Your mother?

To your surprise, the image in the mirror is not of some green skinned mutant bimbo, but a far more familiar face. Placing a hand over your mouth, you silently study your altered features with awe. Upon closer inspection, you realize that you aren't a perfect replica of Mrs. Applebottom, but the family resemblance is more than strong. In fact, you might even be able to pass yourself off as your mother if the need arose.

But then it sinks in. The experiment must have made you old! Then again, you didn't age half badly, there's not a wrinkle to be seen on your face. In fact, the added age seems to have only made you look more experienced and sultry. What's more, those firm D's have gone up at least two sizes, with only the slightest hint of gravity's toll. Turning around, you admire the back as well, reaching back to swat one of your juicy cheeks to make it jiggle gleefully.

That's when the Doctor announces his presence, making you jump suddenly. "Ah, I'm glad to see that you're awake and alert, Joy." For a moment, you consider covering yourself, but the Doctor's already seen more than a little of your curvy figure.

"Was it supposed to do this? It's not permanent, is it?" It is a prime concern, how would your parents react if you came home a decade or two older than before?

Doctor Philovibe actually let out a giddy peal of laughter. "Well, it was a trial run, but it seems things have turned out for the best. With a little study, I should be able to reverse the formula and it's effects. But that's only the beginning."

That doesn't make much sense to you, how is turning back your age such a big deal? At any rate, you consider charging extra.

"Of course, I am prepared to offer you a greater reward for any future tests."

That sealed the deal. After eagerly agreeing to continue the study, you once more found yourself alone with Helena, this time clutching a very large needle. It's not pleasant at all, but soon they have a sample of your altered DNA to experiment with. Finally, the Doctor himself enters the room, a gleeful grin on his wizened old face.

"I can't thank you enough for your assistance, Joy. I will start working on the "cure" immediately. If you'd like, you may return home and I'll have Miss Helena collect you when it's ready. Of course, you're welcome to stay here while I work, but I must insist you not wander off." While he didn't follow up with an explanation, there seemed to be an unspoken warning there.

Now you find yourself conflicted, you could easily go back home, but until the formula wears off, you'll probably be mistaken for your mom. Your step dad comes back tomorrow morning, which could equally complicate things. But perhaps living in her shoes for a day or two might be fun. Alternatively, Dr.Philovibe's laboratory does seem intriguing, even if it is full of weird things. Either way you get paid, so it's all good in your book.
