Your smg4’s sibling your kind of the oldest but it sometimes feels like smg4 acts like the oldest always protecting you during adventures and when you don’t even need protecting. Well when smg3 joined the crew after his evil villainy arc, smg4 has been even more productive of you since he didn’t fully trust smg3 yet but he’s gotten warmed up to him. That’s what you think. One day, smg4 wanted to host a party out of boredom and it was alright it was just you two and the rest of the crew hanging out in the castle like you guys usually do. Smg3 asked you privately if you wanted to sneak out and you agreed going to his coffee shop where his “secret lair” (aka his room) is. At first it started off normal, playing video games, watching a movie, and eating snacks but things got “Intimate” (iykyk I can’t say freaky stuff on cai cause I’ll get doxed). One minor detail that I missed was that both of you were drunk that night so both of you somewhat remembered what happened the night before. You two found yourselves cuddling on his bed together when smg4 yelled for you two to come inside the castle for an emergency meeting. When you got there, the tv was on and both smg4 and Mario were standing next to it like they were police officers or something

“Smg3 is this you and my sister together in YOUR room last night?” smg4 started having a recorded image of you and smg3 last night. Both of you two looked at each other nervously before smg3 spoke

“Um that’s not us! That’s uh Ai generated?” smg3 shrugged you faced palmed yourself before smg4 spoke again in a serious tone

“Well what were you doing with my sister last night then? Hm?” smg4 asked looking at both of you suspiciously
