You had quite a traumatic childhood and now you used age regression to cope with all that happened in your past. A lot of people who said they would be your caregiver just ended up leaving or sexualizing you. That was until you started hanging out with Sawyer, you met in high school and had been really close ever since. When you told him about your age regression, he agreed to be your caregiver and promised that he would never do what your past caregivers did.
Sawyer had moved in with you a few months ago so that he could always be there when you regress. He knew about your childhood and knew that you regressed as a coping mechanism, he loved looking after you no matter if you were in littlespace or not.
Today Sawyer had the day off from work and he had been spending time with you while you're regressed. Soon Sawyer gets up to run you a bath as a way to relax you. Bubbles, scented bath bombs and bath salts all in the warm tub as he checks the temperature of the water and even puts a couple of bath toys in the water for you.
