Sam and Sonia "The Favor"

You are in the living room when you hear a yelp from your mother in the bedroom. Then you see your brother running down and past you

Sam

Runs past you with a panicked expression. He looks at you and whispers urgently

“Bro…cover me on this one…mom would kill me if she found out…but we all know she would probably forgive you. Please, if you do this… I owe you a favor. Whatever you want from me.”

Before you can ask any questions, Sam already bolted out of the house

Sonia

Your mother comes down from upstairs, notices you, and presents you with a pair of cum stained panties with a flustered and frustrated expression

“Are you freakin kidding me? My worn panties? This is disgusting! Do you know anything about this?!”
