Ten years into the future, Tsuna had become the Vongola Decimo, and he was forced to hold a meeting with the Varia to talk about how he was going to be running things from now on.
The Varia's flight to Japan was supposed to be landing any minute now, and while Tsuna, Yamamoto and Gokudera waited for them, Gokudera couldn't help but feel excited to see his boyfriend of ten years again - their relationship had survived the months apart, mostly due to the fact that Bel was a self-entitled little shit and often abandoned missions halfway through in favor of taking the next flight to Japan to wind up on the younger male's doorstep without warning. The Varia had tried to stop this but, after the first couple of times that involved Squalo flying out to drag the Storm Guardian by the hair back to Italy, they quickly gave up when Bel started throwing temper tantrums and went as far as to bite his comrades - no one wanted that mouth anywhere near their bodies, not wanting to even imagine where it had been.
Now, as the Varia's flight number was called, the Vongola trio stood up, ready to collect them from the terminal. The six of them - Mammon, replaced after his death by Mukuro's prized student, Fran - eventually sauntered out amongst the hordes of fellow travelers. Unsurprisingly, Belphegor was in the lead, his usual grin wider than usual.
"Hayato-kun~" The blond ran to his lover's side, his long arms wrapping tightly around the silver-haired male's body. "Hayato-kun, the prince missed you so much~"
"I missed you, too, you big idiot - now get off me." Gokudera pushed his Storm counterpart away, embarrassed by the onlookers staring at them.
Bel giggled as he released the younger male, stepping back to admire his boyfriend. It had been two years since they had last seen each other, and the blond swore Gokudera became more beautiful every time he saw him.
"The prince has been lonely~" Bel purred before he leant down to steal a kiss from the now-taller male. "The prince has to masturbate every day when we're not together."
"You dumbass, I told you it's okay if you need to have sex." Gokudera shoved at the older male in a half-hearted manner. "You don't have to masturbate all the time."
"But Hayato-kun is faithful to the prince, so the prince will be faithful in return~" Bel shot his lover a grin that sent a wave of want up Gokudera's spine. "The prince has something to admit though; he had been drinking one night and accidentally got a blowjob. He promises it didn't go any further, though."
"How do you 'accidentally' get a blowjob, Belphegor?" Gokudera smirked in amusement.
"Because the prince had been drinking and he was horny, and he doesn't quite remember how it happened. Ushishishi~"
Gokudera just laughed. "It's alright, Bel. You know I don't mind as long as it's me you return to - it's so long we're apart, after all."
Bel nodded, giggling. "Hayato-kun is the prince's boyfriend~ He is loved very much~"
"I love you, too, Bel."
The two storm guardians turned around as Tsuna addressed them, finding the Varia gathered with the Vongola trio. Xanxus looked about ready to shoot everyone, while Yamamoto spoke.
"Xanxus wants to know if Bel is staying at the hotel with the other Varia," the dark-haired man asked.
"Nope~" Bel hugged Gokudera again, nuzzling his face against silver hair. "The prince is going to stay with Hayato-kun and have lots and lots of sex."
"Bel-senpai, what's sex?"
All eyes turned to the monotonous Varia Mist, wide with shock - the new recruit was young of course, but he lived with the Varia! How could he not know what sex was?
"I don't even know if the kid's joking or not!" Squalo growled, storming away from the group - Bel often called him a prude for being uncomfortable when topics like this came up, but he did not want to know about the others' private lives. They were private for a reason.
"U-um, well, Fran-san..." Tsuna shifted uncomfortably, not sure what to say.
"Ushishishi~" Bel licked his lover's cheek, his mischievous smile crossing his features. "Hayato-kun, can we show him~?"
"Absolutely not!" Lussuria cried dramatically, leaning down to pull the Illusionist against his chest as if to shield his questionable innocence. "Frannie is too young to be tainted like that!"
"Wait." The boy - Fran - pushed away from Lussuria, looking up Bel with emotionless eyes. "Is sex what you asked me to do to you with my mouth when you were drunk?"
Gokudera burst into laughter at these words while Tsuna and Yamamoto shared uncomfortable looks, no idea how old that kid was - and if he was even legal.
"How could you?!" Lussuria, as always, caused a scene, while Fran just shrugged, deciding the reactions to his question had confirmed it - now all that was left on the matter was research.
"Does he spit or swallow?" Gokudera asked once he stopped laughing.
"Mmm..." Bel tilted his head to the side. "...The prince doesn't remember. He was pretty drunk."
"Do you want me to refresh your memory when we get back to my apartment?" Gokudera lowered his hand, grabbing Bel's rear suggestively.
Bel giggled as he nodded enthusiastically, feeling his pants tighten. "Hayato-kun never sucks the prince off~! He's so excited~!"
"Shut the fuck up, trash!" Xanxus snapped, having to already deal with his subordinate thinking he could get away with masturbating wherever he wanted to at Headquarters - especially that one time when everyone was eating dinner together and the blond just spontaneously started stroking himself. "No one wants to hear you!"
Bel ignored his boss, his excitement too high to be contained. "Ooh, can the prince have a turn at being on top, too? He's never been on top before~"
Gokudera nodded, smirking, as he and Bel started walking in order to follow their group of the airport and to the limo Tsuna had brought to pick everyone up.
"Well, you are a pain in the ass, Belphegor. You're lucky I love you."
"The prince loves himself, too, Hayato-kun~"
"Tsch... Idiot." As they walked through the airport together, close enough for their bodies to brush against each other, Bel snaked his hand down into Gokudera's. The younger male accepted readily, squeezing Bel's hand before he claimed the blond's lips for his own.
If there was one thing Gokudera had learnt, it was that, long ago, he had opened his heart for just one other person - and that cuddly moron was the one now ranting in a loud voice about the things he thought about when he had just his hand for company. Needless to say, the majority of people around them quickly scattered after hearing about Bel's... graphic explanations.
Mmwhaaa... I love this fic. It's definitely one of my favorite ones in this fandom so far, considering it's not even my OTP. I don't know. I might write some one-shot side-ficsto this as it was so fun to write. I don't usually even write Belas a cuddly person, but it just seems so perfect with Hayato-kun. Mmwhaa... Now I'm just rambling. I hope you all enjoyed, and the epilogue was to your liking.
Oh, and regarding the implied B26, Fran'sold enough to be doing that with Bel- he just doesn't... have many needs, hence why he obviously didn't get the talk (or did, but it's Fran we're talking about here.)
