Beth lets her

Smiling, but saying nothing Beth slowly glides the man's cock to Emma's mouth, and as she does Emma's tongue darts out, hungrily licking at his tip before parting her lips fully to take his head into her mouth.

As soon as Emma's hand came up, stroking the cock in her mouth, Beth let go, stepping back to watch her friend devour the man's shaft with a passion she didn't know Emma was capable of.

Slowly Beth walked around the man, standing behind him and grabbing at his shirt, pulling it up and over his head, suddenly leaving him completely naked from the knees up.

Smiling at her handiwork Beth circles them again, this time kneeling behind Emma and unzipping her skirt letting it fall to the floor circling Emma's knees as her head furiously jerked back and forth on the man's cock, giving Beth a view of her pert, sweaty arse, jiggling with her movements.
