"Take a seat and play with yourself."

"What?" Mackenzie was shocked by the proposal from her supposed 'Friend', it took her a few seconds to even process the demand.

"Hey, I saw you in that box, don't try to deny it." Willow raised her hands up and tried to feign innocence, but her smile betrayed her, Mackenzie wanted to deny it, but she could neither explain it properly nor really wanted to confess to playing with herself earlier, she figured it might be easier to acquiesce to the accusation.

"And besides, your nipples and lips can't lie," Willow added, and this in particular was something Mackenzie could not deny "All I'm asking you to do is do what you were going to do anyways."

It wasn't long before Mackenzie was writhing in pleasure as she approached a climax, moans began escaping her lips as she increased the speed of her fingers more and more, ass bouncing off the seat's wooden finish as her ministrations finally culminated in a thundering orgasm, back arching, groans echoing and copious amounts of pussy juice leaking on the seat, she finally settled down panting as her orgasm finally began to subside.
