Have fun with your sisters

While you're planning your next move, two hands suddenly comes out of nowhere and cover your eyes.

"Guess who it is ?" says a high-pitched voice.

"Abbie, I know it's you."

"Wrong ! I'm Lizzie !" she responds, laughing.

Abbie and Lizzie, your two younger sisters. They're identical twins and you've always had trouble differentiating them, the only hint that you have is that Lizzie has slightly bigger breasts than Abbie, but that's about it. They're really close, to the point where they share the same bed.

She removes her hand and you can see clearly again, you see two small and adorable brunettes with blue eyes. Lizzie is wearing cut-off shorts with a tank top, while Abbie is wearing skinny jeans and and a plain t-shirt.

"So, bro. What are you going to do today ?" says Abbie

"Eh, I don't know. Maybe watch TV all day, how about you, girls ?"

"We don't know either, we're boooored..." they say in unison

"Well, we could do something together !" you propose

Devilish ideas come to your head. This could be fun.
