Warning: This is basically pure smut...with smut as the plot...Also, another female mage will join in this one, so if you're not into that, then don't read. By that I mean, Erza joins in on the smut. So if you just want NaLu, this chapter is not for you. You have been warned.

The guild members who were kicked by Lucy were lying in a heap on the ground while the members who avoided the kick had scattered, subsequently fleeing from the apartment. Natsu was laughing hysterically from the bed at his unconscious guild mates until Lucy turned around. He could feel the dark aura emanating from her as she faced him, but as they made eye contact her expression changed to a big toothy grin.

Natsu and Lucy were able to pull most of the guild members out of her apartment where they rested on the step near her door. Lucy felt bad dropping Erza out there, and Natsu was frightened at the perceived consequences of that action, so they decided to leave her on the floor in Lucy's room.

The couple prepared breakfast, expecting the red haired mage to be awake by the time they finished, but found her in the same position in Lucy's room. They sighed at the situation and looked at each other not knowing what to do. They could leave Erza there and go to the guild, but Lucy didn't want to leave her alone. She was worried that Erza would snoop and go through her underwear again. She also didn't want to leave Natsu with Erza alone because they would definitely snoop together if she did that! Natsu wouldn't want to leave Lucy alone with Erza because he was afraid if he left her today, then Lucy would change her mind about being his mate.

They argued about it a little before sharing annoyance at each other's stubbornness and stalking over to the bed. They sat down in a huff and looked around the room awkwardly. Natsu felt annoyed at the presence of Erza but had an idea. If only Lucy would let him move her to the kitchen….then they would be alone again.

Turning his head to face Lucy, Natsu put his smoldering expression on while gazing into her eyes and said, "let's throw Erza down the stairs." Wink.

"Natsu! We can't do that! Baka! She would get hurt, and imagine how angry she would get if she knew you threw her down the stairs. But nice try," Lucy explained.

Sighing, Natsu stood up and walked towards Erza seeing no other choice. He bent over and put one arm under her knees while draping her other arm over his shoulder. "I'll just gently carry her down the stairs then. And gently place her in the kitchen. And gently leave a sign, which you can write Lucy, saying: leave Erza we are busy."

Lucy felt annoyed but giggled at his sign idea anyways. It would be kind of funny, especially since Erza gets so awkward about sex. Even just the idea of it would make her uncomfortable. Haha. Lucy grabbed a piece of paper from her desk and wrote Natsu's words on it. She brought it downstairs and placed it on top of her. She also added the word sorry to the back because she felt slightly guilty.

Natsu and Lucy snuck back upstairs into Lucy's room and shut the door quietly. In a way, having Erza there made it a little more naughty. They felt like they had to keep quiet about the situation, which caused the giggles to erupt from their mouths.

Lucy laid on the bed as Natsu climbed over her, still giggling. He started at her ankle and kissed his way up her leg stopping at her skirt. (She had changed when her guild mates were unconscious.) Lucy grabbed his hair and pulled him up to her lips.

They kissed passionately, tongues fighting for dominance and lips smacking. She bit his lower lip while growled and swirled his tongue around hers. Natsu broke the kiss to lean into her neck where he started to suck her skin. He let his hand graze down her body towards her breasts and squeezed them roughly, making her moan in the process. He tore her shirt off and burned it in the process, causing Lucy to slap him. She attempted to rip his shirt in return when he pulled away from her and burned it off himself.

The sight of small flames licking Natsu's torso while his shirt crumbles to ashes was beautiful. His pink hair almost glowed at the sight, and when he leaned back towards Lucy she reveled in his warmth. She pulled his chest hair with her left arm while letting her nails dig into his back as she pulled him closer to her.

Natsu smiled at Lucy's roughness and bent down to lick her neck. His urge to mark her was growing stronger with every kiss, but he had to suppress it until they could talk about it. He kissed down her torso while she rubbed her hands along his back. He kisses down to her belly button before pulling her skirt and panties off.

His head dipped between her legs as he heard her gasp from the sudden feeling. His tongue circled the inside of her cunt as he made it wet with saliva. He could taste the beginnings of her juice leak out of her, so he knew it was time to move upwards. Natsu began licking her clit gently while she rocked her hips onto his face and moaning in the process. He started to suck her clit deeply as he plunged a finger into her.

He rubbed her from the inside, hitting just the right spot as her legs shook in ecstasy. Her fingers from her right hand were entwined in his hair, while her left hand was busy groping her breast. Lucy flew her head back and whimpered Natsu, begging for more. He complied by sticking a second finger into her. He scissored them out, stretching her a little and preparing her for his cock. "Do you like this Luce? You want me to fuck you? What do you want most Luce?" Natsu warmed up his fingers as his pants got tighter.

He felt more turned on from the dirty talk and waited for Luce to respond as he sucked her clit. She groaned and whispered, "Enter me as I finish cumming from your mouth. Nnnrg. Ahhh natsu I'm close. Faster please." She was bucking her hips wildly as he circled his tongue around her clit and pushed his fingers inside her harder and faster.

When she just started to cum, Natsu pulled his head away from her pussy, pulled his fingers out, and crawled up her body. She was still grinding her hips in the air as he placed his hardened member by her entrance. He watched her cry out his name from the end of her orgasm as he pushed inside her.

She yelped in pleasure and wrapped her legs around his waste. He started banging her hard, watching her breasts jiggle with the movement of the bed. He let his magic heat her up from the inside. He started by making his tip hot and let the warmth move down to his balls from there. Every time he slammed into her, she could feel the heat of him slap her. He let his balls be the hottest part of him so that she could feel the difference every time he pushed against her.

Lucy couldn't control any of her sounds at this point and was moaning with every thrust. He was getting close to the edge when she threw her arms back and cried out, "NATSUUUU." Her orgasm lasted longer because he was slowly pressing his cock against her internal wall. He felt himself ready to burst as he thrusted into Lucy frantically. As he was cumming he let his dragon fangs turn red from heat and felt them lengthen as he pressed his teeth against her neck. He burned her skin, leaving his mark, as they orgasmed together, the pain making it stronger. As she rode out the wave of pleasure she looked to the door to see Erza's stunned face watching her.

Erza had woken at Lucy's first yelp of pleasure, as a concerned friend she rushed up to her room to see what was happening but eased the door open slowly because of the sounds she was hearing. The panting paired with Natsu grunts and Lucy moans was the strangest sounds Erza had encountered. So she cautiously peeked her head.

She had read plenty of dirty novels that she borrowed from Levy, but this was her first time seeing this type of action. She watched in awe as Natsu devoured Lucy. Erza paid attention to the sweat the dripped down Lucy's breasts and they slightly bounced in the motion. Her eyes wondered down her body and she saw Natsu add another finger into her. Erza had never done anything like that.

She watched in curiosity, knowing it was wrong, but couldn't pull her eyes away. When they started to talk dirty she pressed her thighs together and had trouble not moving her hips. Erza was aware of being turned on, due to reading, but this was the strongest she had ever felt this urge for pleasure.

As Erza watched Natsu finger Lucy, she unconsciously started gliding her hand down under her skirt. When natsu switched from sucking Lucy's clit to circling it, Erze dipped her hand under her panties allowed her finger to copy Natsu's tongue. She opened her thighs a little as she watched Lucy do the same.

Natsu slid his fingers against Lucy harder and faster, and Erza wanted to keep the pace so she circled her clit faster while bucking her hips. At this point Erza had realized that she was fingering herself, but didn't care any longer. It felt too good. As Lucy came onto Natsu's mouth, Erza had to suppress a moan from her mouth.

She watched as Natsu crawled up Lucy's body, eyes wide at the length of his cock, and felt a warmth spread inside her as he watched him enter her. She let a finger slide inside her as she thrusted it in and out. She copied their movements with her finger and bit her lip to keep from letting a sound out. When Natsu ground against Lucy in frantic movements, Erza knew it was coming to an end. She knew that she should leave but then she saw his teeth turn red and was mesmerized by the sight.

Erza stared shocked at the mark on Lucy's neck, and didn't even realize that they had spotted her. Lucy froze in embarrassment, while natsu scratched the back of his head. He pulled out of Lucy, but caught a pleasant smell coming from Erza.

He could smell that she was very turned on, and he knew it was because she watched. Natsu stood from the bed, in all his nude glory, and sauntered over to Erza. He pulled the door open and looked down at her. His body was covering Erza enough so that Lucy could not see Erza. But Natsu watch Erza turn red as she pulled her finger out from her panties.

Natsu, after thinking about it and deciding that Lucy seemed pretty adventurous, decided to try something out. He lifted Erza's wet finger to his mouth and gently sucked it. She tasted different than Lucy, less sweet and a little sour, but still good. He smirked at her as he watched her eyes widen. He took her hand into his and walked her over to the bed.

He asked Lucy if Erza could join them, while Erza stood by the bed nervously shaking. Lucy watched Erza for a minute, pursing her lips. She wasn't sure if she would like kissing Erza, but it was worth a try. Lucy shyly nodded and looked over to a giddy Natsu.

Natsu was the first to kiss Erza. He pulled her in for a kiss while her hands lay at her sides. She felt like she was on a stage and couldn't move from the fright of the audience. She let her lips dance against Natsu's as she closed her eyes and reminded herself that she was not on a stage.

Once Erza felt back to her old self, she equipped out of her armor and stood before Lucy and Natsu in the nude. She smiled at them with a glint in her eyes as she hopped onto the bed to straddle Lucy. Erza bent over Lucy to kiss her, with her ass in the air. Lucy let her legs straddle Erza's hips as they began grinding against each other.

Natsu stared at the ladies, so turned on by the sight of their breasts rubbing against each other. He was behind them in no time. His mouth was on Erza's pussy while he had a finger in Lucy and a finger from his other hand in Erza. Natsu smiled as he enjoyed the cunts in front of him.

Lucy was getting more comfortable with Erza on top, so she pressed her tongue against Erza's lips. When Natsu thrust his finger inside Erza, she moaned and Lucy pushed her tongue inside Erza's mouth. Erza was hesitant at first, but quickly found her strength in the kiss as they made out. Both girls began fondling the other's breasts, curiosity getting the best of them. They were both grinding each other as Natsu finger fucked them.

Natsu spoke to Erza while he thrust a second finger inside her, his tongue was licking between both girls clits since the protruding clits were practically touching each other, "Erza, do you want my cock today?"

He could hear Erza moan and Lucy pant from his actions, and felt his cock hit his stomach. He was aching to push inside Erza. She loudly yelled, "Yess, Natsuu, take me like you took Lucy."

Natsu pulled his fingers from the girls as he grabbed their hips and placed his cock outside Erza's entrance. He pushed inside her slowly. When she started to move back against him, he let himself thrust all the way in her. She cried out in pleasure as Lucy felt his balls hit her outer lips.

Lucy and Erza were frantically grabbing each others bodies as they kissed. The friction from grinding against Erza was enough for Lucy to be close to orgasming. But when she felt Erza buck against her rapidly and hard she knew that Erza was about to experience her first Natsu induced cum. The thought alone drives her over the edge.

As Natsu pushed deep inside Erza, he watched Lucy cum and fucked Erza hard to get her over the edge. He hit her G-spot repeatedly until she started clenching around his cock. It felt so good that he let his seed out inside her. He growled his release and listened to her scream. Erza could be very loud.

Natsu and Erza collapsed on top of Lucy as they calmed down from their climax. Lucy poked and prodded at them until Natsu pulled out of Erza and slid to the side of Lucy, which enabled Erza to lay over both of them.

The three of them lay there panting as reality set in. Erza just had sex with Natsu and Lucy, and she had no idea how this would affect their friendship. She looked over at her dear Nakama, and smiled at them. She knew that despite this fun encounter, they would be continue their friendship. It may be awkward in the weeks to come, and she really hopes that no one in the guild finds out, but they will all move on from it.

Erza stood up from the bed and bowed to the couple. She thanked them for allowing her to join them as she reequipped into her armor, purposefully leaving her panties off. Erza quickly said goodbye before fleeing the scene.

Lucy and Natsu just stared at each other before laughing awkwardly. They never expected to do that with Erza, but it wasn't bad. Maybe they would invite her to join them again.
