Sarah begins to lick your ass

You hold your erect cock up while slowly Sarah leans down with her tongue sticking out of her mouth.

You can tell she doesn't really like being in this position, but she feels like she has ****. She feels worse about cheating with your - her husband's best friend - than anonymous strangers. She'll have to keep seeing you around, look at you. And you'll both know what a slut she is.

Sarah's tongue presses against your puckered ass. At first it just tickles, but as she rolls her tongue up and down, teasing your hole, the pleasure begins to spread.

You begin to stroke your cock as Sarah presses her face harder in between your cheeks.

"Yes, Sarah. That feels good," you tell her and responds by licking your ass more passionately. Despite everything she wants to be good at what she's doing and it feels good to hear you responding to her nasty efforts.
