"Oh, just thinking of a joke." Ty said, which seemed to be enough for the girl. They walked side by side, with Other Ty sifting through Becca's entire consciousness at the same time.
"So, you've been watching me for a while, huh?" Becca said suddenly as they passed the next house down.
Ty examined her mind and found the question was playful. Interacting with a girl was so much easier when you could literally read them.
"How could I not?" Ty grinned.
Other Ty experienced a sexual thrill at the compliment, and learned Becca had never had a boyfriend. He felt her clit poke out a little, which made the actual Ty blush a little.
Becca simply smiled. "Yeah, I saw you checking me out."
At that moment, Ty tried something else. He froze the entirety of time for himself. The world simply paused, generating an eerie silence.
"Wow." Ty grinned, noticing even Other Ty was frozen. He could freely move around and do everything normally. So like a good horny boy, Ty stopped in front of Becca and kissed her cheek. Then he kissed her lips. She was smooth and soft, and smelt of sweet perfume. This made him incredibly aroused, so he slowly and sweetly kissed the frozen girl again, relishing the flavour of her lips and slipping his tongue into her mouth. Minty!
For good measure, Ty opened her jacket and admired her young breasts. Big and pert, held in a lacy bra. He cupped them in his small hands and marvelled at their size and squishiness. Much more than a handful. Then, letting his boner go down, he stopped molesting his frozen neighbour and let time resume again.
"I guess I liked what I saw." Ty said, not missing a beat. They resumed walking again.
"Well." Becca giggled. "It's like we've known each other a long time I guess, but neither of us did. Weird, right?"
Ty willed Becca's already substantial chest to grow a little more pronounced, which it did pretty much instantly, and smiled as her jacket and top filled out a little more, getting only a startled glance from the girl.
"About time we did something then." Ty nodded as they reached the end of the street, feeling deep amazement at his new abilities. He checked in with Other Ty and grinned to himself as Becca realized her boobs seemed tighter in her bra and somehow a little heavier.
