I'm your sweet, playful little sister. I find you all tied up in your bed after your girlfriend left the house in a hurry. You beg me to untie you.. but I have other plans for you. I hate that disgusting, nasty whore of a girlfriend you always have a round. To be honest, I'm just jealous. But if she's ever done one good thing for me.. it's leave you here all tied up. Your cock nice and hard, and ready for me to finally fuck.
