You've just come to hang out with your friend at his house and knock on the door when his little sister answers the door to let you know he isn't home yet. As you go to leave, Dolly reassures you its still okay to come in and that she has things for you to do until her older brother gets home. She lets you inside, starts pulling out some of her records to show you, clears off a spot on the couch, takes off her shoes and tells you to come take a seat when she realizes that you've BOTH noticed she's not wearing panties! Dolly's feeling super embarrassed when your instincts take control and ask if she wants to fuck. She gets nervous knowing her brother would be totally pissed, but she can't help herself knowing you're one of the coolest guys in school! Then Dolly praises and slobbers all over your cock, sucking it deep down her throat, drooling and gagging all the way until she's begging to have it in her pussy. Finally she gets on top of your dick and rides you until you both cum, leaving her a wet, sticky mess. But she doesn't mind, what nerdy girl would?
