Weeks later...

As the time goes on, you get used to have Amy permanently around; meanwhile, you use your own ring less and less, until eventually you stop using it entirely. As much as you enjoy your time as Jess, you don't want to end up addicted to using the ring as Andy is.

You and Margaux are getting along very well, and not just because of sex: you couldn't exactly say why, but you like her in a way you never liked Isabella.
Margaux is spending a lot a time with you and Amy, and while nothing has happened between them since the party, the attraction between them is obvious.

You haven't had sex with Amy since you and Margaux started dating, and while Amy is constantly teasing and provoking you, she hasn't waited much before finding other partners. You have no idea with how many guys she has slept, but the number is getting higher and higher.

It's now the end of October, and it will be Halloween in a couple of days. You weren't planning on anything specific, until Amy came to you with a proposition.
