Ty closed his eyes and concentrated. He had retroactively altered Dustin's entire history before. Now he concentrated on doing that again. She was Dusty, his 13 year old step sister. And like the old Ty, Dusty was a very late bloomer. Though 13, she possessed the body of a 10 year old. June and Mark were concerned about their daughter's growth and were considering hormone treatments. Dusty was crying because the other girls at school had been mean to her at school this last week, tossed her locker, and hung her upside down from the swings. She was confiding in her loving step brother, the older Ty.
"There, there." Ty whispered, holding Dusty close. "I know those other girls were so mean to you, sweetie."
"Everybody picks on me!" Dusty wailed. "It's not fair! Why won't I grow up? Did... did I do something wrong?"
In between sobs Ty made more alterations. Dustin's room changed to that befitting a 13 year old. The walls turned pink with pretty white flowers. The xbox, all Dustin's metal CDs, and other stuff turned into a toybox full of girly toys, some pop music, and pink girl themed furniture. The oversized jersey changed to a little brown and pink dress.
"It's not your fault, honey." Ty consoled, watching as the tiny girl leaned back and rubbed her bloodshot eyes free of tears.
"It... it isn't?" Dusty sniffed.
"Of course not! Some people just take longer to grow than others! Why, I'm sure in a couple years you'll become a beautiful young lady! And then the other girls will leave you alone!"
At this, Dusty smiled and threw her arms around her step brother's neck and gave him a sweet little peck on his cheek. "Awww, Ty! You always know how to make it all better!"
The older 15 year old smiled slyly. He had liked that kiss. He willed Dusty to kiss him on the lips rather lovingly.
The 13 year old obeyed immediately, leaping forward and kissing Ty square on the lips. When she drew back, her eyes were wide and she was blushing. "S-Sorry, Ty! I guess I got carried away!"
Ty giggled. "It's okay, Dusty. I like you kissing me." A lot, Ty thought. He willed Dusty to kiss him longer, more intimately. He wondered if the old real Dustin was in there somewhere, humiliated.
The 13 year old gently leaned forward this time and very tenderly kissed her step brother on the lips, her tiny mouth gently smacking against his and sucking in a way that a 13 year old shouldn't know. She drew away and saw Ty's surprised face, blushed, and smiled back nervously. "Like... like that? Is that how boys your age want big girls to kiss them?"
Ty, too, was blushing. This was criminal! "That was very good, Dusty! I bet other girls your age can't kiss like that!"
Again the girl blushed deeply and swayed nervously with her hands in front of her dress. "I... I think I like it." Dusty said simply. "It's making me feel all..." The girl was confused by the sense of arousal. "Well, like, good and stuff."
"Want to try it again? Want to show me what a big girl you are?" Ty leaned forward, sitting down on his knees and grinning. He willed Dusty's undeveloped body to progress forward just a little bit at a time every time they kissed now, and for the young girl to be completely aware of it.
Dusty kicked the floor nervously and then grinned. "Okay!" She said sweetly, and again laid a kiss on her step brother. Ty's eyes widened in amazement as his desire became reality. As she kissed him softly, the little girl began to grow up. Just a bit, but enough to be noticible. She grew an inch taller, her shape became a little more feminine, and the slightest swelling of her chest indicated puberty was starting. When she finally broke the kiss, Dusty was easily a girl of 12 now.
"Dusty!" Ty feigned shock. "Look at what happened to you!"
The girl's eyes widened and she looked over herself. "W-What?" She looked around her back and front and then her jaw dropped. "Whoa!" She looked at Ty excitedly, and jumped up and down. "Ty! Look! Look! I grew! She touched her budding breasts in wonderment and smiled. "I-I'm almost like the girls in my class!"
Ty blushed and wondered where this was going. "It must be kissing me, Dusty!" He laughed. "Kissing an older boy is making you an older girl!"
"Wow! Really?" Dusty's eyes went wide. "Is that... supposed to happen?"
"Oh, sure!" Ty lied. "I've heard of it but I didn't think it was real!"
"Wow!" Dusty repeated, letting out a long gasp. "What happens if we kiss again?"
"Maybe you'll grow again!" Ty said excitedly. "Want to find out?"
