She eats the poppy

Hermione reluctantly opened her mouth and put the flower in. It had a bittersweet taste, like incredibly dark chocolate.

As soon as she swallowed, she felt a burning in her loins.

"The flower you just ate," The Fat Lady said, her eyes twinkling in the dark hallway, "Was known as Papaver Gaudens. Otherwise known as... The Orgasm Poppy."

Hermione's knees became weak, and she collapsed to the floor. "You'll be here for a while. A sample that size should last about an hour. Don't worry, I'll go tell Violet to distract Filch for a while. But as for anything else, you're on your own."

"No..." Hermione moaned. "Wait!" But it was too late. The Fat Lady left the portrait to go work with her friend.

Hermione tried crawling to the urn. "If I can get dressed," she thought, "It won't be so bad if someone finds me..." Every move she made heightened her arousal.

She moved one leg forward, lightly parting her pussy. A slight draft nearly made her orgasm right there, knocking her down to the ground again. As she tried over and over, she kept getting closer and closer until she came. Juices spread all over the stone floor, some soaking into her pubes again. But despite orgasming, she was still turned on.

She kept trying to get control of herself, but she couldn't do anything without still being aroused.

After another orgasm, she heard the Fat Lady's voice behind her. "This really is a marvelous show... Papaver Gaudens was always my favorite thing for a young witch to find! Oh, back in my day, it was used to make a wonderful tea that could only make you orgasm once or twice! But eating one whole? Oh, it's one of the best times you can have... I remember when me and Vi- well... Let's just say it was a fun evening!" She stopped herself before telling the whole story.

Hermione wasn't paying that much attention, she was still trying to get the robes from the urn. "Really, girl!" The Fat Lady called. "You will enjoy yourself far more if you just let it all out! You've only got another 45 minutes left!"

But Hermione didn't stop. She couldn't stop. She couldn't risk her shame being seen by anyone else tonight! Orgasm after Orgasm slowed her crawl across the hallway to the urn. She was almost at the urn, when one more explosive orgasm came, the most pleasurable one she'd had all evening. She tried to catch herself on the side of the urn, but she fell over, the urn with her. A crack echoed through the hall.

As footsteps approached, Hermione weakly tried to make her way to the portrait hole, asking the Fat Lady to open up as fast as she could.
