Danny and Lucy enter her room, and Lucy had him sit on the bed. She smiles and took off her shirt. She then kisses him as she rubs her hand on the "spot". She kept it up until there was a lump form. She broke the kiss, and unzip his pants and pull out his cock. She was surprised at how big it was and smiles. She grabs it with her hand and started to jerk it slowly. Danny just sat still as she did. Lucy then stops and got on her knees, before taking her bra off. Danny was surprised that her breasts were a bit bigger, and she places them on his cock. She started to move her breasts around, and Danny could only moan from the feeling. She then stops and started to lick the tip. Danny kept flinching from it as she kept licking. She then started to place his cock in her mouth and suck at it a bit.

"Lucy!" Danny moans as she kept sucking.

Lucy just kept it up, and close her eyes. Finally, Danny couldn't hold himself back. He grabs the back of her head and stuffs it down her throat, making her gag a bit. He started thrusting into her mouth, and Lucy just took it. Being a Demon means she could handle the pain that she was getting. She knew Danny wasn't trying to hurt her, but it clear he couldn't hold back. He then stood up, bringing her along, and freeing the rest of his cock from her breasts. He then pull her so far down, she had the whole cock in her mouth. It was enough for Lucy's eyes to roll to the back of her head as Danny thrust as hard as he could.

"Cum...Cuming!" He said and shot into her mouth.

Lucy could barely shallow what Danny fire in her mouth, some of his cum even leak out. Danny panted and sat down. Lucy pulls away and shallows what she had. Danny looks down at her and saw the Lucy was looking back at him with a cute face and some cum on her breasts.

"Lucy..." He started to say, but she stood up.

"Main event." She said and took off her pants.

Danny nods and took off his shirt and pants. Lucy then took off her panties and sat on top of him. She pushes Danny head towards her breast and he started to suck on the nipple. Lucy just moans before her tail wrap around his cock and, the tip started to poke the opening. Danny kept sucking before pulling it and letting go. He looks at her and then pushes her on the bed, her tails still wrap around his cock. He started to suck on the other breast and move his hand towards her pussy and put two fingers in it.

"AH!" Lucy cries out.

Danny started to move his fingers in and out, making her wet. Lucy's tail didn't stop teasing the tip of his cock as Danny didn't let up. Lucy moans as she felt Danny play with her private areas and could feel that she was about to cum. Danny then started to push his fingers deeper make her cry out again. He started to move his fingers around her pussy, making her cry out more.

"Danny! Stop, I'm going to..." She tries to say before Danny pulls his fingers out.

"Your tail is playing with my penis. But, I think I know how to stop it." Danny said, sitting up.

He spreads her legs, and Lucy felt her tail guide his cock to her pussy. Danny pushes the tip in and felt her tail unwrap. He then pushes in more and Lucy could only shut her eyes, as she felt his cock stretch her insides. Soon, Danny reaches a wall and looks at her. Lucy peeks and nods, face red from trying to keep herself from shouting. Danny nods back and pushes as hard as he could. He felt something wet pop and Lucy couldn't hold back a scream.

Danny's cock was inside Lucy's pussy and there was a bit of blood. The two just remain like that for a few seconds, before Danny slowly move in and out. Lucy could only moan again as she felt Danny cock moving her insides with it. Danny kept thrusting before he leads down and kiss her. Lucy returns the kiss and Danny started to move faster. Lucy then breaks the kiss as she moans from the feeling.

"Oh! That's good! Yes, keep going that." She said.

Danny kept going and Lucy lay still. Danny then sat up and place her legs on his shoulders.

"Ready?" He asked.

"Yes, give me all you got." She said.

Danny nodded and push very hard into her. Lucy cried out in pleasure before Danny started to thrust as hard and as fast as he could.

"Oh yes! That's! Feels! Ooff! So! Ah! Wonder! Oh! Ful! AH!" Lucy moans.

Danny kept thrusting as Lucy moans, her breasts bounce from the movement. Danny was really into it. He couldn't believe how amazing she was. And this was their first time. Danny kept it up, thrust as fast and deep as he can, making slapping noises due to how wet Lucy was getting. Danny then stops, making Lucy look at him, trying to catch her breath.

"Why did you stop?" She asked tiredly.

"Just need a minute to catch my breath," Danny said.

Lucy smile and soon flips over until she was on top.

"Rest, let me take over." She said and started to ride his cock.

This time Danny started to moan as Lucy just move up and down. She had her hands placed on his hips as move. Her tail made a heart shape as she started to moan as well.

"Lucy," He said stopping her.

Lucy looks down before Danny sat up.

"Let give it the big finish." He said.

"Yes, I'm ready." She said.

"Good. Hands and knees please," Danny said.

Lucy pull herself out and got on them. Danny places his cock back in her pussy, and started to thrust again. Lucy started to moan as she felt Danny hit her insides even more.

"Faster, Harder!" She said, and he did just that.

Lucy let out some loud moans as Danny kept moving. He then started to move even faster and deeper. Lucy moans become louder and looks back at Danny.

"Danny, don't hold back. Fuck me like crazy, make me your bitch." She said.

Danny did just that. She was pounding so hard that Lucy was letting out loud cries for pleasure. Danny didn't stop, Lucy's breasts were flying about and her tail was moving around before it wraps around his waist.

"OH YES! THAT'S IT! FUCK ME! FUCK ME!" Lucy shouted.

Danny then leads down on her back and kept thrusting. Lucy could only cry out louder.

"FUCK! OH FUCK! THAT'S...FUCK!" She screams.

"Lucy, I'm going to cum!" Danny said.

"OH YES! JUST DO IT! CUM INSIDE! FUCK! FUCK!" She shouted.

Danny kept going until he felt something warm build up in his cock. With one last thrust, he shot his cum deep inside her.

"OH FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUCK!" Lucy shouted as Danny shot wave after wave inside her.

The two then fell on the bed, with Danny laying on top of her, both of them trying to catch their breath.

"Fuck, that was so amazing. I can still feel you coming." Lucy said.

"Augh, you were so tight. I felt that I was going to pop." Danny said.

"Can you move?" Lucy asked, only to felt Danny thrust again.

"Does that answer your question?" He said.

Lucy just smiles as Danny kept thrusting. Lucy moans as she felt Danny trying to push his cum inside her even more. Danny felt her strength return, thanks to his ghost powers, and sat up, grabbing Lucy by the side and brought her up with him, until he was sitting up and Lucy was on his lap.

"Danny, how did you recover so fast?" Lucy asked.

"Humans can have a lot of energy." He said and started to thrust her again.

Lucy moans as she felt herself move up and down at each thrust. She just sat before feeling Danny reach up, and grabs her breasts, and started to play with them. She moans even more as Danny didn't stop. He could already feel himself coming inside her, without warning but Lucy didn't mind. Once he was done, Lucy unwraps her tail and spins around. She wraps herself around him and started to ride him. Danny quickly took over and was thrust her hard once again.

"Oh! Oh! Yes! That's it! Keep hitting there!" She moans.

Danny did and soon he cums again. Lucy then pulls him down and smiles.

"Don't quit now. I got room in the tank." She said.

Danny nodded and thrust again. As he did, Lucy's horns started to glow and grew longer. Neither of them notices as Danny could feel himself cum once again.

"Darn, I keep coming too soon." He said.

"You did shoot a lot into me the first time," Lucy remind him.

"I'm surprised I still have a lot in me," Danny said.

"Which is fine. More for you to put inside." Lucy said.

Danny nodded and started to thrust again. Lucy just moans as Danny fucks her through the rest of the night.

Jazz and LJ were laying on his bed in their underwear. They share a kiss before LJ look at her.

"Jazz, as you know, I have done this with many girls. Meaning that I have lots of practice. So I know how to make you feel good with this." He said.

"I understand. Those girls aren't going to come back to seek you, are they?" Jazz asked.

"No, they won't be able to find me, but I'll make sure you can," LJ said.

Jazz smiles and kisses him again. LJ then moves his tail towards Jazz's bra and wraps it around. With a soft pull, the bra comes off, showing her breasts. LJ grabs them and slowly moves them around. Jazz just moans from the feeling. LJ moves them around for a few minutes before his tail went into her panties and started to rub her pussy. Jazz gasps from it.

"There is one thing, no of the girls has sex with me like this. You're the first." He said.

"LJ..." Jazz said before remaining still.

LJ continues to moves Jazz's breasts, and his tail kept rubbing her pussy. He stops and pulls his tail away. Jazz look at him, wondering what he was doing.

"Jazz, before we continue, I need to make sure of something." He said.

"What?" Jazz asked.

"As a Demon I can make you feel so good, that you don't want me to stop. However, I do not want to force you to give up anything. Because I like you, once we go past this point, you will be forever marked as my mate. Lucy is still young and doesn't know that she and Danny are mates now." LJ said.

"So, that means..." Jazz started to asked.

"Yes, you will make a deal with the son of the devil. Do you really want it?" LJ asked.

Jazz had to think about it. Once she and LJ do the main phase, she would be marked as his mate. He has done with many girls, but she was the first girl he ever likes. Could she really give herself up to a demon?

"LJ, I love you. I will admit finding out you're a demon and the son of the devil is surprising news. And I know you don't want to force me into anything. I guess I'm okay with this." Jazz said.

"Jazz, you need to be really sure. Are you going to give yourself freely to a demon?" LJ asked.

Jazz sighs and nods. LJ sighs and knew what to do, he removes his boxers and pulls off her panties. Jazz gasps at the size. LJ then moves his cock to her pussy and pushes the tip in.

"With the connect untied, let this human be marked as a demon lover." He said and push it in.

Jazz cry out in a bit of pain as she felt LJ's cock stretch her inside. Soon he was fully in, and Jazz looks at him.

"Your mine now, Jazz." He said, his eye glowing a bit.

Jazz was about to ask what next, but LJ just started thrusting as hard as he could. Jazz was caught by surprise and screams, as LJ continues thrusting. LJ didn't let up, and Jazz couldn't stop her screaming. Finally, LJ cums inside her making Jazz numb from the feeling. She lay on the bed as LJ fills her with his cum. He pants and sat up.

"I'm sorry, being the oldest son means I have a higher chance of letting my "beast" side out." He said.

Jazz couldn't say anything and LJ knew why.

"You're lucky that I didn't do too far. Jazz, you let yourself get taken by a demon. That not a good thing, but that doesn't mean you lost your humanity." He said and leads down.

"Jazz, you're my mate now. Do you wish to continue?" He said, then asked.

Jazz could only nod softly. LJ nods back and started to thrust again, this time slowly. Jazz just moans as LJ moves. Then LJ's tail reaches over and wraps itself around her breasts and started to squeeze them. LJ kept thrust in Jazz before he cums again. Jazz just twitch as the tail kept squeezing her breasts. LJ pulls himself out and unwraps his tail. He climbs up and places his cock at her mouth. Jazz opens her mouth, and LJ sticks him cock inside. Jazz moans as LJ thrust in her mouth. LJ could tell that each time he does this, Jazz was losing more and more of her strength. He also knew that he could actually turn her into a demon, but he didn't want to. He sighs and hopes Lucy didn't do the same with Danny.

He looks down and then cums in her mouth. He pulls free, and Jazz shallows his cum. He then leads down and had his horns touch Jazz's forehead. They glow and Jazz suddenly felt some of her strength return to her and looks at him.

"LJ?" She said.

"I gave you some of my energy. I know you want to be able to move." He said.

"I didn't think you're would be like that," Jazz said, getting her breath back.

"It because I'm the son of the devil. But don't worry, it won't happen again." LJ said.

Jazz nods and LJ continues to thrust in her. Jazz just lets him as they had sex through the night.

And that the Double Lemon. Danny's and Lucy's were simple and acted like a normal couple. Jazz's and LJ's were rougher because LJ knew what would happen if Jazz agrees to let herself be taken by a demon. And if you wondering why Danny didn't tell Lucy about his ghost powers, he just found out that she was a demon and didn't think about his secret. He will tell her, but later. Well, next chapter, Tucker and Sam come back to Amity Park and meets Lucy. And if you know your Danny Phantom Lore, Sam is going to be surprised to find that Lucy is Danny's girlfriend and learns that she a demon.
