Lunch before heading up to the common room

Hermione went down to the great hall and as she filled her plate with meat and potato pie, the Slytherins walked in. As soon as they sat town, Pansy began to talk in a business-like tone.

"Listen, Granger. Me and the others have been talking. Starting tomorrow, we want you to only eat at the same time as us. That means you show up here at the same times we do and you leave at the same time as we do."

Hermione looked up, trying to look dignified. "And if I refuse?"

"Then we spread the pictures of you cumming in the seventh-floor corridor, you nonce!" Millicent growled.

"Aaand!" Daphne interjected with a smirk, "If we have to go looking for you, we get to play with you!" Well... That was a pretty compelling argument, Hermione had to admit. After she was told the exact times she was expected to be in the great hall, all the girls returned to their lunches.

Hermione finished first and got up. "Wardrobe check!" Daphne demanded. Somewhat annoyed, Hermione didn't even turn around when she lifted up her robes, exposing her bare backside to the Slytherins, much to their laughter. Hermione heard them whispering as she left the great hall. No doubt they were discussing how they were planning to convince Malfoy to give them polyjuice potion.

Hermione briefly considered going to Hagrid to write a letter to Harry to see if he could intercept Draco, but she decided against it. Not only would the delay between parties be an issue, but she also knew that Harry would question how Hagrid knew that the Slytherins might be getting the potion from Draco, and Hagrid wasn't great at lying.

Being exhausted from practicing wandless magic all day, Hermione headed to the common room for a nap before she returned to practice. She was so engulfed in her own thoughts that she didn't notice someone was tailing her as she went up the stairs.

It was around the 6th floor when Hermione, who was so focused on thoughts about wandless magic and her predicament, suddenly sank. When she got her bearings, she realized that she had gotten her leg stuck in the trick staircase with the disappearing step.

Her legs parted with nothing between her and the stair, she felt the carpet rub against her bald pussy briefly. This was bad. Most students wouldn't be able to pull themselves out. She could try to use magic, as she had used yesterday when she got caught on a lamp, but she knew that one wrong move would send her hurtling down the staircase, likely to break a limb or worse. As she struggled, she didn't notice that the person tailing her had come up.

"Need help, Granger?"

Hermione looked up to see Daphne Greengrass, arms folded, somewhat enjoying Hermione's current state. "I-um..." Hermione didn't know what to say. She knew she couldn't entirely trust Daphne, but she knew she couldn't get out safely without help.

"Tell you what, Granger. If you agree to let me play with you whenever I see you naked, I'll help you up now."

"W-what!" Hermione spluttered. "Why would I ever agree to that?!"

"Because, Granger... Aside from your only other option being waiting for a house-elf to help you up, I know you love it." Daphne crouched down to be near Hermione's face. "I can tell... You get excited every time you're seen naked. You want to be played with. You want us to do this!"

Hermione's face flushed. It was true she had wanted it... Ever since she had agreed to the tasks, Dumbledore's spell over the castle grounds had ensured that all of her desires would come true. But still, she had to make sure of something.

"It's... only until the end of the Easter holidays, right?" She stammered. "As in, after term starts, you won't do this again?"

Daphne's grin grew wide. "Only when it's just you, me, Pansy, and Millicent. What do you say?"

Well... It was better than nothing. "A-alright..." Hermione consented.

"Very well! Now let's get you up!" Daphne began to tug on the shoulders of Hermione's robe.

"W-wait!" Hermione exclaimed, suddenly worried about exactly what Daphne's pretense for this was.

"Don't fret, Granger! I'll pull you out by the robe and you'll be out in no time! Just keep your arms down unless you want some fun now!"

Hermione did her best to keep her arms down, but the constant tugging on the robe was pulling her arms up further and further until with a great wooshing sound, the robe came off Hermione's body entirely.

"Oops!" Daphne giggled as she threw the robe behind her. "Well, let's get you out of here!"

Daphne moved her hands down to the leg that was stuck, ostensibly to move it, but she instead grabbed Hermione's groin. Daphne made half-hearted attempts to pull Hermione up, one hand under Hermione's thigh and the other hand right on her labia, one finger inside of Hermione, before dropping her. "Oh, it's getting slippery!" Daphne teased.

After pretending to help for some time, Hermione came all over Daphne's hands. "Ooh, Granger! Look's like you enjoy getting help!" Daphne snickered. "Here, how about I just lift you by your arms instead! Just try to keep them down this time!"

She wiped her wet hand on Hermione's back before finally lifting Hermione up. "Well... That was fun! Try to avoid that step from now on, though, unless you want to do this again!" Daphne walked down the stairs with a smirk on her face. Hermione turned to where Daphne had thrown the robe, but she knew it was too late. All that remained in that corner was her bag.

Hermione began to panic now. The only clothes she had left, or at least the only ones that the Slytherins would allow her to wear, were one more borrowed robe and the robe that was too small.

She quickly threw on the last borrowed robe from her bag and went up to the common room to sleep for a couple of hours.
