Since Melanie is covering Ms. Chase's class this week, she is seated at her desk in the classroom. In search of Ms. Chase, an individual by the name of Ace Bigs enters the classroom. Melanie informs him that she will be filling in for him this week. I've been working on a unique project with Ms. Chase lately. How should I phrase this? Ace admits to Melanie, "Cory makes sure my step-son passes her class in exchange for me taking care of her needs and me taking care of Cory's. " Melanie, dressed in a purple shirt and black skirt, gets to her feet next to him. While telling Ace that she thinks she is capable of performing the same thing that Ms. Chase has been covertly doing with him, she swiftly takes off her purple shirt. Melanie approaches Ace on her hands and knees, giving his BBC a hard time. After giving him a few minutes of hell, she leans against her desk and assumes the doggie position. Ace starts to penetrate her pussy from behind as he lifts up her skirt. Her large tits twitch in response to each push from behind. Next, she positions herself as a missionary on the desk. After extracting his cock from her pussy, he stoops down and briefly nibbles her pussy. After that, he re-inserts his BBC into her pussy. Melanie gives Ace another blowjob as he settles into the teacher's chair. She simultaneously uses her mouth and hands. He then uses his BBC to fuck her pussy for a few more minutes while she returns to the missionary position on the desk. He bursts inside her pussy when he is ready to cum! A small amount of his smooth, white sperm leaks out of her taut crotch. Melanie yells, "I'll cover for Cory's class whenever she wants!"
