The end and a new beginning.

A teenager named Yogiri Takatou of average height drifts about aimlessly in the never ending void.

Around a few years ago he had decided to put an end to the universe he had resided in for so long. He had been reincarnated there so many times that it was all such a bore.

There were no beings of significant strength and the concept of supernatural power was only myth.

This world though, did have something that he considered within his top 5 of utmost importance, the existence of anime/manga and video games.

Still, that wasn't enough for him to spare them as everything and everyone inhabiting the universe had ceased to exist along with the universe itself.

He had planned to find a reality where those same anime and manga were real. In his time that he had tried to remain as human as possible his excitement over the idea of an isekai/ fantasy adventure was real.

'I'll make, sister do it." Yogiri spoke before the word 'die' entered his mind.

As soon as his will was expressed, all the seals that acted to restrain his power ceased to exist.

'Die.' Yogiri though again and just like he commanded it did die.

As to what is, is. Reality itself. All laws, creation, concepts, everything. It all ceased to exist.

Well that was until a blinding light suddenly made it's way into the void and before Yogiri knew it a beautiful girl with silver grey hair and similar colored eyes appeared before him.

She stood around 5'6 and had a body only describable by the word 'god.'

Adorning her was a full white dress, that left her cleavage exposed.

"Why must you destroy all I have created every time you wish to see me." The girl who actually produced light spoke with displeasure.

This girl was the 'sister' of Yogiri but unlike him her dominion was creation. She was responsible for everything that ever was.

Even if they weren't necessarily blood-related, they existed together in nonexistence.

"How else am I supposed to meet you?" Yogiri spoke watching as the girl already beginning her creation yet again.

The two now stood on a platform of stone. By now she had already recreated all concepts, laws, and now the big bang and simply sped up time around them as to make the process faster.

"Calling my name would be enough." The girl spoke as she turned her attention away from her creation and looked at the teen, the only existence/nonexistence she had no control over.

Thankfully it was the same for him.

"Boring," Yogiri spoke before his gaze caught sight of the form his sister had taken on.

"Y'know sis, for someone who laughed at me for hanging among humans you sure don't seem to be much different," Yogiri spoke before approaching and brazenly groping the girl's ample breast.

"Call me Mio, and yes they do seem to have grown on me." She nodded as she tried to ignore the eaves of pleasure washing over her. Her body wasn't skin deep, she had made sure to add all the internal functions as well.

"Clearly." Yogiri continued feeling around the girl's body before his impatience won out and he pulled the girl's dress over her ass.

The girl's perky ass was revealed to him in all its glory along with her pink pussy that wasn't constricted by underwear.

"So what is your point in calling for me?" Mio asked as she felt a finger invade her virgin depts.

"Hold on a second." Yogiri said before pulling out his finger. Seeing the fluid that followed after him he smiled before standing back up.

In seconds his pants were discarded and without out any warning, he plunged his dick inside her virgin cunt.

There was no groan of pain, not any blood. Instead, Mio screamed out in ecstasy as she felt herself suddenly filled.

She wasn't ashamed to admit that she was anticipating this event. Apart of having a human body came with human desires.

Unfortunately, she wasn't interested in fucking any of her creations. This only left one person who could fill the role. And yes, he filled it very nicely.

As Yogiri continuously thrust in and out of the girl he began to state his reason for calling her.

"I'm bored again."

"Nnn~ Of course you are. AHHHH~ right there~." Mio moans louder as her cervix was knocked against.

"How about this time you surprise me?" Yogiri grunted as he flipped the girl around and pushed her to the ground.

"Fine, whatever. Just keep fucking me." Mio grunted in dissatisfaction as she, now laying face up spread her soft thighs while at the same time her dress vanished from her body, letting her E-cup breast bounce free.

"Works for me." Yogiri went down to his knees as he put the girl's sexy legs on either side of his shoulder.

As he slid in again he used his right hand to press slightly down on her lower stomach. The pressure was just enough that her G-spot was being pressed on by her bladder.

The reaction was immediate as Mio came hard around his cock. Fluid sprayed straight to his chest as her legs wrapped around his torso and her back arched.

Yogiri not yet reaching his release didn't give the girl a moment of rest as he began yet again thrusting into her depts.

(7 Eons later)

By the time the two had decided to stop their multi-billion-year-long fuck fest Mio had already created a multiverse just as she had done so many times before.

She had also done as Yogiri asked and created something to entertain him.

"Well, that was nice." Yogiri stretched himself as he overlooked the countless planets that aligned their current universe.

"You're so impatient, another trillion years would have been nice." Mio who was still unclothed spoke as the most recent load of cum dripped down out of her cave.

"Maybe another time, if it was up to you I would be here for an eternity." Yogiri kicked at the naked girl who lay against the stone platform.

In those billions of years, she didn't even bother to make a suitable bed.

"Whatever, your 'surprise' is ready. I made sure it fit your perverted teenage desires very well." Mio while pouting stood up.

"Says the one who was begging me to fuck her harder." Yogiri scoffed as he found clothes suddenly appearing on his body.

Mio didn't even reply as instead the stone platform they were on previously transformed into that of a modern western room albeit without walls.

In the upper middle of the room was an extremely soft bed that Mio uncaringly jumped onto.

Across from her a flat-screen TV suddenly came into existence and on it was a familiar sight of two people lost in carnal pleasure.

Mio, uncaring of the presence of Yogiri mindlessly used her hands to masturbate to the scene of her and her brother fucking.

Yogiri stood still with an expressionless face as he gazed at the shameless girl.

"Well, Mio. I think it's about time I go." Yogiri coughed to get her attention.

"Yeah, yeah. Have fun bro. Leave some space in your bed for me, k?" Mio without even looking his way spoke before Yogiri was enveloped in a golden light and suddenly disappeared.

Just like that the sibling pair of the beginning and the end once again separated.
