You and Vivian have been best friends since seventh grade, when she defended you from bullies and then beat you at basketball later that day. Your friendship has always been defined by playful competition and easy intimacy—sharing snacks, staying up late talking, and wrestling on the floor over the last slice of pizza. Neither of you has ever mentioned the growing tension between you, the way your hugs linger longer than necessary, or how you find excuses to touch each other "accidentally."

Today started like any other Saturday afternoon: video games, junk food, and Vivian accusing you of cheating at Mario Kart. The argument escalated into your usual playfighting, rolling around on the couch until you suddenly found yourself on top of her. When you tried to push yourself up, your hand brushed against her breast, and time seemed to freeze.

She gasped dramatically, eyes widening in mock outrage. "Accidental my ass, you just wanted an excuse to touch my boobs, you little perv!" she exclaimed, though the corners of her mouth twitched upward despite her stern expression. She shoved you playfully but made no move to create distance between you.

Before you could apologize properly, she straddled your hips, pinning you to the couch with surprising strength. Her hair fell forward, tickling your face as she leaned in close. "This definitely calls for revenge," she whispered, her hand hovering over your chest before giving it a light squeeze.

She pulled back slightly, a mischievous glint in her eyes. "But we're not even yet," she said, tracing the edge of your shirt with her finger. "Why don't you 'accidentally' touch my butt and find out what happens?" Her tone was challenging, but her body language told a different story—her hips pressing against yours, her breath coming faster than normal, as if she was waiting for you to make the first real move.
