Mukuro trusted Belphegor, so it was no surprise he often left the older teenager home alone with Fran. Fran never complained about this, so the blue-haired male felt comfortable about leaving them alone together; sure, Belphegor had his problems, but Fran needed to learn how to handle him.

Turning over the box he held in his hands, Mukuro frowned as he looked over it reproachfully; he had been out getting food for them all, and though none of them had eaten this particular type of snack before, he had heard good things about it. He didn't have any worries of the smaller two not eating it as they would both eat anything they could get their hands on, but he certainly hoped it tasted good or else he wouldn't want it.

With a sigh, Mukuro slipped the box back into the plastic bag as he walked through the car park belonging to the other residents of his apartment complex. He entered the ground floor before making his way over to the stairwell, climbing it and walking out onto the veranda corridor in silence as the cold wind batted at his lanky body.

The teenager greeted one of his elderly neighbours politely as the woman passed him, holding the door open for her before he continued on his way, deciding that a sleep would do him some good when he got home; Belphegor had kept him up for most of the night, the older male struggling with his insomnia worse than he had in a while.

Finally, stopping outside of his apartment, Mukuro fished the key from his pocket. He could hear Fran from inside, the boy crying out loudly as if he were in pain. "Fran?!"

Jamming the key into the lock, Mukuro was quick to unlock the door and step inside. He dropped his shopping by the front door as he kicked it shut, hurrying into the bedroom. He wasn't surprised when he found the smaller males on the bed, clothing discarded carelessly on the ground as the blond crushed Fran to the bed with his heavier body.

"Belphegor!" Rushing over to the bed, Mukuro grabbed a thin arm, trying to tug the older teenager away from Fran. "Belphegor, stop! You are hurting him!"

Bel groaned as he turned to look up at his boyfriend, scowling. He had stilled his body, but it was clear he wanted nothing more than to keep thrusting away inside of the boy. "I'm trying not to! Get off my back!"

It was Mukuro's turn to frown as he watched the smaller male start moving again, surprised to see that Belphegor was being careful with Fran – never before had the blond cared about hurting him or not, so why now…? Why Fran…?

Moving to sit on the bed, Mukuro pulled Fran onto his lap. He caressed the boy gently, smiling down at him as tear-filled emerald eyes fixed on him. "Is this too painful for you, Fran? Would you like for it to stop?"

Shaking his head, Fran tried to put on his bravest face as he sniffed back his tears. His quivering body told a different story, but he said, "I'm okay, Master… It's… different…"

Patting teal hair, Mukuro leant down to claim Bel's lips in a kiss. "Did you ask for his permission first, Belphegor?"

The blond shook his head, grunting as a particularly powerful wave of pleasure washed over him. "Why… would I…?"

"Does this scare you, Fran?" Just wanting to make sure his charge was okay with what was happening, Mukuro wished he could take away the younger's pain, but he knew that when – or if, as he truly doubted Belphegor was even searching for it – the older teenager found his spot, the boy would be overwhelmed with pleasure.

Fran shook his head, his breathing heavy as he tried his best to trust that Belphegor wasn't doing anything wrong to him. "N-no, Master… I'm alright… I promise…"

"Spread your legs a little wider." Reaching out, Mukuro pushed at the boy's thighs, giving more room to Belphegor. "That's it. Now hook one over his shoulder; it will allow him to slide easier. You have only a very small body, so you must give him as much access as you can."

Fran yelped and cried out as a loud squelch filled the air, tears rolling harder down his cheeks as rivers of blood stained the white bed sheets beneath him. He sobbed and whimpered as the pain became worse, and though he wouldn't admit it out loud, he was grateful that Mukuro was stopping Belphegor, forcing the blond out of his body.

"Fuck off!" Belphegor growled as he shoved at his boyfriend, wanting nothing more than to finish himself off into the boy who was so impossibly tight around him. "I'm not done yet!"

"Belphegor, stop." Mukuro used the tone he reserved only for when there was no room for argument, not about to let Fran get hurt worse; he didn't like the blood that was seeping from the boy, and he didn't care if Fran had consented or not; it was clearly only hurting him, and could have caused severe damage if it didn't stop.

Fran moaned, lying limp in his guardian's arms as he was picked up from the bed and carried out onto the couch. Belphegor was left behind, forced to finish himself off, but Mukuro didn't care; he wouldn't stand for the blond showing blatant disrespect for the fact that the teal-haired male had been placid enough to give himself to Belphegor, even though it was only hurting him.

"Master…" Rubbing at his wet eyes, Fran snuggled in close to his guardian. "That… really hurt… I don't understand… You two do it together, but… Why? Why do something that hurts so much…?"

"Fran…" Sighing softly, Mukuro knew he should have talked about this with his charge before he so much as started to kiss the younger. Standing up from the couch, the blue-haired teenager went to the bathroom and grabbed a heat-pack. He put it in the microwave and, once it was nice and warm, brought it over to Fran. "Rest this on your rear, please; it will help with the pain."

Fran did as he was instructed, his eyes fixed on the stronger male. "…"

"Belphegor and I do that because it feels good for me, and it is something we both greatly enjoy doing," Mukuro said softly, threading his slender digits through teal hair. "I believe that your body is just too young and small to be able to feel the pleasure we can, and I wish that Belphegor had waited until you could handle it."

"Do I really have to tell an adult that he did that?" Fran sounded so confused, it broke Mukuro's heart. "You said I couldn't tell anyone, but Squalo said I have to. Who do I listen to?"

"You listen to me, Fran," Mukuro said, a hint of demand in his voice. "I do not care that Squalo told you to tell people; you do not tell anyone, or else all of us will be in trouble. Do you understand?"

Fran hummed before he nodded. "Yes, Master. I won't tell anyone."

"Good boy." Leaning down to kiss the younger's forehead, Mukuro smiled. "I love you, Fran."

"I love you, too, Master."

~~XX~~

"Are you still sore, Fran?" Looking down at the boy curled up on his lap, Mukuro ran his hand down the boy's arm. Fran yawned as he nodded, staring at the blond laying on his stomach against the hardwood floor, a few textbooks and notes scattered around him as he chewed on the end of his pen.

"If Bel-senpai is older than you, why is he in the class below you?" Fran had always wondered about this, but he had never asked it before. "Is he really as stupid as he makes himself out to be?"

"Kufufu~" Shaking his head, Mukuro glanced over at his boyfriend, chuckling as he found the smaller teenager glaring at them. "No; Belphegor is a genius, Fran; it is just a shame he and Rasiel were forced to start their schooling very late."

"Why?"

"They never went to school until they were adopted; their parents were very… negligent towards them. Well… Towards Belphegor, they were; they treated Rasiel very well."

"But why are they still lower than you, Master? Shouldn't they have been bumped up?"

"No, because when they were first taken to school and given a test to see if they would be able to cope in a higher grade, Rasiel passed it easily while Belphegor struggled very much, having never been taught how to read or write, much less do anything else learnt in schools. Timoteo, Xanxus' foster father, the one who had adopted them, had requested for Rasiel to be placed in the same grade as Belphegor so that he was not alone and had someone he knew with him. Even though Belphegor learnt very quickly, he could not skip any grades; he is forced to go through them all individually."

Fran nodded, absorbing this information into memory. "Can I go to school, too, Master? It gets really boring staying here by myself all the time."

Mukuro frowned at this question, not wanting to share his precious Fran with anyone. "…We will see, Fran…"

"I love you, Master."

"I love you, too."

I might do the time skip next chapter, unless anyone can think of anything I haven't touched upon enough or think I should do first.
