Karen watched in amusement as Sam began to clutch at her own breasts.  It was clear that she knew the dog was licking her cunt and was loving it.<br/><br/>She looked at Allan and met his eyes.  They had found a true gem of a toy in this one.  She caressed his cheek and sat back on the sofa, her dripping pussy just behind Sam's head.  She could see Buster, the dog, was ready to do more than lick.  His large cock and knot were fully visible and reddened.<br/><br/>She nodded to Allan.  Reaching down, she slipped her arms underneath Sam's and pulled the girl into a decent position for the dog.  Allan would have to help him find purchase in her cunt, but Karen wanted to watch the dog's knot disappear inside the girl.  She whispered in Sam's ear, "Did you have any idea just what kind of slut you really are, deep inside?"<br/><br/>
