Karen remembered all the times Jeff picked on her and made her life utterly miserable. So many times she wished he would just grow up and leave her alone... Mentally, Karen was a little ahead on the development cycle and Jeff was a little behind. Its known that boys take longer to grow up but since middle school, Karen was the more mature child. Jeff, although underdeveloped for his age, always had the physical advantage over Karen and she was sick of having to deal with him...
The thought crossed her mind to simply remove him from existence, but being mature, she recognized the moral concerns that posed. She could make him nice to her and give them a good relationship but he missed his chance by being a jerk and then ignoring her when he became a teenager. No, she wanted to grow him up a little and give him a really good reason to stay away. Making him move out would put him at risk of coming back if she didn't make him skilled and independent... she would need to make him better to be free of him for good.
Karen rolled her eyes and bit her lip... "No, I'm not doing this for him, he hasn't earned it. But I am doing this for me, because I do deserve it!"
Karen began working on her brother, making him 20, studying engineering and giving him good grades and a well paying construction job until he finishes school. It made her turn red but she made sure he was ripped, well endowed and instinctively good in the bedroom. If his life ever did turn sour, he would always have a girlfriend he could live with, or get one real quick... She brought his mental maturity from 14 up to 28 causing Jeff to have already started investing in a 401k and IRA. She modified his mental wiring making him extroverted and the life of the party but more independent and not all that interested in family gatherings.
A million tweaks and fixes later and she was ready to send him off to the dorm. Finally setting the reality features for him, her, and the world, she clicked go.
