Cedric had been told that one of the best perks of being a prefect was the use of the special bathroom. And on his first day as a prefect, he wasted no time taking advantage of his privileges: as soon as he had seen the new students to the Hufflepuff Common Room, he ran to his dorm and announced to his friends that he was going to take a bath.

He took the stairs to the fifth floor and counted the fourth door to the left of the statue of Boris the Bewildered. He said the password out loud and held his breath, waiting for the door to open.

It did, noiselessly. Cedric stepped inside and gasped in surprise. The place was amazing: the walls and floor were white marble and the bathtub was more like a swimming pool. He walked slowly towards it and saw it had several taps, each with a colored jewel on the handle.

Cedric turned a few of them experimentally, and was delighted to find the bath filling up with bubbles. He felt the water tentatively with his finger: the temperature was perfect. The bath was more than inviting, so he undressed quickly and stepped into it, with a happy sigh.

Sinking down into the bubbles, he leaned back, his hands clasped behind his head, the muscles rippling on his strong chest.

All that working out during the summer holidays had paid off: he knew he looked good. He brought one arm forward and scooped up some bubbles, rubbing them into his chest.

With a mischievous smile, he dabbed a handful of bubbles on his nipple. It reminded him of the cream on top of a sundae, and he rubbed it in with concentric movements.

It felt good, and Cedric repeated the gesture.

Cedric's hand moved down his body, disappearing under the bubbles. As it approached his navel, he heard a noise that sounded a lot like a girlish giggle.

Startled, he stood up in the bathtub, bubbles sliding down his belly and his legs and cried out, "Who's there?"

There was no answer, only the sound of giggling again. He turned around and saw there was a portrait of a mermaid on the wall beside him. She was covering her mouth to stifle her laughter, looking directly at his lower body. Cedric immediately shielded his crotch with his hands.

"Wait a minute! Have you been watching me?"

Looking down, he suddenly felt very uncomfortable, as his hands seemed to be getting smaller. Befuddled, he belatedly realized that his hands were still the same size, but his cock was growing – hard.

He turned around quickly, trying to hide his front from her, exposing instead his well-toned back and shapely buttocks.

She giggled again, and murmured, ‘Hmm…Pretty’. Her voice sounded strangely distant, as if it was coming from underwater.

Cedric whipped his hands round to cover his buttocks, and turned to scold the mermaid on the wall with a frown on his face. But, unfortunately, his cock was now very hard and jutting forward, which strongly diminished the effect of his angry face. He knew that he was blushing furiously, which didn't help.

"Why are you so red?" she asked in that strange-sounding voice.

Cedric turned even redder. His scowl softened, though, and he answered, "Because you're a girl – a mermaid, I mean – and I've never been…" He stopped short. At fifteen, Cedric was very good-looking, but unfortunately still a virgin. And a shy one at that: he was uncomfortable undressing even in front of his mates.

"You've never been naked in front of a girl," she said, making Cedric wonder if merpeople could be mind-readers too.

"Well, no. So what?" Cedric hated the fact that he couldn't lie.

"You're very handsome," the mermaid said, looking straight at his crotch. "And you need to do something about that." She pointed at his erection. "Do you have a girlfriend who can help you?"

Cedric didn't, of course. He had been sort of flirting with a Ravenclaw called Cho Chang, but he wouldn't consider her his girlfriend. And she certainly didn’t look the sort of girl who’d help him with his problem. "No, I don't," he answered, starting to feel annoyed. He wanted to wank, but, since the mermaid was there, he would have to go back to his room.

"So it's you and your hand, is it?"

Maybe it was the watery voice, maybe it was the way that Cedric was brought up, but he felt compelled to answer, even though he didn’t want to. He nodded sullenly and muttered, “Yeah.”

"It's much better in the water," she said.

“How do you know?” he asked, making a deliberate effort to be rude. “You’re only a portrait.”

"Oh, but I've been here for ages, and I’ve seen – and heard – quite a lot." She examined her nails. "I can help you, if you want."

Cedric asked, "Like what?"

"I can pretend you're doing it to me," she said coyly. "You know. I can make all the right sounds. So it’s not just you and your hand, but you and me as well. In a manner of speaking."

That was one of the weirdest things Cedric had ever heard, but it was oddly attractive. He slowly sank down in the water, resting his head against the tub. He closed his eyes and started stroking his cock; interestingly, it was much better than when he wanked in his bed. He stroked his penis a little faster, the soapy water serving as a lubricant. He didn't know why he hadn't done anything like this before.

"Yeah, yeah, just like that, loverboy. Harder."

He opened his eyes and stared at the mermaid; she was caressing her breasts and her lips were parted invitingly.

If only it had been possible, Cedric would have leapt out of the bathtub into the portrait, and taken the mermaid in his arms. And then he decided that she really could read minds, because she looked directly at him, smiled shyly, and blew him a kiss. He could actually feel it wafting across the bathroom towards him and landing softly on his mouth.

He rubbed himself harder, and she moaned. Cedric found he was unable to take his eyes off her, and his gaze moved down from her face to her delicate neck to her perky breasts. Obviously, as a mermaid, she must have been bare-breasted all along, but he just hadn’t noticed. They were rather nice breasts, and Cedric wondered what it would be like to have them in his mouth.

"Delicious," she said, either in answer to his thoughts or just to make the sounds that she had promised. Whatever the reason, Cedric could almost taste her skin, slightly salty and silky under his tongue, And maybe she could feel that too, because she put her head back and moaned again, her long hair spreading out over the canvas. Just when Cedric felt he couldn’t go on much longer, she said in her faint, underwater voice, "Come for me, sweetheart," and he did.

He closed his eyes at last and struggled to catch his breath. The water tickled his sensitive cock, and he mentally replayed what he had done, and how: or rather, what they had done, and how. After a while, he was able to breathe normally once more; he opened his eyes again and looked at her, a bit sheepishly. She seemed to be waiting for him to acknowledge her presence, because she waved playfully, then jumped into the painted lake behind her and disappeared under the water.

A little bit later, Cedric left the bathroom, with the strange sensation that he'd sort of lost his virginity, but not quite. He hadn't really been with a girl, or even a mermaid, but somehow it had felt uncannily like the real thing. Either way, it had been the best wank of his life, and he would certainly come back for more.

Being a prefect definitely had its benefits.
