To find out how big you can go

Stepping back out into the sunshine, you couldn't keep a grin off your face. You still weren't sure how the hell this power had come to you, but it had already been the best day you'd ever had by a country mile. You ran down a mental checklist of the lasting things you'd done with your power so far:

• You'd arranged an appointment with your classmate Terra tonight at her place, supposedly for some "private help" with an assignment. Thinking about her fiery red hair and impressive chest, you doubted there was an awful lot of studying that would take place.
• Then you'd met your lit professor and tested out your power a little harder, basically turned her into your loving ****. You...probably shouldn't have done that, you admitted, but turning her back wasn't going to happen. In case things went wrong with the power, you wanted someone who would be unequivocally on your side, and one of the faculty was too good a choice. Plus, you know... Love ****. Even if your brain was inclined to turn her back, your cock wasn't having any of it.
• After that, you'd had your little interlude with Nakamura. Not only had you taught the bitchy professor a serious lesson, but you'd learned something crazy about your power - it went beyond changing things in the present, you'd modified her entire past! Sure, you'd done it just to give her a luscious ass, but the point was it worked.

Messing with Nakamura had been a hell of a rush, but the bit you couldn't stop thinking about was how you had apparently changed her personal history by giving her the choice to have a perfect bubble butt "since her freshman year of college." Had you really changed the whole world, influencing years of interactions with her, or did she just remember things differently? She said she remembered having such a perfect ass since then, but still knew you'd changed her; that didn't tell you much, though, since you'd been pretty blatant about doing it right in front of her. You could somehow remember both her old butt and her new one, but you had the power so things were probably different for you. Neither of you were a great metric for how thoroughly your power had really altered the past, and you didn't know enough about Nakamura to go interview her friends or whatever.

For a moment, you considered going back in to her class to grill her for some more information, but then a blonde walked by in a skimpy little sundress, and your libido informed you there were more fun options available for testing your limits. You grinned again and walked out onto the path, looking for the right person to ask a few very personal questions to.
