Nothing, she runs

Arabella can't find words and neither can you...

She slowly, very slowly, grab her dildo and takes it out. Neither of you move or say anything. You almost take a step in her direction, but the look on her face stops you. She puts the dildo at the side and, without taking her eyes off you, put the glass of wine on the table... Her hands squeeze her own breasts as she shows them to you, then shocked with her own behavior she stops.

For a moment you two look at each other, dumbfolded, then she leaves in a hurry

You're so stunned that you don't move at first
You follow Arabella but you can't find her
Maybe she is in her room?

You don't know and you don't know what to do
What you can do but leave?
