The young Mistress ordered her slave to lie under her and sit tight, otherwise it will be worse. Bertie wants to satisfy his thirst and play with this bitch, humiliate her properly, so she will cry and plead. The poor girl lies under her Mistress and cannot do anything. She also shoves her sweaty and smelly socks down her throat; Bertie is just out of the gym. Next, Bertie puts fingers into the slave's mouth and pushes them to the throat, so that the girl feels even more uncomfortable.
