Mistress Natalia walks barefoot along the railways. Her Feet are very muddy and covered with railroad oil and other heinous stuff. She comes home and determine to make a truly hard challange for the slave. She tells Alex to licks and gulps all this mud. This is indeed disgusting but Alex will eat all this dirt. Slave licks and sucks every bit of Mistress Natalias feet but barely clean it. This stuff is really hard to clean. Anyway Alex swallows a lot of this dirt and mud and feels very bad on next day. But Mistress Natalia was happy.
