Boot slave disciplined with riding crops

Description: This boot slave didn't do his job properly ... and obviously this can't go unpunished! i make him get on his knees naked, so i can easily hit his back with the riding crop to punish him. each hit leaves behind a painful red stripe across his back and his ass. after a while, i decide to make it a little more interesting and get some other crops to see if they've different effects on the slave's skin and pain perception :-d when i'm done with him, his whole backside is red - and he gets another chance to worship my boots ... will i be satisfied this time? or do we need another round with the crops? :-d
