She swallows!

*Gulp*

*Gulp*

*Gulp*

It actually took her four gulps to get everything down. As she's done, Debbie gets the strongest goose bumps run through her body. She twists her face and shakes her head because of the bitter aftertaste.

"That’s a good girl, Debbie. You’re so very talented at this! I’m so lucky to have been your first. Just... wow!" – I said, petting her head. - "Now, the final lesson of the day is: always finish the job, girls. In other words, you never, ever leave your boyfriend dirty after you two have messed around." – I said pointing down at my deflating dick, where a glob of cum was hanging from its tip. And like a proper fuck doll, Debbie quickly crawls under me and snatches the tip of my dick. She sucks the cum out and gives the whole shaft a few more tugs with her mouth before letting me go. - "What a deserving winner." - I casually say, and the three other girls finally realize they lost, frowning at the discovery.

"Now don’t be sad, girls! Just because Debbie won today doesn't mean you still don’t have a shot! Think of this as… the Olympics. Today was a bad day, but tomorrow you can still get first prize! It’s still the qualifying!"

They all look at me confused now. - "So I didn't pass math?!" - Debbie asks me in a slightly hoarse voice from the pounding she just endured.

"Not yet, Debbie, but you’re ahead of the competition! The more points you get, the better your chances of winning in the end."

"Winning? But I thought I just won!" - She continues to push.

"You did, yea. The first leg."

Dumbfounded, Debbie remains seated, staring at the ground like it was infinite. I felt a bit sorry for her, but I was exhausted. I still had to take a break and go over everything. Was it all real?

"Now go home, get some rest, girls. I’ll see you here tomorrow for the second day of the Math Olympics!" – Those beauties were so comfortable around me now they all just burst into laugh as I made that ridiculous name up. Except for Debbie, who was sure she'd passed math. As they left my office I had each of them kiss my flaccid cock goodbye. It was now time to start planning for tomorrow…
