She recognizes what you held in your hands

"Ah, the rule changer. I haven't used that in years." She smiles sweetly. Josh looks on in confusion before she sat on the couch with him and explains.

"When I was younger I had inherited a book called the rulebook from my own grandmother before she died. I would later learn she had gotten this book from a witch in exchange for some simple lesbian sex. Don't know what rules she wrote but my bet it was very lusty. I used it to fuck every and any man I wanted, but what I never wrote for is society. Heh, my favourite was making myself a twin in the same body, that was fun." She places her hand on her pussy as she reminisces.

"Hmmm, there was also the time I was in a sexy slapping competition. Anyway, the reason why I gave it to you is that, well you've been so helpful to grandma for the past few years and I might as well since I'm too old for that."

Josh chuckles 'Not for long'

Rule - Everyone stops physically and mentally ageing at 20 and will always look youthful.

Rule - Everyone's libido will not be affected by age and will require a lot of sex to get rid of.

He looks up to see the younger woman that grandma was. A woman who looked briefly confused before smiling with tears in her eyes.

"And you wonder why you're my favourite."
