1: Friends and Benefits by Cotton Nightie Cotton Nightie does a fantastic job pacing this reluctant romance between a college student and his parents regular babysitter, who is still in high school. The first chapter is particularly niceātold from his perspective as he tries to avoid recognizing that he's actually attracted to her.
I should note, this doesn't have any of the power exchange elements in my stories, so don't take this as a recommendation for a dom/sub story. It's not. It's just a sweet, sexual and sexy, romance.
