(Sorry if there were plans for this option, I had a few ideas that fit this description so I decided to start it)
Alex had lived her whole life around girls, all different kinds. Between her family members she had lived with: the overly playful who loved to mess with her size, the uncaring who wouldn't even bother to check if they heard her squish beneath their shoes, the outright cruel who abused her tiny stature, and everything in between. After 18 years of this experience, Alex is finally moved out of her childhood home and ready to face whatever else the world has to offer. But how can a girl only 2 inches tall hope to survive in the world all on her own? Well, she doesn't. And this is where her girlfriend Chelsea comes in.
Alex and Chelsea met in highschool, Chelsea being a transfer student had only heard rumors of a tiny, 2 inch tall girl around the halls, but never really understood it. That's why when she spotted an empty seat in her biology class she didn't look as closely as the other students had learned to, and simply sat down. Now, Chelsea was by no means a big girl, in fact, she was an absolute knockout. Tan skin, toned body from working out, beautiful brunette hair, the works. But for some reason, no matter what she did, she couldn't get rid of her absolutely massive, jiggly ass that stuck out of her like a couple of basketballs shoved into a pair of yoga pants. So when Chelsea sat down, she did it with force. Little did she know, but her act of sitting had completely obliterated your tiny body into her enormous buttcrack. This was the first time of many you and Chelsea's butt cheeks would have a little ménage a trois, but the second she reached in there, pulled you out, and brought you around to her face, the rest of the world melted away. She apologized profusely and asked if she could do anything to pay you back for her mistake, you asked her out then and there, and the rest was history.
Chelsea was a ditz through and through, she's squashed you against her body more times than you can count, but she loves you and accepts you for who you are. For this reason, you decided to move in with Chelsea in a single room apartment as you both head off to attend college. This leads us into the story, where you and her are...
