The room you had rented for the vacation was the Size Room. You and your girlfriend had chosen this one because you wanted to see how it would feel. Your girlfriend, Clarice, was a bit unsure about it but over time you managed to convince her. Being bigger or smaller sounded to you like a lot of fun. But now that you were at the place and right outside the door to the Size Room, Clarice was getting uncertain again. The door was closed and yellow, with the words "Size Room" written simply on it. But she was hesitant to have the handle turned. This annoyed you a little as you were rather excited at the prospect.
"Are you really sure, honey?" she asked with a bit of apprehension in her voice.
"Of course!" you answer for what feels like the millionth time.
"But, Greg..."
"Think about the possibilities! You can get bigger and me smaller! Or the opposite! We can try different sexual positions and preliminaries! It'll be great! We can try out tons of new things!"
She nods and you open the door, most impatient to see what sort of nice kinks you can see about discovering. The room contains a machine to select what people wish for and private rooms to them experiment.
"What do you want, Clarice?" you say, eyes shining.
"I'm not sure..."
You sigh. Looks like you will have to take the lead.
"Okay! Let's get smaller first," you say, deciding to get the pills to make you both as tall as dolls.
Changing the perspective of the room is bound to be interesting and might prompt Clarice to go further. You then lock yourselves into an empty room, undress, and swallow each a pill. You start shrinking immediately.
