Potion

“What kind of potions do you have in there?” Dudley asked.

“Well…” Malfoy searched through her satchel, “Ah, this is a good one!” She revealed a white potion bottle. The sloshed it around and it reminded Dudley of milk for some reason. “This one is something Cho made herself. She’s a really good fuck.” Malfoy walked over to Julie and flipped her over onto her back. She ripped open her blouse and tore away her bra. “You won’t be needing those.” She said as she pinched her nose, causing her to open her mouth and **** the potion down her throat. Once she was done, she threw the bottle to the side. “Lucky for you, the potion will negate my cock’s magic. So you won’t grow one of these.” Malfoy explained as she slammed her cock into Julie. “On the other hand, your breasts and mind won’t be as lucky.” She made quick work at cumming, already being so close. As she released the torrent into Julie’s pussy, the effects of the potion were made clear. Julie’s C cup breasts started to grow, rising from her chest like dough. She could feel the milk inside them fill them up. Soon, her nipples darkened as they released their first spray of cum. Julie’s eyes rolled, she could feel her intelligence draining away with each drop. In no time, Julie had covered herself in her own milk.

Suddenly, the door opened and in walked an attractive blonde. “Pardon me Miss Mathers bu-“ she looked at the scene before her. Sarah, was still rubbing her cum filled belly, and Julie on the ground being fucked by someone, still spraying small amounts of milk now.

“Stupefy!” Malfoy yelled from her position, freezing the mystery woman in place. She pulled her enormous cock out of Julie and saw the blonde’s eyes go wide. She stood and walked over to the mystery blonde. “Hm…Piggy, who’s this?”

“She’s the principal…just started here this year. Her name is Jackie Cox.”

Malfoy looked to Dudley, “You can’t be fucking serious.” Dudley shrugged. Malfoy turned back to Jackie, still stunned. “Alright, in just a bit I’m going to release you. You’ll have one of two choices. I have a proposition for you. My master wants your senior students to go on a school trip. Say it’s a uni visit or something. They won’t come back from this one though. Don’t worry, they won’t die.” Malfoy could see her looking at her former teachers. Both of them moaned, feeling up their new bodies. “If you don’t agree, or try to pull something, well…let’s hope your employees are clear examples of what we can do.” Malfoy released her from the spell. She hefted one of her breasts, waiting for the principal’s answer.
