As one of her lowly servants, Lady Bellatrix has really been putting you through the paces and she thinks you are entitled to a reward. As it turns out, she has been wearing her leather boots all day and her fishnet clad feet are thus rather scented. Before she offers her perfectly pedicured feet for worshipping however she wants you to amuse her by begging for the honour.
When she is finally satisfied that you’re worthy she offers her big toe to you, nice and close. Smell it, lick it, taste it. How long will she allow you to worship these fine fishnet clad feet? Show your desperation!
