Devin is pissed.  Seems her little slave boy Mark has been going out, fucking hookers.  Well, she's gonna teach him a thing or two or three.  Punishment includes a lesson in humility, as he's forced to kiss and lick her pretty feet and gorgeous natural breasts.  The angry Mistress harshly attaches mousetraps to his nipples and scrotum, and later a slew of clothespins, whipping his worthless ass.  Ultimately he gets a dildo up his tight little asshole.  Judging by the boner he has throughout, it all is well-enjoyed.
