I want to show off the black dress variant, it follows the “Things NOT to do in a dress” beginning:

We’re going to start with “Steak Dinner” this time.

Go to the bedroom and put on a swimsuit

Change into a swimsuit yourself

Go to the pool (but DON’T SWIM)

Go back to Ariane’s house

Go inside

Get dressed and go for a drive

Get dressed yourself

Get in the drivers seat

Go Downtown

Lingerie store

The upshot here is that if Ariane asks for inexpensive, you can pick just a bra or just panties, and Ariane will be partially nude in the changing booth

Agree to drinks at the club with Ariane and Rebecca

Buy the next round of drinks

Let them continue to dance

There are a few versions of what happens depending on how Ariane is dressed.

Once you are back at Ariane’s there are a few possibilities here, lets start with:

Follow Rebecca
No, it wouldn’t be too presumptuous
Strip naked and join Rebecca in bed

or we can go with:

Wait in the hall
Go to the livingroom
Kiss her
Run fingers through her hair
Massage her shoulders
Kiss her
Grab her breasts
Rub her thighs
Ask her to take her dress off
Grab her butt

Or avoid the living room all together:

Go to the kitchen
