Late at night, sitting alone in his apartment, a 21 year old Lincoln Loud was tapping his pencil on his chin. In front of him was a collection of sketches for the famous comic book super hero, Ace Savvy. Due to his drawing skills, Lincoln had gotten a job working for the company responsible for his favorite hero. Currently tasked with having to create a new sidekick to the hero, Lincoln was completely stumped on what to do.

Letting out a sigh, Lincoln pushed himself back. Standing up and giving a stretch, Lincoln figured a snack can help him get his mind straight. He wasn't tired, not yet at least. As he walked into his kitchen and began snacking on some leftover pizza, he felt his phone vibrate and let out a ding. The white haired man raised an eyebrow as he pulled his phone out, looking down to see who sent him a message. To his surprise, it was from his punk rock sister Luna Loud. Fond memories came across his head, remembering he and his family going to Luna's first big concert. The cheers and jovial screams of her fans was a sound to hear. But what was she texting him for?

"Hey Lincoln...I need someone to talk to. Can I come over?" The text read out. Immediately sensing something was wrong, Lincoln typed back almost instantly. "Sure, you can come by. What's wrong?" He texted. A moment would pass and his phone would ding. "I...I'll just tell you when I get there." Lincoln frowned a bit before texting back "okay" before setting his phone down. It wouldn't be long before he heard his door knock. Going over, he opened the door and widened his eyes in shock at the sight of his sister.

Luna, usually an upbeat and eager going woman, was staring into his eyes with red puffy eyes and ruined makeup. She looked like a total wreck, her hair frazzled and her entire demeanor looking so...vulnerable. They stared at each other for a mere moment before Luna threw her arms around Lincoln and began to let out heavy sobs. The white haired man gulped as he wrapped his arms around his 25 year old sister, gently rubbing her back as she let out hot tears into his chest. He guided her to the couch, setting her down and holding here there.

What felt like an eternity had passed when Luna removed her head from his chest, sniffling and giving a stuttered inhale. "Lincoln...I-I'm sorry..." She stuttered as she rubbed some tears away. "No no, it's fine really. What's wrong?" He asked. Luna looked down, almost afraid to answer. "Luna..." Lincoln held her cheeks up with his hands. "You remember Sam right?" Luna finally told him. Seeing her brother nod, Luna bit her lip before telling him the truth. "When I came home...I found her...in bed with another woman..." she felt fresh tears fall down her already drenched face. "What..." Lincoln widened his eyes.

"I found her in bed with another woman. I was...so angry!" Luna gripped her hands on his legs for only a split moment. "She...she said it was my fault...my fault I was too afraid to marry her..." Luna's breath hitched as she looked down in sorrow. Staring at his sister in silence, Lincoln soon wrapped his arms around her waist and held her close to him. Giving soft, soothing rubs on her back, Lincoln spoke in soft whispers. "You're too good for her anyway. Sam is a damn fool for thinking like that." Luna pulled back a bit. "But Linc-" "But nothing! Listen Luna, you are an amazing woman, an incredible rockstar, and a wonderful sister!" His hands gripped her shoulders gently. "Listen to me when I say this, you are a wonderful person, someone who I would never even think of double crossing! Sure, we had some problems back when we were all kids, but that's all changed! Luna. I love you, you are too incredible to even put into words..." Lincoln softly smiled at her and gave a soft kiss on her forehead.

The entire world froze for Luna. Staring into her younger brothers eyes, she didn't see that goofy kid with the "almost" always good plans. She saw a man she could come to, someone who would hold her whenever she needed it. More tears leaked out of her eyes and fell to her knees, but she smiled as she looked down slowly. "Thank you Lincoln...I love you too bro..." She said before slowly nuzzling into his chest. Lincoln wrapped his hands around her again, holding her close to him as he placed his head on top of hers. "Is...is it alright if I stay the night?" Luna asked. Lincoln smiled softly and nodded, rocking her body gently in his grip.

Their embrace ended a while later. After letting her take a shower, he pulled out a blanket and pillow for the couch. For him of course, he wasn't going to let Luna sleep on his stiff couch. "What are you doing bro?" Luna asked from behind. Lincoln turned but a red blush adorned his cheeks. Wearing only a pair of purple panties, and wearing one of his Ace Savvy shirts, Luna leaned on the doorway frame. Coughing a bit, Lincoln replied, "S-setting up my bed for tonight. You can take my room if you w-want." He smiled up at her. Luna, however, frowned softly. "I was...thinking we could sleep together." She told him.

Oh.

"A-ah...I mean, i-if you want t-too." Lincoln rubbed the back of his head as he rubbed his neck. Luna smiled and walked over to his room, setting herself under the covers and eagerly awaiting his return. Not wanting to keep her waiting, Lincoln quickly prepared himself for bed. Brushing his teeth, washing his face, and getting into some sleepwear, he made his way into his room and pulled the covers over him. He froze when he felt Luna lean into his body, resting her head on his shoulder. Lincoln blushed madly when he felt her developed chest rest on his side. To make matters worse, her hand reached over and grabbed onto his, interlocking her fingers around his in a loving hand hold. "Don't you dare, don't you fucking dare." He cursed at his mind as he tried to focus on sleeping. Luckily, the work from earlier had tired him out, his mind soon escaping into the dark realm of sleep.

Sleep wouldn't seem to last that long as Lincoln felt a weight on his chest. Slowly opening his eyes, he saw that Luna had moved her entire body on top of his. However he didn't hear any soft breaths or light snoring from her. "L-Luna?" Lincoln whispered. His sister turned her head and looked up at him. He saw something in her eyes he's never seen before...

Love...and lust~

"Bro..." Luna moved her body up, placing her hands on his chest as she sat on his lap. Lincoln widened his eyes as he looked up at her with a blush. Slowly, Luna grabbed the bottom of her shirt and pulled it off, showing her naked and breasts. "L-Luna! What are-" Lincoln felt a finger push on his lips to silence him. "Shhh, trust me bro~." Luna smiled as she moved down. She pushed his chest up, kissing and licking his stomach before grabbing at his underwear. "L-Luna stop...we can't...I'm your-" "You're my brother...I know Lincoln...but I want you~." Luna smiled up at him before pulling his underwear off.

"Holy...fuck~." Luna grabbed his member and laid it on her face, biting her lip seductively. It was huge, almost comically. All fifteen inches of limp meat lay on her face, her eyes staring at it before her tongue slathered on the side. Lincoln's cock twitched slightly, a soft mumble escaping from his lips. Luna continued her oral assault, licking up his shaft and all the way to his tip before forcing it down her throat. Forcing herself down, she grabbed his thighs and pushed more and more onto his cock. 'He's filling up my entire throat!' Luna thought as she deepthroats her brother.

Shocked at such a taboo sight, Lincoln couldn't do much other than grab onto the pillow and groan softly. His eyes staring at Luna's face, who occasionally looked up to him with an expression of love. "This is so wrong..." Lincoln repeated quietly, but deep down he knew he was enjoying this. Such a taboo act they're in, and Lincoln wanted to keep going. Suddenly, Luna pulled off and coughed out. "I-I'm sorry bro...y-you're just too b-" Luna was cut off as Lincoln grabbed her head and forced his member down her throat once more. Tears pricked at the punk rockers eyes as she grabbed his legs, gagging and moaning out. This feeling of being used...it was intoxicating. Lincoln's log forced itself in and out of her throat, soft grunts leaving his mouth as his member twitched and throbbed.

Luna tapped at his leg, but Lincoln wasn't done just yet. He flipped them over to where he was on top, forcing Luna's head on the bed. Her eyes leaked out tears of pleasure as Lincoln repeatedly thrusts down her throat without any remorse. It wasn't long before he let out a heavy grunt, forcing his dick as far as it will go and busting his load. Luna rolled her eyes back, feeling the thick and hot load roll down her throat. Pulling his dick out, her brother shot out a few ropes of sperm into her mouth, letting Luna taste it. Lincoln sat back, letting Luna cough and catch her breath.

"F-fuck! Lincoln...did you always have that in you?" Luna asked as she looked up at him, having swallowed his load. "Sorry..." he looked down, but Luna rubbed his cheek. "Don't be...I like it~." She smirked, making her brother blush. Soon she laid back down, removing her panties and finally letting Lincoln bask in her naked glory. While she had a killer rack, her ass was the main sight to behold. So big, it was a miracle her skirts were able to hide anything. "Lincoln...I'm afraid we'll do something crazy...so please put it here." She held her legs up, spreading her asscheeks to reveal her black cherry. The poor man blushed as he looked at his sisters sex and asshole, both so enticing. "Luna, you sure you want to continue?" Lincoln asked.

Luna smiled up at him, her heart fluttering excitedly. "Lincoln...I've never been so sure about anything. I know this sounds weird...but you're the one for me. I don't want anyone else but you~." She told him, her fingers rubbing her clit in anticipation. 'Here goes nothing...' Lincoln thought to himself as he moved over her, pressing his penis tip on top of her ass and slowly began to push in. Luna grabbed his arms, wincing and panting as she felt his member push in deeper inside of her. "Oh shit! Big! Too big!" Lincoln stopped at the sounds of her cries, only for Luna to wrap her legs around his waist. "I-i didn't say stop!" Luna panted as she starts to kiss and suck on his neck. His arms held her close to him, pushing in until he completely filled her up.

Once in, Lincoln's hips seemingly moved on their own. His massive cock repeatedly pounding into Luna's ass. Each slam into her made the rocker yelp and moan out, sucking on his neck hard enough to make a hickey. Lincoln's mouth fell to her breasts, gently biting, licking, and sucking on them. Luna's entire body felt shaky, giving into the waves of pleasure that came from each smack. "F-f-fuck! Yes! Lincoln keep going! OH FUCK I LOVE YOU!" Luna's legs fell off as her entire lower half went numb, only feeling Lincoln's cock enter her ass.

Lincoln panted and grunted, grabbing her hands and holding them above her head as he thrusts as hard and as fast as he possibly could. Luna's face, covered in sweat, turned to a "fucked silly" expression, her mind only thinking of her brother. Suddenly, Lincoln stopped, only to give three hard thrusts before slamming in. Luna's entire body became euphoric as she felt an enormous load of cum fill her up. Only letting out soft pants and moans, the two stayed there. Their sweaty bodies conjoined for the longest time before Lincoln pulled out.

"Hehe...my butt...is so...tingly~." Luna replied in a pleasure drunk stupor. Lincoln laid next to her, holding her close to him. The punk rocker happily snuggled into his chest, kissing his chin softly as sleep took her over. Lincoln looked down at her face, a look of nervousness being replaced with a soft smile as he kissed her head. This was a terrible idea, but by his word they're going to make it work. He was the comfort his sister wanted.

(Epilogue)

"Musical Mistress?" The boss asked as he looked at the drawing Lincoln made sent via email. "Yep, thinking she could be Ace Savvy's sidekick...turned love interest." He coughed a bit at that last part. Musical Mistress herself was adorned in a purple short dress, with various musically inspired gadgets on her dress and chest. Holding in her arms was a guitar that was said to be able to let out a sonic boom to stun opponents. With a nervous look, Lincoln waited for his boss's decision. "Hmm, I like it. But I'll have to tell the others about it. I'm not promising that she will be able to be in the main continuity, but with these "alternate" stories we're working on, I think we can fit her. Good work Lincoln." His boss told him. After saying goodbye, Lincoln shut off the video feed. He leaned back into his chair and gave an air fist bump.

"Inspired bro?" Luna asked. Turning behind, he saw his sister/lover leaning on the door frame. "Because of you yeah." He smiled as he stood up, walking over and enveloping her in a hug. "You know we can't tell anyone about this..." Lincoln said. Luna smiled sadly. "I know...but if that's what it takes...I'll take this chance..." she said as she rubbed her face into his chest. Lincoln kissed her head, holding her close to him. "I love you...my Musical Mistress."
