'Well, I think that's enough for today,' Rin decided, wiping the sweat off of her brow with the handerchief she had been wearing. She then looked around the common room of her small apartment, located in the southern part of Fire, and sighed. "Mou, I didn't realize how much I've collected over the years!" she exclaimed, walking around boxes of nicknacks, carrying cleaning supplies to the broom closet. As she placed the cleaners back on the shelves, she paused as her hand ran across a strange object. Frowning, she reached for the item, and pulled out a strange three pronged kunai, with a seal on the hilt. Instantly, her mood went south.
"Sensei..." she muttered quietly, running her thumb across the edge of the weapon. She remembered how, nearly fifteen years ago, the newly christened Yondaime Hokage had given her one of his famous kunai as a parting gift, when she had withdrawn from the life of a ninja. Not even a year later, the Kyuubi had attacked, resulting in the final member of Team Minato losing his life. Sure, she and (at least as far as she knows) Kakashi were still alive, but Kakashi was no longer the same after gaining the Uchiha eye, and the war against Iwa had broken Rin's will.
Lost in memory lane, the former medic nin blinked when she found herself in her bathroom, still holding the kunai. "Oh well," she said aloud, "while I'm here, I might as well freshen up." Undressing, she caught her reflection in the mirror. Smiling, she posed in front of the mirror: she cut a damn good figure despite nearing her thirties, and being inactive as a ninja for a decade and a half. Giggling, she began filling her small furo, and rinsed and washed herself outside of it. After that, she gingerly stepped into the steaming tub, and lowered herself so that the water came above her breasts.
Still holding the kunai, she twirled it in her fingers, marveling at the design and purpose of the unconventional looking weapon. The key to her sensei's greatest technique, and twenty years later, no one else had been able to perform it. "I wonder... will anyone be able to use the Hiraishin, or is it just lost forever...?" Rin wondered. Shrugging, she sat the kunai down, and sank lower into the tub, intent on relaxing.
A sudden flux of chakra, noticable even to those without Rin's acute sensory abilities, caused her to sit upright in the bath, just in time to see a orange blur hurtle out of the air into her bath. Water exploded everywhere, and Rin gasped in surprise as the blur landed on top of her. Blinking the water out of her eyes, the woman stared as the blonde head that pressed firmly into her breasts. Then, slowly, two orange clad arms drew out of the water to find purchase on a stable surface, so that the head could lean back to reveal two large, expressive blue eyes, tanned skin, and thin whisker lines.
Unfortunately, the aforementioned hands had found their purchase on the very same breasts the head was smashed up against, thus, it was unsurprising what Rin's first response was.
"PERVERT!" and the sharp crack of skin hitting skin reverberated through the bathroom.
