Both Danny and Giga had to sneak back into the hotel. The two just couldn't stop mating. It was their first time and it turn out they were the first of their kind to mate within 1,000 years. Giga made it to the shared room, wearing her human clothes. She opens the door and spotted Jazz sleeping and Sam tied up. She quietly walks in and shuts the door. Seeing that no one was going to wake up, she started to undress, heading for the shower. She knew the seawater would cause questions she didn't want to answer. As she wash her human body off, she thought back to her's and Danny's mating. Who knew mating with a human was so good? She now understood what Danny meant that humans sometimes can't help themselves during it. She could still feel his rod in her and moans.
'Easy there, Giga! He's too young. As awesome as it was, I need to make sure that we don't get carried away.' She thought sighing.
"Giga? Are you there?"
She heard Jazz through the door, she must have woken up.
"Yeah! I'm taking a shower." Giga said.
"I thought mermaids don't shower?" Jazz asked.
"Human skin." Giga reminds her.
"Right. What the?! Sam stop!" Jazz shouted.
Giga blinks before the shower curtain was yanked away, and Sam jumped on her, pinning her to the wall.
"YOU LITTLE BITCH! HOW DARE YOU!" She shouted.
Giga sighs. It seems that Sam couldn't hold back anymore and tried to attack her. She might not be able to turn into her full size, but that doesn't mean she couldn't use her powers. Using her hand, she made a ball of water appear over Sam's head before dropping it, causing the goth to back off, soaked. Giga pushes her out of the shower and steps out, turning her skin back to normal.
"Jealously, I know that look anywhere. Don't deny it! I've seen that look on many of my people!" She said, angrily.
"You're trying to fight me because I won my mate's heart when you did nothing! Had my people been here and seen you attacked me, they would arrest you and declare an punishment for you. You're might be Danny's friend, but I will NOT TOLERATE WITH YOUR WAYS TOWARDS ME!" She screams.
"Danny was mine! You're nothing more than an overgrown fish that knows nothing about love!" Sam shouted.
"Nothing about?!" Giga asked, growling.
Giga slaps her, knocking her toward the floor before standing over her.
"Just because I'm not human, doesn't mean I don't know what love is! Danny saved my life ten years ago, and I barely knew him! I didn't come forward for those ten years because I was scared! I never stop growing! I was scared that he wouldn't see me as the mermaid he saved. I was afraid that I could hurt him when I get close! But it turns out all that fear was for nothing! He remembered me! I was more careful than I thought! After figuring out how to make myself smaller, I got to know him in ways I never thought! What? You thought after he left at the end of the summer, he was going to forget me?! You thought you were going to have him to yourself?!" She told her.
Sam looked ready to jump on Giga before Jazz grabs her.
"Let me go!" Sam yelled.
"No, Sam! You need to stop!" Jazz said, holding the goth back.
"She not the one for him! She needs to go!" Sam said.
"No, Sam! You need to go. Danny invited you to come along because you're his friend! If you keep this up, you'll destroy the friendship you have with him." Jazz told her.
Giga had spent time drying herself off and wrapping a towel around her body. She even turns her skin back into her human skin.
"This will not be forgiven, Sam. If you can't accept that Danny loves me and I love him, then you have no right to call yourself his friend." Giga said, walking past the girls.
"What in the name of spooks is going on?!"
Everyone turns and saw Jack barge into the room.
"DAD!" Jazz shouted, glad that they were still dressed, mostly.
"Mr. Fenton, it rude to come rushing in the room without knocking," Giga said, holding her towel close.
"Um, right, sorry," Jack said, sheepishly.
"What all the yelling?" Maddie asked.
"Sam attacked me when I was taking a shower. She doesn't approve of me and your son dating." Giga said.
Jack and Maddie were surprised at that.
"You did more than that! You didn't come back until dawn!" Sam shouted.
"We were talking and feel sleep outside. When we awoke, it was almost dawn. We had to rush back here before we got in trouble." Giga said, not telling everyone the real reason.
Sam didn't believe her and tried to break free, but Jazz kept her grip on her. Jack and Maddie looked confused but sighed.
"Alright. We might not like that Danny sneak out, but we're very disappointed in you, Sam." Maddie said.
"Yeah, Gine treated him really well, and Danny likes her!" Jack said.
"As much as your parents don't like us, we're going to call them and inform your actions," Maddie added.
"NO! You can't!" Sma shouted, worried.
Maddie sighs before turning to Giga.
"Gine, I know you're not a bad girl, so I'll let you off with a warning this time. But if you did it again, we'll call your parents as well." She added.
"You have my word, Mrs. Fenton." Giga bows, still holding her towel.
Later,
Everyone meet up at the beach and Giga told Danny what happen with her and Sam. Danny groans and facepalms himself.
"Great. Just great." He groans.
"I'm sorry if I cause you any trouble. Sam was being impossible this morning." Giga said.
"I'm more shocked she attacked you and called you an overgrown fish," Danny said.
"I've been called worst." Giga shrugs.
"I just that's it then," Danny said, knowing that Sam's parents were on their way to pick her up.
"Again, I'm sorry for causing any trouble," Giga told him.
"Sam brought on to herself. I thought she had better control than that." Danny sighs.
Giga sighs as they walked down the beach, making it impossible for Sam to spy on them. However, Danny could not stop thinking about last night. What Sma did was upsetting, but he could shake the night from his head.
"Damn it." He whispers, groaning.
"What wrong?" Giga asked.
"Remember when I said that sometimes teens can't help themselves with having sex? I'm kind of following under the category now. I can't stop thinking about last night." Danny said.
Giga looks away and sighs.
"Me too, actually." She said.
"So, you want to do it again?" Danny asked, facepalming after he said that.
"Sorry! I didn't mean to say that." He said, cursing his Fenton Luck.
Giga couldn't blame him. After Sam's little episode, her mind kept drawing back to last night. Usually, mermaids mated longer than one night. She didn't want to get Danny into trouble, so she fought the feeling and had them get back to the hotel. She could feel her legs rub against each other, a tell-tale sign that she wasn't satisfied from last night.
"Might as well. If I was my real self, my tail would be forcing me close to you." She said, sighing.
"Well, I did spot a cave we could use. It's not like the one we use last night, but," Danny said.
"It's fine. Let's hurry before I decide to strip right here." Giga told him.
Danny nodded and quickly lean Giga to the cave, trying not to be extra about having sex again.
Meanwhile,
Sam pouted as she saw the limo of her parents pull up and argued with Fentons. However, she notices that Danny and Giga were missing.
"Don't even try it, Sam!" Jazz said.
"And you're not worry where they're at?" Sam asked.
"No, because I understand they love each other! Sam, you need to let go. You lost Danny and you need to stop trying to steal him away from others that like him." Jazz said.
Sam groans, crossing his arms.
"I'm with Jazz on this," Tucker spoke up.
"WHAT?!" Sam asked, shocked.
"So what if Danny's dating a..."
Tucker stopped to make sure they were alone.
"...a mermaid? From what I saw, they really do love each other. If Danny's happy with someone that's not even human, then that's his choice." He said.
Sam looked ready to beat Tucker up for that, but Jazz stopped her.
"Don't. You're already in enough trouble." She said.
Sam groans, listening to her family argue with Danny's family.
With Danny and Giga,
After finding the cave, Giga and Danny when to work. Giga was in her normal mermaid form, with her legs, as Danny pounds her from behind. Both of them couldn't help it. No matter what they tried, last night was stuck in their minds. They hope it would settle down after one round, but they couldn't stop. Danny came again before he and Giga fell to the floor.
"Damn it. I can't pull out." Danny said, unable to stop thrusting.
"Ohhh! I can't pull away either!" Giga moans.
Danny came a few minutes later, finally stopping.
"Damn it. We must want it bad." Danny said, playing with Giga's breasts.
"Normally, when mermaids mate, we mate for days. It's the same for Queens. Damn, I don't want us to spit up yet." Giga explains.
"What do we do? My parents will come looking for us." Danny asked, pinching her nipples.
"Augh! I don't know. We can only stay away from each other for a few minutes. It's part of my nature as a mermaid. It happens so we could rest up and eat before we go back to it. Even if you finally gain control of yourself, I won't be able to stop." Giga told him.
Danny sighs. He wasn't sure if they could keep doing this until Giga was satisfied. He trusted her, but he didn't want to force into having sex with her when he was done. There had to be a way to stop themselves from doing this for hours.
"Oh! Danny! You came again." Giga moans, feeling his hot cum fill her pussy.
She was lucky that mating season didn't lean into impregnation. She knew they were too young to have a child. Plus, no one knew what a child and mermaid could be since they are the first to mate in 1,000 of years.
Danny was able to fight the feeling and pulled himself away from Giga. He panted as he sat down.
"Fuck! I need to rest!" He said as Giga push herself up.
"The rest. I'm not done." She said, sitting on his lap.
She put the rod back in and put her arms around his head. She started riding it, unable to stop herself.
'Damn it! I can't stop!' She thought, biting her button lip, trying to make him cum again.
However, something was thrown into the cave and a pink power appear, covering them both.
"What is that?" Danny coughs.
Giga could feel her sense clear up and smell the power.
"Sweet Coral!" She said, surprised.
"My queen? Is that really you?"
Giga turns and saw her people at the cave entrances, shocked to see her so small and mating with a human. Acting quickly, she threw up a water wall and put on her seashells. She then helped Danny get dressed, knowing that sweet coral will free their minds for a few hours.
After they were done, Giga dropped the water wall.
"Claria, what are you doing here?" Giga asked, standing up.
"My queen, You have legs?!" A mermaid shouted.
"Yes, but please answer my question," Giga told them.
"My queen, we have been searching for months! We thought we could find you because you're so big! How did you get so small?" The Old Mermaid asked.
"Well, this jewel helped with that. I can change my size at will and even make myself appear human." Giga said, turning her skin into her human color.
Danny stay back, hoping that they wouldn't try to hurt him for mating with their queen. However, he was surprised when a few mermaids appear next to him, with puddles of water beneath them.
"Are you the human that saved our queen?" One asked, looking over him.
"Um, yes?" Danny said, insured.
"Wow! For a human, he's cute!" Another mermaid giggled.
"Well, he belongs to the queen. We did catch them in the middle of mating." The first said.
"Everyone, please give Danny some room," Giga said, walking up to them.
Danny watched as the mermaids suddenly drive into the puddles, disappearing. Giga helped him up and turns to her caretaker.
"It answers your question, Claria, after I told you that I love Danny, I wanted to be alone. The next thing I know, I was being called. I then meet the Siren Queen, who helped me get closer to Danny..." Giga explains.
"YOU MET THE SIREN QUEEN?!" The mermaids shouted in shock.
"Yes, it's because of her I can be with Danny," Giga said.
"Though, I didn't expect for you two to go that far."
Everyone turns as they saw the Siren Queen stepping out of the water, smirking evilly.
"Giga, well done. I'm happy you got your love. While I wasn't excepting for you to mate, my plan worked perfectly." She said.
"Plan?" Danny asked.
"What are you talking about?" Giga asked, confused.
"Oh, my sweet, naive, Giga mermaid. You had no clue that you were being used." The Siren Queen said before she held up a hand.
An energy ball appear and she threw it at Giga, shocking her and knocking her down.
"Giga!" Danny shouted, rushing towards her.
He suddenly froze before he was pulled away from Giga and into the waiting arms of the Siren Queen.
"Oh, you look much cuter in person. I could tell you were having fun with the queen. How about you show this queen that fun?" She smirks.
"Let me go!" Danny said, trying to break free.
Giga stood up and saw Danny in the Siren Queen's arms. Growling, she stood up and summon water to attack her.
The Siren Queen notices and smirks. She start to glow as the water did nothing to her.
"What?" Giga asked, surprised.
"I must thank you, foolish queen. You wore the sapphire for so long, I have gained most of your power! Soon, I will be the Queen of the Seven Seas, and no one will get in my way! And this human will be my king!" The Siren Queen laughs.
Giga's eyes widen when she heard that. She was tricked?! And her powers were being stolen under her fins?! Giga's eyes turn red as she grabs the jewel and rips it off her head. She roars and started to charge at the Siren Queen, growing big as her legs started to reform into a tail. She jumps towards her, still growing and tackling Siren Queen out of the cave.
And done. What? Did you think that the fight between Giga and the Siren Queen was going to happen now? Nope! I'm saving it for the last chapter.
Well, Sam lost it and is now in trouble. Danny and Giga couldn't help themselves ended up having sex again. But the mermaids appeared, and the Siren Queen had gained enough power from Giga, that she no longer needs to watch from the shadows. So, what will happen next? You'll in the next chapter. Oh, and for those that don't know, I'm already working on my other Monster Girl story. If you haven't read it yet, it's called Harp, the Ghost Harpy. Be warned, it will have rape in it.
