Lucy awoke and climb out of bed. She walks to her kitchen and grabs a cup of coffee. She took a sip and started to think about her and Danny. They had been together for a week, and Danny asked her out on another date this weekend. She thinking that it would be time to tell him. She couldn't keep her horns and tail hidden forever. She was still afraid of him dumping her if he found out. But she knew it was better for her to tell him instead of him finding out. She sighs and picks up her phone. She needed some advice. She calls the number and waited.

"Hello?"

"Hey, LJ, sorry to wake you." She said.

"Sis? This is a surprise. What's wrong?" LJ asked.

"I want to tell Danny the truth. I wanted to tell him what I am. But, I'm afraid." Lucy said.

"Afraid?" LJ asked.

"Yeah, the youngest daughter of the Devil is afraid. I must sound weak." She said.

"No, Lucy, you're not. Fear might be a human trait, but we more human than we give ourselves. Just know, even if he doesn't want to see you after this, just know I'll be here." LJ said.

"Heh, you always were the nice one." Lucy giggles.

"And Dad hated it." LJ chuckles.

"Tell you what, let's both tell them. We always face things as a family." LJ added.

"Alright. I guess we can make it a double date." She said.

"Heh, Jazz really enjoy our date. I'm sure she won't mind a second one." LJ said.

"Did you get her in bed?" Lucy asked.

"Nope. I wanted to take my time. She the first girl I even like, and I wanted it to last." LJ said.

"That's a first," Lucy said, smirking.

"Oh, shut up," LJ said.

Lucy ended the call since it was getting close to school time. The talk with her brother really made her feel better, but she was still worried. She took a breath and got ready.

At the Fenton's, Danny walks downstairs and notices Jazz looking at her phone and was surprised.

"What's up?" He asked.

"LJ wants me and him to join you and Lucy for your date. Saying that there is something they both want to tell us." Jazz said.

"Really? Like a double date?" Danny asked.

"Yeah, weird." Jazz said.

"Well, if it something they need to tell us, then let's hear them out," Danny said.

"Sound fair." Jazz said.

"So, Jazz? How was your time?" Danny asked.

"It was great! LJ was a really great guy! I can see myself with him." Jazz said.

"Sounds like you're ready to marry him." Danny teases.

"Danny..." Jazz said as he laughs.

"I'm kidding. Plus, he cool. Mom and Dad are fine with it and so am I." Danny said.

"Thanks, little bro." Jazz said before they got ready for school.

School rolled around, and the day went okay. Both Danny and Jazz wonder what their boy/girlfriend wanted to tell them, and Danny did try to get Lucy to at least give him a hint.

"Let's just say that it going to be a huge shocker." She told him.

Jazz felt sad that LJ didn't come to the school, but the whole school heard that she and the new guy went on date. Many girls couldn't believe it, and some try to talk Jazz down about not being the girl he should have. But Jazz ignores them. She knew LJ was honest with her. She was sure whatever he had to tell her, she would listen.

School went by pretty fast, and so did the rest of the week. Danny still spend the nights are Lucy's house, and Jazz was started to do the same with LJ. Both Devilman siblings make sure not to rush into anything because they want to tell them first. The date night appears and both Danny and Jazz started to head out.

"Alright, mom and dad, we're out on our dates. " Jazz said.

"Have a good time you two! And remember about the birds and bees." Jack shouted.

Both Fenton siblings flinch at that. During the week, Jack decides to tell them about "The Birds and Bees". Both siblings were blushes throughout the week after that. They knew not to rush into anything since it was their second date.

"So, where are we going?" Danny asked.

"LJ invited us over to his house. Lucy is already there, making some food for us." Jazz said, recalling the text from him.

"Well, I did try to see what else I could get that they wanted to tell us, but Lucy said to wait until our date," Danny said.

Jazz sighs. She did ask LJ as well, but never got an answer. They walk down the street before they spotted Dash and Paulina.

"Well, look what we got here, Freaky Fenton and his freaky sister," Dash said.

"What brings you two out here? Wait! Don't tell me, you two finally know how worthless you are." Paulina said.

Both Danny and Jazz rolled their eyes.

"If you must know, we are heading for LJ's place for our double date." Jazz said.

"And you two aren't invited," Danny added.

"What? Come on! We are fair better than you!" Paulina said.

"They why are they dating us?" Danny smirks.

"You are so dead, Fenton!" Dash said.

"Hands off, Dash." Jazz said, getting in front of him.

They soon hear a car horn and turns to see a limo pull up. Jazz recalls seeing that limo during her and LJ's date. The driver steps out and tips his hat.

"Ah, Ms. Fenton. Lovely to see you again." He said.

"Wait? Charlie?" Jazz asked.

"Who?" Danny asked.

"He was one of the waiters at the Golden Cafe." Jazz said.

"THE GOLDEN CAFE?!" Dash and Paulina shouted.

"Yes, I also drive the limo. Mr. Devilman was very generous to give me two jobs. They're around the same pay, and I don't have to do both of them at the same time. In fact, I'm here to take you and your brother to his house." Charlie said.

"Really? Thanks." Jazz smiles.

"Sound like LJ still trying to impress you," Danny smirks.

"Shut up and get in." Jazz said.

Danny just laughs as they both climb it. Danny turns to see Dash and Paulina standing there, still shocked.

"What about them?" Charlie asked.

"Oh, they're nobodies," Danny said.

"NOBODIES!" Dash shouted.

"Charlie, you can take us to LJ's place now." Jazz said.

"Very good, Ms. Fenton." He said and got in the driver's side.

"Later, losers!" Danny calls out as they drive away.

Lucy was finishing her last plate for their double date and sighs. LJ walks in and notices her look.

"Lucy, it's going to be okay," LJ said.

"I'm still scared. I was able to hold Danny off, but this is it. We have to tell them this time." She said.

"I know. I'm nervous too. Listen, Lucy, no matter what happens, let's cherish this happy moment. I'm here for you." He said.

"I know," Lucy said before a knock was heard.

"Ah, they're here," LJ said and walk to the door.

He opens it and saw both Danny and Jazz.

"Danny, Jazz! Welcome! Please come in." He said.

"Hi, LJ." Jazz said and hugs him.

"Hey, Lucy!" Danny said to her.

"Hi, Danny," Lucy said back, and they share a kiss.

Lucy left to get clean up after that, and soon the four sat at the table, talking and joking around. It was almost enough to make Lucy forget why they were over. However, LJ was the one that brought it back.

"Danny, Jazz? There's another reason we call you over." He said.

"Right, you both wanted to tell us something," Danny said.

"Yeah, you both have been hush, hush, about it." Jazz added.

"Yes, it mostly because we are afraid of how you would react," Lucy said.

"React? React to what?" Danny asked.

"Danny, do you remember last week when I asked you about demon girls?" Lucy asked him.

Danny nods and she sighs. She reaches up and took off her headband, showing her horns. She then unwraps her tail and looks at Danny. Danny was surprised. He got up and felt the horns, he then grabs the tail and gave it a small pull, making Lucy squeaks and blush.

"Um, Danny? Don't pull her tail." LJ said.

"Wait, you knew?" Danny asked.

"Yes," LJ said, unwrapping his tail and made his horns show.

Jazz look shocked before Lucy sighs.

"Me and my brother are demons," Lucy said.

"Demons?!" Jazz shouted.

"We have every intention of telling you both. You're both the first humans to ever like us." LJ said, before sighing.

"And there another secret we need to tell you," Lucy said.

"You heard us talk about our father, but we never mention his name. You heard of him, and he goes by many names. But there is one name I'm sure you heard of many times." LJ said.

"And it on my apron," Lucy said.

"Wait, you two are the children of Satan?!" Jazz yells.

"Only two of them. There are actually 666 of us." LJ said.

"What?" Danny asked.

"I'm sorry, Danny. I didn't want to keep it from you, but this world is different. I wasn't sure if you would like me if you knew." Lucy said.

"And remember. We said that we are not like our father. If you need time to think it over, we understand." LJ said.

"We do," Danny said looking at Jazz.

"Very well. Come see us when you're done." LJ said and leaded Lucy to his living room.

The siblings sat down on the couch, and Lucy looks upset. LJ places a hand on her shoulder and sighs.

"We had to tell them. It's only a matter of time before they learn about it another way." LJ said.

"I know, but I really like Danny. I really do." She said.

"And I like Jazz. Lucy, it's up to them now." LJ said.

Back in the kitchen, Danny sat down and sighs. He was dating the daughter of the devil. And Jazz was dating his son. It made Danny wonder if he should break it off. Jazz, on the other hand, just sighs.

"Danny?" She said, making him turned.

"I think we shouldn't break it off." She said.

"What? Why?" Danny asked.

"I get their the children of the devil, but I don't think that this whole was a trick. LJ really impress me and it seems he was really want to go into a relationship. During the nights I spend here, LJ never did anything to me or force me into anything. And think about Lucy, did she do anything to you?" Jazz asked.

Danny thought about it and saw Jazz's point. Lucy never forces him into anything either. During all the time they slept in bed together, they would both check to see if their clothes were on. Then he recalls what he said about Demon Girls. Lucy has been nothing but nice to him.

"Well, I did say if a demon girl was nice to me and others, I could see us getting along." He said.

"They kept it from us because they were scared. I understand that. I don't think we should break it off because of that." Jazz said.

"You're right. But I think we better keep this to ourselves. If someone else finds out..." Danny started to say.

"I know." Jazz said and stood up.

"Come on, let's go talk to them." She said.

LJ and Lucy stay on the couch before they spotted the Fentons walk in.

"Well?" LJ asked as Lucy prepares for the worst.

"We talk it over and have decided." Jazz said.

"We're not breaking it off," Danny said.

"You're not?" Lucy asked.

"No, demons or not, you two had shown us that you're different. You might be the children the devil, but you say you're nothing like him." Jazz said.

"Indeed, our father cares nothing for us. We are our own demons." LJ said.

"Okay." Jazz said and saw next to him.

LJ smiles and leans on Jazz. Danny sat down next to Lucy and notices her face.

"Hey, it's okay. I admit this was surprising, but you're still the same girl I know. Jazz reminds me that you never force me into anything and how much you care for me. I feel like an idiot thinking about breaking it off. Plus, you've been nice to me and others. I did say that type of demon girl is someone I can see myself with." Danny told her.

Lucy smiles and looks at Danny.

"Thank you." She said, and kiss him.

Danny kiss back and the two couples just sat there. It was later they continue the date night. This time LJ and Lucy were keeping their horns and tails out. LJ told them that their father had named him the heir to his throne, but he wanted nothing of it. Lucy mentions that ever since she learns to cook, her father always brought her back to have her food, she would never stay after she was done. They had a great time, and Lucy had to return to her apartment. Danny went with her and she was very happy.

"Okay, Lucy. Have a safe trip." LJ said.

"I will." She said.

"Danny, me and my siblings are trusting you to watch over her and make her happy. Just be warned, if you hurt her in any way, we will hunt you down and learn why we are the children of the devil." LJ said.

"Right." Danny gulps.

"That goes for you too Jazz," Lucy added.

"Um, right." Jazz said sheepishly.

With that, Danny and Lucy left. LJ saw down on the couch, and Jazz reaches for his horns. She was surprised on how big they were and how they felt like bone. LJ just sat there, letting Jazz touch them.

"A demon. We're dating demons." Jazz said.

"Do you regret it?" LJ asked.

"I'm not sure." Jazz said before LJ's tail wraps around her.

"Listen, Jazz. No matter what happens, just know that me and Lucy will always love you and your brother. We are glad to meet you." He said.

"I am too." Jazz smiles, letting his tail stay on her.

LJ smiles and they share a kiss. Jazz suddenly broke it when she felt something enter her pants. She turns and saw LJ's tail was sticking in the back of her pants. She turns back to him and saw him smile sheepishly.

"Sorry, sometimes my tail has a mind of it own." He said.

"LJ, do you want to..." Jazz started to ask.

"Honesty? Yes, but I'm trying not too. I love you Jazz, but I don't want to force you into anything you're not ready for." He said.

"Can I tell you something?" She said and got a nod.

"I want to. Yes, I know it only our second date but, I just feel drawn to you. But like you, I don't want to force you." Jazz said before sighing.

"I don't know why." She added.

"Hm, it must be..." LJ said, thinking.

"Must be what?" Jazz asked.

"It's something we demons have. Because of our father, we can bring out the person's desires, and in this case, you want to have sex with me even though we have only been dating for a while." LJ said.

"So, just by being around you, is making me want to have sex?" She said.

"Yes, and trying to stay away won't work," LJ said.

Jazz looks away, but LJ pulls her face back.

"Listen, We both don't what to force it, but if you wish, we can do it." He said.

"LJ..." Jazz sighs and kisses him.

"I forgive you." She said.

Lucy and Danny made it to her apartment as Lucy told Danny the same thing.

"So, you're bring out the desire I want most with you," Danny asked.

"Not that I mean to. We have both been doing a fine job preventing ourselves, but I don't think we could keep it up forever." Lucy said.

"I see, well, my dad did give me and Jazz a talk about the Birds and Bees. Left both of us up for the whole night." Danny said.

Lucy nodded and sat down. Danny sat next to her and sighs.

"Look Lucy, I don't blame you. I'm still trying to get my thoughts together about you being a demon girl, and this is just another surprise. And from what I can tell, you didn't plan this." Danny said.

"I didn't." Lucy agrees.

"Lucy, do you want it?" Danny asked.

"Yes! I wanted it the minute we enter that empty classroom. But I didn't want to be like my siblings." She said.

Danny looks at her and smiles.

"Tell you what, let's do it tonight and see where we going from here." He said.

"Danny?" Lucy asked.

"Something tells me, there will be a day we'll lose control of ourselves. I wanted to wait until you were ready, but if my desire is driving me, then we better do it while we still have control." Danny said.

Lucy smiles and kisses him.

"Okay. For tonight." She said.

And Lucy and LJ had told Danny and Jazz what they are. And they still together. Danny still has his secret, but he'll tell her. Okay, the next chapter is going to be a double lemon. One for Danny and Lucy, and the other for Jazz and LJ. After that, I'm bring Sam and Tucker in. I did a lot for this one, so the lemon is going to happen in the next chapter.
