She eagerly jerks them off

Mackenzie smiled as the two men unzipped their pants and revealed their erect cocks to her. She firmly grabbed them and then proceeded to jerk off both men, and even gave each cock slow, seductive licks.

With the man behind her still fucking her ass, and no cocks to fill her mouth. Mackenzie let out several moans of pleasure for all of the crowd to hear.

“OH YES! OH YEAH! DON’T STOP!”

This led to both the men in front of her spraying their cum all over Mackenzie’s face. She just smiled and said “Who’s next?”
