Take the front.

Julia seems to be waiting for you to make a choice, so you hurry to drop to your knees in front of Rachel since you're pretty sure you don't want to taste Rachel's ass. Julia takes up her place behind Rachel and immediately dives in between her cheeks. It's fairly clear she's done this before. Rachel swivels her hips sexily to give Julia's tongue more penetration.

Then she grabs a hunk of your hair and pulls your face into her pussy. "What are you waiting for?" she barks. "This isn't a peepshow."

You begin kissing and licking Rachel's pussy just like Ella showed you. You're surprised at how much you like the taste of her and you find yourself rather enthusiastic about the task. You and Julia soon have Rachel moaning and thrusting her hips to get each of your tongues deeper alternately. Soon enough, she has you concentrating on her clit and Julia is more or less forgotten. "Oh God," she says, "that's it. I'm going to come." She tenses up and gives out a loud, low groan as she bucks her hips up against your face and grinds her pussy into your nose and mouth.

She lets you both go when she's done and Julia crawls between Rachel's legs and surprises you by giving you a long tongue kiss, which makes you a bit uncomfortable considering where her tongue had just been. She whispers in your ear, "You know, Parker, I'd really like to go shopping with you tonight if you're not too busy."
