Let Brie work for it

Looking down at Brie's passive form, I realized just how much I'd dominated this encounter. This whole thing was supposed to be about her helping me cum, but it was more like me using her to cum. I decided to put her on top for the grand finale.

I pulled Brie off the desk and patted her face until some life came back to her dazed eyes, then turned to the crowd;

"Brie's been such a good sport so far; how about we let her ride me cowgirl-style for the grand finale? You wanna see that?"

The crowd cheered the affirmative, so I took Brie's place on the desk and told her to take the rest of that beautiful dress off and mount me. Finally naked, she climbed onto the desk again and straddled me, lining up my cock with her surprisingly wet hole. She must've been enjoying this more than she let on.

"No, no," I stopped her before she got my head inside. "Turn around; I want your adoring public to see your face when I creampie you."

Brie's eyes opened wide at the word "creampie," like she was expecting me to pull out for some reason, but she turned around anyway before impaling herself on my dick. Her body betrayed her immediately; she let out an involuntary moan of pleasure as I stretched her out. I'd fucked actual virgins whose pussies weren't this tight. Maybe that joke about her boyfriend's dick was truer than I thought...

I fought every urge to thrust into that marvelous (ha!) cunt. Brie was clearly starting to get off in spite of herself, and I wanted her to put in some effort for once. She got into a rhythm almost immediately, working her muscular legs to bounce along my entire length. Her breath quickened as she rode faster and faster, with more and more whimpers slipping in.

"Share with the class," I said, aping Brie's earlier condescension and slapping her tender, bruised ass. "Tell the people how you feel."

"Th-this..." she gasped, "this feels SO GOOD! I've never had one this BIG before... I-I didn't know what I was missing! My... my boyfriend... I love him, but-- OH! He always has t-to eat me out at the e-end for me to f--f--FINish... Th-this is the first dick I've... I've ever had that... that's got me this CLOSE this FAST! Oh, OH, OH GOOODDD!!!"

I grabbed Brie's hips and pulled her down, bottoming out as she came. The walls of her pussy teased out my own orgasm, and I pumped a massive load into Brie Larson's quivering womb. I had been cumming more and more since my diagnosis, but this was something else entirely; I literally filled her up with cum until the pressure broke the seal and it started leaking down around the sides of my shaft.

We stay perfectly still for a moment in quiet contentment as I let Brie enjoy the feeling of being completely stuffed. After a while, I sat up and wrapped my arms around her waist, doing my best to keep her pussy plugged with my deflating dick, and rested my chin lovingly on her shoulder.

"Thank you so much, Brie," I whispered. "It's very brave of you to let an EDP knock you up."

"I-I'm on birth control," Brie protested, clearly worried.

"Oh, didn't they tell you? My sperm count is so high that nothing short of a hysterectomy can stop it from fertilizing all the eggs you have, whether you're ovulating or not."

Brie fought her way out of my grip and off of my dick, spilling some of my load as soon as her opening was unblocked. She squatted immediately, flexing her kegels or something to push as much of my seed as she could out of her fertile cunt, then scrambled for a bottle of water hidden under her desk and lay on her back to try and rinse out the remaining jizz.

I had no idea if that would work, or even if it was safe, but it sure was hilarious. The audience agreed, laughing harder at this ludicrous display than they had at any joke Brie had told that night. All that water gave me an idea, too.

"And, as a brief public service announcement for all the guys out there, EDP or otherwise, it's important to flush the system after an orgasm. You've gotta make sure there're no stragglers in there that could cause a UTI. The easiest way to do that, of course, is with urine!"

I stood on the desk and aimed my flaccid dick squarely at Brie's face, releasing a solid stream of acrid piss all over the Academy Award winner. Her hair, a little sweaty from the amazing sex we just had, wound up soaked and matted, and her face glistened with a thin layer of my pee. I jump down and grabbed Brie by the shoulders, dragging her right in front of a camera to give the viewers at home a close-up view of my beautiful artwork.

"Ladies and gentleman, let's hear it again for this freshly ruined slut and my newest baby mama, Brie Larson!"
