She continued, "We're not done yet, I want the full experience of being a old mature woman."
You noticed that she started to concentrate again. Her sundress shimmered. While it was somewhat ill-fitting after her change it now seemed to perfectly hug her older body. You could also see her baggage change. You could spot a crop-top changing into a more mature blouse, a pair of sweatpants changed into a dark red skirt, and numerous other changes, some noticeable, or insignificant.
"This is so strange." your girlfriend exclaims. She pauses for a bit before she continues, "You're so young. You're barely an adult." She stared at you. Her brow furrowed, wrinkling her forehead.
"Do you want me to also change?" you ask her.
"No. It's just different. That's all. I don't mind dating a young stud." your girlfriend says while smiling mischievously. You recognize that smile. Even though her body and mind is older, she's still your girlfriend.
"But it's a really unique experience. Even though I know that I was your age just minutes ago, it feels so distant. Part of me feels like it's twenty years ago I was anywhere close your age."
She paused for a moment, then she said . "You know what? Lets explore the resort. We can lounge later. I want to walk around as this new me."
