A nice calm before the incoming storm

With Moaning Myrtle still at the Ministry with the other ghosts, Hermione was able to truly enjoy this bath of hers.

The flow of the water over her curves, the warmth compared to the chill of the castle, it all felt so wonderful!

Hermione looked up and saw the portrait of the mermaid on the wall. She was gazing down upon Hermione, lazily watching her.

Hermione then realized that this mermaid never left her portrait... Nor did it ever speak.

Hermione began to have dirty thoughts as she was trying to get clean. She swam over to her bag, dried her hands, and took her wand and the Marauder's Map.

"I solemnly swear that I am up to no good!", Hermione giggled.

At once, the map showed Hogwarts and the locations of its inhabitants. The usual people could be seen in the hospital wing, their names overlapping each other in such a tight space. Hagrid was in the forbidden forest. And the Slytherins...

Hermione saw that the three Slytherins were in their common room.

Satisfied, Hermione placed her wand tip on the map. "Mischief managed!" She beamed.

She made her way underneath the portrait of the mermaid. The mermaid was eyeing Hermione, unsure of what was about to happen.

Hermione then laid on the tile floor, and began to touch herself.

The mermaid stared in awe. She had seen countless students naked, fooling around a little under the water, but none that would so brazenly show themselves like this to her.

Hermione cupped her breast as she continued to play with her labia. The mermaid smiled. Evidently, she was rather enjoying the show.

The sight of her reaction only served to arouse Hermione further as she began to play with her clitoris, opting to not play with her hole this time simply for the fun of it!

The mermaid moved her long hair, revealing her own substantial breasts.

"Of course... " Hermione said. "Even the portrait has larger breasts than me..."

The mermaid giggled silently as she fondled her own chest, urging Hermione on.

In a manner of moments, Hermione came yet again, her juices mixing with the water that was dripping from her naked body.

Hermione turned around and got back into the bath to clean herself off before reemerging, using her wand to clean the floor around the bath as it drained.

"I..." Hermione said. "Might have to come back for more... If you're up for it." The mermaid winked. This had been the most fun she'd had in ages!

Hermione picked up a towel and dried herself off, making sure to give the mermaid a show.

She then turned to her bag and grabbed her own robe from the pile and put it on. She looked at the clock. She had been here longer than she thought, as it was almost time for dinner! Time sure did fly as she was having fun...

In the middle of dinner, Daphne demanded another wardrobe check, to which Hermione obeyed. The Slytherins looked at each other, somewhat confused.

"Are you just wearing more clothes before seeing us?" Daphne asked, "Or are you just stripping naked between meals?!"

"If you must know," Hermione answered stiffly, "I had a bath this afternoon." She took a bite of her baked potato.

"Well." Pansy began. "I suppose we might just have to stick around the castle more after tonight's task. Remember, be there, or your pictures will be everywhere!"

The three Slytherins retreated to their common room.

Hermione made her way up to Gryffindor tower.

"Well... I suppose you'll be using the regular password this time?" The Fat Lady said, somewhat dejected that Hermione was coming in clothed.

"Yes. Abstinence!" The portrait swung open as Hermione chose to get a couple of hours' sleep before she'd have to perform the first of the Slytherin's dares...
