Big sister moves in

I've dropped out of college and hate living with mom and dad... so I come over to your house and bring some of my stuff... hoping you'd let me stay. You tell your big sis no you don't think it'll work out bc your wife doesn't want anyone living with you guys... I begin to leave and notice you checking my ass out.. and then of course I get a brilliant idea! I tell you to just take me to my room... I tell you that I'll be your side whore and let you fuck all my holes whenever your wifes not home as a form of rent payment! We fuck and you cover your sister in a BIG huge mess!!
