sounds perfect...wouldn't want to let the younger slave get too confident/cocky thinking that she was anything more then a slave or fuck toy the way Marie is. After all at the end of the day, they both have tits and cunts and are nothing more then property for us to enjoy. I could see after an afternoon of working Marie over and letting the 21 year old slave (I haven't come up with a screen name for her yet so for now I only call her my slave or the slave...I have a few ideas though for her screen name lol) act more alpha I would bring them both outside and make my slave lay on the ground and tell Marie to sit on my slave's face. That way Marie could return the favor it my slave had gotten a little too cocky thinking she was something more then a slave when she was making Marie gag on cock. Then enjoy a cigar and watch the two slaves, hell even have Marie hold the ashtray for us.
