As much as he did like Whitney's body, Ian figured that he could always come back. Candice, though - she was a different story. She was here only for a short time, and he had to take advantage of that.
Ian pulled out Whitney's PokeGear and found a small blinking icon from his possession app. He clicked on it, popping up a larger button. He hit that too, and felt his head spin.
He found himself in a familiar room, sitting at a computer. He was in his room. A quick glance down told him that he was back in his body. Not wasting any time, he got up and ran to the box of his old stuff that he had carted over from his brief attempt at the Sinnoh League. He had gotten pretty far, collecting all the badges and making it to the tournament, but he had lost at the hands of Cynthia's Garchomp. Finding what he was looking for - his old Poketch - he poked around until he found his contacts, loaded Candice's number into his PokeGear, and dialed.
The line rang, and a feminine voice answered. "Hello? Hold on a..."
The now familiar dizziness struck Ian as he blacked out again, and opened his eyes to find himself staring in a dressing room mirror with a very pleasant reflection looking back at him. Looking back was Candice, Sinnoh gym leader, wearing only a tiny bright blue bikini. Ian smiled at the reflection, watching the Candice in the mirror return the smile.
Candice's PokeGear beeped, and Ian hit the obligatory 'Auto' button, and continued to stare at his reflection. Candice was a couple of years older than Whitney, and her body showed it. It felt more... sexy and refined. Her breasts, while still large and beautiful to admire, were more proportionate to her body. Her curves were more pronounced, with slightly wider hips and a smoother waistline. Her hairstyle was... still childish, with long black pigtails.
"Ahhhh" Ian whispered contentedly as he ran his borrowed hands over his borrowed body, feeling the velvety softness of Candice's skin. He grabbed her breasts and squeezed. It felt good, even through the bikini. He reached down to ...his bikini bottom - it was on his body right now, after all - and slipped a finger inside, tracing a line down Candice's waist along to her pussy. He could feel himself getting wet and turned on by the sight and the feelings coming from his new body, and it was definitely a more pleasant feeling than when he had been in Whitney a few minutes ago.
Not being able to resist, he pushed his hand further down and began to tease the pussy between his legs, biting his lip with pleasure. He caressed Candice's clitoris, having had enough practice in the last few days to get a much better effect for himself. Within minutes he was on the verge of orgasm, pleasure rising in his stomach as he plunged his borrowed fingers deep into his borrowed pussy. Ian let out a quiet moan as he felt the orgasm release, and stared again at Candice's reflection - thoroughly more flushed, with a hand in her bikini.
Ian grinned. These last few days had been among the best of his life. And the best was still to come, with the gym leader summit - and the beach party - only a couple of days away.
He was pulled out of his lustful thoughts by a voice he recognized.
"Hey Candice! You almost done? Can you help me pick out a bikini?" It was Whitney, and she had clearly followed up on the words Ian had said from her body. So... it seemed the app was even smart enough to clean up after itself, so to speak.
"Uh... Yeah, coming!" Ian replied, hearing Candice's voice coming from his own mouth for the first time.
