Waiting to get Fucked

"There now, you sit tight, and be a good girl.  I'll be back to check on you in a bit."  MPHHHH!!!!!  As he tied her up, she could clearly see (and feel) his massive erection.  She knows that when he comes back to "check on" her, he is going to fuck her.  She tries to get free, but he tied her too tight.  All she can do is sit there while he robs her blind and wait to get fucked, knowing there is nothing she can do about it.
