Alien Adventure/Sit and wait
From Create Your Own Story
You sit and wait. Through the window, you can see the stars whizzing by. After a while, the room begins to shake, and you are sucked up into a tube. As you're going through, you see your girlfriend being strapped down by more of the suited aliens. The tube you are in tapers down, getting narrower and narrower, yet you're not squished at all. You drop out of the tube, onto huge grains of sand. The sand isn't the only huge thing around--your girlfriend is a giant compared to you, and you're sitting right next to her clit.
You determine you must be in a desert as you see the spaceship zip away in a flash of light. And you're now naked and ant-sized. To make matters worse, your girlfriend doesn't even know you're there!
