September

Ginny ascended the owlery tower and stepped out onto the straw-laden floor. Beams of sunlight were streaming through the holes in the walls, and a gentle draught blew around her. Before she had even had chance to look around for him, Pig had descended from one of the ledges and landed on her shoulder, squeaking excitedly. She smiled to herself as she considered whether Ron allowing Pig to stay with her for her final year at Hogwarts was a generous gift from him, or whether she was actually doing him a favour by giving him a break from the little terror.

She pulled out a small piece of parchment and her quill, and leaned against the wall to write a brief letter:

H,

Hagrid's, 7pm Friday. Bring cloak.

G

She finished writing the message, rolled up the scroll and tied it to Pig's feet before he obediently jumped through the owlery window, plummeting several feet before managing to gain some momentum, as was his usual practice, no matter how short she made her letters.

Pig returned at breakfast the next day, knocking over Ginny's orange juice and stepping in her scrambled eggs in his enthusiasm to complete his delivery.

"Thanks Pig," Ginny said as she unfurled the sodden piece of parchment.

G,

See you then. Will visit Hagrid too.

H

She bit her lip, trying to hide her smile at the thought of her plan coming together.

The week dragged on until seven o'clock on Friday eventually rolled around, and Ginny jogged briskly down the grassy bank towards Hagrid's hut, skidding to a halt in front of the pumpkin patch.

"How was Hagrid?" Ginny asked the seemingly open air in front of her where she instinctively knew Harry was standing, hidden in his cloak.

"He seemed well," Harry said, laughing at Ginny's intuition as he fell into step beside her and they began to walk up the hill to the castle together, "how have your first few weeks back here been?"

"Not bad really," she replied, "excited to get back to quidditch though," she said, miming throwing the quaffle as Harry laughed beside her, "and missing you of course."

"I've been missing you too," Harry said, and as he spoke Ginny could feel his arm loop around her waist, and she felt a thrill as his hand wandered lower and lower as they drew nearer to the castle.

"How are things at your new house?" Ginny asked.

"They're good," Harry replied, and Ginny could hear the smile in his voice, "there's so much I can't wait to show you once you get the chance to visit".

"I can't wait either," she responded with a smile.

Once they reached the main entrance they stopped talking, and Ginny walked confidently up the stone steps, crossed the hall, and mounted the marble staircase on the far right hand side, with Harry following invisibly a few steps behind her. He tailed her all the way up to the fifth floor where she pulled up in front of a nondescript door just beyond a statue of Boris the Bewildered.

"Wait, you didn't become a prefect without telling me did you?" Harry asked, recognising this as the door to the prefects' bathroom.

"Merlin's beard, no! I forced Hermione to tell me the password and it seems they just never change it," she replied with a shrug. "I like coming here for a rest after quidditch matches sometimes. Pine fresh," she said, turning to face the door, which clicked open at her words.

Ginny led the way through, and the pair entered the large, open room where whitewashed walls and a marble floor surrounded a sunken pit in the centre. At one end of the pit was a series of steps leading down into it, and at the other were dozens of gold taps which glistened in the soft light of the candle-filled chandelier.

As soon as the door closed behind them Harry ripped off the invisibility cloak, then Ginny felt his hands work their way around her waist again as he turned her around and their eyes locked.

"I've really missed you," he whispered.

"I've really missed you too," she replied before his lips came down to meet hers, stopping any further possibility of conversation in its tracks.

Her hands found the fastening of the black cloak around his neck and pulled it apart, sliding the fabric down from his shoulders, a move that he reciprocated with her cloak. Their hands ran over each other's upper bodies and Ginny snaked hers inside Harry's jumper to feel the chest and arms which had lost none of the definition that years of quidditch had given them.

"Shall we run a bath?" she suggested.

"Sure," Harry replied breathlessly.

Ginny walked down the long side of the pit in the floor to the golden taps at the far side and turned on a selection. The bath filled in no time, the surface shimmering with glittery rose-golden bubbles.

"Hop in," she called to Harry, then watched as he removed his shirt, trousers, and underwear (semi-erection noted) and lowered himself down the steps at the other end of the pool into the water.

As she stood up from the taps the figure of the mermaid in the golden-framed portrait on the wall caught her eye.

"She's about to see more than she bargained for," Ginny mused aloud.

"Hmm, I doubt we're the first," Harry replied.

"No, but we'll be the best," Ginny responded boldly, and without a second thought she pulled off her remaining clothes and jumped into the water, before swimming out to meet Harry in the middle of the bath.

She couldn't reach the bottom here but felt safe and secure as she wrapped her legs around Harry, and they leaned in for their lips to meet again, bodies pressed firmly together. She could feel Harry rising beneath her, like the steam and bubbles surrounding them, and she was flushed with a warmth which was not entirely due to the hot water.

They continued kissing fervently, savouring the taste of each other's lips, even more potent after spending time apart, and Ginny wound her hands around Harry's neck and through his hair, pulling him to her as tightly as she could.

Ginny had not realised that they were drifting towards the edge of the pool until her back bumped against the marble. Harry lifted her out of the water so that she was sitting on the edge of the bath and encouraged her to recline until she was laying down on the heated surface, with her toes still trailing through the bubbles. He grabbed her thighs, now slick with soap, parted them, and placed them over his shoulders. His fingertips touched the outside of her folds, and before she could form another thought his mouth was upon her.

There was sucking, nibbling, licking, kissing, and actions she couldn't even name, but whatever he was doing it was magic. She felt electric, alight, high. In no time at all she was panting and gasping at the blissful torture, writhing on the marble. Ginny felt Harry push one finger inside her as his tongue continued to dart around her clitoris. She could no longer tell what was soapy bathwater and what was her own moisture, but she didn't need that to tell her that she was turned on.

"More," she moaned, and Harry obediently inserted another finger alongside the first, then started to move them inside her, gently at first but soon gaining momentum. It wasn't long before her moans could be heard echoing around the chamber and her toes curled over as the muscles of her pelvis clenched and released with the rhythm of her climax.

Afterwards, her hands wandered lazily through Harry's hair as she took several deep breaths, and he affectionately kissed the inside of her thigh and ran his hands over the curves of her hips.

"Now I'll drive," Ginny said once she had regained her composure, as she slid into the water beside Harry again. She reached down and took hold of his erection, now standing full and proud, and moved her hand up and down it, tasting herself and the perfumes from the bath on his lips as she resumed the kiss.

After a few minutes of this, and becoming tired of treading water, Ginny pulled herself out of the bath again.

"Come here," she said to Harry, pointing to the floor beside her, "lay down."

Harry did as he was told, obedient as ever to the woman who held so much power over him.

Ginny pecked him on the lips as he manoeuvred himself to lay down on the floor, and once he was in position she crouched over him so that their pelvises aligned, then lowered her body onto his. She felt whole again as he filled her up once more, like a part of her she didn't realise had been missing for the last month had finally returned, and her breath caught in her throat.

Once she had adjusted to the stretching fullness that she was experiencing she started to rock back and forth slowly, letting her clitoris glide against Harry's soapy body, and relishing the throbbing sensations that it was giving her.

"God I've missed you, Harry," she said as she picked up speed and started slowly and deliberately clenching and releasing the muscles of her pelvic floor around his engorged penis.

"Woah, woah, I'm not going to last long if you keep doing that," Harry said, placing his hands on her hips again to hold her still as he took several deep breaths.

"Turn around," he said, pushing at her waist as he slid out of her and encouraged her to face away from him. She felt his movements fold her over so that she was on her hands and knees and heard him shuffle up behind her. Before she knew it he was inside her again, moving in and out slowly at first. She couldn't remember them ever doing it like this before, but she was enjoying how animalistic it felt and couldn't stop herself rocking back and forth so that their wet bodies slapped together each time they met.

She could already feel her inner tension building when Harry unexpectedly reached around and started circling her clitoris with his fingers, and she knew this was a winning combination.

"Yes, yes yes, just like that," she groaned, "I am so close, don't stop, don't stop, don't stop."

Harry did as he was told and within a few more thrusts Ginny exploded into another orgasm and heard Harry follow suit soon after as the clenches of her walls threw him into release too.

"We're getting so good at that," she said as they lay down next to each other afterwards.

"I know right," he replied, before offering his hand to her for a high-five, which Ginny laughed aloud at but reciprocated. Before she could pull her hand away again he curled his fingers around hers and pulled them to his lips, kissing the back of her hand.

"Shall we rinse off?" she asked, and Harry nodded, then they both lowered themselves back into the bath.

With a smile she noticed that the mermaid in the window had rolled over to face away from them.

"Told you it might be too much for her!"
