A shower

Kevin awoke to the pleasant feeling of his half-erect cock nestled between two soft mounds. It took his sleep-addled brain a moment to come to the realization that these mounds were in fact his new girlfriend's firm ass, and that her sleeping form was pressed up against his. Memories from the night before flooded his mind, not just of the physical intimacy they shared—which made his rod harden against his adopted sister's ass—but also of the emotional intimacy and trust. He had told her about Jessica. He was in a real serious relationship and had no idea what he was doing, and he couldn't be happier.

Opening his eyes, he looked down at his petite girlfriend, breathing softly in her sleep. Kevin leaned down and kissed the top of her head, before carefully rolling her off of his arm and slipping out of bed. After making sure Hana was covered up, he made his way across the room to his new bathroom, eager to see what changes his wish had wrought.

He was not disappointed. The bathroom was enormous, with a large walk-in shower and full sized tub with what looked like jacuzzi jets. He walked over to the long counter opposite the shower and used the wall length mirror to really take in his modified body for the first time.

He was the same height he had always been—a bit above average—and he had the same face, if a bit leaner. That was where the similarities ended, however. His hair was shorter, in a more fashionable style, but that was the least of the changes. His body was transformed—what had once been the slightly overweight body of a nerd who spent all his time inside was now the sculpted pinnacle of a high school jock who went through regular training, his former pasty acne-ridden complexion replaced with smooth skin and a healthy tan. Between his muscular legs hung his now familiar, but no less impressive, expanded manhood. He wasn't even fully erect, but still dwarfed his former size—and most other men's for that matter.

It didn't feel real, there was a dissonance between his self-image and the man in the mirror. It was like he was looking at himself through some elaborate camera filter. He spent a bit of time stretching and familiarizing himself with his new physique before realizing he should probably make use of his new shower before Hana woke up.

The shower itself was amazing—easily big enough for two, with two pulsating heads and a bench seat recessed in the wall. After taking a moment to let it heat up, Kevin stepped in, closing his eyes and enjoying the water pouring over his new athletic form. His luxuriating was shortly disrupted by a lithe form pressing up against his back and a small hand wrapping around his member.

"Took you long enough to stop checking yourself out," Hana said in an amused voice, her hand replicating the skills she had displayed the night before and quickly bringing Kevin's rod to full attention.

Kevin was too distracted by the magic his adopted sister's hand was working to shoot back a quick response, but eventually managed, "You know you loved the show."

"Guilty," the petite Korean girl replied, the grin she was wearing clear in her voice. "Now turn around and kiss me you idiot."

Kevin couldn't help but grin at his girlfriend's attitude. That spunky sarcastic personality had won him over at least as much as their shared interests and her nubile body, and he was glad to see it was still around after the previous night's revelations. Turning to face her in the shower, he grabbed her hips and lifted the small teen up to eye level before leaning in to capture her lips.

Hana responded by wrapping her lithe legs around her boyfriend and deepening their kiss, her tongue hungrily entering his mouth. The blue-haired nymph pressed her petite frame tight against Kevin's muscular form, her erect nipples tracing patterns across his chest as she writhed against him.

Playfully biting and tugging on her lover's lower lip as she broke the kiss and pulled away, Hana moved her mouth to Kevin's ear and heatedly ordered, "Enough foreplay. Fuck me against the wall. Now."

Kevin was quick to comply, only pausing to wish, "I wish neither of us will fall," before swiveling and roughly pinning his girlfriend against the tile wall. She had said 'fuck', not 'make love', and he didn't intend to disappoint. He locked eyes with his blue-haired lover, matching her fiery gaze as he lined his oversized tool up with her petite opening and slammed in his full length in one deep thrust.

Hana let out a strangled moan as her adopted brother drove her into the wall, knocking the air out of her lungs at the same time his member filled her completely. He didn't give her a chance to catch her breath, immediately beginning to fervently pump in and out of her tight quim, leaving the petite Korean teen raggedly panting as she desperately clung to her lover's muscular back.

Breathlessly, she managed to gasp out, "Fill me—" a thrust cut her off "—up—" another powerful thrust "—Don't—" yet another thrust "—fucking—" the thrusts continued unabated "—stop..."

Kevin hadn't been planning on it, but certainly wasn't going to now. Staring down at the disheveled girl he was holding up, he was struck with an idea. Continuing to drive into her as hard as his new body allowed, he cautiously moved his hands away from where they were supporting her and watched as she remained in place, suspended in the air—per his wish, she couldn't fall.

Hana, preoccupied with being roughly stuffed full of her boyfriend's monster cock, didn't seem to notice, until said boyfriend reached out with his now free hands and tugged hard on her erect nipples. That made the blue-haired teen's eyes shoot open in shock and elation. She let out a sound that probably would have been a howl if she wasn’t still out of breath, her pussy clamping down on her lover as the unexpected sensation sent her over the edge.

Kevin was close himself, but wanted to push his girlfriend as far as he could before he reached his own limit. Giving her right nipple a final tug, he released it and lowered his hand to where he and his alternative dream-girl were joined, roughly rubbing her most sensitive spot as he continued his powerful thrusts.

The payoff of his efforts was practically immediate, Hana let out another gasping cry and the already intense pressure around his member doubled, pushing Kevin past the point of no return. With a guttural grunt, he buried himself in his partner completely as he once again felt his oversized member pump several heavy loads of his seed into his petite lover. Like before, it was more than just a physical sensation; even after such an **** session, he still felt a powerful connection to the girl impaled on his slowly deflating tool.

Kevin's post-coital bliss was cut short when Hana finally caught her breath and asked, "Um, hun? Great job, seriously, but why am I floating? I've heard of feeling like you're walking on air, but this is a bit much."

Kevin couldn't help but chuckle. Carefully, he lifted his confused girlfriend off of his rod, plucked her out of the air, and gently set her down on the shower's bench. Sitting down next to her, he explained, "I wished that we couldn't fall when we started."

"And you figured out that meant you could free up your hands. Nice," Hana finished his thought. Looking down at her boyfriend's cum leaking out of her, she added, "I think we're going to need another wish."

"Oh?" Kevin asked, curious what the blue-haired beauty could want.

Hana scoffed and rolled her eyes. "Of course it wouldn't occur to you. You're such a guy."

"What?" Kevin asked, starting to feel a bit defensive.

Chuckling and shaking her head, Hana gestured to the now copious pool of cum that had seeped out of her entrance. "I'm not ruling out kids in the future, and I love the feeling of you finishing inside me, but ending up a teen mom isn't exactly on my to-do list," she explained.

Kevin face-palmed. "That hadn't even occurred to me. Christ, I'm stupid."

Hana chuckled again, patting her boyfriend on the shoulder, amusedly countering, "I'm pretty sure you're just a hormone-ridden teenage boy. Why don't you wish that you can't get a woman pregnant unless you want to. Since wishes are retroactive, that will cover last night and any future fun. What you did with that cheerleader too." Her amused tone dropped away at her mention of Cassie, replaced with undisguised hatred.

Kevin was impressed with his girlfriend's well thought out wish, as well as slightly concerned at her animosity toward Cassie. Chuckling, he replied, "I think you might be better at coming up with these wishes than I am." Audibly he added, "I wish that I can't impregnate any woman unless I want to."

"About that," Hana said, her tone uncharacteristically cautious, "I have a request, but it's totally cool if you say no. No pressure."

Intrigued, Kevin asked, "What is it?"

"It's a wish," the blue-haired beauty explained. "I think it would help with getting **** on the popular kids."

Curiosity fully piqued, Kevin asked, "What's the wish?"

"Well..." Hana hesitated a moment, then continued, "I was thinking you could let me make wishes through you. Like, whenever I wish something, you hear it and can make the wish." She quickly added, "Only if you want to, of course. I'm not trying to take your powers or anything."
