It was just an evening where Waluigi would come over, bug Luigi, and go home. That was just it.
But things changed whenever Mario was out, making this a lesser challenge. Things changed whenever Luigi jumped up from the couch to grab the remote and shut off the TV, blushing as he did. Things changed when Waluigi leaned over and saw that his cousin had been fiddling with a rose and a glass of wine while he was watching his romance movie.
It was enough to make things change.
Luigi quickly started to snatch up the rose and wine glass, muttering a speech about how Waluigi should at least get a girlfriend or go out drinking and stop bothering him.
Waluigi just stood there, arms tightly folded against his chest as he looked down. Truth was, he had seen a little bit of one of those cheesy romance movies a few hours before he decided to come bother Luigi. That little bit of watching made him think about said relative of his.
Luigi started to defend himself after Waluigi questioned the occasion, making up excuses while he did. He was bored, he felt like having wine, nothing else was on TV, the rose was just there.
Waluigi just sat down on the couch, waiting for Luigi to get back from the kitchen. He just stared at the blank TV screen, imagining himself as the shorter, sitting there, just watching it with a rose and glass of wine.
Five minutes later, Luigi was starting to try and convince Waluigi to leave, red still on his face. Mario would be home soon, Waluigi's oil company may be looking for him.
While there was all that hand gesturing and that head moving, Waluigi found himself entertained by Luigi. Not his voice, not his actions, not his looks, but just Luigi.
Right there, Waluigi felt himself want the shorter.
He made a sexual innuendo when he could; enjoying the look on Luigi's face when he heard it and pictured it in his head. He started to recline on the couch, trying to look as sexually inviting as he could.
Finally, Luigi threw his arms down in frustration and demanded to know what Waluigi wanted.
With a smirk, Waluigi got up and walked in front of Luigi, kneeling down so they'd be face to face. Luigi's face turned just as red as it could be, but then he said that it was hot in the room. Waluigi just said it was because he was in heat, with a wink, and reached around – successfully pinching Luigi's ass.
Waluigi never heard such a sexier gasp come from his rival.
The next thing he knew, he was pinning Luigi down on the bed, laughing as he dry humped Luigi's thigh and slammed their growing erections hard together.
Then he found himself dizzy, staring down at Luigi as his clothes slowly came off. Waluigi just wanted his cousin nude, right now, but then again it'd ruin the sex.
Before he could figure anything else out, Waluigi was enjoying that look Luigi gave him, his facial expressions as he enjoyed the thrusts of the taller, the sounds that escaped him as well.
Now, Waluigi was regretting it all. As he looks at Luigi while he is sleeping, Waluigi wishes that this wasn't how the night was supposed to end. He reaches over, poking Luigi on the shoulder, watching him blink awake and mutter the question of what was wanted.
Right then and there Waluigi wishes he could bite himself.
He'd fallen in love with his so-called rival.
