Shinobu snuggled up into Issei's chest, her lips bloomed a beautiful into a smile as she felt a certain warmth covering her.
The sun shined through the window onto her face, she opened her eyes to see, that she was covered by a leathery wing.
"What is this?" she asked no one in particular. She looked at Issei, who the wing was connected to. 'Could he be a demon? But he isn't affected by the sun.'
She bit her lips as a frustrated look came over her face. She wanted answers so she slapped her lover in the face.
It didn't hurt but did annoy him.
Issei woke up and saw that his wing was out. "Dammit not again!" he says, but he pauses and looks up at Shinobu who had a smile on her face.
He knew that smile, it was her angry smile.
"Dear why don't you explain yourself." says Shinobu, for some reason the smile both scared him and made aroused.
Scaroused.
"Listen I can explain, I'm not a demon I wanted to explain last night before you know." Shinobu released a sigh.
"Alright I guess I can. First things first, I'm a dragon, not a demon." Shinobu nods, she's fought literal man eating demons before, it shouldn't be a surprise other supernatural creatures exists.
"And secondly I'm not from this world." This Shinobu found hard to believe.
"You see I'm from alternate version of this world. With dragons, gods and Buddha's, hell demons exist however they don't eat humans." says Issei.
Shinobu was speechless she said nothing. Seeing this Issei sighed and grabbed her hand. The two then disappeared and appeared in his room, it was still night time.
"Wha! Where?" Issei placed his hand at her mouth. "Shhhh! This is my room. My Mom's might be still up." he says.
Shinobu calms herself and looked around the room. "This is?"
"My room it's current the year 20**, the Heisei period." Hearing this Shinobu's eyes widened.
...
Back in the demon slayer universe, Issei told Shinobu about his powers and a bit about his world.
And the most awkward part was telling her about his other lover.
"You have another lover!" said Shinobu pissed reasonably so. "Yeah she's fine with me getting other lover's though."
Shinobu's eyes narrowed. "Oh and why is that?" she asked.
"The same reason you limp every time you try to walk. I'll be getting stronger and so is my stamina. Not only that I want a harem a huge one! You can leave now if your not satisfied with that." says Issei.
Shinobu blinked and began to think about it, the flashy Shinobi had a harem, she doesn't have a problem with the concept of a harem itself, but what she was angry about was that Issei had another lover and not telling her.
She really and truly felt for Issei, the truth is she didn't mind having more girls. For some odd reason she couldn't describe. Honestly the prospect kind of aroused her.
An Harem to the beck and call of Issei.
Then she imagined it her and hundreds of other women with Issei sitting in a throne. Her pussy became soaked at the thought and she licked her lips, a blush coming onto her face.
"Fine I accept to joining your harem, however I shall personally judged the women you bring wether they be a suitable wife."
"Or they can be a maid like the demons I recruited." says Issei.
Hearing this Shinobu's face turned to a scowl. "What you made them your summons!" said the doctor, Issei placed a hand on her shoulder.
"Calm down Shinobu, you don't have to be angry. I recruited them to service me and my women, I already punished one. You can do whatever you want to the last one I recruited."
She didn't seem satisfied with just that.
"You can experiment as much as you want on her. Plus even if you kill her she'll just de-summon" says Issei. Yes his summons cannot be killed.
They will however have a cool down time before they can be brought back.
"Fine, I'll accept, however do remember I won't just let any woman have you." says Shinobu. "Yeah I think that's for the best, Aika probably wouldn't want to be bothered with crap like that." says Issei.
"Aika?"
"Yeah my first girlfriend, I do plan on having another girl who she's probably talked into sleeping with me."
Shinobu sighed and shook her head. "What a lust full man I've fell for. Fine then, however I want to meet her and you must explain everything to her before sex. From what I heard the supernatural world is extremely dangerous with beings that could erase Muzan in a single stroke."
"Yeah I get it, she needs to know what she's getting into." replied Issei. 'Especially since I have Longinus.' he finished in his mind.
