No problem

Doe glances at you as if to get your approval. "Go for it," you say. "If you do it, we're that much further ahead."

Claire pipes up, "I think it's fair that if she doesn't succeed, you both forfeit twenty points."

You shrug. "OK," you say, "but I think she can do it."

Chris drops his pants, exposing his fully hard cock, and Doe walks over to him and gets down on her knees. Claire grabs the stopwatch and says "Ready... Set... GO!"

Doe takes his cock into her mouth, sucking and stroking. She uses her hands to jerk his cock as she's bobbing up and down. She slobbers all over his cock as she sucks him. After he's good and wet, she starts jerking his cock furiously while licking and nibbling on his nutsack. With a grunt, he starts shooting his load. As stream after stream of jizz shoots up, it drips down Doe's hands, and onto her face and hair as she finishes milking him dry. "Thirty seven seconds," Claire announces.

Claire tosses Doe a towel, and she wipes Chris's spunk off of her. "Now who doesn't have any stamina, asshole?" Doe asks Chris sarcastically as he turns red as a beet.

"What, you forgot how to swallow?" Chris demands.

"I only swallow John's load, not yours," she says, throwing the towel at Chris.

Claire interrupts with a wave of her hand. "We're wasting time here," she says. "The next event will be in the gymnasium. You have 6 minutes to get there, starting... NOW!"

You and Doe start running across campus, and, being the faster runner, you slow down to match her pace. Still, you make it there in four minutes.
