*I got to wear panties again today.*
Jeff had been living his older sister Emily's life for a week now, and he couldn't believe how much he was loving it. Spending two weeks as his mom had been a fun way to see what life is like for an older woman, but that was nothing compared to what it was like being a hot girl in her senior year of high school. Jeff had initially been worried about how he would slip unnoticed into Emily's social life, to say nothing of doing schoolwork three years ahead of where he was himself. As it turned out, though, the adjustment had actually been really easy. Jeff had always been a better student than Emily, and though he did have to spend a couple days catching up, her classes were not all that hard, especially since they were approaching the end of the year and most of the classes for seniors had checked out, teachers included. And, in a real stroke of luck, it turns out Emily had written a really thorough diary that Jeff found in her desk drawer while examining the room that first night.
*I got to wear a bra again too. The pink one, with frills.*
Jeff spent a good amount of time that night reading Emily's diary, and he had gone back to it every day after school to remind himself of who was mad at who and why someone couldn't be talked to and all that. And he found it helpful (not to mention therapeutic) to write down notes on how the day had gone and what he'd need to remember to keep fitting in as Emily, so he just wrote it all down in the diary. After only a few days he no longer needed to refer to the diary for reference, but he kept writing in it anyway. He thought it funny and kind of appropriate to have some continuity between old Emily and new Emily. He loved nothing more than writing about how great it was to be a hot chick.
And he loved being new Emily. First off, it was just really hot being a hot girl. Obviously Jeff had never lusted after his own sister before, but now that he was in her body, he could appreciate it without shame. And the truth was Emily was just hot. Jeff spent quite a bit of time in her room, trying on different sets of bras and panties and admiring his new body in the mirror. It was even a thrill for Jeff just to go about normal life, knowing that he was wearing sexy underwear under the clothes he had on. He loved showing a little bit of bra strap just to let everyone know what they were missing. And honestly, people just wanted to have Emily around: she was popular in school, and even random people in public seemed happy to have a pretty girl around in a way that Jeff had certainly never experienced as a guy.
Overall, everything in Emily's life was just easier, and more fun, and a lot hotter than back in Jeff's old body. And with the school year wrapping up, Jeff/Emily had a whole summer of freedom to look forward to before starting college in the fall.
But it was Friday night now, and Jeff had big plans for Emily's body.
