Gross! I stepped in gum at a festival, fix this with your mouth, slave

Description: Portia has just returned from a massive outdoor music festival. she has a disgusting mix of chewing gum and mystery filth stuck to the bottom her sneakers. but portia couldn't care less; her obedient slave will clean it all off. she stands over her slaves face as he licks away at the sticky mess until his tongue is raw. he then reverts to using his teeth to scrape the the gum out from between the tread. it is embedded with dirt, little stones, grass and hair, all of which must be swallowed. portia attaches electric clamps to his nipples and begins shocking them repeatedly to encourage her slave to work faster
