Ass for ass

Emily gives Jack a coy look.

"Hayley keep sucking his cock."

You go back to it, slurping on his shaft and taking the whole thing down your throat. You leave a generous of coating on his cock as you come up for air.

Emily comes back into view, now fully naked and a bottle of lube in her hand. You have a pretty clear idea of what is going to happen next.

"Hey, I need to be ready for Jack would you use your fingers on me?"

You nod.

She hands you the lube and you coat it over two fingers. Emily lays on her back and spreads her legs, pulling her knees up to her ches.

You slowly insert one finger into her ass and watch her expression. She clenches her eyes shut at first contact, and then her mouth opens as you get all the way in. You hold your finger there and she opens her eyes and nods. You slide the second finger in and this time she just smiles, her eyes watching you through slits.

Jack gets up on his knees and pokes her mouth with his cock. She opens her mouth and accepts him in.

You slowly start to fuck her in the ass and she starts to relax and take it. At the same time her mouth appears to be doing a great job on Jack's cock. You lube up a third finger and slide that in.

As you continue to service your best friend, you get in close and lick at her pussy. She is soaking wet.

Emily pulls the cock out of her mouth:

"Okay, Jack I am ready."

You retrieve your fingers, and the two of them reposition so that Jack is lying down and Emily is positioned above him.

You watch as your best friend eases her boyfriend's cock into her puckered asshole.

"OH FUCKKKKK" She wails as his head 'pops' into her and is quickly followed by the rest of his shaft.

The two of them stay like that until Emily finally recovers and then begins to ride him.

"Babe, your ass is so tight."

"And your cock feels so FUCKING big."

Very soon Jack is pushing his cock into Emily and she is just hovering over him and taking it.

The scene is making you incredibly wet.
