The dungeon BDSM master is teasing his submissive slave. Whipping, caning, and hot candle wax were just part of the exam. A more carnal part was also part of her exam and she would have to be a perfect submissive slut to succeed. Sucking and gagging on a big cock was a bit difficult, but her pussy was more than happy to fuck that enormous cock. She was not certain is everything would end up well but when she faced a huge facial cumshot and a mouthful of cum she knew she had passed the exam with distinction.
