The fan-fictions I write are based off of role-plays done by myself and my role-play partners that have consented to let me make these. Credit goes to Sarah, Ren, and Chelsie. Thanks for helping me, guys. 
Also, I'll probably post more than just DaveKat here. Mostly the ships I role-play/write about are CronKri, DaveKat, and Stridercest. Most if not all of them will contain smut.
I'm always up for a role-play, by the way, so just hit me up if you want to.
