They can't help it

As Zack saw Ashely bend over one more time , he couldn't help himself anymore and wrapped his arms around her waist.

"Zack.. We can't do this again..ah" Ashley moaned at the last minute as Zack started nibbling on her neck, leaving a mark.

"Ashley, no one has to know about this..just let yourself go" Zack whispered against her ear as his hand went lower.
