Well this sucks. I didn't meet the deadline I had set for this. Adult life got in the way and it makes me angry. It's 2:36am right now and I have work at like 6am but oh well. This isn't as long as I had wanted this chapter. There is most likely a chance that when I have more time I will come back and add on more along with more editing. I'm just so fucking tired right now but yeah. There's one more chapter coming and yeah. I had hoped to have both the last two chapters out by christmas but it looks like the final chapter will be out before new years hopefully if adult obligations don't get in the way. I apologize if this entire chapter is shitty my brain sorta died.
One could say that things were a bit different after that night. Normal shenanigans happened about the house as usual except now small pranks were being pulled over the next week slowly escalating to a prank war. Unsuspecting residents getting up in the middle of the night to use the rest room to have buckets of water dropped on their heads instead of the intended victim, doorknobs to each others bedroom doors would go missing. The tension that had built up since Mephistos arrival disintegrated and was replaced with Christmas cheer from all around. Hidden by shadows there would be chaste kisses on faces which Shirou would scold Mephisto for the PDA when it first started. He didn't want to have to explain the situation quite yet to the other residents. He was sure that the twins wouldn't mind too much since they were still young and not really exposed to the idea of homosexuality in a negative or positive light, but they liked Mephisto enough it probably wouldn't bother them. Though it's not like his sons had seen him with a women either, unlike when he was in his teenage years and was known for flirting with all the girls in school.
The issue being Shirou didn't know if he was ready to approach the feelings he had for Mephisto. It had been a long while since they've been together in such a way, if together is the word for what they were at the moment. He wasn't really sure, but it was something that was always at the back of his mind.
A week had gone by since Shirou and Mephisto had sat down to their talk, but there was still yet another week until Christmas Eve. Preparations and plans had to be made for the holiday and for the boy's birthday. It had gotten to the point where the twins would tell anyone who would listen that their birthday was coming up. It was on the eighteenth when things really got interesting.
"I can so bake a cake!" The headmaster let out an exasperated huff as Shirous eyebrow rose in a questioning look.
"You? Bake? The closest thing I've ever seen you do is make instant ramen and that's a far reach from baking a cake." The discussion had been an on and off one throughout the week after Shirou had asked Rin and Yukio what kind of cake they would want for their birthday. Mephisto instantly had jumped to the idea that he wanted to make it as his gift to the twins but Shirou immediately poked fun at the idea of the demon baking. Though it was friendly banter that usually ended in a prank or two the conclusion to the discussion wasn't arrived until that night.
"Please." Mephisto held out the word for emphasis like a child as he squatted down slightly to be eye to eye with Shirou. Just the look Mephisto had on his face, and Shirou knew damn well he was only pulling that face to get what he wanted.
"Alright, alright enough of the pup faces. You can help make the cake but you're not making it by yourself." The purple haired man flashed a huge grin and it reminded him of the time he figured out that it was Mephisto who had been the small white dog with the pink bow and he hadn't spoken to him for a week. There had been a sputtered explanation from the at the time exorcist of how he thought he had known which was followed by Shirous silent treatment.
"You don't have to look so grumpy you know," he chuckled. The low sound pulled Shirou out of the past.
"I'm not grumpy and must you act like such a child? You're older than me but you don't act it." Shirou was still one for fun and games like when he was younger but since adopting Rin and Yukio he had matured some for the sake of at least trying to be a good parent. He thought he done a decent job so far. The demon king stuck his tongue out in a childlike manner, proving Shirou right.
"If acting like a child gets me what I want, then it is what I shall do." Typical behaviour of Mephisto, though it was a reminder that even if the exorcist hadn't done anything against the Vatican or any of the other exorcists that he was still a full fledge demon, someone who could turn on them and know all their weaknesses. Shirou tried not to think about this often because he basically grew up alongside Mephisto in his training, and it was a hard fact to swallow that there was even a small chance of that happening.
"Oi, you listening to me?" The principle must have been rambling on about something he thought was important by the look on his face.
"You dare ignore me as I poke fun at your flaws ol-" Shirou did the one thing he knew would quiet the other down; a simple kiss. If anyone who had known them in the past had walked in would probably fall into a fit of laughter. Shirou was still too short compared to Mephisto even with those stupid boots of his off, anyone else would probably freak out and shout; but at that moment Shirou was willing to take that risk. Something at that moment seemed different than all the other kisses they had shared over the last week. There was a hunger behind it, but it was gentle at the same time, every crevice and curve inside their mouths being memorized with their tongues. Hands gripped tightly at each other's clothes, nails dug into skin. Shirou let out a deep growl.
"You need to cut your damn nails." This made Mephisto snort in amusement. Shirou was short of breath, but as usual there he was, his face a mask that could hide the world's secrets.
"How about you make me." It was a playful challenge and one that the priest wasn't going to lose. He slid his hand down until he felt the solid part of his tail grabbed and pulled. The reaction he got was comedic. A sound caught between a groan and a yelp left Mephistos lips, the sensitive tail now unravelling itself from under the shirt and put itself into the comfort of its owner's hands.
"That wasn't fair!" A crack in the mask, whether if it was real or made up by Mephisto to make himself vulnerable he didn't know. Green eyes wide with feigned hurt and a pout he looked like a full grown child. A few moments later he found out it was all a ruse as the demon threw a swift kick to Shirous shin causing them to fall to the ground as they fought to gain control in their play fight. There was a creak and the two adults looked over to see Rin in the doorway, his eyes wide with confusion and mouth open. Mephisto was on top of Shirou, his legs on either side of the human's waist. One of the bespeckled man's wrists was in the loose grip of the other and both had dishevelled hair. It was Rin's older half-brother that broke the silence.
"What is it Rin?" His ability to act as if the situation they were in was completely normal was astounding. It was then that a bit of panic set in because Mephisto sitting on top of him.
"Are you guys playin'?" The little one asked. Of course he wouldn't really understand what was going on, he was but a child.
"Daddy and Mephy just got into a small fight, that's all." Well, it wasn't too far from the truth. He tried to avoid lying to his sons as much as possible since he already felt somewhat guilty about not telling them the truth about their past.
"Oh!" Rin walked over to them patted both their faces with a bit of force.
"You shouldn't fight, be nice! It's almost Christmas!" The grin that split his face could make anyone laugh; the two adults exchanged smiles with Rin.
"We'll be good now, I promise." Mephisto poked his nose and gave him grin.
"Now run along! Your father and I must finish our important conversation." Rin trotted off again out of the kitchen area to what sounded like to his room by the echo of his footsteps.
"We're in the middle of the kitchen floor so nothing." The glare Shirou gave would have any normal person back off; but Mephisto wasn't normal, he was immune to the look, found it amusing if anything.
"What are you afraid of old man?" There was the tone of challenge again, one that was met with a snort and they were soon wrestling for control. Though Shirou was a strong exorcist Mephisto still wasn't human and had the advantage of supernatural strength.
"You're a bastard, ya know that?"
"A bastard that you love." He stood up and wiped all the dirt off his clothes before he helped the clergyman up off the floor.
"Also I'm still want to do part of the cake, I can have Ukobach help me us also. But wouldn't it be fun? A family activity eh?" He left before Shirou got the chance to respond. Another few days passed with more mischief between the two, soon the children even joined in. Snow would be found in both their shoes, or maybe scarves would be found tied to things in random places through the house. There had been a morning where Rin made the scrambled eggs were blue, and they had found that Yukio had tied everyone's shoelaces together.
It was soon the 23rd and they celebrated the twin's birthday on Christmas since it was so close. With it only being a couple days till the holiday it was time to start doing prep work. The ingredients had to be bought in town and were usually bought on the same day so the whole household would go down to the shops. By then the shop owners knew when to expect the clergymen and to have things somewhat ready they all stared in surprise when Mephisto walked through the door with them, his white and pink clothing a giant contrast to black robes, and with Rin and Yukio trailing along with him too. When the couple brave souls gathered to ask of the tall purple haired man they townsfolk were informed that he was just an old friend of the church who was visiting. Mephisto easily towered over everyone at six foot four. The candy shop thought it was odd when Mephisto ordered large bags of candy which they scattered about in a hurry. He had no problem spending the money if the twins asked for something, which was extremely unlike him because Shirou could remember times where he would bug Mephisto for hours to buy something he wouldn't budge.
"You're being generous today for someone who gets stingy about even sharing instant ramen." They stood close to each other in the corner as Mephisto continued to pick out sweets to be weighed and bagged.
"Tch isn't that what your silly human holiday is about? Giving to others? Anyways, all you ever wanted me to buy was booze. Plus it is the little ones birthday soon. Shouldn't they be allowed to be spoiled?" He gave him a wink and a small smack of his butt and went to finish up his order. Shirou let out a hiss.
"You can't do something like that in public, it was uncalled for!" he grumbled as he followed him through the crowd to the counter.
"I see no problem with it; it is you who are making a big deal out of it and if you're not careful you might cause a scene yourself."
"Not a big deal for you who doesn't even live here. You can just go poof and your appearance here would be forgotten within a month. Don't cause any trouble for the sake of entertainment Mephisto." The sweets order was finished, bagged, and balanced in the demons arms. Once outside with a snap of his fingers he made it disappear to where Shirou assumed was back at the church. It had started to snow while they had been in the shop, Rin and Yukio ran about in the snow drifts.
"Come along now we must get back home if we hope to get the preparations done for tomorrow." The twins rushed back to the house, their giggles could be heard from all the way down the street. Once they arrived back everything was unpacked and the ingredients were needed for the cake. The ones that could be set out were left on the counter for tomorrow morning and the rest were put away. The little ones ran amok and the atmosphere cheerful, soon the sun set beneath the horizon and Shirou gathered them up and herded them to bed. They were hyper beyond belief {"Damn it Mephisto for buying them sweets"} and once they were under their covers he went back downstairs to make sure things were tidied up for the night. He had thought everyone else had gone to bed already until a pair of arms wrapped themselves around his waist while he was putting away dishes.
"You should relax." Mephisto leaned his weight against him, his breath warm against his cool skin. Shirou relaxed against him and let out a sigh.
"Having children doesn't allow you to relax often and when they don't need tending to then there's other things to do." A chuckle vibrated through him.
"Do you ever regret it? Taking them in?" he asked in a sombre tone, his hands made themselves busy by pressing out the wrinkles in his robe as he waited for an answer.
"There were times where it was difficult and I'm sure there will be moments in the future where things won't be easy but I don't regret it, not at all." Rin and Yukio brought a light into Shirous life, one that only taking care of children could bring.
"Hmm…" it was a small noise of confirmation that he had heard the priest and after that they stood there in silence as Shirou finished up washing dishes.
"Come, you really do need to loosen up that old body of yours Mr. Father. I really don't think it's healthy for you to be this stressed." He gave a gentle shove towards the living room; the bright moon showing through the window, snowflakes still came down. Shirou dropped down onto the couch and Mephisto plopped down into his lap, his long legs stretched over to the end of the couch.
"Relax," he spoke the words against the exposed flesh of the man below him, his hands slowly ran themselves up and down in a soothing manner along his spine. Cinnamon eyes met green and it felt like those years ago when they were together and things were completely different. Shirou leaned forward and pressed his lips against his other. They were cool to the touch and tasted of the sweets he had eaten this morning. Soon fingers were pulling at buttons and Shirous legs had found their way around Mephistos waist. Clothes were half way off and the demon had started to nip at the bared skin of Shirous neck and shoulders, delighted at the noises that were escaping the holy man's throat.
"M-mephisto we should p-probably go upstairs." His breath hitched as the devil being swiped his tongue from under his jaw to his ear. The looked he gave the priest went straight to his groin.
"If it is something you wish for." Strong hands grasped his torso and they were off the couch and moving to the upper floors of the house. Shirous legs were still wrapped around Mephisto and the whole way up his fiendish lover dragged his nails down his back, groans of pleasure left the human's mouth like music. They pushed their way through the door; Mephistos tail locked the door behind them. Shirous looked up at his long-time lover and he couldn't think of a single reason this was a bad idea.
