Buffy and Spike are swimmers in this (not professional)-
Making Waves by angelic_amy (WIP)
After her parents messy divorce, Buffy and her mother moved out of LA and into the sleepy little town of Sunnydale, hoping for a fresh start. New town, new school, new friends, it was a chance to start over. But life in Sunnydale doesn't run as smoothly as Buffy had hoped, and it has a little something to do with a bleach haired menace she literally bumped into on her first day. Yes, this is a high school fic guys!
And this one is about physical therapy, which means Spike won't be doing very many athletics... but he is a world famous rock climber-
Gravity by Magz
As one of the leading physical therapists in the country, Buffy Summers gets to work with some of the most famous athletes in professional sports. She's never contemplated turning anyone down – until her little sister pleads with her to work on William ["Spike"] Broad [hehe... notice the Billy Idol reference] - the world's most famous rock climber, and a man that she's disliked since their first meeting five years ago. Unfortunately for Buffy, her sister is very good at persuasive tactics, and the blonde soon finds herself shipped off to California with all her belongings, prepared to move into William's lush mansion to give him all the therapy he needs to get back on his feet. Based on the novel Adam's Fall by Sandra Brown. |
