It was Gilpy

"Gilpy?" Hermione exclaimed.

"Please do not be mad at Gilpy, Miss..." Gilpy replied. "Gilpy admits he finds miss pretty, but Gilpy waited to see if the other elves wanted to try, miss!" He looked at the floor, somewhat guilty. "The other elves is still not trusting, you, see. They thinks miss is plotting to make them free!"

"It's... it's alright Gilpy." Hermione was somewhat relieved. If she was going to be spending the night with an elf, at least it was one that seemed to trust her somewhat.

Pansy smiled. "Well, since we're all here, Millicent, is there anything else before we get started?"

"Yes, actually." Millicent actually looked somewhat disappointed. "I wanted to make you go for 12 hours, but the other elves said we could only borrow this one," she pointed at Gilpy, not even bothering to use his name, "until 5 AM."

Hermione looked at the clock on the mantle. It was just after 8, so she'd be with the elf for 9 hours. Still, she thought. He was small. He would probably be tired out quickly. Oh, how wrong she was...

Gilpy began to remove his tea towel toga. His penis, although looking about average for a house-elf, was rather small compared to the ones Hermione had caught glimpses of in the prefect's bathroom before. She actually found it a little cute.

As Hermione laid back on the bed and Gilpy began to climb on top, Daphne interrupted them. "Hold on just a second, you two!" She pulled out a small jar from her pocket, coated her finger with some sort of jelly, and then rubbed her finger inside Hermione's pussy.

"What-" Hermione exclaimed, as it was rather cold.

"Don't worry," Daphne said happily. "This stuff doesn't have side effects. It's just a lubricant. Besides..." She got a somewhat wicked look in her eye. "You won't be needing it soon."

Hermione didn't have time to question as Gilpy took a hold of Hermione's legs and began to gently stroke her labia with his little penis.

Pleasure immediately shot through her body. She moaned as she looked down at her groin. She could see he hadn't even penetrated her yet, and she was so close to cumming already!

The Slytherins snickered. "Of course a slag like you would want to fuck a house-elf!" Millicent giggled.

As Hermione felt ecstasy course through her, she used what concentration she had to turn to the Slytherins. "W-what do you mean?"

"Oh, come now!" Daphne chided. "You know why house-elves love obeying us!"

Hermione bit her lip, trying to not make her only response be more moans of sexual joy. Despite 4 years of heading S.P.E.W., she actually didn't know.

"You don't?!" Pansy exclaimed in disbelief. "Well, we're in for a better show than ever! House-elf genitals get stimulated when they obey an order or punish themselves for failure. They never let themselves cum in front of their masters unless their masters allow it, but since we asked an elf to fuck you, it still counts! And if their bits happen to be touching the bits of a witch or wizard," Pansy's tone was getting more and more excited, just as Hermione was getting, "They feel that same stimulation!"

At that moment, Gilpy's 4-inch cock slipped inside Hermione. Immediately Hermione's eyes bulged as she had the most pleasurable orgasm she'd ever had in her life. But Gilpy kept going, and Hermione felt like she needed no break.

"What's more, house-elves don't have a refractory period," Millicent concluded. "So you picked a partner that will make you excited. All. Night. Long."

Hermione didn't question it. She just felt the absolute bliss of Gilpy's penis rubbing her insides.

They changed positions all night, at least the ones Hermione could do with the lead still tied to the bed, their juices continuously making sure their genitals could stand being in use for so long.

Hermione was too preoccupied to notice, but the Slytherins were reacting in their usual way. Pansy looked like she was thoroughly enjoying the show of her school rival being fucked by a non-human right in front of her. Millicent had watched in delight after a while, but slowly began to get bored and started to fall asleep. Daphne, unbeknownst to anyone in the room, had pulled her arm inside her own robe and was starting to touch herself, hoping against hope that nobody would notice that she was getting off to this.

At around 4:57 the following morning, Gilpy came inside Hermione again while they were in doggy style. While Hermione wanted to go again, Gilpy had to refuse.

"There is no time, miss... Gilpy will be having to go back to the kitchens soon..." After the clock struck 5, he put his tea towel back on, yawning. He also grabbed the robe in the corner. "Gilpy will bring miss some food... Miss needs some rest."

Hermione hated to admit it, but she was extremely tired. The Slytherin girls took Gilpy's departure as their queue to go. "A-a-alright, mudblood," Millicent struggled to get out. Millicent touched the lead to make it disappear, freeing Hermione from the bed. "You passed the task. Congrats. Pansy... you wanna talk number three now?"

Pansy shook her head. "Bed first... We can talk about it later..." The Slytherins stumbled out of the room. At least their common room was close by, they'd get to sleep soon. Hermione, on the other hand, would have to walk all the way up to the Gryffindor common room if she wanted to get to her own bed.

Gilpy appeared again with a tray of sandwiches and pumpkin juice and the silken blanket he had conjured for her before. "Miss can sleep here," he said, smiling up at Hermione. "Gilpy will put the furniture back when Miss has left the room!" He then left the room again, leaving Hermione alone.

Hermione took one of the sandwiches and ate it. It was really good... Both the sandwich and the sex she had, but she knew she couldn't do the latter again... She realized that, as wonderful as it was, she could get seriously addicted to it.

After eating and drinking some juice (she hadn't realized how dehydrated she had become), she took the blanket and went to the bed. There were still wet spots from both sweat and cum, but she found she didn't care as her eyes closed before falling asleep in seconds.
