Fleur must have her first!

“ ‘ow about you come over ‘ere and give me a good licking?” Fleur said, presenting her enormous cock to Monique. Monique crawled over to Fleur, licking her still cum stained lips, her own erection recovering fast and bouncing. She rubbed her face on Fleur’s penis, feeling the pulsating warmth emitting from it, warming her cheeks. From the base of the cock, Monique licked up, slowly, making Fleur’s cock slick and ready to be devoured. Once she reached the head, she swallowed it. Monique’s head bobbed up and down, giving Fleur the best, albeit first, head of her life. As Fleur was close to orgasm, she heard a familiar voice at the door.

“Hello…Fleur?” It was Gabrielle, Fleur’s sister. She walked in and froze when she saw what was happening. Fleur couldn’t hold it in as she came, her cum covered Monique in a matter of seconds, the smell permeating throughout the office. Before Gabrielle could run, the smell had taken a hold of her. She stood there, dazed, eyes listless.

Fleur ran up to Gabrielle and embraced her, her cock sandwiched between them. “Oh Gabi, I am so sorry. I never meant for you to be affected like zis!”

“How about like this?” Monique interrupted as she pulled them apart and stuck her new cock into Gabrielle’s mouth. It was covered in some kind of pink liquid. She started to find a pace as she fucked Gabrielle’s face, to Fleur’s dismay.

Fleur was confused, what was the pink liquid, then a look of shock ran across her face as she ran to her bag. Sure enough, there was a vial with a drop of pink liquid at the end of it. It was a bimbo potion that Harry had given her to spread through the school, but it was supposed to simply be drank, she was not sure what would happen to Gabrielle.

Monique started to pick up the pace, as she approached climax. With both hands, she grabbed Gabrille’s hair and pulled, forcing her whole cock into her mouth. Monique came like never before, her cum going straight down Gabrielle’s throat. Gabrielle closed her eyes and focused on drinking as much of the cum as she could.

The more Gabrielle drank, the more her body changed. While before she had a cute little butt, as she drank more cum, it grew. It started to resemble an ass that would be plowed to no end as it broke her panties. The more noticeable change was in her tits as they swelled up. No longer was she going to suffer being an A cup, now she could present her E cup breasts for everyone to see. As Gabrielle grew out of her clothes, she started rubbing her enlarged nipples, still drinking the endless cum that Monique was spraying, her lips expanding around it.

Once Monique was finally done with her orgasm, she pulled out of Gabrielle’s mouth. She noticed that her cock somehow had grown. No longer was it just a six inch average dick, now it had exponentially grown to over fifteen inches, along with gaining girth.

Fleur stood there shocked…not entirely sure what had happened…only knowing that if this happened, it was for the good of master.
