Big Bad Sister PT 3

I was going to sneak out to see My boyfriend, but I will NOT have you rubbing off and telling on Me. So you are going to sit in My closet and keep your dirty little mouth shut! Big step-sis has to keep an eye on her little twerp step-brother. If you make a peep or any movements, I will beat you down into the ground. Beside, I told you I was going to show you how to suck dick. Since it's unquestionably your future haha. Anything else you see or hear, you keep to your fucking self! Or else.
