Vampire Caitlyn needing permission to come inside. Begging crying pleading for Vi to let her get off and it isn't even a control thing for her, she physically cannot come until Vi lets her.
Vi is a greedy lover!! I think a really good evolution of her learning to take things for herself character arc is becoming greedy about sex and I think the jail cell backs it up. Forcing orgasm after orgasm out of Cait because she just likes doing it for her.
Caitvi are big into love marks and you can't change my mind. Sometimes Caitlyn goes into the office with hickeys on her neck, Vi wears a crop top where you can clearly see a bite mark in the clear spots of her tattoo. They're all over each other all the time and not shy about it.
Haters to lovers caitvi where Cait is a doctor and Vi is a pharmacist but they never stop being haters at work. "Dr. Kiramman is on the phone for you to call in a script,"
Vi, arm deep in 1460 gabapentin: "You tell her that she can learn to file an escript or file for divorce"
Vi flopping around in her sleep, and Caitlyn sleeping like a brick so she just wakes up every morning exactly where she was but with Vi draped over her in some new and interesting configuration.
