After an intense workout, busty redhead Sweetie Fox gets a surprise when Black Bull, her personal trainer, decides to put her through a different kind of training. He starts by making her deepthroat his massive cock, pushing her limits with rough, face-fucking. Then, he bends her over in her gym leggings, spreading her perfect ass to admire her tight hole. He pounds her in doggystyle, her big tits bouncing with each thrust, until he replaces his cock with a glass butt plug, making her moan in pleasure and pain. Finally, he returns to her ass, fucking her hard until he creampies her, leaving her breathless and satisfied.
