Within the days that had passed by, Tsuna found himself falling more and more for Belphegor; the blond was so sweet to him, always willing to learn proper manners and even a bit of kindness in order to make sure he was treating Tsuna right and that the blond would stay with him.

Bel, likewise, had never had someone treat him so well before, and he found himself wondering if maybe what he was feeling was akin to love – love wasn't something he had felt before, but then again, neither was the feeling of wanting someone around him every second of the day and night. Lussuria had tried to tell him he was being too clingy, but Bel disagreed; he simply was happier than he had ever been while he was by the brunet's side.

Tsuna knew he wasn't going to be the only one upset when he returned back to his own timeline.

"Belphegor…" The two were curled up in Bel's hotel bed, the sole occupants of the room; everyone else was out doing their own thing, leaving them in privacy. Tsuna leant up, drawing a passionate kiss from the man.

Bel's hand caressed the brunet's cheek, his obscured eyes as soft as a kitten's. He regarded his boyfriend with much love, his tongue dancing with Tsuna's. He moaned softly as he felt the younger's knee brush against his groin, instinctively pressing into the touch; it had been a while since he had felt anything but his own hands down there.

"Tuna-Fish…" Bel pulled his mouth away, moving it to suck against the younger's throat. He slipped a hand beneath the student's shirt, reaching up to caress soft nubs. "Tuna-fish, the prince… wants more…"

Tsuna's face was flushed slightly at the older male's ministrations, but he shook his head. "N-not yet, B-belphegor… Wait… a little longer…"

The blond nodded, knowing not to rush Tsuna. He bit down on the younger's neck, leaving a field of hickies as he licked up the drops of blood he had drawn. He could feel his pants tightening as the red fluid hit his tastebuds, but he didn't let it get to his head; he wanted to be with Tsuna willingly, not wanting him to feel forced in the slightest.

"B-belphegor…" Small hands pushed at the man's chest as Tsuna tried to sit up. He was understanding when Bel hesitated, and he smiled shyly as the other pouted; he had worked out early on that Belphegor had a blood kink. "Belphegor, I'm gonna make some lunch. Are you hungry?"

Bel nodded, licking his lips; he was indeed hungry, his appetite insatiable. He rolled onto his side, his obscured eyes following Tsuna's every movement as the teenager got off the bed and moved to the kitchen area; while Tsuna wasn't the best chief around, he still greatly enjoyed the younger's efforts – no one else had ever cooked for solely him before.

"Can we have sushi?" Bel lowered one of his hands down his body, resting it against his clothed arousal. He kneaded at the bulge slowly, rolling it against his palm every now and then. "Sushi is the prince's favourite~"

"If there's anything to make sushi with, sure." Tsuna blushed as he turned to look back at his boyfriend, embarrassed by the lack of shame Bel possessed; Bel seemed to have a very high sexual drive, so he was pleased that the other was waiting patiently for him – he had almost expected the other to go and sleep around in impatience, but that – thankfully – hadn't been the case.

Tsuna had heard rumours about Bel being sexually frustrated, as much as the man denied them; the brunet sincerely hoped he wasn't being a burden by forcing his boyfriend to wait.

"Belphegor, we're in luck." Tsuna laid out the ingredients for sushi on the counter, turning to grin at the Varia Guardian. He blushed darker when a soft groan answered him, not daring to look back; Bel had yet to understand why it was polite to refrain from pleasuring himself until Tsuna was gone, believing it was fine as they were together – Bel still had a lot to learn, but Tsuna appreciated that he didn't know any better.

Tsuna focused his attention on preparing lunch, humming to himself as he did so. He had been so caught up in his thoughts, he almost jumped when a loud, frustrated groan filled the air, accompanied seconds later by something heavy hitting the mattress.

"Belphegor?" Brown eyes looked over to the bed, finding Bel sprawled on it with a pout on his face. The thump the younger had heard must have been from his hand slamming down on the bed. "What's wrong?"

Bel sniffed, not looking at Tsuna. "It's no use; no matter what I do, it doesn't feel as good anymore! I can't even come!"

Tsuna didn't know how frustrating this must be, but he could see that Bel was visibly upset about it. He wasn't sure what could have caused it, but he did know he wanted to help.

Blushing, Tsuna put the knife he had been using to chop fish down on the counter as he made his way to the bed. "W-well… M-maybe I… could do something…"

Bel sighed. "It's okay, Tuna-Fish; the prince can handle it; he knows you're not ready."

Very shyly, Tsuna reached out, ghosting his fingertips against the exposed arousal, feeling it twitch beneath his touch. He could feel Bel's eyes on him, and it made his cheeks go darker.

"Just…" Tsuna cleared his throat, glancing to the side as he wrapped tentative fingers around the erection. "Just tell me what you like…"

Bel frowned before a genuine smile crossed his face. He nodded, reaching out to move Tsuna's hand himself as he simultaneously pulled the younger down for a kiss.

The blond wasn't sure he'd ever had an orgasm as great as the one Tsuna brought him, but he certainly knew why it was so great; for the first time in his life, there had been love in what he was doing – it wasn't meaningless sex with a whore; he had been touched by someone who loved him and wanted him to feel good.

If a simple handjob had felt so great, Bel couldn't wait to see what sex with Tsuna felt like.

~~XX~~

When Tsuna returned back to his friends that night, he was surprised when Shouichi asked to talk with him alone. He agreed, worried about what could have happened, but he had a feeling they were almost ready to go back to their own time.

"What's wrong, Shouichi?" Tsuna rubbed at his cheek, adjusting his jacket slightly.

The redhead spoke in an almost regretful tone, as if it pained him to admit this. "…I've fixed the machine, so… I know you have commitments here, so whenever you're ready, Tsuna."

Tsuna's frown grew further, worried about how Bel would take the news; it was no secret the other had grown attached and dependent on him, so would he cope alright if Tsuna were to suddenly leave him? The blond seemed to have gotten through Mammon's death just fine, but would this be the same or not? Would Bel just shrug it off with a sad look and a goodbye, or would he ask – demand was more his style, of course – for Tsuna to stay with him?

"I don't want to hurt him, Shouichi…" Tsuna looked to the ground, thoughts running amok in his head. "…Should I have become this close to him in the first place, knowing it wouldn't last very long…?"

Shouichi didn't know what to say, knowing he had put the Vongola through enough as it was.

Sighing, the brunet said, "I feel so selfish…"

"You're not selfish," the older male promised. "In fact, it was probably a good thing you did; give him a bit of love – I can't imagine love comes in bundles with Varia, after all."

Threading his fingers through his unruly locks, Tsuna said softly, "I'll go see him tomorrow, Shouichi; can you wait that long?"

"Take as long as you need."

"Thank you. I'm going to go to bed now. If you see Gokudera-kun and the others, please tell them that's where I am."

Shouichi nodded, wishing he could be of help – after the whole ordeal with Byakuran, it would be the least he could do.
