Do or Diaper

At the park's house, (Y/n), Mordecai, Rigby, Muscle Man, Starla, Sam and Margaret are driving back from pizza. "Ah, stuff so good." Rigby said. "You can say that again." Sam said. "Mama mia." Muscle Man said. "Thanks for driving." Starla said. "Yeah, no problem." Margaret said. "Man, who knew pizza can be so good." Mordecai said. "Uh, that's kinda it's thing." (Y/n) said. "Go, go, go." Rigby, Muscle Man and Starla rush towards the window to watch (Y/n) and Mordecai.

"Shh, Shh. Come on, come on." Sam said. "No way man. No way." Muscle Man said. "Here it comes." Sam said. They watch as Mordecai and (Y/n) awkwardly hug. "Ugh!" Everyone said in annoyance except for Rigby who breaths a sigh of relief at this. "Ugh, man! Ugh!" Sam said in frustration. "Told ya." Muscle Man said. Muscle Man, Sam, Starla and Rigby sit on the coach, when Mordecai comes back inside, they stare at him. "So, what do you guys wanna do... now? What?" Mordecai asked. "That was painful, bro." Muscle Man said. "What was?" Mordecai asked.

"That. Uh, uh. Uh." Sam said. "You guys were watching me!? Ugh, geez." Mordecai said. "Dude, bro, when are you gonna seal the deal? You and Rigby have been like wanting to kiss (Y/n) for years now." Sam said. Rigby's eyes widen as he looks at him frantically. "Wh... what?! No I haven't, that's all Mordecai, dude." Rigby crosses his arms and Sam laughs. "What's so funny?!" Rigby asked. "Oh come on, Rigs, who do you think you're fooling? I know you both have a thing for her." Sam crosses his arms with a smirk. "What?!" The duo asked. "No, no we don't." Rigby said.

"Lies! I've seen the way you guys act around her. And don't think I haven't noticed how overprotective you two are of her. Not to mention how mean you both have been to her whenever I've tried to flirt with her or vice versa. You're both totally into her and you can't deny it." Sam said. "Stop talking! You don't know anything! We're best friends and that's it!" Rigby shouted. "But you'd like to be more than that, wouldn't you?" Sam smirked, and Rigby growls. "SHUT UP!" He shouted.

"Seriously, bros, Sam is right. Why haven't either of you made a move on her yet? Are you both just too chicken?" Muscle Man smirks. "You stay out of this, Muscle Man!" Rigby shouted. "Bros, you gotta make the moment. Watch. Did you have fun tonight, babe." Muscle Man asked Starla. "I always do." Starla said. "I hope you saved room for desert." Muscle Man and Starla make out. "Hmm, seems simple enough." Sam said. "Ugh, you guys don't get it! It's not easy for me. I try." Mordecai said.

"Really?" Sam raised an eyebrow. "I mean, I've had some chances in the past that didn't work out, but it's just gotta feel right, you know. Uhh, I don't know. I don't know what's wrong with me." Mordecai said. "Sounds like you both need some extra incentive." Sam said. "Yeah, like what?" Rigby asked. "Hmm." Sam laughs. "Okay, it's Sunday. If either of you kiss (Y/n) by midnight Friday, I'll wear a diaper for a whole week." Sam said.

Muscle Man laughs. "Good one, bro!" He said. "Whooa." Mordecai said. "Whooa, now we're talking!" Rigby said. "I'll even sweeten the deal. The two of you don't even have to kiss her, you just have to tell her how you really feel." Sam said. "What?!" The duo asked. "But of course, if neither of you can do either, you've both gotta wear diapers for the week." Sam said. "What?!" Rigby asked, sounding horrified. "Aw, what? I don't know. This is probably the dumbest idea I've ever heard." Mordecai said.

"Hey, you two already love her, right? So all you really gotta do is confess. Then you can laugh at me in a diaper. It's a win-win, dudes." Sam said. The duo look at each other with concern. Sam and Starla are smiling and moving back and forth. "Alright, we'll do it." Mordecai said. "Whooo! Oh, man! He got you good!" Muscle Man laughs and jumps on the table. "You could both be wearing a diaper for a week! They're never gonna do it! They're never gonna do it! Diapie time!" Muscle Man laughs and so does Sam. Starla and Muscle Man make out and leave. "Betting big time huh?" Sam asked.
