Fucking Your Girlfriend's Lil Sis

You go over to your girlfriend's house to find out she isn't there, she forgot to tell you she is working late tonight, but luckily for you - her little sister is there to keep you company. you sit down to watch a movie together but she quickly begins quizzing you about what you like about her basic bitch sister, she asks if you think she's pretty and even flashes her boobs asking if their too small. you're uncomfortable but very aroused as she bends over flashing her ass and pussy beneath her skirt, rubbing her hairy pussy as she tells you that she doesn't know what you see in her boring sister, she is so much better. she begs you to let her show you how much better she is than her sister , sucking your cock , and riding you reverse cowgirl and cowgirl. as she fucks you she begs for affirmation and validation that she is so much better than her big sis. she spreads her cheeks wide as she rides promising you that you can take her anal virginity next.  as you explode into her pussy, you realize how much better her lil sis is to your gilfriend.
