A masterful female slave trainer has got a request from her Mistress friend to borrow a slave, however the specifications for this particular slave are quite precise. The slave must be completely obedient, as is standard male, and their asshole must be thoroughly stretched out and trained. After reading these, the skilled Mistress gets to work, heading straight to the cage of the slave she has in mind. She informs the lowly slave, who deeply bows before her presence, but before he is off to her new Master, his asshole must be rigorously trained. The adept Mistress orders the meek slave to lie back with his ass hanging up in the air as she lubes up her gloved hand and inserts a finger one-by-one into his asshole. To her surprise, the man’s asshole ate up two of her fingers with ease, so the wicked Mistress picks up the intensity, fitting in all five of her fingers into the man’s stretching asshole, before plunging in her knuckles and then her whole fist, making the feeble slave moan as he tightly grips the bars on the bed.

Seeing that her loosened slave’s asshole is now ready for the next phase of her anal stretching exercise, the talented slave trainer puts on her gigantic black strap-on, which she wettens up by commanding her obedient slave to slobber all over it. Once properly lubricated, she orders the man to get on all fours, before jamming the huge artificial cock into his strained, thrusting it backwards and forwards, making the pathetic slave cry out in a mix of pain and pleasure. The twisted woman relentlessly thrusts into the man’s gaping asshole until he is able to take the entire black cock inside of him.
