She has to beg

Emma looked up, watching Beth slowly stroking the strangers cock, and you pour more lust into her than she's ever felt before.

"Yes," the word escapes her lips before she even realises she's said it.

Still stroking the man's cock, Beth slowly beckons Emma closer, and Emma leans forward slowly crawling across the floor.

"Beg for it," Beth demands, reaching down to stroke the side of Emma's face, still jacking the man's cock inches from Emma's mouth.

A shiver runs down Emma's spine, her eyes locked on the cock in front of her. "Please," again the words seem to come involuntarily, "I want it."

"What do you want?" Beth asks.

"I want his cock," Emma continues, "please let me suck it."
