On Valentine's Day, Jeff woke up to find one of Hogwart's general owls perched on the bottom of his bed. He rubbed his eyes sleepily and crawled over to see what it had brought.

Once he had released the owl, he saw it had delivered a piece of parchment labelled "Jeff" in Nick's sweeping scrawl and a large bouquet of bright yellow daisies. Jeff smiled brightly to himself. He remembered my favourite flower! He thought.

Hopefully Squirt will have delivered my present to him by now, too. Jeff had also snuck out of the Hufflepuff tunnels very early that morning to send Squirt on a covert mission to the Durmstrang ship, before heading back to bed. I wonder how close we came to bumping into each other in the owlery!

He had sent Nick a note asking if he remembered their first date and had gift wrapped a bag of his boyfriends's favourite, lemon sherbets, together with a chocolate frog and a Fizzing Whizzbee. He had ordered them by owl from Honeyduke's as a surprise.

Cedric was awake by now, smiling as he read his valentine message from Cho, before opening the chocolates she had sent him.

"Hey Jeff! Those flowers are cool, let me guess, from Nick?" Jeff smiled widely, nodding. "Of course, who else? How did I get so lucky, Ced?"

Cedric smiled back. "Well coming from your best friend, I say you deserve it. Nick too. I'm happy for you guys." he laughed. "Okay, enough sappiness, lets get showered and dressed and go meet our other halves for breakfast."

"Sure, but you mean after breakfast, still house seating remember?" He rolled his eyes.

When Jeff sat down at his place on the Hufflepuff table, he found a brightly coloured, heart-shaped piece of rock, probably from Honeyduke's, in front of him. Nick. He thought, smiling softly.

He read the words running through the hard sweet, written in clear red sugary mixture "Be mine, I'm yours" written through it. Little did he know that Peeves had stolen it from the Weasley twins the day before, after seeing what it had done to them.

Just as Jeff popped it into his mouth and started to suck, Peeves gusted along the table, yelling at the blond Hufflepuff as he floated past, "Hahaha! I bet you thought that was from your lover boy!" He sniggered, and Jeff's smile was replaced by a look of confusion, then panic.

George Weasley looked up from the Gryffindor table, realising too late what was going on. In vain he started running to Jeff, shouting, "Jeff! No! Don't eat it!"

When he reached the Hufflepuff, the expression of shock on the blond's face showed he was indeed too late. George watched the horrified expression cross Jeff's features, before he asked with a smirk. "Nick, I presume?"

"Yes! How did I get here? Why am I in Jeff's clothes? What's going on?"

Cedric looked confused, next to him. "Jeff? What's wrong?" He asked.

Nick's eyes widened as he started touching his face, before reaching up to find hair that was more than a few millimetres long. Long fine, blond hair that he could even see by rolling his eyes up to his fringe. Oh my god. I'm Jeff!

George interrupted his thoughts. "I tried to tell Jeff not to eat that, Peeves gave him a body swapping gob stopper I got from Zonko's, he probably thought it was from you. It's swaps your body with the person you love the most, within a certain range, of course.

Fred ate one yesterday and we swapped, but nobody noticed. Except Peeves and he nicked the last one. Don't worry, you'll be back to your normal self..." he broke into laughter at his own pun, "by dinner time."

Meanwhile, over at the Durmstrang table, where Nick had only seconds ago been chatting with Viktor, Jeff was panicking as he stared wide-eyed at the Bulgarian in confusion.

"Viktor? What am I doing at your table?"

Viktor answered but Jeff wasn't listening. He glanced down and saw he was dressed in the now familiar chocolate brown Durmstrang uniform. Shaking his head in utter disbelief, he gingerly put his hand up, feeling stubble and gasped in horror. "Who the fuck shaved my head?!"

Once Jeff had calmed down after Fred, George and someone in his own body talking to him, claiming to be Nick, explained the situation, he began to relax. A bit. Well, about as much as he could given the weird situation they were in.

Nick in Jeff's body leant forwards to kiss him, before he frowned, backing away saying, "Oh my god, no, that's too weird! It's like I'm kissing myself. I know you find me attractive, but I'm not my type!" The two boys both laughed hysterically in agreement.

Jeff thought for a moment. "Okay, but maybe we could shut our eyes? Ugh, no, that's still too weird. Lets just be friends for the day, yeah?"

Nick looked down at Jeff's body, suddenly wanting to touch. "Maybe we should practice quidditch, then I can take this damn fine body for a shower?" He wiggled his eyebrows suggestively.

Jeff put his best bitch-please look on, which looked really funny on Nick's face. "Really? Well maybe I'll just have a little fun with your body right here!"

He started wandering his hands all over Nick's gorgeous body, getting a bit sidetracked when smoothing over his abs and lower before Nick choked out, "Enough! Everyone will think I'm an exhibitionist - stop touching!"

Jeff pouted, reluctantly removing his palm from his, or really Nick's, crotch.

"Okay, well we ought to stick together while we're swapped to avoid any problems, and we can't go to classes like this. So what about quidditch, the pitch should be free as it's a Tuesday, then lunch and then swimming, by which time we will be back to our normal bodies, hopefully?

Then perhaps your idea of a shower will be a good idea." Jeff winked, suggestively.

Nick nodded. "Okay, that sounds good, but don't wink at me from my body, it feels like I'm practicing sexy moves in the mirror!"

After breakfast, the boys headed to the quidditch pitch to play in their robes, since neither of them wanted to risk being soaked in vinegar at Hufflepuff's entrance or Jeff being accused of trying to go on board the Durmstrang ship without permission.

Staying together helped and by the time they were in the swimming pool late in the afternoon, they had almost got used to it. Jeff felt strange teaching his own body how to swim, however, but he didn't have much choice.

Just as Jeff was correcting Nick's arm stroke, he felt a strange sensation like dizziness pass over him, before he was suddenly swimming in the water, apparently being taught by Nick. He stood up quickly and flung his arms round Nick's neck, kissing him hungrily.

"Mmmf. I've missed this, so much!" Nick would have replied in agreement, but he was too busy sliding his tongue around his boyfriend's.

He grabbed Jeff's legs, lifting them easily to wrap around him in the water, before settling his hands on the blond's ass as he started to wade out of the pool, heading for the showers.

They kissed on and on, water from the shower seeping between their lips, pounding on their bare shoulders and down their backs, snaking down their legs and away down the drain. Jeff dropped his legs to stand, hooking his thumbs in his shorts and removing them, before taking Nick's off too.

Jeff broke the kiss to run to his robes, fishing out a small bottle of lube and a condom before hurrying back to his aroused and panting, dark-eyed boyfriend. He kissed him firmly before passing the lube to Nick, looking at him seductively as he turned his back to him, leaning against the wall.

Nick moaned in anticipation, licking his lips at the sight of the blond's perfect naked, wet, backside in front of him as he slicked up his fingers. He bent forward to kiss and suck at Jeff's shoulder blade and neck as he worked him open quickly.

Once Jeff was ready, he quickly grabbed the condom, rolling it on and slicking himself up before standing behind Jeff, holding his hips as the blond leant his hands and forehead on the wall, spreading his legs wider and offering his ass backwards towards Nick as an invitation which the Durmstrang boy took willingly.

Nick thrust in and Jeff bit his lip, a moan of pleasure escaping him as the brunet started to work up a relentless rhythm. Nick watched the water snaking down Jeff's back as his boyfriend panted and moaned, grasping at the wall to remain standing.

Over and over Nick pounded in, before Jeff suddenly yelled, his ass muscles clamping around Nick, who came hard too. He slipped out and Jeff turned round, bringing Nick in close, wrapping his arms around him before they slid to the floor to recover.

"Happy Valentine's Day!" Nick whispered, out of breath. Jeff smiled, dropping a kiss onto his boyfriend's head. "I love you."

"Love you too."
