Chapter 40:
Understanding

...

Roy was going to kill that plumber the second he sees him again.

After Wendy had told him the whole story, he started pacing around out of frustration and anger. He couldn't really believe his sister had actually fallen for the green plumber. Sure he was 'nice' and all, but still he was the enemy. That alone should have discouraged her.

"Roy, please calm down," He pause and turn to his sister who sitting on his bed.

"Calm down?" He said frustrated. "How can I calm down when my little sister is throwing her life away over some stupid plumber? I mean do you even know what will happen if Bowser founds out; he'll disown you in a minute."

"I know that Roy," Wendy said "which is why we been keeping it a secret in the first place."

Roy let out a weary sigh. "Why?"

Wendy frowned, "Why what?"

"Why him?" He asked. "You dated a number of guys, why did you have to pick him?"

Wendy sighs tiredly. "Roy, you and I both know those guys don't care about me; only my title. Luigi loves me for who I am."

"Love?" Roy scowled. "How do you know he loves you?"

She smiled. "He said so himself."

Roy's scowl deepens. "How do you know he's not just saying that to get what he wants?"

Wendy shook her head. "He's not,"

Roy raised an eyebrow. "How do you know?"

"Because...I offered and he declined to it."

He blinked and leans back in surprise. "You offered?"

"Yup," she nodded.

Roy growled but didn't say anything to that. After a moment of silence, he gazes back at her with another question. "Do you love him?"

Wendy didn't say anything. She turned her head slightly to think of an answer. Roy waited for her response, a bit edgy and nervous. After a few minutes, Wendy turned back to him with a reply.

"I don't know," she said honestly. "It's too soon to tell."

Roy sighs and reached for his glasses. Once they were off, he ran a hand through his face and head. Gently, Wendy took his hand and held it tenderly.

"Please don't tell anyone, Roy," Wendy pleaded. "I know our relationship may be odd, but it is working. And if we were to broke up, I want it to be from our own choice not by others."

Roy glanced up and matched her blue eyes with his own. He could see how sad she was and how much she was pleading with him through eye contact alone. After a while, he broke it by turning away.

"Fine," He mumbled. "I won't tell anyone."

Wendy beamed and lean in to give her brother the biggest hug she can muster. "Thank you,"

Roy smiled and wrapped an arm around her. "Yeah, well, what kind of brother will I be if I left you to live off the street?"

"True, but even if you did, I'm pretty sure Luigi will offer to take care of me."

"Speaking of which," He release her from his hold and gave her a firm gaze. "I think I'm going to need another talk with your...boyfriend."

...

...

Luigi had made it home long before the sun started to set. His visit to the castle wasn't lengthy. He wasn't in the mood for company anyways; he only came to see how the princess was faring. And after seeing her going well, he excuses himself to leave, stating that he had some things to tend to.

When he got home, he landed on the couch with a heavy thud sound and a dishearten sigh. He just laid there as he blankly stared up at the ceiling. His thoughts, of course, were on Wendy and their relationship. Although it didn't last as long as his previous one, he had gotten more progress in almost half the time. Now it was probably over.

He let out another depress sigh. He felt a familiar void inside him, knowing he wouldn't be able to see the girl he loved. People will think he went insane to have fallen in love with a koopa, much less the koopa princess. But regardless of what they say, he wasn't crazy because he knew the pink koopa more than they could put up with.

He laid on the couch for a few hours before a knock came on the front door. He ignore it, not feeling well to talk to anyone. Unfortunately, the knocking kept going and got louder. Unwillingly, he got up from the couch with a grunt and sluggishly walked over to answer the door. Upon opening the door, his downcast expression immediately brightens when he saw who it was.

"Wendy! You're here,"

The koopa, now turned human, smiled upon seeing him. "Yes, I am."

"And so am I, jus' ta let you know."

The plumber jumped when he saw someone else appear next to Wendy. He was a tall, handsome young man in his early twenties. He had tan skin, short rough pink/purple hair, and hot pink sunglasses, wearing a pink sleeveless shirt that reveals muscular arms, black pants, black shoes, and spiked waistbands.

Luigi blinked; he didn't know who this guy was or why he was here with Wendy. "Uhm, sorry, but who are you?"

The man gave him a familiar looking smirk. "Can't recognize me, uh plumber-butt? Here's a hint; we saw each other dis mornin'."

Luigi blinked and widen his eyes. "...Roy?"

"You bet your ass it's me. Now, are you goin' ta let us in or what?" he said impatiently.

Uh, sure,"

Luigi steps aside as he allow both koopas-turned-humans inside his home. Once they were inside, he closes the door behind them and turns to face them anxiously. Roy looks around the house with little interest before turning his attention on the plumber.

For a moment, none of them said a word. Wendy stood in between her brother and her boyfriend as the green clad man fiddled in his spot nervously as the pink clad man stared at him with a blank, tense stare. After a few minutes of silence, Luigi finally spoke.

"So..." he started slowly. "What brings you guys here?"

Roy 'humph' before stepping forward, "I need ta talk ta you, plumber, about you and Wendy"

Luigi frowned but nodded understandably. Roy turned to his sister. "Wend, can you give us a minute?"

Wendy gave Luigi a quick glance before nodding. She headed upstairs and waited in Luigi's room to let the boys talked. Once she was gone, Roy turned back to the plumber in front of him. He sighed,

"Okay, look" he started. "I'm not gonna tell anyone about your relationship wit' Wendy so you could stop worryin' about dat."

Luigi blinked. "You're not?"

"No. Fo' some reason or another she likes you. And unlike those other guys, you actually make her happy. Although you don't fall under my ideal of the perfect mate fo' my sister, in da end, I guess dat's all I can ever ask fo' when it comes ta her."

His voice turns harsh. "But if you ever hurt her in any way, I will personally hunt you and wish you were never born."

"Trust me, Roy; if I do hurt her in any way, I'll come to you and Bowser in person." Luigi replies. "Wendy's your sister and I'm guessing the only family you got left."

Roy narrowed his eyes behind his glasses. "How did you know?"

"Wendy told me you all were adopted and that only a few of you were actually related." He smiled slightly. "Out of all the other Koopalings, you are the only one to show the most concern for Wendy. Plus I saw a picture of you and her when you were younger."

"Yur not as dumb as I thought" Roy commented. "Yur right, Wendy and I are related by blood; the same goes fo' Lemmy and Iggy. Wendy was over a year old when we lose both our parents. We had ta move ta da Koopa Kingdom 'cause da orphanage there was betta suited fo' us."

"You and Wendy were close as kids. Trust me, Mario and I were the same way. It's hard to let someone go, especially if it's to someone else. But believe me when I say this... I do love Wendy with all my heart and I will do anything to keep her happy, even if I have to let her go."

Roy raised an eye brow. "Really? How about dat Daisy chick you were wit' befo'?"

Luigi pause for a second, just a quick second, before replying to his question. "I still care for Daisy, but only as a friend. Wendy is the one I love now."

"Is dat so?"

Luigi smiled. "I may not really be a koopa but my word still stands. And that includes what I said earlier."

Roy frowned. "About what?"

"About you and Kastoadra,"

Roy snorted. "Jus' because yur relationship somehow worked, doesn't mean it will work fo' others."

"Well, you never know until you tried."

"Yeah, right," Roy sighed and ran a hand over his hair. "Look, I didn't come here fo' advice; I came here ta reach an understandin' between da two o' us. So..." He let out a hand for Luigi to shake. "Are we cool?"

Luigi smiled happily and took the offer. "Yeah, Roy, we're cool."

"Good,"

"Is everything okay?"

Both man looked up at the stairs where Wendy stood. She had gotten nervous because everything downstairs had been quiet, which was unusual when it comes to her normally loud brother. She came down to check on the two, hoping they (mostly Roy) didn't kill each other. She sigh in great relief when she saw them shaking hand, meaning they were getting along fine.

"Hey sis," Roy greeted. "Yeah everythin's fine; we jus' came ta a neutral understand."

"That's good,"

Wendy came down the stairs and walked over to Luigi where she wraps her arms around his shoulders and gave him a kiss. Luigi replies to this by putting his arms on her waist and kissing her back.

"Uh, hello; I'm still here," Roy interrupted.

The couple paused and turned to him. "I thought you say you were okay with us together."

"I am, but dat doesn't mean I have ta like it," He scowled. "I'm out o' here; I'll see you two later."

"Okay, I'm sleeping over with Luigi tonight so don't wait up."

"Don't worry, I won't."

The pink wearing man headed towards the door to leave, letting Luigi and Wendy to resume with their make-out session. With the door handle in hand, Roy pause by the door and look back at the couple.

"Oh, and Luigi,"

Luigi pulled softly away from Wendy and turn to him, "Yes?"

He gave him a smug look. "Next time I see ya, I'm gonna be kickin' yur ass extra hard."

Luigi gave him a smug look of his own. "I'll be looking forward to it."

Roy smirked and exited the house fully. Now that they were alone, Luigi and Wendy carry on with what they were doing. Mindlessly, they find their way to the couch and lay there for a couple of hours.

~XXX~

The sun had already started to set Mario when made his way back home. Earlier in the castle he had notice his brother acting a bit depressed. He did well on hiding it, he almost missed the signs. But before he could confront his brother, he left before he could get the chance. He figured the cause of his brother's distress was connected with Lady Fettuccine. Of course, that was a guess and he'll have to ask Luigi to confirm it.

As soon as he saw his house in view, he walked straight towards the front door. He notice the door was unlocked so he turned the door knob and enter inside, announcing his arrival and completely unaware that he was walking in on something private.

"Hey Luigi, I'm...home?"

He paused at the site in front of him. Lying down on the floor was Luigi with Lady Fettuccine sitting on top of him in what seems to be a very sexual position. His younger brother looked very happy to be pinned down by his red-haired girlfriend as they engaged in a heavy make-out session. They quickly turn at the sound of his outburst and froze once they saw him.

For the moment, nobody moved or said a word. A red blush appeared on Luigi's cheeks; embarrass to be seen like this. He and Wendy had fallen off the couch a while ago with her falling on top of him. She quickly took advantage of their position and pinned him down underneath her. By now, Luigi was used to this and they resumed on without much of an incident.

After a whole minute of silence, Wendy scorned the red plumber. "Ah, Mario; in case you haven't notice, but we're kind of busy here,"

The red plumber blinked in surprise and grinned, "Sorry, I came by to check on Luigi. But since you're here, I'm sure he's doing fine now."

He turns and head back to the door. "I'll sleep over at Peach's place so you two can have the house to yourself."

He opens the door and exited. Before he shuts the door, he looks at his brother and gave him a smug look. "Oh and Bro...?"

Luigi swallowed. "Y-Yeah..."

Mario smirked. "Be careful and have fun,"

With that said the red hero exited the house completely and locked the door as well. Luigi groaned and let his head fall back. Wendy leans forward and place a gentle kiss on his lips.

"You know, all this fooling around is making me hungry,"

Luigi opened his eyes and glance over at the clock hanging on the wall. "I guess we have been at it for a while,"

He got up and helped Wendy to her feet as well. "Come on, I'll make us some dinner."

The two head for the kitchen where Luigi made dinner for two. By the time they were finish, the sun had long since set and the moon was shining in the sky. They wash the dishes together, and decided to turn in early.

Without warning, Luigi sweeps Wendy off her feet in a princess carry, (most commonly known as the bridal style). The koopa princess squeak in surprise and wrapped her arms around his neck. Once they both were settled, he started up the stairs. After some difficulty of climbing the stairs while holding someone in his arms, Luigi carried his girlfriend into his room, where he kick the door shut for some privacy.

"Ah, come on Bro," Mario said. "It's obvious you both like each other. I do mean 'like' each other. And you both find each other physically attractive. Not only that, but she slept here for like... What, four times already?"

'Five if you count that time before we started dating,' Luigi thought.

"Plus, you slept over at her place for more than one night. Don't you think by now it's time you two finally hit home run?"

...

...

The brothers were discussing on an entirely different topic by the time Wendy reappeared, full dress and ready for the day. Both her and Luigi sat down at the table and started eating as Mario finish up what's left of his breakfast.

"Say, Lady Fettuccine," Mario said, starting conversation. "Have you ever thought about banging my brother?"

"Mario!"

...

...

"No Mario, we're not"

"Are you sure?" The red man pushes on.

"Yes, I'm sure."

"Then why is your girlfriend here wearing nothing but your shirt on?"
