so pretty…"

Dazai's eyelids flutter. "Thank you, Chuuya…I was hoping you'd like it…"

Chuuya rolls off of Dazai after that, laying beside him, taking deep breaths. He looks up at the ceiling, still a bit dazed from how intense that was. "I love you."

Dazai adjusts his shirt, pulling it back down to cover him—although it didn't do much of a job with that regardless. He smiles to himself. He doesn't think he could possibly be happier. "I love you too, Chuuya."

Chuuya closes his eyes as well. He too, is elated. "This has definitely been the best Valentine's Day I've ever had."

Neither of them had really had remarkable Valentine's Days to begin with, but the point still stands. This has by far been one of the most amazing days in general that they have ever shared. "I couldn't agree more," Dazai whispers sweetly. He never thought he could be so in love—and yet here he is. And he really has never been happier.
