Mom and sister are enslaved.

   So, it is evening and you have mom dressed in a tight fitting dress, modest of course, complete with heels.  Your sister, ripe and shapely, is bent over the armrest of the couch.  You have your totally hypnotized mother with a wooden paddle and smiling at you.  It is sheer pleasure for you to hear her address you as, "Sir," as well as tell you how proper and correct you are in your decisions.
     Your sister!  Ahh!  Is this the same one who used to borrow your sports car without your permission, because mom said it was okay as she handed her your keys while you slept from working your shift work job?  Oh!  This was almost too good to be true!
     Your darling sister is dressed in a full body girdle, thigh high hosiery and heels.  You have her resting her arms straight as she bends over the armrest to the couch.  You command her to turn to you and utter the only words you have allowed her to say so far.  She looks at you with rosey cheeks.
     "I have never... ever been so embarrassed in my entire life!"
     As if this is the signal, mom slaps your sister's rear end with the paddle.  You count to three and so mum begins to slap your sister's buttucks, over and over.  After a while, what with the pressure from the form fitting, tight girdle, along with your command in your sister's ear, she begins to groan as her mother slaps her again and again.  As it would be, the pressure from the girdle, along with her little pussy getting gently pressed against the armrest, is causing your sister to squirm on the verge of an orgasm!  As you watch this display you decide your sister is breathing hard enough and is flushed in the face enough to have received the correct amount of pressure for the magic moment you are wanting her to have now.
     "Sister, say what I have told you to before and come hard as mom spanks you more.  Now!"
     "Ahhh," she starts out with as she gasps while her mother slaps her more and more.  "I ha-a-a-ave never been so embarrassed in my entire life!!!"  Immediately your sister bends over more and her legs quiver.  Soon, her bottom half is soaked as she presses against the armrest of the couch, all the while her mom spanking her more.
     All you can do is smile as she tell your darling sister to come again.  Through your hypnotic eyes you have gained vengence and leave your sister craving S&M.  After your sister is completely exhausted you tell her nap on the couch.  Your mother you command to go wash up and dress for the evening.  What a night so far!
