Hi, and welcome to this place. Maybe I'm not the best welcome person, but whatever. If you're into writing a story and contributing here, cool. Please ignore the first suggestion. That dude can have his celebrity story by replacing the names in any other story with his choice. But if you're super desperate for ideas, I got a few. Use them if you want. Just tryin to help.
Ok, idea one. Dorm/apartment setting. Tall girl hanging out on the couch on a lazy morning in pj's, kind of a cold, reserved personality. Reading a book or watching TV or something. In walks roommate or neighbor. She's short, blonde pixie cut; energetic, playful firecracker. Tall girl ignores her and keeps doing what she's doing. Pixie gets a smirk on her face and starts slowly tickling her side. Tall girl notices but does not react. Pixie keeps going, wiggling her fingers under the shirt, teasing her waist - sides -belly - hips. Tall girl struggles not to react, but its obvious this is effecting her. Smiles, but struggles not to laugh. Twitches, but struggles not to squirm. Losing the battle. Pixie starts taunting her. Tall girl finally gives in and lets loose, falling back on the couch. Pixie sits on her and rolls up her shirt, goes to town for a bit. From beginning to now, its like Pixie is in her head: knowing exactly what gets a reaction, which spots are worse, just how to get her going. Finally ends with Pixie letting up, kissing her, surprising but awesome. Something the tall girl secretly wanted. Offer to move to the bedroom. End scene.
Wow, that ran long. I guess just one idea from me. Obviously submitting ideas is selfish, so you don't have to use it, but you did ask. I'll save idea two.
