------------------------

Justin anxiously searched for words. Alex knew something wasn't right with Dean, and she suspected Justin had something to do with it. Knowing that he couldn't lie to her, Justin decided that the easiest route was to just face the music right now.

"Alex please, you have to understand... you may prefer to ignore important things, but you have no idea how hard it has been for me to just pretend nothing happened," Justin attempted to explain. "What he tried to do was completely despicable and unacceptable, and the thought of him just getting on with his life without having to answer for anything was absolute torture for me."

"Justin. What. Did. You. Do?!" Alex demanded.

"Don't kill me, OK? What I did was very shocking and wrong, so I don't want you to judge my character based on this..." Justin pleaded, taking a deep breath. "... I put a curse on him that would temporarily make his balls disappear." He shut his eyes and immediately cringed, bracing himself for whatever might happen next.

Unexpectedly, Alex's raucous laughter echoed throughout the room.

"That…" she said, gasping between her laughs, "is pretty good…! Hahahah…"

"Wait, so you're not mad? I performed a completely unforgivable hex on a mortal, and you're…amused?"

"I'm more surprised than anything else, Justin," Alex chuckled, her laughter dying down. "I wouldn't expect you to do something so nasty for me. But I gotta admit, I'm touched." Alex gave her brother a wide grin.

"Alex, you know I would do anything for you," Justin said, sighing heavily. "Wow…what a relief."

"Ah-ah-ah! Don't think you got off that easily. You shall be punished later," Alex smirked. "AND you have to put Dean back to normal. It may be funny, but it's still really weird…"

"Yeah, I know it is… I'm sorry, Alex. I swear, I did not mean to interfere with your life. I've just never felt so strongly about anything before…" Justin said sincerely. He reached forward and held her hand.

"It's OK, Justin. I appreciate the thought behind it," she said, squeezing his hand. "Now seriously, please… can we undo that spell? The thought of it is grossing me out…"

"Yeah, sorry. I'll get the Undo Dust…"

After discreetly retrieving the Dust from the lair, Justin and Alex undid the spells that had been performed on Dean. Once all of his parts were back in order and he was able to talk again, Dean's confusion was brimming. He angrily stood up, ready to throw down if needed.

"I dunno what the hell is goin' on here, but you guys are a couple of freaks!" Dean said, pointing his finger at both of them. "How… what did you do to me?? And are you two weirdos goin' out or somethin, cuz that is just really sick—"

"I think that's about all I'd like to hear from you, Moriarty," Alex said, grabbing her wand. With a swift flourish, she said, "Cerebellum Erasus!"

Dean's eyes immediately glazed over, and he plopped right back down onto the couch. He found himself completely unable to remember how he got to Alex's house, nor did he know that anything had happened to any of his appendages.

Alex walked up to Dean, leaning down to put a hand on his shoulder.

"Well Dean, it sure was nice of you to come here and apologize." Alex said patently, looking him in the eye. "I still don't want you coming around here, but I'm thinking this was a step in the right direction for you."

"Yeah…ok…" Dean played along, still completely puzzled.

"Justin, help me out here?" Alex said, attempting to hoist Dean from the couch.

Justin helped Alex heave Dean up and they walked him to the door.

"Bye, Dean! Make sure to head straight home now!" Justin said, implanting ideas as he and Alex ushered Dean away. Dean walked off, still bewildered and wobbly.

"More like, 'jump off a bridge…'" Alex muttered under her breath. "Kinda funny that this time, you were the troublemaker and I'm the one who fixed everything."

"Yeah, I guess the tables were turned this time, weren't they?" Justin said, closing the front door and wrapping his arms around Alex's waist. "So I believe we have some finishing up to do…"

"Oh, you mean that you have some ass-kissing to do for causing all this trouble…?" Alex snickered devilishly, reaching her arms up to wrap around Justin's neck.

"Hmm… by my count, I'd say we still have a long way to go before we're even for all the times I've fixed everything when YOU caused trouble," Justin reached down with one hand and smacked Alex's behind playfully.

Alex squeaked at the mock abuse and said, "Don't you sass me, Justin Russo! I deserve to have my moment!"

"Oh, I'll show you what you deserve…" Justin said, leaning down and tossing Alex's petite frame over his shoulder effortlessly.

"Ahhh!!" Alex squealed. "Unhand me! Unhaaand meeeeee!!!" Alex's voice trailed off as Justin trotted her up the stairs, back to his room.

Once in the room, Justin pitched Alex onto his bed with ease. He crawled on top of her, taking her wrists and pinning them above her head, and he leaned down to hover over her face as she giggled and struggled beneath him. After enjoying watching her squirm for a few moments, he finally planted a deep kiss on her. Alex moaned into the kiss and arched her back up to reach him, though Justin was still hovering above her. He leaned his body into hers, pressing and grinding against her as the heat began to build between them.

Still kissing deeply, Justin let go of one of her wrists to reach down and untie his pants. With Alex's hand newly freed, she took the opportunity to pull on his shirt, trying to remove it. He let her other wrist go, and they both paused the kiss to just undress completely.

Seeing Justin nude for the first time, Alex took a second to look him over. His body was extremely toned and yet smooth and touchable. Though she was inexperienced with naked men, she knew she liked what she saw.

Wasting no time, Alex reached down to touch him. She wrapped her slender fingers around his length, and he gasped with pleasure. His cock felt firm, but warm and smooth. Alex began to stroke him slowly, tantalizingly. Justin let out a deep, sexy groan. After a few moments of touching her brother, Alex's mouth was watering.

Still underneath him, she flipped Justin onto his back and crawled on top of him, putting herself at level with his completely rigid cock. Starting at the base, she trailed her tongue up his cock slowly. Justin gasped heavily, not quite expecting Alex to be so aggressive. Alex's tongue flicked the tip when she reached it, and then she wrapped her full, wet lips around the head. The warmth around his cock caused him to let out a breathy moan.

Alex began to move up and down Justin's shaft slowly, tortuously. He tangled his fingers in her hair, pressing down on her head and bobbing it slowly on his cock. Each groan made Alex wetter, and she wanted him more and more. Justin was so hard that he may have been made of stone, and Alex gradually picked up speed, salivating and making his dick completely wet.

Soon, Alex could hardly contain her desire for him. She abruptly stopped her sucking to look Justin right in the eye.

"I want you, Justin…" Alex said, curtly. "I want you inside me right now."

"Woah… um, Alex… are you sure?" Justin replied, a little taken aback.

"Don't make me beg… I've wanted you for a long time," Alex said as she began to crawl on top of him, trying to position herself over him. "Fuck me, Justin."

Justin battled with his thoughts for a moment. Should they really be doing this? No, they shouldn't be. Yet, they had already passed the point of no return in their relationship, this he could not deny. There was no way that anything they had been doing for the past few weeks could possibly be deemed "normal" or "right". But still… it somehow seemed very right. Their relationship inexplicably felt like the most natural and innocent thing in the world. Their love for each other made them better wizards, better people.

For Alex and Justin, it was right.

Justin acquiesced. He knew that he would have given her what she wants eventually. He always does.

"OK, Alex. You win. But… can I say something first?"

"Oh, please don't tell me you want to pretend I'm a Cylon or something like that…"

"Alex, shut up… I love you."

Alex paused. Though she had known this a long time, she still felt awed upon hearing him say it aloud.

"I love you too, Justin. I know now that I always have…" Alex said, leaning forward to kiss Justin deeply.

Justin reached into the drawer of his nightstand, searching for what could only be a condom. Alex didn't say anything, though she felt somewhat surprised that he was so prepared. Yet, she also knew that preparedness was just typical Justin style.

Finally finding one, Justin tore it open and rolled it onto his still-hard dick. He switched positions with Alex, so that she was once again underneath him.

"Are you really sure?" Justin asked Alex.

"I'm sure..." Alex replied, running her hands up his chest. "Justin, I need you."

He positioned himself at her entrance and began to slowly press into her. Not noticing any flinching, Justin continued to enter her until he hit her barrier.

"Are you OK?" Justin asked. Alex calmly nodded. "Alright… ready?"

"Yes… I love you, Justin."

"I love you too, Alex."

They kissed passionately, and Justin gently thrust completely forward, breaking Alex's wall. Alex let out a pained moan, and Justin stopped moving. Once her breathing returned to normal, she nodded and indicated that she was ready.

Justin pulled out partially, and began thrusting in and out, very slowly at first. Once he could tell that the pain had subsided and was beginning to turn to pleasure, he started to pick up a faster rhythm. Now that he could stop worrying about hurting her, Justin groaned deeply and let himself enjoy the feeling of Alex's tight walls squeezing him.

Alex began to moan again, feeling the heat build. Her legs were wrapped around his waist, and Justin had one hand behind her head while the other squeezed her ass. He pressed deeply inside her, picking up a rhythm. Justin caressed and licked her nipples as her moaning grew louder, and Alex was soon grinding against him as he pumped in and out of her. He picked up speed, and tensed up as he felt his orgasm begin to build.

Alex reached her head up and started to kiss and suck on Justin's neck. He let out a loud groan, as this was a particularly sensitive spot for him. She began to nibble a little and suck harder on the same spot on his neck, and Justin finally lost control and surrendered to his orgasm. His entire body shuddered in release as he quivered and groaned loudly, cursing out of pleasure.

His body collapsed onto Alex's, completely exhausted. His breathing quieted, and he propped himself back up onto his elbows to kiss Alex tenderly. He looked into her eyes, brushing the hair off her forehead, and she had a look of absolute tranquility on her face. Alex smiled up at Justin, and they gazed at each other for a few moments in serene silence.

Realizing that he must be constricting her airways, Justin lifted himself off of Alex, and moved to her side so he could snuggle with her.

"So…" Alex said, finally breaking the stillness, "where do we go from here?"

"Hmm, well… I was thinking maybe ice cream and a nap?" Justin replied, a relaxed smile spreading onto his face.

"Wow… I meant like with the whole relationship thing," Alex said, "but that option works just fine for me. Hmm, looks like I'm rubbing off on you after all."

"Yeah, you might just be… because right now, I honestly can't bring myself to worry about what will happen next."

"Well it's about time you chilled out a little, if you ask me."

"Shh, less talky, more ice cream-y."

After getting dressed, Justin ran to the kitchen and got the two of them a pint of ice cream to share. They both enjoyed some light-hearted pillow talk as they ate, not even discussing their worries.

Regardless of what the future would hold for them, Alex and Justin knew that they now had a permanent bond. Nothing, no one, could ever take away what they felt or experienced. They could only blindly hope that something good would happen for their relationship, and that maybe fate would intervene and allow them to be together. But for now, all they could really do was love each other.

They finished the pint of mint chocolate chip, and curled up in Justin's bed to go to sleep.

THE END.

That's all she wrote! I hope you enjoyed my first fic ever, and it certainly won't be my last. I'll probably start working on my next Jalex once I'm all settled into my new place!

Thank you so much for reading and reviewing! Kisses to you all :)
