Beth wants it

"No," Beth says teasingly, slowly kneeling down in front of the stranger. "You've already had your turn."

Emma looks in shock as Beth wraps her fingers around the Stranger's cock, jerking it slowly back and forth before finally moving her head closer, parting her lips and running her tongue along it's length.

The Stranger for his part let out a gasp of pleasure, looking down at Emma's near naked body as well as the beautiful blonde kneeling at his feet, her mouth working his cock.

His mind suddenly goes blank as Beth lowers her head completely over his shaft, his cock pushing between her lips and deeper and deeper into her mouth, hitting the back of her throat, drawing a noise, half gag and half moan of pleasure from Beth as her tongue flickers around his shaft, her head jerking back and forward along it.

Emma couldn't believe what was happening. She was kneeling in the library restroom in nothing but skirt and stockings watching her best friend suck a strangers cock. Not only that, but she had been begging for it moments earlier and could once again feel almost intoxicating levels of arousal flooding through her body. Idly her hand slid down between her legs again, toying a little with her brown pubic hair as she watch Beth work.
