Olivia stood at the door quiet as a mouse. She was alot braver then before and she slightly peaked around the door to watch the act. The two going at each other so open and unknowing of her presence, had her worked up far more then she expected. She gazed behind her and checked down the stairs. With nobody else around she returned to her hiding spot. Watching the two collide over and over Olivia found her hand sliding down towards herself. Unable to really move her hands around she quietly as possible slid down her pants. Just at her thighs at first.<br/><br/>Olivia started to tease herself softly rubbing on her clit as she watched to two in the bedroom. When she opened her legs a bit more her pants slowly started to slide down her legs. To busy to be bothered with it Olivia took in the moment and her naughty actions. Her breathing getting labored as her pants finally fell to her knees and eventually down to her ankles.<br/><br/>She kept as quiet as she could listening and peaking in from time to time.
