Alex Coal helps friend's brother study by giving him a fucking reward

Though he seems preoccupied by her attractiveness, Alex Coal is attempting to assist her friend's brother in his studies. Alex then has a brilliant idea. She creates some flash cards and vows to take off one item of clothes for each correctly answered question her friend's brother gets. She's surprised that he handles them all well. Since Alex is currently nude and her friend's brother is having a hard time, Alex rides that dick till it gets in her throat, which helps to diffuse the tension.
