This housekeeper deserved to be treated like that - she walks around there twisting her ass and throwing her balls around too. So he poked her in the mouth hard. Apparently her pussy was so on fire that the blonde lost her fear. Even her friend helped to hold this bully so that the master could cum all over her throat.
What an interesting relationship the brother and sister have, not shy or anything, judging by who they did it next to. But their mother's reaction was amusing.
