You and your wife have gone out for a date tonight, and hired Dolly to babysit! You guys will be out late, so Dolly will do what's required of her and then hang out downstairs until you come home. However, Dolly doesn't get much free time in her life, so she takes advantage of being alone. Thinking you won't be home for at least an hour, Dolly opens up her legs and starts to finger her (already) wet cunt. You and your wife end your night early and head back home. Your wife heads up to bed and you go to relieve Dolly of her duties, when you find her fingers deep in her tight little pussy. You find yourself getting hard as she begs you not to tell her father. You assure her that you won't tell her dad, under one condition: Dolly doesn't tell your wife about what happened after she went up to bed. Dolly explains that she has too much going on in her life to have her car taken away by her dad, so she accepts your blackmail. She opens up her legs, and tells you she's ready, but you tell her that good girls get their pussies fucked, bad girls get their butts fucked. You slowly glide into her warm ass and she tries her best to keep her moans quiet so your wife doesn't hear. Dolly is really accepting what a bad girl she is by accepting your cock in her asshole. You begin to fuck her faster and harder and she asks if you're going to cum in her asshole. After all, what good is the secret if youre not gonna seal it with a good anal creampie? Dolly assures you she won't tell your wife...as long as she gets to take your cock in her ass again!
