Trevor send me a nice mail showing me an alternative way to continue with the story after ArianeB has jumped into the pool with her clothes on. Pool scenarios 1 and 2 can be found at the following walkthrough: Will ArianeB jump in the pool with her clothes on?. Obviously I investigated this a bit further and found out that going to the kitchen will trigger the whiskey scenario as well, but this time with ArianeB dressed in a towel (see also: How to get the liquor in the lady?).

Pool Scenario 3

First: How do I introduce myself? 
Second: How to have a steak dinner? 

Go to the backyard.
Go swimming. ArianeB will jump in the pool with her clothes on.
Yell!
Change clothes.
Follow her into the bedroom. ArianeB doesn't seem to mind at all.
Let her finish getting ready.
Go somewhere else.

Dance, Dip, Nip

You can, from here, got to the living room and dance with ArianeB (not unlike: How to do some dirty dancing?).

Dance In the Living Room. Dancing in just a towel is a little ticklish...
Country.
Change music or dance again.
Rock.

...or the other way round.

Rock.
Change music or dance again.
Country.

Stop dancing and go somewhere else.
Go back outside naked.
Go skinny dipping. (see also: How to skinny dip?)
Jump in naked.

Grab her boob.
Romantic.
Go inside and take a shower. Suddenly ArianeB is wearing a towel again. This is a possible bug because a picture of ArianeB entering the shower without her clothes on does exist (enterbath6.jpg).
Follow her into the bathroom.
Continue to watch.
Grab a towel. Now ArianeB puts on a towel.
Take a shower.

Whiskey Scenario 2

Go to the kitchen. The ArianeB suggestion pack kicks in.

I`m out of beer, lets go to the convenience store for a six pack?
Ask if she has got any other ideas.

What do you say we grab some whiskey out of the cabinet and get plastered?
Accept the suggestion.

We have had a whiskey scenario before (see: How to get the liquor in the lady?), but this time ArianeB sits in the kitchen only wearing a towel.

Drink whiskey.
Finish drink.
Kiss her.
Grab her breasts.
Stop fondling.
Touch her pussy.
Stop.

Here`s mud in your eye! ArianeB drinks the rest of the whiskey... and falls asleep.
Finish.
Carry her to bed. You can tuck her in and sleep next to her, but an alternate ending is to:

Call a cab home.
A rather ashamed ArianeB will give you a call the next morning.

(Thanks to Trevor for giving me the tip!)
