After their sexcapades the previous night, Blair, Jo, and Nat have been grounded by Mrs. Garrett. They have a tutoring appointment and Nat is instantly possessive about which guy she's going to fuck. She winds up choosing Johnny to "study" with, while Blair announces the boys will need to prove their worth to her. She pairs up Johnny with Blair and Willis up with Jo, telling the group that whichever man proves himself the best gets to go to the bedroom with her. Nat is all for it and is soon on her knees sucking Johnny off. Meanwhile, Jo makes it clear she's not interested much to Willis's chagrin.
After a close call with Mrs. Garrett, Nat comes up from beneath the table and flips her miniskirt up before guiding Johnny's hand to her juicy twat. Jo can't pretend her lack of interest any more, so she lets Willis feel the wetness in her own snatch. They relocate to the living room for the contest. Nat quickly sheds her clothes and hops onto Johnny's dick while Jo takes her time enjoying Willis's big dick in her mouth.
Now the competition can really begin, with Nat and Jo each riding their respective partners in reverse cowgirl as they thrust their hips to get themselves off. The girls each get down on their knees doggy style, then roll onto their backs. Jo may have been a bit of a dark horse, but Willis is easily able to cum on her stomach. Meanwhile, Nat finds herself needing to give Johnny a handie to get him to his finish line. When Blair returns to the room and sees that Johnny hasn't cum yet, she declares Willis the winner and leads him to bed.
